The Nirvana fallacy consists in comparing existing solutions with ideal, perfect ones—which are often unrealistic. A form of perfectionism, it can lead to dangerous thinking and harmful decisions.
“Le mieux est l’ennemi du bien” wrote Voltaire in 1772
Also called the “perfect solution fallacy”, the Nirvana fallacy is based on faulty reasoning, where an argument assumes that a solution should be rejected because some part of the problem still exists after the solution is applied
Solutions that improve safety but do not completely eliminate a risk are often the victim of the Nirvana fallacy.
