If they brought it up, they might not be employed as researchers for long. So your heuristic will end up selecting for cranks.

Better a crank scientist than a stable religious official. Because that's what it's called when there are possibilities you are not allowed to examine.

Are you aware of any research supporting genetic inheritance of intelligence. The psychologists I know have told me that there is very little evidence to support that.

See:

* https://en.wikipedia.org/wiki/Heritability_of_IQ

* https://onlinelibrary.wiley.com/doi/abs/10.1002/neu.10160

From that wiki article:

Twin studies of adult individuals have found a heritability of IQ between 57% and 73% with the most recent studies showing heritability for IQ as high as 80%. IQ goes from being weakly correlated with genetics for children, to being strongly correlated with genetics for late teens and adults. The heritability of IQ increases with age and reaches an asymptote at 18–20 years of age and continues at that level well into adulthood.

> The authors acknowledge that an enriched social, educational, economic and intellectual environment can and does raise intelligence scores, but they insist that even when due allowance is made in terms of statistical comparisons of all other factors and measuring their relative weights, intelligence still seems to be strongly influenced by the genes of one's forebears.

There is quite a bit of evidence suggesting genetic inheritability of intelligence. For a very simple example, we have twin studies that show a greater correlation in the intelligence of identical twins than fraternal twins. (The correlations of identical twins still aren't 100%, though - intelligence seems to include a random or "non-shared environment" component) Here's Wikipedia's take: https://en.wikipedia.org/wiki/Heritability_of_IQ

You don't think that smart people are more likely to have smart children? Do you think that tall people tend to have tall children?

Why didn't you say so! I mean, if your psychologists said so then it must be

The alternative hypothesis is completely stupid. Chimps and humans have different intelligence. Are you saying that this isn't genetic?
