I think it would be fair to say that at least a few people can do a small amount of 4d visualisation.

Agreed, I don't think anyone has a good grasp on, say, 64K D, but we can do a bit better than just 3.

I’ve heard people claiming that they can but I’ve never heard compelling evidence that they’re directly visualising 4D objects rather than 3D projections of them, or some symbolic representation (arrays of numbers etc.)
