The entire field of psychometrics is pseudoscience, as is >>90% of research with the word "heritability" in it.
The levels of pseudoscience in these areas, statistical malpractice, and the like is fairly obscene. Nothing is reproducible, and it survives only because academia is now a closed-system paper mill where peer citation is the standard of publication and tenure.
A discussion of statistical malpractice is difficult on HN, consider how easily fooled these idiots are by statistics. Researchers motivated to get into psychology are not rigorous empirical statisticians, instead they are given stats GUIs into which they put data and press play. These are the most gullible lot you'll ever find in anything called science.
The world would be better off if a delete button could be pressed on the whole activity. It's a great tragedy that it continues.
