And do it right here on HN. Just the other day a member of the Python core team said the Python2 to Python3 transition was be a never to be repeated mistake.

And big groups do it too, apparently. In community groups I'm in saying things like "we tried this but it didn't work" is a regular occurrence. They make for entertaining, self depreciating war stories, letting newbies know things aren't judged too harshly around here.
In fact it happens so often, I wondering if all the posts here saying "of yes - that's right" is some sort of group confirmation bias at work. I wonder if it will be self correcting - and the group later come to the conclusion it was wrong.
