An interesting example: a few months ago I dropped something on my toenail and it turned black. Wading through WebMD etc (which is where google was sending me) was not helpful, especially in between the popups and autoplay videos I finally restricted my search to wikipedia and quickly found out that it's called 'subungual hematoma' and "usually self-resolving", which is what I needed to know. Recently I tried this query on GPT-3 and it worked well too: Prompt: Something fell on my nail and it turned black GPT: Possible causes for a black nail include: trauma to the nail, a melanoma, or a subungual hematoma (a collection of blood under the nail). If the black nail is accompanied by pain, swelling, or redness, seek medical attention. If the black nail is not painful and has no other symptoms, it is likely a subungual hematoma and will eventually grow out with the nail.
