Your personality is the set of basic traits that makes you you, influencing your habits of thought and behaviour. But how fixed are they? The great American psychologist William James said that our personality is set like plaster by age 30. But new findings show that while there is a degree of stability in our traits, we also continue to change in meaningful ways through our lives – our personalities are more like plastic than plaster.

In this talk, psychologist and author Dr Christian Jarrett will explore the pros and cons of the main personality traits, the role they play in shaping our lives, how your traits are likely to change as you age and in response to different experiences. But we don’t have to be passive: you’ll also discover evidence-based ways that you can deliberately change your personality.
