I was trying to avoid shaming you, but I'm sure I could have done a better job of that, especially because I'm posting from a position of authority and that magnifies such effects by a million times.

One of my teachers once told me "I did a Ph.D. in psychology at Stanford and I learned just one thing from it: that punishment is not good for learning." Hopefully we can get to a state where there's less punishment and more learning. I think examples are good for learning, so I hope you can stop feeling guilty and just take it as an example.
