Thinking That We Know

Talk by Nobel Prize winner Daniel Kahneman on May 21, 2012 in Washington DC at the National Academy of Sciences, concerning how the mind filters and shapes information:

        Thinking That We Know by Daniel Kahneman

He discusses how scientists and non-scientists differ in what it means to know and believe something and how that relates to the challenge of communicating science to the general public:
Other communities have very different views about what it means to know and to believe. So for example for scientists believing unlike knowing does not carry a guarantee of truth. But this is certainly not true for true believers. True believers believe what they believe is true. They know it. They have a different conception of what knowing is. And for them the guarantee of truth is revelation and faithful transmission. And that is sufficient. It's just a different way of knowing.

And from their point of view, not ours, but from their point of view, science is just another religion, with its own rituals and its own claims and like all other religions it's false or it could be false, or there's certainly no guarantee that it is true. So we have to recognize that the definition of knowledge is contested and we have to take that into account, I think, in trying to communicate science to people who do not accept our definition or our concept.
