I have a few examples of this I can think of to explain my question.
Scenario #1 - You want to help somebody with their question but you don't know how to help them. You know other people know how to help but no one wants to help. So in order to prompt someone else to help the person you want to help, you intentionally provide a wrong answer. This prompts someone else to provide a correct answer.
Scenario #2 - You see two people of your political party arguing so you pretend to be of the opposite political party member. The two arguing people join forces and attack you instead since you're the common enemy. Mission success, you wanted to unify them and you did.
In both scenarios you're doing something intentionally "different" to have an intended outcome. Like normally, you wouldn't provide a wrong answer, but in this case, you did to prompt someone else to do something.
What would you call this? I'm thinking of "reverse psychology" or "manipulative" but I don't feel like those make sense in either of these scenarios. Thanks in advance.
