fish waffle writes "Suspecting that their strongly branded "Athiest" products may be treated differently by more religiously-oriented postal regions, Kickstarter success Athiest Shoes conducted an experiment. They sent 178 envelopes to 89 people in different parts of the US, each person receiving one envelope prominently branded as "Athiest" merchandise, and one not. The results: packages with the athiest label were nearly 10 times more likely to never be received, and took on average 3 days longer to show up when they did. Control experiments were also done in Europe and Germany---it's definitely a USPS problem."
