It's still surprising that we don't have strong evidence that higher IQ is associated with greater happiness.

Between countries it is, but only weakly so within countries. Tinkering with happiness is not so easy as material gains.

But why not? Higher IQ should make it easier to evaluate potential mates, avoid stupid stuff, make long-term plans, exercise, eat right.

And it does, but happiness comes from many things, esp. connecting with peers, which high IQ is detrimental to doing. At least, my take.

Would be interesting to have IQ~happiness data for a large variety of countries to see if the slope is slightly positive within each.

Or whether there is some golden area for maximum happiness (the dystopian finding!). Would be quite annoying if that was true.

Should do a response-surface analysis instead of just linear regression, given sufficient sample size. E.g. gaussian process.

Feel free.
