'A new study argues that the number of women in Science, Technology, Engineering, and Math (STEM) can be increased by simply making grading policies within the fields less harsh.

In a paper titled “Equilibrium Grade Inflation with Implications for Female Interest in STEM Majors,” Naval Postgraduate School professor Thomas Ahn, Duke University economics professor Peter Arcidiacono, Duke University researcher Amy Hopson, and James R. Thomas of the Federal Trade Commission argue that STEM programs at colleges and universities lacking female enrollment can be attributed largely to harsh grading policies in these fields.

The researchers take the position that universities are discouraging students, especially female students, from pursuing STEM majors by allowing differences in grading policies and study time across different fields to exist. They contend that “harsher grading policies in STEM courses disproportionately affect women,” because women are more impacted mentally by receiving poor grades.'
