Declaration of Helsinki

"Bush's FDA has just announced that it is going to scrap American participation in the Declaration of Helsinki -- the major international accord on ethical principles guiding physicians and other participants in medical research on human subjects. This isn't a decision involving mere medical bureaucracy -- it in fact clears the way for ethics-free drug testing, especially beyond American borders, and it means people will die, sometimes horribly."

Texas State Board of Education Chairman Ron McLeroy

WHY DOESN'T HE QUIT!?!?!?! Yes, its genuine embarrassment I feel that this tool is the CHAIRMAN OF THE TEXAS BOARD OF EDUCATION. Parents hear this: He gets to make decisions on your children's education curriculum. Well just read his the transcripts of his speech to xxxxx church, or listen to it (its better to read then listen).

Busy now will update with the links.

A Repetitive Voice Can Sound Like a Chorus

I think this study sheds light into why so many of us believe in all kinds of unbelievable/unproven stuff. From Saddam working with the 9/11 terrorists, to supernatural beings who spend their whole day keeping an eye on our behavior.
In a nutshell it makes the point that humans will confuse the repetition of an idea, no matter its basis in reality, as a widely held belief which gives it credence. Even if the repetition comes from only one source. Now that is pretty powerful if you think about it. Read the study here:
The present studies test these hypotheses and provide the first evidence that repetition of the same opinion gives rise to the impression that the opinion is widely shared, even if all the repetitions come from the same single communicator.

On Vaccines...

I have been wondering about shots. I was kind of freaked out when I learned about parents actually not vaccinating their kids for fear of autism. I don't know what to believe, but I do know this should be a pretty run of the mill problem for good science and honest research. I would expect that a pretty definitive conclusion could be made regarding any link to vaccines that autism may have.

Shot records have to be some of the most abundant records, surely enough to provide huge amounts data. Now make sure that you account for the changing criteria used to diagnose autism through the period being studied(my gut tells me this is the herring). Oh, don't forget to thoroughly discount all the other things that could be producing higher autism rates. Is there higher autism rates or higher rates of diagnosis?

Now its not that I don't believe there may be a link, and some people I respect say there is. One is Robert F. Kennedy Jr., and others include the parents of children with autism. But I just cant shake the thought that parents are actually not immunizing their kids. It seems, I hate saying this... selfish. I guess what bothers me is the risk to the children who may not get the vaccine protection. I'd bet (if I had to) that this is probably worse than the possible risk of autism. Not just that but what about the rest of the population that is put at risk by non-vaccinated-Americans.

So then somebody else I respect, Michael Shermer, comes in with a great article from his Skeptic Magazine. As I had thought the Vaccine-Autism link may be a mirage that sadly plays on the fears of parents who may be blindsided by love and anguish over their children. The piece by Kennedy linked above is discussed on the Skeptic piece and I recommend reading both for all the angles that play on such a touchy subject.

Mercury Rising / Exposing the Vaccine-Autism Myth by Matthew P. Normand and Jesse Dallery

In this article we shall make five points concerning the relationship
between thimerosal-containing vaccines and autism.
1. The dangers of mercury are well established, but this does not lead inexorably to a relationship between thimerosal-containing vaccines and autism.
2. A number of well controlled studies have failed to uncover any correlation between the delivery of the vaccines and the onset of autism.
3. Even if some correlation existed there are a number of possible explanations for the correlation that do not assume any causal relationship between the vaccine and autism.
4. Much attention has been given to a possible government cover up, which is certainly
of concern if true but is otherwise independent of the problems with the claims
of a link between thimerosal and autism.
5. The type of public hysteria manifested in the current controversy is not new and we would be well served to learn from similar controversies of recent times.


To make a short story long, I'll end with a bit of Shermers introduction to the story that kind of nails it for me:

Remember always that we are pattern-seeking primates who are especially adept at finding patterns with emotional meaning — in this case, the parents of autistic children are understandably seeking a causal link that provides them with an opportunity to right a wrong, in this case fixing the problem through changing the body’s chemistry, diet, nutrition, toxin load, etc. Sadly, it appears at this point that the causal vector(s) probably lie elsewhere.— Michael Shermer

This is cool. Read the heresy, or even better listen to the complete texts on your MP3.
