You don’t often hear about a company that wears its atheism on its sleeve — or its shoes. Atheist Shoes, however, is a German company that claims to make very comfortable shoes “for people who don’t believe in god(s)”.
According to their website, they noticed that packages sent to the U.S. were having a lot of delivery problems. So they devised an experiment, mailing two packages to the same address, with “Atheist” clearly printed on one and not the other.
The results were or were not surprising, depending on your understanding of Americans and religion (and maybe the U.S. Post Office). You can see the results on their website, which is worth visiting just to see how they tell the story (apparently they are artists in addition to being atheists — and someone there also writes very good English).
P.S. — If you scroll way down the page, there’s an epilogue that discusses the results of their study and its scientific aspects.
P.P.S. — This is also good:
