There’s a quote that usually gets attributed to Albert Einstein, which goes like this:
“The definition of insanity is doing the same thing over and over again and expecting different results.”
Einstein never said this, and it would be weird for him to have done so considering the importance of replication in scientific experiments. And it’s not the most precise wording to begin with: “insanity” here stands in for “bad decision-making” despite the word evoking mental illness. But the quote is nonetheless beloved by people who want to insist that a change be made and find the twentieth century’s #1 smart guy a handy authority.
