Then what is the solution? Because as far as I can tell, unless you force people to be 50/50 in a profession, it will be basically impossible to get rid of the implicit bias people have in those jobs. And I'd be willing to bet that applies to other immutable characteristics, not just gender.
People working in those sectors themselves acknowledge there is implicit bias. And the difference remains even when you control for dangerous work (I.e looking at people who only work desk jobs).
You may never get to 50;50 but there is no reason for the disparity to be as large as it is - any more than women (or any any other immutable characteristic) don’t self select not to be CEOs or similar.
And articles like this tell you you don’t have to look too far to find out what the real reason is.
