Based on IQ ~~ parental edu. of only .14, I take it without correcting for measurement error.

Depends what you consider small. If you adjust for measurement error, r will be around 0.3 in this huge convenience sample.

Depends on the issue. I find .34 for the NCDS but IQ is measured in childhood and openness at age 50>

.20 in the GSOEP, but with obviously crappy measure of intelligence (MWT-A) & only four items openness>

NLSY .06, but measure doesn't capture the "intellectual" side of openness. Corrs not corrected for measurement error.>

Okcupid data is another huge convenience sample with nonstandard & suboptimal IQ measurement. Did not examine the link in it.

for this question, I'd say representative sample>>convenience sample because of endogenous selection bias, cfhttp://www.the100.ci/2017/03/14/that-one-weird-third-variable-problem-nobody-ever-mentions-conditioning-on-a-collider/ …

Yes! Way better... Key take-away for me is that O/I & IQ are (moderately) correlated but distinct. This is not universally acknowledged.

It isn't? Do people believe that it's the same? Or that it's uncorrelated?

It's long been 'common knowledge' that personality and g are unrelated. Not quite true, and possibly very wrong if we use other rating data.

Again, I'd say this is a matter of important distinctions in operationalization & measurement. "Very wrong" seems extreme, though possible.
