Martin gave us a lively overview of the biases we are all subject to, however much we’d like to think otherwise, and how it’s all too easy for people to find themselves committed to false beliefs, despite the evidence against them. The talk was followed by a Q&A where we were able explore the topic further.  It was good to see so many there for this reboot of Plymouth Skeptics in the Pub – at least thirty people attended.

Here are some links related to the talk. First the books he recommended:
