To estimate the mean ES, we used a random effects model with 95% confidence intervals (CI95). The effect was considered to be statistically significant if the CI95 did not include zero. We measured variation in the ESs among and between countries with large (>100) and small ( Table 1). Meta-analysis demonstrated a significant negative association between men’s age and preferences for facial femininity across countries (mean ES = ?0.43; CI95 = ?0.17 to ?0.71). The decline in preferences for facial femininity with age was robust, so that Rosenthal’s fail-safe number was 101, more than 3 times greater than the number of countries (27) for which we calculated ESs. Continuous meta-analyses demonstrated an absence of among-country variation in preferences with respect to NHI (p = .66) and GNI (p = .62). The effect did not differ between countries with relatively small (?100) and large (>100) numbers of respondents (QB = 0.02, df = 1, p = .88), suggesting that our estimates of the strength of the relationships between men’s age and femininity preferences were not affected by among-country variation in the numbers of respondents.
The absence of significant variation among countries in the strength of the association between men’s age and preferences for facial femininity (QT = 24.6, df = 26, p = .54) justified averaging the data across the countries. The resulting pattern demonstrated a significant decline in men’s preferences for facial femininity with advancing age ( Figure 1), from 74% among men aged 30 years to 66% among men aged 70 years. However, SOI scores did not differ across age groups (rS = .05, n = 11 age classes, p = .87).
