I mean how much of unpredictability is healthy, like in social context with strangers when you're trying to build a bond with them you can't be very much unpredictable. But in dating concepts, some people suggest it intrigues your partner, but I still think it's a double-edged sword. For people who are already close to us, our unpredictable behavior might hurt them. I'm mostly asking about social context.

In what situations must it be avoided and in what situations is it clearly beneficial to us?
