Just do it, say "oops, turns out I was wrong about X". Apologize for inconvenience if its appropriate (if other people made plans or were mislead by it). Here's what not to do: * Enter into a (lengthy) explanation of why you thought you were right, because you heard it from X, or read it at Y, and go back to find and share your (wrong) sources of misinformation. ("I saw a documentary on how the moon landing was faked, and didn't realize that it was fabricated because the people in the documentary said it was true.") * Explain that lots of people share the same (wrong) view, that it's a popular misconception or suchlike. ("Lots of people agree that the moon landing was faked, there are many books and TV programs about that.") * Explain that, had certain other things happened differently, you would have been correct. ("When I said that COVID would never spread outside of China, I was assuming that the blockade in Wuhan was 100% effective.") * Say that, while you were wrong in the current situation, your assertion would have been correct in various other situations. ("When I said object oriented languages don't allow multiple inheritance, I thought we were talking about Java and not C++").
