The book "Magic Words: What to Say to Get Your Way" by Jonah Berger explores how subtle changes in language can have a significant impact on our interactions with others, influencing everything from our personal relationships and career success to broader societal biases. Berger examines six categories of "magic words" - words that activate identity and agency, convey confidence, ask the right questions, leverage concreteness, employ emotion, and reveal underlying societal structures. He uses data from numerous studies and real-world examples to demonstrate how manipulating the way we speak can influence how we are perceived, the outcomes of conversations, and even our ability to predict future behavior.
