What life purpose a very low iq person is supposed to have?

[Never_give_up]

after all he can't do much in this world cause of his mental disabilities. Is he cursed not to do anything of value in this world?

[Stick]

there is no need to have a purpose.

If a clinically low iq person exists, but they have high emotional intelligence or discipline, they can get more done than a higher iq person with crippling anxiety and inconsistency. There isn't in the world some kind of magical scoreboard of what is of value and what isn't, SPECIALLY in capitalism. Morally, we might make those distinctions but it's highly contextual. Capitalism doesn't give a shit about that.

I've seen people on YouTube that told their stories and I believe by what they said they have some mental disability by being slow to learn, but somehow they still had verbal fluency and world knowledge.

How? Problem solving skills are likely not completely tied to all regions of the brain. We know very well for example, social intelligence can be the opposite to traditional problem solving like for autistic people, they can focus at something very niche and specific and drop social bullshit that gets in the way.

The issue is being completely shitty at everything. IQ is just what traditionally an IQ test measures, it's not all areas of the brain or life decisions, personal environment, inclinations, etc.

Look at someone like Chris Langan, that guy very likely has some of the highest IQs in the world, yet he's sort of this fundamentalist Christian and didn't know how to navigate university bureaucracy and had to quit because he came from a super poor rural area american family.
