From the arts technica blog: “A new study indicates that policy-based initiatives can increase women’s participation and competitiveness in math and the quality of the resulting work. The particular experiment performed by Loukas Balafoutas and Matthias Sutter, released February 2 by Science, involved three methods that provided an initial advantage to women in a math competition. The authors found that, in each case, women entered the competitions more readily, but the aggregate performance of the participants was unaffected, and sometimes even improved.”
