In a recent experiment, 82 undergrads, all self-described Christians, filed in for a test that researchers billed as a handwriting personality assessment.
First, though, the test-takers were offered a drink, a very diluted lemon-flavored glass of water, and asked to rate its sweetness, sourness, bitterness, and disgusting-ness. Then, they were asked to copy a short passage from either the Bible, The God Delusion, the Quran, or the dictionary. Finally, they were given another drink, which was supposedly different (but actually the same exact flavor).
What's remarkable is that the students found that second drink of lemony water tasted more disgusting after reading about Islam or atheism, according to Miller-McCune's Tom Jacobs report on the paper “Gross Gods and Icky Atheism," suggesting a link between moral taste and our literal taste taste.
