Title
Meta-analysis of sex differences in intelligence

Abstract

There is no consensus within the field of psychology on whether there are sex differences in intelligence. To test this hypothesis, 2,092 effect sizes were compiled, representing 15,900,000 individuals that tested sex differences in ability. Men scored 2.58 IQ points (95% CI [1.91, 3.25], I^2 = 99.2%) above women on general ability tests within adults. Whether this difference is due to general intelligence (g) is not clear. Two of the three methods used to test the developmental theory of sex differences suggested that the male advantage in ability increases with age.

Replying to Reviewer 1

Given the current version, I don't have much more to say. Although some points were not addressed appropriately, I don't think it's too big of an issue. There is only one thing I require before accepting: update the supplementary files, along with any missing files mentioned prior. The code is still the same as before (uploaded at 2025-01-06). Remember this is required for all OP submissions. 

Did you update the supplementary files (especially the code)? I still don't see any update in this regard.

The submission has now been updated.
