the fact of the matter is that most people don't really care about what's correct/ what's insightful/ what's true etc., they just want to feel good.

Okay, I take huge issue with this. I'm a graphic designer; critique is a regular part of my life, and believe me, I get plenty of it every day. Of course I want to improve my work, and of course I'm receptive of critique from my colleagues who are way more experienced than me. But it's perfectly possible to give critique that doesn't make the person feel shitty. My hangup is inferior Te - I pretty much need the validation of someone who knows what they're talking about to feel like I'm doing the right thing. And if I'm not doing the right thing, it helps if someone at least acknowledges that they know what I was going for, or something to that effect. When that person does nothing but point out flaws in a blunt, direct way, I start to feel like I'm doing nothing right. It feels shitty.

So sure, please do help me out by letting me know what I can improve. But don't make it the verbal equivalent of a red chisel-tipped marker marking all of my mistakes. I'm doing my best to meet people in the middle and not take criticism personally. I really appreciate it when the more direct folks out there do the same for me and try to be tactful about it.
