I wouldn't be surprised if there is something to it, but I suspected they didn't use legitimate coin flips (because it seems like a large amount of people can't really flip a coin), and looking at the videos confirms it, at least for the flips done by Bartos:

They're very low RPM and very low time in the air. Nothing I would accept for any decision worth flipping a coin for.

That's the "the video", that's a video by a third party about the study, and it doesn't include all footage or all participants.

The comment you replied to links to footage of one of the participants. You can see in that footage that the coin hardly leaves his hand.
