Yes I know, your least-favorite idea goes here. But seriously, someone must have come up with the concept before. Like a bad get-rich-quick scheme could fall into this category, where joining the scheme makes people lose money and become more desperate, so they become more likely to do desperate things like invest more in the scheme. But it can apply to a number of other bad ideas.
That’s the “sunk cost fallacy”
Sunk cost fallacy is definitely a subtype, but I’m going for I guess the more general concept of an idea that becomes more popular the worse it does
Sunk cost fallacy is when you use previous expenditures to justify new expenditures so as not to “waste” the previous expenditure. It doesn’t imply the idea gets more popular like op is looking for.
*waste
Sorry for being pedantic. Could’ve just been your autocorrect or not your first language lol no offense meant.
Fair
