Coût irrécupérable 💡
Sunk-cost fallacy (in relationships & life)
What it is (one line):
Over-weighting past investments (time, money, love, identity) when deciding what to do next, even though only future costs/benefits matter.
Relation to abusive relationships:
“You’ve given years, shared rent, pets, memories—leaving ‘wastes’ it all.” That perceived waste keeps you paying
sunk-cost fallacy is identified and taught as a mistake in both economics and business courses, apparently to good effect: there is evidence that graduate students in these fields are more willing than others to walk away from a failing project.
