Got it to 0.5991561181434598 after a while (totally random would be "0.5"). Not sure how "free will" comes into play, if there was indeed free will, I could have freely decided to only press one, and the Oracle would have had close to 100% certainty. Rather, what it measures is randomness or predictability, which is not the same thing as free will (especially "after the fact", e.g. after the choice is made).

I think I might have missed the point of this. Is this just a predictability score - really simple one?

At first I was stuck at ~0.95 but I was just striking the keys really fast but then I concentrated and looked at the keys and really tried to feel which key I wanted to press and it worked. I was able to score lower ~0.4. I'm computationally irreducible for now.

Well, if your score is .4, a computer could predict you with .6 accuracy just by predicting what you will press and then guessing the opposite :)

but how does it know to use the opposite for him and not for other guesses? I make a similar mistake when I try to remember something by noting "it's not the choice I'm naturally inclined to choose, it's the other one". After I get used to using that heuristic, the correct choice becomes the one I'm naturally inclined to do, but then I have trouble remembering "is it the choice I'm inclined to do or the opposite". I've since ditched that heuristic when I realize I'm doing it because it is quite detrimental.

Right. It tries to measure how random your brain's PRNG is, which has nothing to do with free will. A simple computer has no free will at all, but after being instructed to type randomly, it will score close to 0.5 without fail.

The "free will" quote comes from a Berkley quantum computing student, who chose keys as independently of pattern as he could [1], and this seems to take it out of context. It might make sense to retitle this submission to something marginally less clickbaity, like "test how predictable you are."

I had a professor who, when playing games where the best move was to choose randomly (for instance, in a CCG, forcing the opponent to discard a card from their hand that you designate without seeing their hand), would always roll a die or otherwise mechanically randomize their choice, to ensure that they never exhibited potentially exploitable patterns in selection.

When I was little (and had too much free time) I memorized many digits of some transcendental numbers. The only (semi)practical use I've found for that knowledge, is that I can use it as a reasonably good pseudorandom stream. If for some reason I have to choose things pseudorandomly. Pick an arbitrary starting point in pi, and press 'd' for even digits and 'f' for odd digits, I get around 0.49 accuracy with this orac…

Well, that only shows that this oracle can be improved. It should be able to recognize that pattern from a well known transcendental number.

So. I have done a similar thing for a while now. I call it adversarial selection. I ask a participant(p) to guess a number [1,10] repeatedly. After they guess a number, I immediately tell them my guess of their selected number. Immediately after I guess they are instructed to make a new guess and tap the table indicating they have picked a number. The point is to go through these generations very fast. Often what I'l…

Are you sure the 10% chance isn't standing out more in your memory? It would be interesting to measure this over hundreds of guesses.

It seems likely that the probability of guessing correctly would be around 1/9, since people rarely pick the same number, but is a sustained 1/8 or better really possible?
