@dlowan,
I've skimmed most of the article and what comes to mind as a psychologist-turned-philosopher is much of such "research" is based on anthropocentric concerns such as " Is
morality ( a human abstraction with religious connections) rooted in "nature" or "nurture"? Clearly Dawkins (et al) has made attempts to account for morality in terms of " an altruism gene", which is a direct challenge to religionists who see "morality" as the ultimate evidence for " a divinity". The academic psychologist, wearing blinkers , holds such controversial poles at arm's length and mistakenly assumes his data gathering is "an objective exercise". However, data gathering is
never objective...witness the furore over correlations of "race" and "intelligence".
We need to bear such anthropocentric concerns in mind when reading such material.
