Analysis: ChatGPT is great at what it's designed to do. You're just using it wrong

It doesn't take much to get ChatGPT to make a factual mistake. My son is doing a report on U.S. presidents, so I figured I'd help him out by looking up a few biographies. Garry Wills famously wrote "Lincoln at Gettysburg," and Lincoln himself wrote the Emancipation Proclamation, of course, but it's not a bad start. Then I tried something harder, asking instead about the much more obscure William Henry Harrison, and it gamely provided a list, nearly all of which was wrong. Books about Harrison, fewer than half of which are correct.
