Has there ever been research on the accuracy rate of fortune cookies?

They aren’t even Chinese. :)

There have been a few stories of fortune cookie lottery numbers winning. Here’s one: https://www.npr.org/2022/01/25/1075558463/a-veteran-won-a-4-million-lottery-prize-using-the-numbers-from-a-fortune-cookie#:~:text=Mega%20Millions%20winner%20got%20numbers%20from%20a%20fortune%20cookie%20The,out%20to%20be%20extra%20fortunate.

I had a fortune cookie that shocked the hell out of me, was having Chinese with some friends when the cookies came the one I was reaching for was broken so I ignored it and reached for another, now the shocking part the fortune read ” you will ignore the first cookie” I have never had one that accurate before or since.
