Why? Because the mean IQ at the top of the bell curve is 100, meaning a whole lot of people fall on the under 100 side of the bell. With some 7 billion people on the planet, that means maybe 3 billion have IQs under 100. Worth keeping in mind as we go through our daily lives.
I know there are a lot of low IQ people out there, but there were enough posting that they thought this did not really happen that it now seems like talking point trolls. I am amazed but I guess I shouldn’t be.
Ability to arrive at justified true belief is not directly measured by IQ testing.
Consistent with this is the fact that many high IQ individuals believe ideas like man-made global warming, and that the theory of evolution has been proven through scientific observation and replication.
