This study explores the association between self-assigned religious affiliation (Christian, Muslim, and unaffiliated) and attitudes toward women’s rights among a sample of 1,058 students between the ages of 14 and 18 years in England and Wales, after taking into account personal factors, home environment factors, psychological factors, and religious factors. While religious saliency and interreligious openness both predicted a more positive attitude toward women’s rights, after taking these attitudinal factors into account self-assigned religious affiliation (both Christian and Muslim) predicted a less positive attitude toward women’s rights. This finding highlights the fallacy of discussing self-assigned religious affiliation independently of distinguishing the religious saliency of such affiliation
