> Signalling too little interest might result in missed opportunities, but excessive eagerness could prematurely resolve uncertainty in situations where expectations about the prospect of a relationship are actually not aligned.

There's something else with aloofness that I thought a lot about when dating. Being aloof, as in unconcerned with outcome, signals fitness, when done properly, because it signals a lack of need to invest in this particular interaction. This does not mean being unkind, just that when someone signals that they have lots of resources and other options, it can come off as being aloof. Not uncaring, just not desperate to escalate. So a "too quick" escalation signals desperation (I'm unfit and cannot attract others), lack of patience, or unconcern about the deeper person - "I've seen enough to charge". All red flags.

I actually think this is a better reason to be cautious in social encounters, or at least patient, than the one presented in TFA, at least in modern times.

Being able to signal "I'm playing the long game" is attractive all around.
