Sunk Cost

Cognitive bias

Continuing with something because of what has already been invested in it, rather than judging it on its merits from this point forward. Past costs are gone either way.

An everyday example

“We've spent two years on this project, so we have to finish it, even though it's clearly failing.”

The same move in this debate

“I've eaten meat my whole life: it's far too late to change now.”
