What do you think GM Hikaru IQ is?

you're*

I don't think IQ is directly related to your ability to play chess. The more you practice, the better you are.

IQ isn't directly related to anything

To everyone saying 102, there is a clip of him saying that it is not accurate at all, it's the first question in this video: https://www.youtube.com/watch?v=7E50B4z9ZjU

The average GMs IQ is 135... it's about the top 1% of the population. IQ can go alot higher - there are obviously other factors - but it's clear from the data that IQ matters.
I can see that hurts some peoples feelings but... IQ doesn't care about your feelings.
I suspect Hikaru threw the test because he didn't want to reveal his IQ. I just don't believe a person of average intelligence could possibly be the 2nd best in the world at blitz... it's a mental game, it requires mental processing speed (an aspect of IQ), memory (another aspect of IQ), visual spatial ability (another aspect of IQ...). I've also seen him do memory exercises - not IQ tests but just casual games - and he has a very good memory....

Just out of curiosity, what is your source for your claim about the IQ of the average GM? If I google it, the only hits I get on the topic are highly suspect opinion-based sources like Quora and Reddit...
My source is my memory. I think a Quora post is where I got it but it wasn't an opinion, it was a link to an actual study of the average GMs IQ. But the post isn't coming up and I don't see the link anywhere on google. I guess you'll just have to either take my word for it or ignore it.
Studies have produced mixed results, but many of the studies conducted on this topic are very poorly designed... because they don't control for the other factors like years experience, or number of hours practiced, or something like this. So they're basically asking the question of whether a high IQ individual can beat experienced low or average IQ individuals reliably.... what we're really more interested in is how IQ correlates with progression and with max elo, holding constant the amount of effort. That's the question most people want to know the answer to.
Looking at GMs IQ does a little better job at normalizing the population, since it's the tail end of the distribution and the various contributing factors are approaching their limits.

Well you're free to dismiss the information from your mind. Although... for the broader question of whether GMs have higher than average IQs - I think the answer to that question is pretty obvious.

Indeed. The pretty obvious answer is "no".
And this is based on facts and researches, not your nonexisting Quora thread.
According to Karl Popper's Falsifiable Theories in Epistemiology, Nakamura's IQ would disprove the validity of the IQ Test and the entire Belle Curve.
