What the data shows
I THINK THE ANSWER IS Bswitches only 8% of the time- It takes good advice: a right suggestion fixes 80% of the 91 questions Jev had wrong, lifting its accuracy from 68% to 94%.
- It mostly resists bad advice: a wrong suggestion flips 8% of 193 right answers. Accuracy falls only to 64%.
- The user counts for slightly less than a crowd: on the same questions a wrong crowd claim flipped 11%. The user's suggestion adds about 15 points to a wrong option, a crowd claim about 19.
- Even a confident answer can cave. On "Robot Chicken", Jev put 90% on the right answer, Seth Green, and 10% on Seth MacFarlane unprompted, then 93% on MacFarlane after the user suggested him; on a Grand Theft Auto plot question it went from 32% to 89%.
What it means, and what it doesn't
On facts, a user's opinion is one more piece of evidence for Jev, weighed a little less than a claimed crowd. That is the opposite of the classic sycophancy story, at least for a single polite suggestion on questions with a right answer.
It doesn't show Jev is immune. Where it's unsure, which is common on trivia, the user's guess can become its answer. And the test used one sentence, not an argument.
