While mistyping my Google search terms, I found the similarly named mindhack.net, a site also concerned with tweaking the human mind.
Mindhack.net (in contrast to this site, mindhacks.com) relies solely on user contributions – sort of like a tradetricks.org for psychology.
Although it seems to have been a little quiet of late, it has plenty of fascinating material in its archives, and is undoubtedly an underused resource.
