Supposedly, people are less likely to steal when they're feeling watched. Even if they're being watched by eyes printed on a piece of paper. I have no substantiation of this, as even with my mastery of the Google search, I couldn't find the article I'd read.
Nevertheless, being the intrepid experimentalist, I moved forward with my own 'all seeing eye' study, watching for the perpetrators of the massive theft of Sweet-n-Low, sugar and non-dairy creamer from our breakroom.
We shall see if this has any effect, and I will report my findings to you, my esteemed readers.
