Yeah, it is the same reason why people believe other people that they are hungry because they feel hungry. The mechanism usually works unless the person is eating too much, then the scientists look into the mechanism of hunger. Similarly, scientists also look into someone's desire to be the other gender if they want to go under surgery.
teachings of the Bible are so muddled and self-contradictory that it was possible for Christians to happily burn heretics alive for five long centuries. It was even possible for the most venerated patriarchs of the Church, like St. Augustine and St. Thomas Aquinas, to conclude that heretics should be tortured (Augustine) or killed outright (Aquinas). Martin Luther and John Calvin advocated the wholesale murder of heretics, apostates, Jews, and witches. - Sam Harris, "Letter To A Christian Nation"
