So you've made a mistake and it's public
“I neglected to look at relevant data before deciding to fund Wikimedia Antarctica”<p>This seems unreasonably sane, compared to actual real-life investors.<p>I think it would be a lot more impactful with a mistake that wasn’t endemic to the relevant profession.<p>How about: “I failed to realize that economics is a social science, and treated it as a field of mathematics”..?
