A number of people who work in IT incorrectly assume that ‘anecdote’ is the singular form of ‘data’. That is, if they or someone they know has had a bad experience with something, that thing is to be feared and avoided, or if it doesn’t align with their current idea of the way things should work, the best thing to do is undermine the project. If I hear the sentiment “nobody in the industry does it that way” again, I’m likely to scream.
