This runs afoul of the same mental-block when it comes to worrying about your self-identity. It's trading the possibility of "Oh man, what if they think I'm incompetent?" for the self-certainty of "Shit, I'm a horrible person who lied to them and deliberately wasted their time."

Anybody already self-assured enough to "be the jerk" probably isn't that worried about "being rejected".
