At IBCSR, we assume that religion is informed by both biological and cultural factors. This means that any theory of religion that leaves out biology or culture will be partial at best, and downright misleading at worst. In emphasizing a bio-cultural approach to the study of religion, we are tackling a longstanding problem in the contemporary academy: many social scientists are suspicious of biological reductionism, while biologists and neuroscientists are often dismissive of culture. We think both these positions are too one-sided, and so we call for détente in this decades-long battle between nature and nurture. We lead by example, which means we have to be aggressively and rigorously balanced. At IBCSR, we affirm that biology is real – humans are not blank slates. But we also highlight that culture’s influence is enormous and pervasive, and that almost nothing in religion reduces to mere biology. In fact, in the real world, biology and culture mutually influence and are influenced by each other in an endless feedback cycle.
