So apparently the folks over at Noetic Sciences have decided to answer or officially address the standing question of whether psychic abilities are hereditary and more so if there's a specific gene associated with psychic phenomenon. Below is a link to the case study in question:
Needless to say, the results from this case study are very inconclusive, which of course is to be expected given the rather elusive nature of genuine psychokinetic or even psychic phenomenon.
Interesting enough, according to the case study finding non-psychic controls i.e. women (not sure why the control group seems limited to just one sex) with no claims of psychic ability in themselves or their family members proved to be more challenging than expected.
"Due to the studys exploratory nature, no selection was attempted for specific types of claimed psychic abilities. It seems unlikely that the same genetic component or networks generate all psychic abilities, so our small samples heterogeneity may have precluded the observation of more robust genetic differences. Future studies could include comparisons between specific types of psychic abilities."
