We were delighted that Discover Magazine wanted to feature an extract from Extreme. They suggested the section on personality and extreme environments from Chapter 12, and we think it makes a good standalone feature.

When considering extreme environments it is easy to make assumptions about personality, which on closer examination do not stand up to scrutiny. Take, for example, one of the best-researched personality dimensions: introversion-extraversion. Extraversion as a trait appears in all established psychological models of personality, and there is considerable evidence that it has a biological basis. The concepts of introversion and extraversion long ago escaped the confines of academic psychology and are widely used in everyday conversation, albeit in ways that do not always reflect the psychological definitions.
