Some attribute it to famed physicist Albert Einstein. While Einstein is a fount of wisdom who’s come up with some pretty memorable quotes, the insanity definition isn’t one of them.

Albert Einstein supposedly defined insanity as doing the same action repeatedly but expecting different results each time.

Insanity, it turns out, is American cannabis policy. Let me say this at the outset: This is not about partisan politics or blame.

It seems to be our favorite saying: The definition of insanity is doing the same thing over and over and expecting a different result. Like many witticisms attributed to Einstein, he never said it.

The definition of insanity refers to perseveration, which is the compulsive repetition of an action—not perseverance, which is noble effort.

Japan exemplifies the economic version of Albert Einstein’s belief that trying the same thing over and over again expecting a better outcome was just nuts.
