> This one’s notable in that it puts an entire passage in quotes, but it turns out the passage was not in Cheung (1983) at all—not on page 8 or anywhere else in that article—it actually came from a collection from 1998 of old Harvard Business School exam questions.

One of my pet peeves is the chain of citations that will inevitably spawn from this. No author can be bothered to go find the original source and just cite that, so this inaccurate (and since retracted) quote will end up propagating itself for decades if not centuries, with each author citing the work that they got the story from. Eventually, hundreds of years from now, someone will be crazy enough to try to work their way down the chain to track down the original, only to discover it isn't there.
