◆カロリンスカ研究所の研究によれば、生活水準が向上しても、心理的な性差が続くことが分かりました。女性は特に改善された状況から男性よりも利益を得る傾向があり、これが「ジェンダーパラドックス」と呼ばれる現象を一部裏付けています。
◆研究者は、国の生活水準と心理的な性差との相関を調査し、性格、言語能力、感情などの分野で性差が広がることを発見しました。また、平等や経済状況がこれらの変化にどれだけ影響するかは不明であり、今後の研究が求められます。

生活水準の高い国では、際立った性差が残る(Distinct sex differences persist in countries with higher standards of living)

Abstract

Some studies show that living conditions, such as economy, gender equality, and education, are associated with the magnitude of psychological sex differences. We systematically and quantitatively reviewed 54 articles and conducted new analyses on 27 meta-analyses and large-scale studies to investigate the association between living conditions and psychological sex differences. We found that sex differences in personality, verbal abilities, episodic memory, and negative emotions are more pronounced in countries with higher living conditions. In contrast, sex differences in sexual behavior, partner preferences, and math are smaller in countries with higher living conditions. We also observed that economic indicators of living conditions, such as gross domestic product, are most sensitive in predicting the magnitude of sex differences. Taken together, results indicate that more sex differences are larger, rather than smaller, in countries with higher living conditions. It should therefore be expected that the magnitude of most psychological sex differences will remain unchanged or become more pronounced with improvements in living conditions, such as economy, gender equality, and education.
