Also you're comparing 99% to 1%.
hypothetical example
In one year 100 bridges were built
99 bridges built by males. Only 9% of them fail.
1 bridge built by females. 100% of them fail.
Oh but because 9% (8.91 bridges) of those male bridges failed that means they did worse than women who only had 1 bridge fail!
Look at it this way: how many forcibly-all-male engineering teams could have averted a bridge collapse by hiring one female employee instead of the one guy who flubbed the math? It follows that if this bridge collapsed because a competent male employee was passed up for an incompetent female employee, then historically speaking,
hundreds of bridges have collapsed for the exact same reason, but with the genders swapped.
So yeah, I'll agree that enforcing a 100% gender quota for an engineering team is a bad idea because it's inherently loveist. But it would take a hell of a lot more affirmative action to equal the amount of damage done to engineering institutions because of the fact that they're gigantic insular boys-clubs. I say this as an actual engineering student lol.
My experience working in construction is that everyone vehemently hates engineers.
Lol
