THREAD: 12 Things Everyone Should Know About IQ
1. IQ is one of the most heritable psychological traits – that is, individual differences in IQ are strongly associated with individual differences in genes (at least in fairly typical modern environments). https://t.co/3XxzW9bxLE
(Note that the Flynn effect shows that IQ isn't 100% genetic; it doesn't show that it's 100% environmental.)
For example, though far from perfect, IQ is the single-best predictor of job performance we have – much better than Emotional Intelligence, the Big Five, Grit, etc. https://t.co/rKUgKDAAVx https://t.co/DWbVI8QSU3
If IQ isn't a valid concept, no concept in psychology is valid.
Conversely, IQ-denial could cause real harm by stalling the development of such interventions.

It doesn't happen because you want it to happen.
It doesn't happen because you made it happen.
It happens because you allow it to happen.

There is a fine line between persistence and stubbornness.
