Philosophical consideration: maybe that bias would also incorporate some assumption of familiarity (https://xkcd.com/2501/ https://xkcd.com/2501/), and a further implicit expectation that this familiarity (aka unwritten/tribal knowledge) would also implicitly contribute to the raw material necessary to rebuild from some baseline axiom. In other words, maybe everyone says only X Y and Z from their field is necessary/the most important, not (just) because nothing else is on their radar, but because when they think of their field, simply just mentally reasoning about X, Y, or Z is all it takes to take into account all the connected associations, without the feeling this reasoning takes much mental space or effort; and maybe this is an interesting mental fallacy.
