Despite the enormous body of literature generated (1,727 studies of 1,008 genes), ultimately no unequivocal associations emerged for either positional or functional candidate genes. -- adapted from Lege et al., 2025

The stereotype-threat effect among women was virtually null and not significant (N = 1275, g = 0.04, SE = 0.08, 95% CI [-0.11; 0.20]), and considerably smaller than the original study (N = 45, d = -0.82; 95% CI [-1.45; -0.18]).

Quote from a Science article which made claims of correlation strength but only reported a p value: ("A strong correlation was also found with the AP upstroke/downstroke ratio of thepresynaptic cell only (P = 1.2 × 10–4 versus P > 0.3 for postsynaptic).)

Table of traditional and HYEMA meta-analysis of the red-romance effect. The HYEMA approach, by reasonably prioritizing pre-registered studies, ends up estimating a much weaker, negligible effect of red on women's ratings of male attractiveness.

Unfortunately, small-sample-size studies are so common in psychology that some believe much of psychological research is statistically unfalsifiable (Morey & Lakens, 2016). We suggest that a prediction interval that is extraordinarily wide only because of the sample size of the original study is an indication that the findings of the first study may be unfalsifiable. Indeed, a wide interval could indicate that validating an initial study is not worthwhile given the error associated with it. In this situation, it might be most appropriate to discard the conclusions from the original study and conduct a new, well-designed study instead. That is, the new study is not viewed as replication but, rather, as the first meaningful source of information on the original question.
