The dating playbook suggests following the same steps to acquaint ourselves with someone new, no matter how we meet someone. Oftentimes the only difference lies in the speed with which we transition from strangers to…well, to something else.
First, the physical attraction, which we know takes seconds.
Second, we look for more subtle physical cues, like speech, hand movements, tics (if any), gait, eye contact and so on.
Thirdly we begin to observe behavioral traits such as social adaptability, listening skills, the ability to empathize, acceptance of flattery, ability to follow implied statements, reaction to irony; all the nuances of language, whether literal or otherwise.
This progression happens on first dates after discovery on a sex-matching site or after months of coy consideration at work. It’s the reason we want to make a good impression on a first date, because the cliché happens to be true: that first impression sticks. It matters not whether we’re looking for a hook-up or marriage, the pattern remains the same and resulting judgement takes only a few minutes.
As an automatic process, we’re unlikely to change it, so I guess it must work. But it is only a beginning.
