my basic sketch of it is that philosophy and rationality are overconcerned with objective reality, and that we should instead focus on how perceptions are subjective and how we relate to one another.
The subjectivity of our perceptions and how we relate to one another are themselves parts of objective reality.
To steelman the position you’re attributing, if philosophy and rationality have been paying too little attention to those parts of objective reality, then they need to focus on those as well as, not instead of, the rest of reality. Or to put that in terms of a concrete example alluded to elsewhere in the thread, nuclear power plants must be designed to be safely operable by real fallible humans.
But they do attend to these things already. Bayesian methods provide objective reasoning about subjective belief. Psychology, not all of which is bunk, deals with (among other things) how we relate to one another. Engineering already deals with human factors.
