Rethinking Body Language: How Hand Movements Reveal Hidden Thoughts challenges traditional views on body language by presenting a new theoretical perspective based on cutting-edge research. Author Geoffrey Beattie argues that gestures reflect aspects of our thinking, distinct from verbal language. The book explores how spontaneous hand movements during speech often communicate more than intended and can be used to detect deception through gesture–speech mismatches. Written engagingly by one of the leading experts in the field, it offers insights into people’s underlying implicit attitudes, transforming the way we understand body language.
