There's still a difference between "guessing" correctly versus actually knowing the truth. It's different from an actually unblinded study even if participants

  Looks to be a vanishingly small difference if they guessed correctly, the first time they were asked, 94.7% of the time with 90% confidence.

    In order to understand the difference, you'd have to have a blinded and unblinded study, and compare the results. Then you could understand the difference between a guess with 90% confidence and actually knowing what treatment you received with certainty. It seems reckless to presume the difference (between blinded and unblinded) is small. The numbers you cite (94.7% and 90% confidence) have nothing to do with the question you're trying to answer. For example, an important difference may be with respect to expectations. If you're told you're receiving a psychedelic treatment, you may go into the experience with different expectations than if you were unsure about what treatment you were getting.
