But the claimed phenomenon here is that it's (almost) always easier for you to come up with a solution to someone else's problem than for them to do so, not just that some problems are easier for one person than another. There are problems with this claim, I think, but the absence of free will is not an explanation, or at best just reduces it to the question of why, granting the claim, the determinism (almost) always leads to this bias.

(For that matter, nothing in the linked article depends on whether or not we have free will.)

The outside with the solution doesn't have to live with the result and likely doesn't comprehend the un-stated nuances of the situation.

That makes problem solving easy.

Yes, that's the kind of thing I had in mind by saying that I thought that there were problems with the claim.

That would just move the question *, not give an answer.

* to: "OK, and why would our deterministic movements solve them easier than the deterministic movements of the person with the problem?"

Selection bias: people tend to talk about the problems that are hard, and we tend to see the ones that we can solve. (Okay, this has nothing to do with free will I guess...)
