Underrepresentation matters to the extent that the differentiating factor shouldn't have any effect on one's desire to be in a given field, nor on their talent

Underrepresentation matters to the extent that the differentiating factor shouldn't have any effect on one's desire to be in a given field, nor on their talent in that field. Maybe you don't care if some people aren't ending up in the careers that would make them the happiest, but some people do, and they investigate the causes to try to fix it. If women, for instance, are genetically predisposed to liking engineering less or being less capable at engineering, then it's not an issue. If they avoid engineering because of other factors, don't you think that's something that should be fixed?
