Brad Wright, a professor of sociology at the University of Connecticut, recently wrote an article that appeared in ChristianityToday about an experiment in resumes. (This study was also mentioned in the Huffington Post). This experiment involved sending out resumes with very similar education/experience qualifications but vastly religious affiliations. The result of the study? Mentioning a religious affiliation (e.g. involvement in a religious college club) will decrease chances of a callback from a potential employer, particularly if it's a Muslim affiliation.
Religious discrimination still exists in the land of the free. And it's not just against Christians. Muslims and even atheists (ironically) also wrongfully suffer from religious discrimination.
