The prevalence of autism is 1 in 42 for boys and 1 in 189 for girls. In 1966, researchers estimated that about 1 in 2,500 children had autism. How do explain this drastic change in the numbers? An article in Scientific American explores the question. Read here.
Note that this article does not mention vaccines which is a little strange given that many have argued that they do and many studies have been conducted to investigate whether there is any connection. Even if the consensus is that there is no connection, you'd think the article would mention that the question has been raised. Are free thought and speech allowed on this topic? Are the authors afraid of ridicule, slander, and abuse? Reminds one of the topic of Zionism where free thought and speech are not permitted in the media, political forums, and in many homes.
