It seems that in many, probably most cases people are being taught, from a very young age, *what* to think, not *how* to think for themselves.
Parents teach their kids how to make choices similar to theirs, and they might get varying degrees of upset and to exert coersion when the child's choices are different from theirs. Mimicking others. Being concerned with what others think. Berating. Mocking. Shaming. Withholding affection, goodies.
Especially if those choices are inconvenient, unconventional etc.
Freedom and independent thinking are likely to be inconvenient to others.
It's understandable, to a degree - where do you draw the line, and how do you influence the child ? But that's the thing - influence might be the wrong approach, at least in this way.
Parents, school, job, society at large, partner, "experts" on "hoarding", psychologists and practitioners - everyone is doing this.
"Experts" on "hoarding", in their books, ostensibly infite the person to make the choices for themselves.
They even say things like "we can't make you discard - nobody can make you discard" - which, on the face of it, is exactly the right thing. But then, they try to influence person's choices towards discarding, introducing the framings of "pathology", "mental illness", "diminished competency when it comes to possessions", and generally questioning the person's judgement all around. The decision making they invite is heavily biased towards utilitarianism and conformity - "do you really need this ?", comparisons to what "most people" would do, etc.
Let the person decide, without any of these attempts at influence.
Food for thought - to be discussed.
