This is a podcast about deciphering human behavior and understanding why people do the things they do. I, Zach Elwood, talk with people from a wide range of fields about how they make sense of human behavior and psychology. I’ve talked to jury consultants, interrogation professionals, behavior researchers, sports analysts, professional poker players, to name a few. There are more than 135 episodes, many of them quite good (although some say I’m biased). To learn more, go to PeopleWhoReadPeople.com.
What actually makes negotiations work—and why do so many “tough” tactics backfire? In this episode, Zach talks with professional negotiator Andres Lares about why the most effective deals rarely come from trying to win at all costs. Drawing from sports contracts, Fortune 500 negotiations, and decades of real-world experience, Andres explains the “power of nice,” the importance of looking for creative win-win approaches, and why public posturing can kill agreements. They also dig into the hype around body language—what’s useful, what’s overblown, and what actually matters when you’re trying to read and influence people in the real world. Andres also talks about his views on AI-assisted sales-presentation-analysis programs (like Gong and Chorus). We also talk about the realism, or lack of it, in the movie Jerry McGuire. Andres is the CEO and Managing Partner of Shapiro Negotiations Institute (SNI), and the co-author of “Persuade: The 4-Step Process to Influence People and Decisions.”
