If you think that you are rational and unprejudiced, Michael Blastland hopes you will be open minded enough to listen to the evidence which suggests that you are probably not.

We might think our views about global warming, nanotechnology or the value of IQ tests are based on scientific evidence. But the beliefs we hold about these issues often say more about our ability to screen out the evidence we dislike than it does about the scientific facts.

Michael Blastland investigates the causes of our cognitive biases and our remarkable ability to not let the facts get in the way of a deeply held belief.
