V.kemp>There are many types of intelligence. Having absurd beliefs (believing the impossible, highly improbably, etc) is a sign that certain types are lacking. This is a stupid discussion of the obvious.

Justinian>It isn't obvious to me. I fail to see how having absurd beliefs is a result of lacking a type(s) of intelligence. Rather it's a result of having biases, which has nothing to do with one's intelligence

v.kemp>You don't think a person believing in something they know to be impossible is any indicator of intelligence? Holding irrational beliefs is the definition of irrational. Irrational and intelligence are not a common pair.

Irrational is pretty relative. I find the concept of space-time expansion creating the universe pretty irrational. That's a debate for another topic though. My point is that everyone's concept of irrational varies and is therefore not a good indicator of judging intelligence. In practice judging intelligence like this leads all individuals to view everyone else with differing opinions as stupid idiots. Based on their concepts of irrational they would always be right in their minds.

Now taking this idea back on topic, You can't call a racist stupid because they believe in ideas that you would call irrational. They would say your beliefs are stupid since you don't believe in the superiority of one subspecies over another.
