Becky Ripley and Sophie Ward take a cold hard look at the psychology behind each of the seven deadly sins. Rolling with the order established by Pope Gregory the Great, first up is pride, followed by greed, lust, envy, gluttony, wrath, and (finally) lazy old sloth. Why have we evolved these ugly emotions? What’s going on in the brain and the body when we feel them? And how best can we live alongside them - in ourselves and with others?

Pride - also known as the "original sin" - is now a bit of a double-edged word. The good side is motivating and self-affirming: to be proud of your work, your kids, or your identity. But then there’s the ugly side of pride: thinking you’re better than others. Arrogance, narcissism, an inflated sense of superiority. How can we have one without the other? Confidence without arrogance? Self-worth without self-aggrandisement?

To guide us through this mess is evolutionary anthropologist Dr Anna Machin from the Department of Experimental Psychology at the University of Oxford, neuroscientist and clinical psychologist Professor Ian Robertson from the Department of Psychology at Trinity College Dublin, self-aware narcissist and motivational speaker Lee Hammock, Professor Jessica Tracy from the Department of Psychology at the University of British Columbia, and a parade of people at a Pride march.
