QUERY: re:”Personality measures are generally *not* comparable across populations.”.

I assume this is just a casual error of ambiguity, otherwise I’m not sure thats true, because I’m not sure what you’re claiming. It appears you are equating self reporting surveys vs testing?

Self reported anything is nonsense other than as as measure of self reporting. Its useful only for measurement of opinion. And confusing such opinion with fact is the principle cause of the replication crisis.

There are large differences in cultural norm and opinion.

There is very little difference in personality traits by race and culture other than those well known – and those known appear to be neotenic.

And given that conscientiousness is as important or more so than intelligence we should expect opinion to vary accordingly.
