In the world of martial arts this is expressed essentially by the fact that you work with the same people so this tends to a false sense of generality in ones understanding. Within any particular discipline there's confinements because there's a core focus and rubric of things you do with is necessarily exclusionary and reductive because of the constraints of time.
Serious martial arts practitioners (think career professionals) claim people will plateau indefinitely, as in for the remainder of their lives, unless they effectively practice shoshin. This can go in odd directions. Take George Dillman for example, who has developed a mechanism that he, and maybe nobody, really understands and as a result he's considered a fraud although he and his students experience it as genuine.
True shoshin demands an open investigation as to why, where, and how people feel a mechanism and a good faith assumption that there's something poorly understood there.
What shoshin demands is ridiculous, absurd, and necessary. People will look at you incredulously. You will be mocked and even discredited.
It's why it continues to tend young.
It's hard. The older you get, the more opinionated you get and with opinions come inflexibility so the less you are open to new ways of thinking, even those which may be generally superior.
I've tried hard for years not to fall in that trap as I age but I realize I have nonetheless.
