🧐 Introduction to the Art of Liespotting
The speaker begins by humorously highlighting the prevalence of lying in everyday life, setting the stage for a deeper exploration into the nature of deception. She introduces herself as the author of 'Liespotting,' and shares the impact it has had on her personal interactions. The speaker clarifies that the goal is not to play a game of 'Gotcha' but to understand the cooperative act of lying and to use scientific knowledge to spot deception. She emphasizes that lying is a choice both the liar and the one being lied to make, and that not all lies are harmful. The societal costs of deception, such as corporate fraud and betrayal of trust, are discussed, along with the importance of seeking truth and building trust.
🤔 The Complexity and Evolutionary Value of Lying
This paragraph delves into the complexities of lying, its integration into our daily lives, and our ambivalence towards truth. The speaker discusses the societal acceptance of certain lies and the historical context of deception. She explores the evolutionary advantage that intelligence and deception provide to species, using examples from literature and real-life instances of deception. The development of deception skills from childhood to adulthood is outlined, and the speaker challenges the audience to navigate the 'post-truth society' by becoming trained liespotters, who can accurately detect deception 90% of the time, compared to the general population's 54% accuracy.
🕵️♂️ Identifying Deception through Speech and Body Language

She provides examples of verbal cues that may indicate lying, such as non-contracted denial, use of distancing language, and qualifying language.
