If there is an ideal amount of some personality trait then for most people the advice would be "do more of this" even though for some others it'll have to be "do less of this" depending on where you're coming from. When I was young I definitely did a bit of over-socialization (everybody seems to like music festivals so I guess I must like them too if I don't want to be a weirdo?) but as you can see in the comments to this post, as we get older it's easy to get into a pattern where anything you're not familiar with is instantly met with suspicion or derision, and a lot of people don't like this about themselves, which is why this blogpost resonates with them.

Also, "liking something intrinsically", what does that even mean?

You've never discovered something and felt the indescribable, joy-inducing draw of its appeal? Listened to some music and immediately jived with it? Blaming familiarity bias and "old man yells at clouds" is a disappointingly small-minded critique. It's the opposite: I've lived long enough to thoroughly experience the joy of newly discovering something that feels like it fits me perfectly; conversely, I've tried to appreciate other things enough times to know never to waste my time trying again. Especially for the sake of others.

I've learned that liking things behaves a lot like attraction. It has no reasoning or logic, it happens organically, and when you know, you know. Thus, I would never deign to pretend to like something I've found I don't.
