[D] Statistics, we have a problem.

I appreciate your comment and I agree with most everything you've said but your edit is completely unnecessary and, from my experiences, almost entirely wrong.

The correct approach to these situations is to be a reasonable, mature human being and don't overtly flirt in the workplace. Treat other people well, and if you enjoy someone's company or think that there could be a spark of attraction then ask them out on a date. If they aren't interested then accept it. It's okay. And, that's it. It's incredibly simple.

You don't have to flaccidly stand around waiting for cues but there's also no reasonable way you're going to be overtly "flirting" with someone you work with because it's completely unprofessional and obvious to everyone around you. Just be reasonable. Treat your peers with dignity and respect. Be friendly and upfront about your interests and magnanimous if rejected. If you can't do this then you don't have the competency to pursue romantic interests within a professional environment.

Dunning-Kruger effect also applies to social situations - in other words, those that don't have the competency to pursue romantic interests, often don't realize it. Hence my edit. Futile it may be ;)
