Critical Thinking Skills Assist Sound Decision Making

Before opening this specific topic, let's agree about why an answer is important.
1) If you're a chicken, this is already a pandemic and there have been huge consequences already.
2) If you're a chicken (or turkey, or duck) farmer, knowing the answer may enable you to take effective action to prevent loss of your livelihood, and relieve you from doing things that won't make a difference.
3) If you are in a position of authority to control poultry transportation (both legal and illicit), or to augment poultry biosecurity, or to increase effective surveillance in poultry or wild birds, then perhaps an answer might lead to a solution to the problem.
4) If you are a human (farmer or not), you might shape your food choices, travel plans, or recreational reading list based on the answer, but please don't base your emergency preparations on it. If any emerging infectious disease (from any source) that has a significant "attack rate" and a non-trivial "case fatality rate" (or case morbidity rate) mutates to spread human-to-human, then the question of its etiology becomes irrelevant.
Clearly, people should be preparing for a probable near-term pandemic, regardless of the answer to this question. Said differently, if you are trying to gage the threat level, or make decisions regarding emergency preparedness, it doesn't matter what mechanism(s) are facilitating the spread, unless that answer affects the outcome. So far, it hasn't. In all probability, it won't. During H5N1's spread over the last 5 years, and 4 continents, and into dozens of countries, and causing thousands of wild bird deaths, millions of domestic poultry deaths, and hundreds of human infections, the answer to this question has been irrelevant. Don't harbor false hopes that there is a simple solution that hinges on "spread via poultry trade" and that once addressed, the problem will go away. People have been doing much, in many ways, simultaneously, to combat the spread, and H5N1 has marched right through; extensive vaccination, increased biosecurity, poultry trade blocks, rural education programs, etc. The message for the average person is .... "Prep. now, and ask questions later". Now, on to answering the question.....
==================================================================
I thought this thread was a particularly appropriate topic to explore the basis for belief in ANY position, particularly when we feel a need to make decisions based on that choice, and supremely when the decision carries the potential of huge consequences to our health and life itself.
How Do We Know Anything?
We either learn it for ourselves, or we accept what someone else says as the truth. Since learning everything for our selves is way too slow, we rely heavily on accepting data and conclusions from others, that seem to "fit" with the preceding stuff that we have accepted as true. Despite starting out in life at essentially the same "zero" point, the numerous variables in personal development leads to a vast diversity in what each of us knows later in life. Nobody can know everything, hence we rely on specialists. We rely on each other. By the time people are adults, it is likely that the unique combination of life experiences has caused each of us to become a specialist in something, even if we aren't aware of it. This is what makes everyone a valuable part of the whole. What has become more difficult, as the world's collection of knowledge has increased exponentially in recent years, is to be able to confidently access what you need to know, when you need to know it. The question in this thread is how to weigh the disparate and competing arguments on the mechanism(s) of the spread of HPAI H5N1. The challenge is to sort the sound information from the dis- or mis-information.
What (and whom) should we believe?
What you can believe of what someone tells you is based on their knowledge, coupled with their honesty. If they don't truly know, and neither do they have the "most informed opinion", their honesty is irrelevant. Even if they do know, if they are dishonest, either deliberately, or by sloppiness, then their conclusions are less than worthless. The greatest difficulty occurs when specialists, of equal gravity, or publications of seemingly equal yet sometimes inscrutable credentials, disagree. That is when we must dig a little deeper or "read between the lines" to find the truth. We should employ "critical thinking skills" to establish credibility, examine authority, probe hidden (or visible) agendas, and observe discrepancies. If you don't know a particular topic, then "know someone who does".
Like the old saying about buying a used car, "If you don't know cars, it's good to know someone who does know cars". In this case, it becomes important to "know" the contributors to this forum.
To answer the question above, let's dig into the two sources of information, and the motivation(s) behind the two sources of information.
 
Re: Power of Negative Thinking (H5N1 in Pakistan)

Re: Power of Negative Thinking (H5N1 in Pakistan)

Dr. Niman: Dr. Niman is a specialist. If you are concerned about HPAI, you want to know Dr. Niman.
When Dr. Niman posts the long scrolls of sequence accession numbers, it may only be directly valuable to 5% of the readers, but indirectly, it should be valuable to everyone, here's why. People's knowledge equals what they have learned, minus what they have forgotten. How much they learn is a function of their intellect multiplied by their focus. Dr. Niman's PhD credentials lend assurance to the "significant intellect" part. The sequence data, and phylogenetic graphs, are a hint at the depth of focus that he brings to bear on this subject. Do the math, and you quickly see that "how much he has learned" is profound. Listen to his recent audiocast (on Silver Springs radio), and peruse his prolific archives at Recombinomics.com, and you will realize that he doesn't forget much. He has immersed himself in the; facts, dates, places etc. of this emerging disease in an objective and scientific way expressly to discern the cause-and-effect relationships involved. His "local" maps may be open to various interpretations based on the proximity to transportation utilities, but step back and spend some time with the global maps, and there is no doubt that the long-range spread is from wild birds.

See http://www.recombinomics.com/maps.html and http://www.recombinomics.com/H5N1_Map_2005_QinghaiL.html to view the 'May 2005 to Dec. 2005, first massive spread of HPAI' moving west from China. It might take some time to get the colors & dates & 'wavefront' progression visualized (it is worth it), but treat yourself to the step-wise 'animation' by continuing to click where it says ?(click map for May)? or click anywhere in the map. Keep clicking to cycle through the 'loop'. In case you are not fully familiar with the Recombinomics.com website, click on 'what's new', then click 'H5N1 Egypt and Ebola Maps'. In the list, find 'H5N1 Wild Bird Flu World Map February'. There are other maps in the list that detail subsequent spread into Africa and Europe (very revealing).

The most important word from above is "objective". Dr. Niman's primary interest is in following the genetic evolution of a virus. IMO he is only interested in its mechanism of spread if that understanding helps his access to the genetic sequences and their geographic locations over time that provide evidence of the mechanism(s) of their evolution. If the mechanism of spread were 100% poultry trade, I don't think it would have changed things much for him. He would simply have "followed the virus" and his global maps would reveal the trade routes, instead of migratory bird flyways. The timeline would instead track the mutations starting in one place (or several), and follow the certain routes and dates driven by other factors such as religious holidays that emphasize eating poultry, or shipment dates of (or bans on) exports/imports. He acknowledges this component in the Bernard Mathews event.
What I am saying is that he argues this, not because he has a vested interest in it being one way or the other, but simply because he cares that people "get it right". As a Flutrackers contributor, he puts in far more than he takes out. For example, his local 'outbreak maps' are meant to document geographic clusters, not so much to substantiate the global spread mechanism. He shares this product of scrutiny with the community, for our benefit, not his. Also, he has answered "the basic questions" repeatedly, and with only slight sign of impatience. He is a rock.

When someone tells the truth, when doing so is easy, they get almost no increased credibility. But, when someone tells you the truth at some personal expense (time, effort, money, emotion) or risk (professional or personal) then their credibility soars. Dr. Niman repeatedly makes predictions about where, or when, or what strain will show up next. He doesn't have to do this. He risks his professional standing in doing so, but he thinks it is important and has sufficient confidence to "call the pocket". (...Henry, please correct me if I've got it wrong here!) He has my respect and admiration. Even more, he has my trust.
 
Re: Power of Negative Thinking (H5N1 in Pakistan)

Re: Power of Negative Thinking (H5N1 in Pakistan)

Who's on the opposite side?:
Endangered Species at World Wildlife Fund. At WWF, we are the leader in wildlife conservation and preservation of animal habitats around the world. www.worldwildlife.org/ a charitable trust, founded in 1961. (aka The World Wide Fund for Nature) The group says its mission is "to halt and reverse the destruction of our natural environment"

Birdlife International at www.birdlife.org/ is also concerned with; threatened species, threatened bird habitat etc.

The article refers to ties to the Royal Society for the Protection of Birds (RSPB) http://www.rspb.org.uk/ . This group has the word "Protection" in their name. They have a vested interest in the public's perception of the cause of the spread. They have every reason (every political reason) to adopt their stated position. If they were silent on the issue, their support would dry up. If they stated that wild birds are primarily responsible for the spread of this disease, they would be committing organizational suicide. We would expect them to deflect attention away from the birds as a cause.

.......as such, we should be able to quickly recognize that these groups have a visible agenda. They are not noted for 'middle of the road' rhetoric. They feel that they are the champions of underdogs who have no voice, so they tend to yell about stuff, to compensate. It is important for readers to find out who is doing the talking, what their agenda is, and how to 'calibrate' for the tone (and volume) of their publications. They spin stuff to attract donations to their cause. They are entitled to their opinions and their perspective. However, if their fervor runs too far, and when 'spinning' the facts devolves into misrepresentation, then they deserve public reproach.

Re: Power of Negative Thinking (H5N1 in Pakistan)

About 'negative' data: Let's say that you have a page of data. It's mostly filled with zeros, with a few Xs sprinkled about. The WWF is hoping that you will ascribe equal importance to both zeros and Xs. What Dr. Niman points out is that there is a huge difference. There are many ways that a test can return a zero, called 'negative' data..
  • They test blood (less sensitivity) instead of mucus swabs.
  • The test is too early or too late to catch the rise-and-fall of the antibody concentrations.
  • The sample degraded before the lab worked on it.
  • The 'primers' for the RT PCR were poorly chosen.
  • The chosen test is simply not sensitive enough to detect the existing levels of virus present.
  • You can't test all of the birds in a population, and only some are infected at one time.
  • Willful mis-handling of data or politically motivated "mis-interpretation".
  • Just because you can't see it doesn't mean it's not there.

Conversely, everything has to go 'right' for a test to return an X, called 'positive' data.
  • It's almost certainly actually positive (called specificity) and 'when you can see it, it's definitely there'.
When Dr. Niman calls it "negative thinking", I think he means "thinking based on 'negative' data", which is to say, conclusions based on a page of data that's mostly zeros. Of course he takes issue with this because the empirical data, the Xs, are the true milestones that describe the path of interest, not some fog-banked empty fields to either side.
 
Re: Power of Negative Thinking (H5N1 in Pakistan)

Re: Power of Negative Thinking (H5N1 in Pakistan)

Truth is often found to be not at either extreme, but somewhere in the middle. The middle ground in news articles is best established by a series of short, declarative sentences, such as;
1) Wild birds (both migrating and locally persistent) have been shown capable of H5N1; infection, asymptomatic carry, transport, and transmission to other birds and to mammals, including fatal effects.
2) Poultry trade (both live birds, butchered birds, and infected feed & bedding) have been shown capable of H5N1 transmission and infection, with fatal effects.
3) Experts differ in regard to the relative proportions of each mechanism's responsibility for the current spread, but agree that efforts should be made to isolate these transmission vectors from each other, and from humans.

I would like to compare the above example of truth-in-reporting to the post # 1 content.......since I too felt that the "news" article in post #1 is full of 'spin-words', such as "but they are not the main source of " and "there were no sound grounds to support the allegations that migratory birds were solely responsible for the spread of H5N1." I also take exception to claims such as; "no fully documented migratory wild birds have tested positive for H5N1.", and "mapping of bird flu outbreaks across the world had shown that they followed poultry trade routes rather than the migratory birds' flyways". (bolding is my emphasis) The words 'fully documented' are vague weasel words, plus the statement is false. Also, if they are going to refer to mapping, there should be a citation to go with it. Equal blame should go to the Daily Times in Islamabad for printing a press release from WWF as a news article. The reporter's source is WWF statements, not objective research, and devoid of fact checking. I counted "The WWF said" , or "The organization said" or " according to a statement issued by the WWF" or "it said" 14 times. Additionally, they employed the phrase"it was concluded" regarding poultry trade vs bird migration. Be suspect of assertions couched in the third-person passive voice.

It is much to Dr. Niman's credit that he goes out of his way to draw our attention to the claims that conflict with his own. If he didn't put this ProMed commentary on Flutrackers, we might never have seen it, but he cares enough that he wants us to know it's out there, and then exposes it for the rubbish that it is. This behavior shows good character.

Re: How to Think Analytically

Perhaps some of the regular contributors to Flutrackers wouldn't mind providing a brief personal bio. (or a link to it in their tag -line (signature), so that when people first find the site, they can quickly gain insight into who they are reading.
Not everyone needs to be a scientist, but everyone has a responsibility to employ their "critical thinking skills", and dig through the historical background to assure adding value, not diluting energy. I believe in the saying that “rational minds, equally informed, seldom disagree”, so I have attempted to provide some references and commentary so that we are all more equal in our information. Using the 'search-box' with the 'radio-button' set to 'www.flutrackers.com' and entering some keywords such as 'migratory birds', 'global spread', or 'dead birds don't fly' might help.
Also, emotion is the enemy of objectivity. A dispassionate approach supports a clear-eyed perspective. Perhaps instead it should be called 'passionate objectivity' to reflect the zeal for fair and factual information that Flutrackers pursues.
I also believe in the saying that "a person is only as good as their trusted circle of friends". We each rely on reality-based and ethical feedback from others to establish and maintain our own moral foundation. This is one of the primary bi-directional responsibilities in any community. In that capacity, the Flutrackers (forum) community excels. I thank you all.

Re: How to Think Analytically

Re: How to Think Analytically

Sorry, it's not my intent to malign anyone, I only take exception to behavior that is destructive. I love the natural environment. I support the stated goals of those organizations. I deplore their actions when they put people's lives at risk to further those goals. Their words don't just fall on the ears of their volunteers and financial supporters. In this networked world, those statements may influence people to dismiss the reality of the potential high-consequence and global threat to human life too, which I also love and support.
Thanks for all that you do Florida1, and I will get better at knowing where the line is.....

Re: How to Think Analytically

Re: How to Think Analytically

Thanks for the thoughts read. As I like deductive reasoning it is very much up my street but, as always, it requires an acceptance of stated, or implied, premises and we need to be careful that we are aware what those are. Which leads me to the RSPB & WWF where your implication is that they are spinning to protect the 'reputation' of the wild birds. You may be right but if you are I am not sure they (the RSPB & WWF) are. The RSPB aims to protect wild birds primarily but studying them and lobbying for the protection of key feeding or breeding sites. Why would an organisation that has these aims, and a firm scientific foundation, think they are acting in the birds' best interests by denying they are ill. The wild bird population is a victim just like domestic poultry, poultry keepers and those humans unlucky enough to have caught this zoonotic. If they accept that HP AI H5N1 is endemic in the wild bird population in large parts of Asia, Africa and Europe - and is likely to increase its geographic range over time - then they can lobby for wild birds to be included in any control and containment plans. This opens the option for government funding, protection of habitats (to help keep wild birds away from humans and domestic animals), enhanced testing (to find the real levels of sub-clinical infection and any reservoirs of resistance), input into culling and vaccination stratergies etc.
 
Re: How to Think Analytically

Re: How to Think Analytically

Welcome ///read///!!!
What an interesting post. It seems that you have been reading here for a while and I'm glad my conversation brought you out of lurking.

Actually, Niman had pretty much given me any answers I was looking for and I was finished with the original thread. However, since you put a lot of thought into this post, I feel it would be kind of rude of me to not comment.

Instead of making this post about thinking analytically in general; you made it about why I should believe Niman over other people. I have no desire to make this about a particular person; I would ask the same of anyone who gets up in open forum and issues strong statements.

The wildlife organizations you brought up...I have done no research on them so I cannot address the motives any of those organizations. What I can talk about is the Global Avian Influenza Network for Surveillance, which is the group that Niman and I have discussed before. http://www.gains.org/ I read their recently updated 7th quarterly narrative report for 2007 and I honestly don't see any kind of intentional deceitful actions on their part whatsoever.

What I do see is an organization doing a great job with a huge undertaking. Here's an example:

Southern Africa (South Africa, Zimbabwe, Mozambique, Botswana)
Dr. Graeme Cumming continues to lead GAINS efforts focused in the GAINS Southern Africa sub-region, including field surveillance and migration studies. Highlights include:
Surveillance:
In South Africa, 1550 birds have been captured to date over the course of 16 sampling surveys in five locations; many of the birds were sampled at three sites visited regularly: Strandfontein, Barberspan, and the Manyame catchment. Preliminary sampling was conducted at Rietvlei, a wetland near Strandfontein. In Mozambique, field sampling trips were made to Lake Chuali and Massingir Dam, and in Botswana fieldwork in Lake Ngami was undertaken.
? One Egyptian Goose captured in South Africa tested positive for low pathogenic H1N8.
? 224 hours of observations have been conducted.
? 2255 blood samples have been collected (two per bird); 2655 cloacal samples (two per bird); 1468 feather samples; and 2655 tracheal samples (two per bird).
? 72 different species have been sampled; 18 of those have been captured 10 or more times. Most common captures are the two ducks the team identified as the highest risk species, red-billed teal and Egyptian geese. In the upcoming Austral summer bird numbers and captures (particularly of palearctic migrants and molting ducks) will likely increase.
? During the next quarter, 44 GPS satellite transmitters will be attached to birds at Strandfontein, Barberspan, and Manyame, and Dr. Cumming will work with Zimbabwean collaborators to attach them to red-billed teal and Egyptian geese.

Training and outreach:
? 40 people have been trained in capture, handling, and swabbing techniques; two coursework MSc students have successfully completed related projects and are submitting work to an academic journal; and Mr. Mduduzi Ndlovu is mid-way through a two year thesis MSc.
? An SA-GAINS paper on risk analysis for avian influenza in southern Africa is under review in the peer-reviewed journal Ecology and Society as part of a special feature on risk mapping to be edited by Dr. Cumming.
? Dr. Jon McCloskey has joined the team to contribute to the remote sensing component of the project, and Mr. Gregory Mutumi will begin work on a MSc thesis on stable isotope mapping, using the feather samples collected through GAINS.
? Dr. Michael Kock, WCS field veterinarian, met with the International Conservation Caucus Foundation (ICCF) led by the ICCF President, David Barron in Cape Town in December. The ICCF brings international conservation issues to the attention of US leaders and educates and assists them in addressing conservation challenges worldwide. Dr. Kock met the delegation over lunch in Simonstown and his presentation included an update on GAINS.

Here's a step toward more accurate testing:
University of Georgia. GAINS has signed a contract with Dr. David Stallknecht and Dr. Justin Brown of the University of Georgia to jointly test wild bird serum samples for H5N1 antibodies. Despite ongoing analysis around the world, there are no avian influenza serum tests that are validated for use in wild birds. However IDEXX has recently created a new ELISA test that is expected to be highly sensitive in wild birds. This test is not currently commercially available. IDEXX has donated hundreds of testing kits to the University of Georgia for the testing of GAINS wild bird samples from around the globe. The goal of this testing will be to help identify wild bird species that may be carriers (individuals that intermittently shed virus but do not show signs of illness) or previously exposed to H5N1, and to assist in validation of a serum test for wild birds.

It's not my intent to rehash the whole issue; I'll keep your advice in mind for future discussions.
 
Re: How to Think Analytically

Re: How to Think Analytically

I made a quick post a few days ago in response to Florida1's request to amend my writing, I think that she deserves more than that. You all do.
==================================
My intent vs my effect:
My intent was, and is, to share an example of "critical thinking" so that people who are not taking effective action (no-one in particular, just 'at-large' for all the readers, since I assume the FT members are "in the choir") due to indecision, can learn the tools to find the answers they need. See http://en.wikipedia.org/wiki/Critical_thinking for a concise overview of what 'critical thinking' is. Snip....and across subject fields in all those spaces where human beings need to interact and make decisions, solve problems, and figure out what to believe and what to do...snip.
I will again quote wikipedia; snip..... Critical thinking is useful only in those situations where ......snip...That is, just about everywhere and all the time.....snip.
Wikipedia also quotes Dr. Martin Luther King: "The function of education, therefore, is to teach one to think intensively and to think critically . . . The complete education gives one not only power of concentration but worthy objectives upon which to concentrate."
Since reducing morbidity and mortality is a 'worthy objective', I was thinking intensively, but to the exclusion of certain sensitivities. Therefore.....
My effect has been something other than my intent, and I am responsible for fixing that. I edited my posts, but think there is more that I should do. My first posts were about 'critical thinking'. This post will be about being 'critical'. I am going to be critical of my first posts here, for falling short of Flutracker's higher standards. I am finding that, the very essence of what attracted me to this forum, is easier to observe than it is to duplicate. Therefore I will adopt, as a 'worthy objective', to stand outside myself and see what I have written through other people's eyes.
1) I should have recognized that my string of posts would constitute a thread hijack, and I should have started a new thread, and linked to the previous thread "The power of negative thinking...(H5N1 in Pakistan)". Thanks Florida1 for doing both of those things for me.
2) In the following post, I will detail what I found out as I tracked down the source of the Daily Times article.
3) I believe that activism is an important component in the 'checks and balances' of our political world. In my critique, I did not adequately separate their organization(s) from the behavior of perhaps as few as one individual. I pledge to do better. I will focus on the content, and resist the language of negative generalizations.
4) Since I sometimes include more detail than some folks want, I will try to insert headings such as; SUMMARY, or ANALYSIS, or BOTTOM LINE.... so people can skim if they want, and then dig deeper if they are interested.

Please understand, that I like birds. I maintain several birdhouses on my property, and enjoy them greatly. I agree with; "WWF's ultimate goal to build a future where people live in harmony with nature". I am borderline compulsive at 'reduce, reuse, recycle', and bicycle almost as often as I drive. I harbor no malice toward any of the above organizations, indeed my biases are in favor of their agendas. I understand that my preceding statement is meaningless, if the reader gets an impression other than what was in my head. My bad.
 
Re: How to Think Analytically

Re: How to Think Analytically

ANALYSIS: of who is behind the article that was published in the Daily Times in Islamabad.....
In the post about the WWF (http://www.wwfpak.org/150208_avian_influenza.php , dated 15th Feb. 2008. ), it was not sufficient for me to say "They are entitled to their opinions and their perspective", for at least two reasons. It was neutral, not positive. Even if it were positive, is doesn't balance-out either the quantity or tone of the other (negative) stuff I said. I think that what happened is that I was angry with the mis-information in their press release, and it spilled-over into the tone of my summary of 'organizations with visible agendas'. Transference perhaps? Not acceptable for sure. I will give WWF the benefit of the doubt, and would even propose that the WWF branch in Lahore may have made a rogue statement that doesn't reflect the position of the larger organization. If that press release was a rogue action, then I hope the parent organization quickly rectifies the situation. They have just as much responsibility to stick to the truth as everyone else.
Curious to see whether the parent organization supports the view from Pakistan, I went to their main website,WWF.org, and spent over a half hour clicking through most of their U.S. website at http://www.worldwildlife.org/ and didn't see anything similar to the content in the "Daily Times" from Islamabad. A 'site-search' using the term <bird flu=""> turned up a far more reasonably-worded document saying..... "Experts do not have a clear picture of the role that migratory birds play in the spread of this particular strain of avian flu but it is possible that ducks, geese and wading birds could spread HN51 along migratory routes". Also, the basis for their concern can be seen from the following.... "World Wildlife Fund does not believe that culling wild birds is an effective control measure to stop the spread of avian flu. Culls of wild birds are unlikely to stop the spread of avian flu and culling could actually make the situation worse by dispersing infected individuals and stressing healthy birds, making them more prone to disease," said John Morrison, deputy director of WWF's conservation science program. "The focus for now should be on monitoring domestic poultry, minimizing the movement of domestic poultry and keeping contact between domestic poultry and wild bird populations to an absolute minimum." I am concerned that this 'only document on the topic' was dated 11/03/2005. Nothing newer?
WWF.org provides links to 48 websites, one for each of their branches around the globe. So, I then went to the 'WWF Pakistan' and 'WWF India' (for good measure, and since both Lahore and Islamabad are so close to northern India) locale-specific websites, and did a "site-search"using <h5n1> and <bird flu="">as search terms. Only the Pakistan site had 'role of wild birds' documents, there were two of them. One of the two was obviously the source 'press release' that the Daily Times had used. The title "WWF Pakistan’s statement on the role of wild birds in the spread of Avian Influenza outbreaks in Pakistan", makes it sound like it got management approval. Nowhere did it say anything similiar to..... "the view(s) expressed here are the author's only and do not represent the views of the WWF". Which makes it difficult to ascribe the statements to "rogue action", unless the Pakistan operation is only a one-man-show (write it, approve it, and post it..).
Are the statements simply mis-informed? Not likely. Out of all of the numerous sources of information available, the "press release/statement" lists four. The probability that anyone could look in only four places at random, and see only these four references is so small as to be absurd. Therefore we have to assume that the author saw information supporting the opposing argument, and selected against including it. That is called biased, or slanted, or skewed, not objective conclusions. The WWF author even referred to his own bias by saying that he "would like to highlight some of the scientific facts that support the case ". Let me be clear, If this content was included in an internal memo, or in a print-only publication to their members only, then I have no objection. A press release (and web article) that lists 4 biased pseudo-facts, and then states "In conclusion it is unlikely that wild birds play a major role in spreading avian influenza", is irresponsible. The Daily Times in Islamabad, even without the benefit of a scientist to review the content, could have seen the obvious deficiencies, and carried it as an opinion piece, if it all., not paraphrased it in a 'reporting-the-news' style.

Let's look at the four references listed in the WWF on-line copy of the 'press release'.
1) The BirdLife.org site lists an FAO article titled "FAO says human activities, not wild birds, spread H5N1" dated May 22, 2006. http://www.birdlife.org/news/news/2006/05/avian_flu.html I can see where BirdLife got some of their material, however, elsewhere in that same article we find... "It is indeed likely that (wild birds) can introduce the disease to unaffected areas from countries in which the disease has already been identified, the FAO’s statement asserts", .....snip, which indicates that the WWF author took the supporting text out of context (emphasis mine) from Birdlife's 5 paragraph condensation of a 9 paragraph FAO document. If you look at the original FAO article, there is mention of "insufficient resources have been allocated to be able to study the question properly." So, the FAO, who deals with domestic animals, not wild birds, was trying to raise some funding. Their focus was on the poultry side of the issue,but not to the point of being misleading. Most of the rest of the WWF-Pakistan piece looks like it came from an separate article titled "BirdLife Statement on Avian Influenza" dated August 2007. Of the four references, I found the highest amount of bias at Birdlife.org.
2) http://www.aiweb.info/ in an article titled "What is the Role of Wild Birds in the Spread of HPAI H5N1?" included a most insightful passage.... "The loss of wetlands around the globe may force many wild birds onto alternative sites like farm ponds and paddy fields, bringing them into direct contact with chickens, ducks, geese, and other domestic fowl. " The message I get is that the animals on this planet are competing for the food resources. Much to their credit, aiweb included, "analysis or genetic sequences and other indirect evidence suggest that in at least some cases wild migratory birds are likely to have contributed to further spread." You can also find "Risk of Misinformation and Adverse Policies" at http://www.aiweb.info/document.aspx?DocID=296 Aiweb seems to be reasonably diligent, and fair, only slightly biased.
3) http://www.who.int/mediacentre/factsheets/avian_influenza/en/ This webpage contains thoughtfully worded and carefully parsed statements, which collectively provide a cohesive picture of what is broadly accepted as fact. Any biases present are neither for nor against either domestic poultry or wild birds, and covers the roles of each in the current situation. If you want to be 'informed' about avian influenza, and not propagandized, go here and read the whole thing, not just parts. I highly recommend it. Kudos to the WHO. It is highly ironic, that this reference includes the following passage...."Further spread of the virus along the migratory routes of wild waterfowl is, however, anticipated. Moreover, bird migration is a recurring event. Countries that lie along the flight pathways of birds migrating from central Asia may face a persistent risk of introduction or re-introduction of the virus to domestic poultry flocks.", which refutes the WWF 'position statement'....."of an infected bird capable of migration therefore migratory birds cannot be held responsible." Note also, that the WHO information is dated Feb. 2006. It it were re-written today, it might dispel much of this debate. If it were updated, (especially in 'The Disease in Humans' section) hopefully they would recognize recombination along with their survey of a) reassortment and b) adaptive mutation. It does not escape my notice that they referred to method b) as adaptive mutation, not 'point mutations', or 'drift', thus leaving the door open to listing recombination as a subset of adaptive mutation. The WHO could also stand to update their "WHO Handbook for Journalists: Influenza Pandemic" Last updated December 2005 Even that document says "In September 2005, H5N1 was detected in domestic and wild birds in Russia and Kazakhstan and in wild birds in Mongolia." which severely refutes the wwfpak.org claim of "no fully documented healthy migratory wild birds have tested positive for H5N1". (note: the source for the above wwfpak claim can be found in the next reference, and is based on testing from 2003 and 2004. Shouldn't journalism that purports to be factual , as current information, but doesn't declare the data to be 4-5 years old, be chastised? I think that wwfpak.org and Daily Times in Islamabad, should at least be ashamed.
4) http://www.fao.org/docs/eims/upload/191072/EW_HPAIwildbird_aug05.pdf The FAO's EMergencyPREvention Systems (EMPRES Watch) published a .pdf in Aug. 2005 (ages ago, in terms of viral evolution), covering "Potential risk of Highly Pathogenic Avian Influenza (HPAI) spreading through wild waterbird migration - Updated version". Why on earth would the WWF-Pakistan author have put this in the reference list? He shot himself in the foot here, perhaps trying to make his conclusions look reputable, and hoping that nobody would actually look at the references. This document is also old (2.5 years). Even so it talks extensively about wild birds as both reservoir and transmission mechanism.. It details the early migratory spread northwest from Qinghai lake into Mongolia and Kazakhstan, and the flyways southwest over the Caspian Sea, Black Sea, and on into Africa, which is what we have seen happen each year.
It is beyond irresponsible for the Islamabad Daily Times, to publish as news, a WWF-Pakistan 'biased' press release based on a Birdlife.org excerpt, from an FAO 'fund-raiser' article from 21 months ago. The other three references are somewhere between 'even weaker' and 'downright contradictory'. Conclusions and claims the size they are making should be based on peer-reviewed journals, or scholarly reports that are at least recent. Even if I were a member of these wildlife conservation organizations, I would take exception to, and be critical of, such blatantly slanted statements.
Applying 'critical thinking' can show that some information sources are better than others, and in general it is helpful to know what that source's motivations are to account for the possible biases. Also, checking references helps, so that decisions don't get made on inappropriate data. There is a danger in getting mired in too much detail, and never taking action. It's like arguing "which came first, the chicken or the egg". Bad pun huh? You don't need that answer, to either; make chicken soup, or to fry some eggs. The opposite danger is to fly blind without slowing down occasionally to get re-grounded. So periodically getting analytical with your 'trusted sources' can add confidence to decision-making.
BOTTOM LINE:

There is a bigger picture here. It is more important to know what is possible than what has-been. I think everyone can agree now that both wild birds and the domestic poultry trade can spread the disease. So can people themselves. Let's work together instead of bickering, we might just need each other to beat this H5N1 problem. A first step in working together is to "drop the weapons" and replace the mis-information, and skewed rhetoric with facts and alliances.

It is not enough to simply observe the problem, I propose to find solutions. Perhaps the sensible thing to do is to contact the WWF central group, and enquire whether they are aware that the folks in Lahore have posted this biased information, and released it to the media. I propose contacting the WWF and requesting that they remove the offensive article from the web, and issue a more centric press release via the Daily Times. I volunteer to contact them, unless someone else at FT would be more appropriate, and would like to do so.</bird></h5n1></bird>

Re: How to Think Analytically

Re: How to Think Analytically

In response to JJackson's post, having just spent a big chunk of time on several of the 'avian conservation' websites, I will summarize what I have read. It necessitates some generalization, so bear with me.
1) Their on-going concern is loss of avian species (threatened & extinction) and loss of population size.
2) Birds need specific conditions to thrive such as; breeding grounds, food supply, freedom from disease.
3) Conservation focus is on preserving critical habitat such as wetlands, breeding grounds, and open space.
4) H5N1 may have mutated from LPAI to HPAI in the wild, or on 'factory farms', but the effect is the same. It exists.
5) The wild bird's perspective is that the disease (HPAI H5N1) is endemic in poultry, in several countries.
6) The poultry's perspective is that wild birds carry and transmit HPAI H5N1 and are a global threat.
7) The human perspective is that H5N1 is endemic in both wild and farmed birds, and both are threats. ;-)
8) Because the disease can transmit easily from wild-to-domestic and back again, both serve as reservoirs to the other now.
=============================
9) Conservation groups are not denying that wild birds are ill, but instead assert they are getting infected from poultry.
10) They don't want wild birds to be 'controlled and contained', they want less human (and poultry) encroachment.
11) Yes, they do want wild birds separated from poultry, by keeping the poultry contained, and controlled.
12) Both poultry farmers and wild bird protectors want the same thing, eradication of the disease.
=============================
13) In many countries implementing biosecurity is somewhere between difficult and impossible.
14) Humans have more control over poultry than wild birds, so they have been culling poultry in huge numbers.
15) HPAI decimation of poultry flocks, directly or via culls, is a huge loss to humans, both in food and money.
16) If repeated culls and restrictions of poultry trade don't solve the problem, humans may take steps against wild birds.

Specifically, and I read this on their websites, so this is not speculation, they are worried about.....
a) draining of wetlands .
b) shooting and other methods of killing wild birds .
c) scaring birds away from their preferred living spaces.
d) deliberate destruction of nests and nesting lands .
e) human population expansion forcing wild birds into closer contact with domestic poultry(and infection).
f) wild lands converted to argiculture for both foods and fuel-crops.

O.K. now I would like to editorialize for a moment (my thoughts).
I think that if conservation groups want to help the wild birds, they should stop with the denials of 'how it is spread'. That's just a bunch of 'hissy-fit' finger pointing, and it doesn't solve anything. Also, if this disease jumps to the human population with easy H2H2H, I would expect retaliation against wild birds to meet or exceed poultry culls. Emphasis should be on finding ways to stop this disease now.
I've read a technical paper by ornithologists that suggests the current surveillance is deficient by using ambiguous names for the birds that are tested. Do the virologists agree that specific I.D. would help? If so, perhaps the wild bird advocates would fund a BSL-3 lab that does identification work on dead birds. Or maybe they are already providing assistance in bird I.D. to the swab-collection teams (a color picture 'guide' book or field classes).
One approach might be to initiate more control and containment of wild birds. They should start now at building an avian "Noah's Ark" till this thing blows over. Then they can 'try' to vaccinate the birds in their care, a task almost as large as vaccinating all of the domestic poultry in the world.
In regard to government funding, I think the conservation groups are best to ask 'what they can do for their government(s), not what their government(s) can do for them' to paraphrase a famous quote from John F. Kennedy.

Thank you - an excellent analysis, that places reporting on the issue of wild bird infections and spread in a more understandable context

I would propose that learning "how [HPAI H5N1] is spread" is one of the most important parts to efficiently utilizing resources to combat its spread.

If we are to understand (in a predictive sense) how HPAI H5N1 moves through the environment, then, yes, I think that specific IDs would be very helpful. How do you know where a bird came from, where it's going, how long it may have been there, what kinds of habitats it is likely to frequent, etc., without a proper name? Having the proper age/sex/ID of a bird can tell you a great deal about the phenology of the movement of the individual or the populations, and gives a much greater capacity to predict what that effect might be on the system (whether that system is humans, poultry, or wild birds).
 
Re: Power of Negative Thinking (H5N1 in Pakistan)

Re: Power of Negative Thinking (H5N1 in Pakistan)

About 'negative' data: Let's say that you have a page of data. It's mostly filled with zeros, with a few Xs sprinkled about. The WWF is hoping that you will ascribe equal importance to both zeros and Xs. What Dr. Niman points out is that there is a huge difference. There are many ways that a test can return a zero, called 'negative' data....

When Dr. Niman calls it "negative thinking", I think he means "thinking based on 'negative' data", which is to say, conclusions based on a page of data that's mostly zeros. Of course he takes issue with this because the empirical data, the Xs, are the true milestones that describe the path of interest, not some fog-banked empty fields to either side.

I think that you may be missing the point of data: the relative importance of zeroes and x's are equal in the realm of data collection. The point that you're trying to make (i think) has to do with interpretation of the data.

In this case you make the argument that Dr. Niman has demonstrated that the assays used by most governments and monitoring agencies are not suitable for detecting the virus. If this were the case, you would apply that understanding to the data that has been collected (e.g., if the false negative rate of a test can be measured, you can then apply that rate to the number of negatives that you measured in your data and come up with a better estimate than by using the test alone) and discuss that in the body of a report.

Yet, one thing that I haven't seen in the scientific literature is an analysis of the testing methods being performed (I haven't been around in a while, so something may have come up, so if I'm wrong I'd love to get the citation!). Without good objective research into testing methods we are left with people's opinions of testing methods--which may or may not be accurate--and are no better off than conjecture. No one talks about it in their discussions as a means to temper their findings, no one seems to be publishing much about the testing efficacy, and it seems like every month or two another study is published by a large monitoring effort.

So-I wonder if the testing of the tests is lagging behind their use, or can someone point me to some primary lit that discusses their efficacy?

Re: How to Think Analytically

I just saw this article; maybe it is another step in the right direction. I don't know if the study has been posted here yet. Edited to add: Canagica posted it here :http://www.flutrackers.com/forum/showthread.php?t=56430

Some Countries May Have Slowed Bird Flu's Spread
WEDNESDAY, Feb. 27 (HealthDay News) -- Several strains of H5N1 bird flu virus that afflicted southern China were blocked from entering neighboring Thailand and Vietnam, say University of California, Irvine, researchers who conducted the first-ever statistical analysis of H5N1's genetic diversity.

The study was published online Feb. 27 in the journalPLoS One.

He and colleague Walter M. Fitch, professor of ecology and evolutionary biology, analyzed almost 500 publicly available genetic sequences of proteins found on the surface of H5N1 samples collected from 28 locations in Africa, Asia and Europe.

They found that H5N1 strains in Indonesia, Japan, Thailand and Vietnam shared the most evolutionary history with H5N1 found in three southern Chinese provinces -- Guangdong, Fujian and Hong Kong -- that are engaged in intensive international trade, including poultry.

Previous research has identified poultry trade as the key factor in the spread of H5N1.

In last night's posts, I tried to use the WYSIWYG editor instead of the 'standard' editor'. It didn't seem to recognize the URLs as links, even though I had checked the box for "automatically parse links...". A work-a-round is to copy and paste the URL ( HTTP://..... ) into your browser. Sorry for the inconvenience, I'll try to figure out what I did wrong. :oops:
