Stephen Downes

I like this video a lot. It gets at an important element of the scientific method (not the only element - the scientific menthod is much more complicated than one simple rule) and it also gets at why so many people reason poorly. In a nutshell: when we look for evidence, we very often look for evidence that confirms out theories, and that's often pretty easy to find. But the confirmation is an illusion. It's only when we try to find evidence that disproves our theories that we can know whether we're getting closer to the truth. Via ScienceDump.
