I guess I shouldn't have assumed everyone thought like me. :) Is it more sensitive than intelligence in general, or just IQ? Would you react more strongly to being called "shrimp" than "stupid"?

I don't care about names. But looking down instead of up makes quite a big difference.

I don't really believe in IQ as anything more than a statistical artefact in the first place. But of course, different people are going to perform differently on different tasks.
