I never said it did. Just that people tend to learn from their mistakes. Are there people who will make the same mistake different ways over and over again? Yep

I never said it did. Just that people tend to learn from their mistakes. Are there people who will make the same mistake different ways over and over again? Yep (I’m one of them). It’s not an issue, I learn and get better at spotting the mistake when I review other’s code and others point it out when reviewing my code. That’s why I said “exactly once” since once you know what it looks like, you can spot it in a review.
