Insisting the other person pay has a lot more signalling implications than you think. Depending on the rest of your personality/appearance, it can make you seem like a cheapskate, or like someone who's overconfident, or someone who gets laid a lot so doesn't care about impressing random women, etc.
You're also viewing attraction in a very weird way. Most romance isn't love at first sight. Making a good impression on someone and seeing them a lot increases the amount they like you, and it is very unlikely that you meet someone for a first date and they totally want to be in a relationship right away, regardless of bill splitting. It's far more likely that they have some impression of you, either positive or negative, that bill-splitting will influence one way or the other depending on their personality and yours.
I think you are right. Thanks for your insight.
The last thread didn't fare too badly, I think; let's make it a monthly tradition. (Me, I'm more interested in thinking about real-world policies or philosophies, actual and possible, rather than AI design or physics, and I suspect that many fine, non-mind-killed folks reading LW also are - but might be ashamed to admit it!)
Quoth OrphanWilde:
Let's try to stick to those rules - and maybe make some more if sorely needed.
Oh, and I think that the "Personal is Political" stuff like gender relations, etc also belongs here.
