“…Evidence from more than thirty studies shows that stable and consistent universal gender differences in SEI exist in general population (Furnham, 2001;Furnham & Budhani, 2002;Furnham, Crawshaw, & Rawles, 2006;Furnham & Shagabutdinova, 2012;Stieger et al, 2010;von Stumm, Chamorro-Premuzic, & Furnham, 2009), with the strongest gender differences observed on mathematical/ logical and spatial intelligences, followed by overall ('g') and verbal intelligences, with significantly higher self-estimates provided by males than females (Furnham, 2001;Furnham, Hosoe, & Tang, 2003;Rammstedt & Rammsayer, 2002a,b). The magnitude of gender differences in mathematical/logical, spatial, overall and verbal self-assessed intelligences were further revealed in meta-analytical study (Szymanowicz, Chamorro-Premuzic, & Furnham, 2011), with the biggest weighted mean effect sizes for mathematical/logical, (d = .…”
