Ha ha, love this. Ofcourse what we might call "higher" brain functionality is not uniformly distributed as realized capabilities, being a obscure mix of innate hardwiring and education. But it would be extremely odd if it wasn't quite uniformly available to all fully functioning brains in a qualitative and in-principle manner. Which begs the question: why would individuals intentionally diminish the own status when there is nothing much objective to support it? I guess it is for them to answer this, but what I would volunteer as a possibility is the enormous power of collective mental models / narratives. By adopting the "brain is a computer" narrative you become member (or aspired to become) of a certain social group that, incidentally, has been "winning" in a certain socio-economic context.
