First of all let me just say this. I don't think I said we will be making better decisions; I think I said I hope we will.
I actually agree with what you said. I think we can become overwhelmed by information and data, and that would be a bad thing. Part of what I wanted to emphasize with regard to the importance of open dialogue is that if we don't talk these things through about how we organize the data, how we use it, how we understand it, how we interpret it, then we're at risk of having so much of it with no real coherence to it that we don't know what counts and what doesn't. So part of my argument would be that it's one of the reasons we need dialogue, so we can understand and agree, at least on some levels, as to what it means to say this is about poverty or about financial success or some other thing.
The last thing I want to say is that I absolutely agree with the last thing you said about vision and so on. I don't ever want to live in a world that is run by nothing but scientific policy. I've railed against that all my life.
Here's what I would say. Big policy issues are a complex mix of information, knowledge, and choices. Choices are about values and priorities and lifestyle and all that. I don't want to lose that for a moment.
I think what we don't want to do, on the other hand, is decide that everything is just about priorities and values. It actually isn't. We do know some things about the world, and if we knew things about the environment, about the social environment, about business development, and about a whole range of other issues, those would inform our policy-making.
What I want to argue is that we have a chance to advance policy-making beyond where it ever was. That's not to say it's just about science. It will never be that way.
So I don't think we disagree at all.
