usability death spiral
the condition where the longer a programmer or designer spends dealing with a particular piece of code (without observing real users using it), the more logical and usable it appears to be.
This is a metaphor to the aviation “Death Spiral” where the longer a pilot spends in a turn (in conditions where they cannot judge the horizon), the more likely they are to forget they are in a turn, fail to apply enough power to the turn and descend until they crash.
