The friggin "definition of insanity" quote that is usually misattributed to Einstein. From some cursory research, a lot of first appearances of the quote come from the 80s, though I saw a few different sources from Narcotics Anonymous pamphlets to mystery novels.
Jokes aside though, misattributed quotes are quite the phenomenon. Is it deliberate? Is it some sort of mandela effect? It's really weird sometimes, but like Gandhi said, don't believe anything that comes without a verifiable source.
Ehhhh, I want to agree but practice is expecting the same result, minor incremental improvement. In scientific experimentation, one should not be expecting anything, that's researcher bias.
