SEE BELOW FOR UPDATED CRITERION (MODS RESOLVE)

Resolves YES if there are independent reports from people who were in contact with George3d6 (I'm thinking of johnswentworth and jacobjacob from the comments from the post) and used his methodology that they found a significant increase in IQ. This will resolve YES if at least THREE people report a significant (not specifying exactly what significant means, but if is unclear, I will wait until further replication) increase using this method.

Resolves NO if George3d6's experiments indicate this is not replicable AND at LEAST three people report they have not found a significant increase using this method.

I'm not exactly sure if these resolution criteria are good, so if you have any suggestions, please put them in the comments and if I think there are better, I will update the resolution criteria. I will try to resolve this in the spirit of the answer rather than EXACTLY adhering to the resolution criteria if things seem unclear.

Edit: updated resolves no to be more strict. If it is unclear, I will just keep the question open until parties agree. If it seems that no one is going to agree (and people arrive at a sort of stalemate), I will resolve N/A

SECOND EDIT:

This market's resolution will be decided by site moderators. This overrides any resolution criteria above.
