I use meta-placebo effect instead of medicines.

I know that the placebo effect exists and is effective, so believing something can heal me will indeed heal me.
Therefore, I juste have to believe that just believing that believing will heal me will heal me, and it heals me.

To be useful, the system still needs to be able to tell whether a single user password is correct (and needs to do so reasonably efficiently). So if someone has a 6 character password (which is dumb) you can just try all possible passwords (there isn't that many possible 6 realistic character passwords). Either lots of them work (which would a problem) or you found the password.

No, as I understand it from the article, you can't tell if a single user password is correct, because you don't have a measure for "correct"-- all that you check whether that password points to the same place (in a multidimensional phase space) that other passwords project to. (It does seems to only work is you can assuming that all, or at least "most," of the other passwords people enter are correct).

So... how do you know if a user can log in? You have to wait until a bunch of users want to log in simultaneously?
