Haven't had one of these for awhile. This thread is for questions or comments that you've felt silly about not knowing/understanding. Let's try to exchange info that seems obvious, knowing that due to the illusion of transparency it really isn't so obvious!
What are your best arguments against the reality/validity/usefulness of IQ?
Improbable or unorthodox claims are welcome; appeals that would limit testing or research even if IQ's validity is established are not.
What does arguments against "reality" mean?
Arguing against misconceptions of what people believe about IQ? In general I consider arguments against reality pointless. Asking whether IQ is real is the wrong question. It makes much more sense to ask what IQ scores mean.
