Every time you hear about a gender gap in STEM, it's because someone didn't do their homework and are operating from a false premise. The truth is there's no gender imbalance in STEM. This is this is the best kept secret out there: they omit biological _sciences_ from the "STEM" definition because women are an overwhelming majority of those fields. When you add them back in there is. no. gap.
This is all just the result of gender feminists playing games with terminology to benefit their pet projects. It's since taken on it's own life and now people think we need more women in STEM. The REAL gender gap is in education and academia. Men are only about 13% of school teachers and that's got to change if we want our kids to grow up with a balanced view of the genders.
