I think you're referring to confirmation bias which is related but not quite the same. Never the less I understand what you're getting at. I took it to mean that the kinds of problems a programmer encounters is not sufficiently random to properly determine the usefulness of a given language or "paradigm." Which may keep people from switching to new, better tools (or from trying them out at all). The data-oriented design thing is interesting and something I've heard come and go over the years.
