I like tackling problems that I can see making an impact on real people and real businesses immediately.

We're pushing the limits of what a game is, and they think I'm beyond this limit. There will always be purists, but we've never got that push-back from businesses or consumers. Game dynamics are too powerful to leave bottled up in games.

I had a reputation in high school for making trouble.

Climate change is a complex problem with no central lever, and with unequal distribution of resources.

As soon as questions of will or decision or reason or choice of action arise, human science is at a loss.

I've written books as acts of discovery: things I need to know and that I need to touch. And it's very dangerous work to deal with the most toxic internal elements... I feel like Madame Curie at my computer. I feel like I should be hemorrhaging from my eyes and ears.

Science is based solely on doubt-based, disinterested examination of the natural and physical world. It is entirely independent of personal belief. There is a very important, fundamental concomitant - that is to accept absolutely nothing whatsoever, for which there is no evidence, as having any fundamental validity.

We have been talking about public engagement for a decade. For me it is about recognising that the mission of science has to be embedded within our culture - the direction in which science is going has to be determined by all of us, and so we need a dialogue with the public.
