@dyske >So. IQ tests do reinforce this unhealthy phenomenon, by partitioning it's participants into two groups (below/above 100).They are "certified" confirmation, that you're "better" than someone else.
Moreover I have yet to see a serious study where IQ is taken as a sole indicator of perfomance.
Again. IQ doesn't claim to be anything but a metric for pattern recognition. They're not "certified better" or "more performant". That's what you are claiming.
You do have a point in that people shouldn't view it as an "everything will go great" card, but that's why most kids who are tested at school don't really get their numbers told.
