My more-depressing interpretation of this is the value comes as an explanation for being written off by others. Rather than being a way to filter others out, a person with multiple socially off-putting habits or a generally disagreeable demeanor can do This One Weird Trick to then point at their cleverness as the reason why they are standing in a room fun of people that don’t want to talk to them.

There is no need for self-reflection if everyone else is simply too gauche to understand how actually pro-social your nakedly anti-social ruse is.
