I think we are ignoring that the statistical aspect of our ability to reason effectively and to apply logic was predicated on the deaths of millions of our ancestors. When they made the wrong decision, they likely didn't reproduce. When they made the right decision, that particular configuration of their cortical substrate was carried forward a generation. The product of this cross-generational training could have easily led to non-intelligence, and often does, but we have survivor's bias in our favor.
