Yes, I've been awful at updating LJ lately. Still, an amusing link from the Intarweb.
http://www.apa.org/journals/features/psp7761121.pdf In 1995, McArthur Wheeler walked into two Pittsburgh banks and robbed them in broad daylight, with no visible attempt at disguise. He was arrested later that night, less than an hour after videotapes of him taken from surveillance cameras were broadcast on the 11 o'clock news. When police later showed him the surveillance tapes, Mr. Wheeler stared in incredulity. "But I wore the juice," he mumbled. Apparently, Mr. Wheeler was under the impression that rubbing one's face with lemon juice rendered it invisible to videotape cameras ( Fuocco, 1996 ).
Everyone loves psychological studies, especially ones that confirm what we've long suspected!
