📄️ Nirvana Fallacy
The Nirvana fallacy, also known as the "perfect solution fallacy," is a type of informal fallacy that occurs when someone dismisses or rejects a proposed solution or course of action because it is not perfect or ideal. Instead of considering the proposal on its merits, the person argues that unless the solution meets an impossibly high standard of perfection, it should be rejected in favor of doing nothing or pursuing an alternative that is also unrealistic.
📄️ Sunk Cost Fallacy
The sunk cost fallacy is a cognitive bias that occurs when individuals continue to invest time, money, or resources into a decision or project based on the notion that they have already invested so much that they cannot abandon it, even when it's clear that further investment is not justified. In other words, people often let their past investments (sunk costs) influence their decisions about the future, rather than making rational choices based on current and future factors.
