Although this book deals with the conflict between religion and science, I see this as only one battle in a wider war—a war between rationality and s… - Jerry Coyne

So if morality is innate, it’s certainly malleable.

Theists’ typical response to these failures (i. e., of prayer to affect rates of healing) is to say either “God won’t let himself be tested” or “That’s not what prayer is about: it’s simply a way to converse with God.” But you can bet that had these studies shown a large positive effect, the religious would be noisily flaunting this as evidence for God. The confirmation bias shown by accepting positive results but explaining away negative ones is an important difference between science and religion.

But the God hypothesis for morality and altruism has its own problems. It fails, for example, to specify exactly which moral judgments were instilled in people by God and which, if any, might rest on secular reason. It doesn’t explain why slavery, torture, and disdain for women and strangers were considered proper behaviors not too long ago, but are now seen as immoral. For if anything is true, God-given morality should remain constant over time and space. In contrast, if morality reflects a malleable social veneer on an evolutionary base, it should change as society changes. And it has.
