People Took to Social Media to Disprove Popular Sayings

“The definition of insanity is doing the same thing over and over and expecting a different result.” That quote is famously misattributed to Albert Einstein, and we’re sure you’ve heard it a million times already. But guess what? That’s actually not the true definition of “insanity,” and it isn’t what Einstein said at all. Here’s what it really means.

“The condition of being insane; derangement of the mind.” There’s also “extreme foolishness” and “a foolish or senseless action, policy, statement, etc.” In addition, there’s the definition from the judicial standpoint: “such unsoundness of mind as frees one from legal responsibility.” First originated in the 1580s. So, yeah. Those are the real meanings of insanity.
