The antiinnatia theory of autism was published in 1993 in the peer-reviewed PsycInfo-indexed journal <i>Personality and Individual Differences</i>. It remains completely unchallenged and unfaulted and unrivalled and now numerous of its remarkable predictions have been confirmed. Not least it explained <i>why</i> the same factors that cause high IQ (and creative genius) would also increase autistic tendencies, and vice-versa. You can see this made clear in the opening of the paper's abstract:

"Summary--This is the first part of a combined theory of autism and general intelligence (IQ). It is argued that general impairment of gene-expression, produced by a diversity of environmental and genetic causes, is in moderation advantageous in reducing genetic idiosyncracies. But in extreme it will produce a condition involving atypicalities of appearance and behaviour, with a particular relationship to high parental social class and IQ and with particular sex distributions...." [In the updated presentation “general impairment” has been changed to the less-confusing "evolution-biased reduction”.]

At the time of publication, no-one was talking about gene-expression in autism. Now just about everyone is.

The key concept, "antiinnatia", may be roughly summarised as "evolution-biased reduction of gene-expression", though originally as "general impairment of gene-expression", but it can only be properly understood by reading the paper, preferably in its (unrevised) updated presentation at https://www.researchgate....

In its original form, as sent to journals in 1983, the theory also extended to an explanation of creative genius, as resulting from a critical intermediate level of antiinnatia, suppressing only intellectually-prejudicing tendencies such as conformity, self-conformity, wishful-thinking, and presentmindedness. That section on genius was only removed due to the considerable hostility to that concept in certain sectors of society, which was feared to be inhibiting publication.

Among the various remarkable confirmed predictions, there has been the prediction and confirmation that mercury pollution has caused the huge Flynn effect increase of average IQs, in stark contrast to the universal assumption that mercury was causing lower IQs:

Since the publication of the antiinnatia theory, a great many researchers have been re-inventing wheels already fully developed in the antiinnatia perspective. And worse, a whole culture of pseudo-scientific misunderstanding about a mythical "disorder" or "disorders" when in reality autism is simply an aspect of human variation with not the slightest real evidence of any necessary pathological aspect.

The time is long overdue for others involved in autism research to have regard to the now resoundingly confirmed antiinnatia theory of autism and start building on its insights and citing it in their own publications.
