I’ve noticed this type of headline cropping up, which I’ve taken to calling ego baits. The basic template is <some observable habit> is a sign of <some positive attribute>, and I think it works because it appeals to our vanity. The reader goes, “since I have <observable habit>, then I must be <positive attribute>”.
