In my research field, one characteristic of institutions is their “rational myths”; ideas that people tell each other are true, and believe are true, but which are under-explored, unverified, and under-challenged. Belief in these myths leads to supposedly rational actions that don’t necessarily improve efficiency or performance, but are done because everyone else does them, and everyone collectively believes they’re what one does.
We know, from Derek Jones’s Evidence-based software engineering, that what we know about software engineering is not very much. So what are the rational myths where you work? Do you recognise them? Could you change them? What would it take to support or undermine your community’s rational myths, and would you want to take that risk?
