I’d guess that the person of median-intelligence now is intellectually inferior to the median European cave dweller of tens of thousands of years ago. My rationale for this is that stupid people have it a lot easier these days. There are all sorts of social safety nets in place keeping the dim and dull alive and reproducing and voting Democrat. Back in the day, folks had to get by on their wits, and if you weren’t very bright, your chances of surviving were diminished.
Based on my opinion of the average Democrat, you make sense. How can they be so easily fooled by those who give them shiny promises but in action are so obviously corrupt? They are there just to acquire money and power, but their brainwashed followers are so hypnotized by their TV’s that they can’t see it. Baffles me.
