As evolutionary human scientists, we care about causality. We usually want to know whether something causes something else, rather than whether things are just correlated. We want to know whether aspects of our culture, social structure or ecology cause a given behaviour, as opposed to being merely associated with it, for instance. Experiments are the gold standard for assessing causality, but for obvious reasons cannot answer everything, especially many of the evolutionary questions we’re interested in – Randomising infants to be raised as religious or not, for instance, would be both impossible and ethically questionable (to put it mildly!).
