Yipe! I hope this is hypothetical, and we're not getting a glimpse into how you (would?) act as a manager.
But even in my most pragmatic, cynical mindset, remove the gender from this entirely. Beautiful people get ahead, regardless of gender. For instance:
Here is another hypothetical anecdote to counter yours: a handsome, sharp 23-yo man walks in to his manager's office asking for more, and the manager sees a potential go-getter. A beautiful 23-yo woman walks into her manager's office asking for more, and the manager is influenced by his subconscious belief that all attractive women are stupid.
Or how about a 23-yo person (say, Chris), at a start-up that gets a raise because that person creates a positive work atmosphere by being friendly and fostering coworker interaction -- even if that person is not the strongest coder, they may be bringing more value to the team. Maybe everyone else agrees with this raise!, because at one time or another, Chris made them feel "included" in some way. The only person who disagrees is Chris' cubicle mate: a cynical lone-wolf type who spurns others' efforts to be inclusive, and watches from a distance as the rest of the office builds inter-office relationships. Months later, if given a pulpit, that lone dissenter may make some statement like "Chris was given a raise due to petty office politics despite being a mediocre coder," and maybe people hearing this who weren't there won't know how truly valuable Chris was.
But enough hypotheticals. I'm worried that they aren't productive and may be needlessly inflammatory.
For what its worth, as a former tech recruiter, a female candidate had a 90% chance of hire at 70% or greater hire rate then a male candidate.
What that means is, if the company felt the female candidate was less qualified, but had potential then another male candidate, they would be hired. And, all things being equal (subjectively), had a greater opportunity of hire rate (our fee's, thus tracked). "Get a female in tech, get a placement," theoretically spoken.
I am just agreeing with MChurch mostly. It may however, not be so granular as he cites, rather, the fact that the % of females in the area of tech is so low, that selection bias towards females becomes an "issue" to look for more female candidates.
In other words (because I tend to ramble and befuddle what I am trying to say), little females exist in tech. If you get a qualified candidate in tech that is female, that is a more rare event, and thus worth more attention and notice (subconscious or otherwise).
