I think all of these strategies give the type of student I'm talking about too much credit, as they are mostly emotional creatures not prone to strategic planning. I guess TDTPT comes closest, but I would change it to a phrase I use with my students: "It's fun to be right." IFTBR.

Easy trivia apps were all the rage among my students a couple years ago. Nobody was trying to get a high score or trying to advance to the next level, but if you put a question in front of someone that they think they know the answer to, the urge to get validation for knowing it is irresistible. You've probably seen ads on the internet that work on this principle.

It's why Who Wants to Be a Millionaire always started off with insultingly easy questions, and why easy cards in the class Anki deck are so important for raising participation and morale.
