A lot of science doesn't require big "ns" but if you're trying to understand something about human health and you're looking at interventions that are not going to be either killing you or making you live forever - they're going to have some tweaking on the outcome - you need big numbers or you don't have enough power.

Science is... a powerful way, indeed - to study the natural world. Science is not particularly effective... in making commentary about the supernatural world. Both worlds, for me, are quite real and quite important. They are investigated in different ways. They coexist. They illuminate each other.

I'm enormously interested to see where neuroscience can take us in understanding these complexities of the human brain and how it works, but I do think there may be limits in terms of what science can tell us about what does good and evil mean anyway, and what are those concepts about?

When a drug comes out [that's broadly prescribed] there are going to start to be a lot of people on it [in a million person cohort] and you might get therefore an early signal of something unexpected that hadn't come through in the clinical trials. And I'm sure [drug companies] would love it if, in fact, FDA, recognizing that, would say, OK, maybe you don't have to do your trial with 30,000 people because we're going to find out shortly after registration because we'll have a lot of people taking the drug and we'll be able to see what happened using PMI.

I've never heard God speak out loud to me. That's not an experience I have had.

God is an awesome mathematician and physicist.

A lot of people think PMI is the genome project 2.0. No. This is about all the influences on disease - genetics is in there, but the environment is in there as well, health choices, behaviors, all the factors that are important, otherwise we're not doing what we promised we would do - which is in a holistic way look at how people stay healthy or how do they fall ill.
