Nirvana fallacy, also know as “perfect solution fallacy” is suggesting that no solution is better than an imperfect solution. If I can’t have nirvana, I don’t want anything.
I see it all the time in online arguments. “Oh, you advocate for housing the homeless? Well then why do you have empty rooms in your house? Just fill it with homeless people.” this is an example of the fallacy. It suggests that my solution, “house the homeless” should be discarded because it is not a perfect solution, which would be filling my house up with strangers. The goal is to make me say, “oh, I’m not willing to do that, so we should do nothing instead.”
it does have some qualities of Nirvana fallacy in that it implies my support for a policy is inadequate unless I provide a perfect, personal solution. but thanks for your response.
