Braineclipse. Thank you for responding directly to me. You make some interesting points.
You say I have been tricked by anti-vaxxers who are only in for the money. Can you point me in the direction of any person or organisation who is making money out of anti-vaccination? I have never met anyone. In fact many people suffer considerable financial loss to tell their story. Many have rejected the non disclosure agreements so they can speak out.
You deny that autism has increased on the ground and any reported increase is down to a change in the way Autism is reported. That is not my experience.I find it surprising that science does not have the wherewithal to take this into account when publishing figures.
You offer the explanation that organic food is the cause of autism. You need to will give a simple explanation for a lay person so I can understand this. It is slightly more plausible than other explanations offered on here such as not loving your kids enough and wearing the wrong shoes.
I acknowledge that Wakefield did make the hypotheses that vaccines damaged the gut and that triggered disturbances in the immune system which in turn caused autism. Where does organic food fit in?
And thank you for staying on topic. To be clear I wouldn't mind discussing other topics, but I prefer doing these one at the time.
On money:
How about Andrew Wakefield as an example? He had several undisclosed financial interests that he would profit from had his initial paper on autism and vaccines been confirmed or at least remained debatable. He's given numerous talks, published a book and now helped produce a movie. Having been discredited by mainstream science and medicine this seems like a good source of income for him.
Other examples include those pushing supplements and nutrition advice along with their anti-vaccine message. Often all as an alternative to vaccination. Or how about the many alternative medicine "cures" for autism allegedly caused by vaccines. Including those promoted by Jenny McCarthy. In short the alternative medicine industry along with the supplement and nutrition industry are big money makers both for countless individuals and for larger corporations. The anti-vaccine message is often included in their overall message and I believe it to an important scare tactic for them. Your kid is more likely to get autism unless you follow our advice is a pretty convincing marketing strategy aimed at parents.
Of course most people in just about any movement will not be profiting from that movement. Just like the vast majority of people who believe the mainstream scientific view (here and elsewhere) do not earn a single penny from defending the science based view on this topic.
On the diagnostic category changes:
There has been a change in how autism is diagnosed. This is a simple fact. If people are claiming to inform you on autism and the increase in the number of diagnosis without including this very basic information that would be a big red flag for me. This is readily available information. Had a quick google and this page seems to highlight the running changes quite well:
http://bdkmsw.umwblogs.org/what-is-autism/autism-in-the-dsm/
These changes are not surprising. New research and a growing understanding of the phenomenon along with clinical experience has developed and changed the understanding of how autism should be diagnosed. Remember we're working from a point where pre-1980 the diagnostic manual didn't even differentiate autism from schizophrenia. The clinical changes in the last 40 years have been huge on this topic.
Again, this is only one factor. When autism was first included in 1980 most likely a lot of clinicians would not have been up to date with the research and would have taken time to get to know this "new" diagnosis. Clinicians educated since then would have gotten this as a part of their education, along with better screening and better access to health care this goes at least some way towards explaining the increased number of people being given the diagnosis. The article I first linked explain these things quite well and it's based on what seems to be a solid research paper.
I deny that the actual autism numbers are rising in the population based on findings such as these and an understanding of how diagnostic manuals are being used and how diagnosis are being made. I'm not sure I understand your objection. If you could expand a bit on what you mean I would be happy to discuss it.
On correlations:
You misunderstand me and I can only assume you didn't read the article I first linked to. I'm not saying that organic food is causing autism. I'm saying that the correlation between the growth of organic food sales and autism is very similar to the correlation between the growth in vaccination and autism. (And one would assume the correlation between vaccinations and organic food sales). The point is that these kinds of correlations do not prove causation. Correlations can indicate causation, but no conclusions can be made based on correlation alone. I no more claimed that organic food causes autism than I claimed that vaccinations are causing an increase in the sale of organic food products.
Based on these correlations alone it would be equally invalid to conclude that autism was caused by organic food as it is to think it's caused by vaccines. That's my point.
This misunderstanding is a fairly common one. I mentioned before that I think you're being tricked and I believe one of the ways you're being tricked is by the use of correlations to "prove" what they cannot prove. I really would suggest reading up a bit on what correlations are and what they show, it makes one less receptive to people misrepresenting facts.
