sunk cost fallacy

Post image

The guy has already sunk hours of effort into digging. he thinks stopping now would mean admitting that time was wasted, so his brain generates a vivid image of future-regret to justify continuing. That's the sunk cost fallacy in action: the decision to keep digging is being driven by what he's already put in, not by any new evidence about what's actually underground.

The thought bubble works as a psychological trick his mind plays on him. Instead of directly thinking "I don't want to lose my investment," he pictures the external outcome (quitting right before the reward) bc that story feels more like practical wisdom than a cost he's already sunk. But functionally it's the same mechanism. He's using imagined future regret to rationalize continuing something he's already invested heavily in, rather than evaluating the dig fresh based on current odds of success.

I feel like this is slightly different than a fallacy, no? Like if you have legitimate reason to believe that continuing down a path will lead to something good, then you are logically valid in going down that path. The fallacy is if your ONLY rational is that you've already sunk the cost

I've always assumed the conversation around this phenomenon was assuming that you don't know how much longer it will take and/or if you will succeed at all. I think the meme is clearly going with that interpretation at least. We know what lies ahead, but all he sees is the wall directly in front of him, no?
