My rating: 7/10
An introduction to critical thinking, by Brian Dunning. He debunks many popular myths, or gives you the thinking tools to notice when you could be being conned. He looks at common scams such as psychic phenomena and health supplements. I’m not sure that everything he thinks is bogus actually is, but he is quite right to emphasise the need for hard evidence to help with making your mind up.
