In today's episode, I spoke with Spencer Greenberg about the personality differences between men and women, the different intrinsic values liberals and conservatives find most meaningful, power-posing, and social-science reform efforts. Spencer is a mathematician and entrepreneur, as well as s the founder of Spark Wave, a "startup foundry" which creates software designed to help solve problems in the world using social science, and to accelerate and improve social-science research. He also founded [ClearerThinking.org](ClearerThinking.org), which offers free tools and training programs geared at improving decision-making, increasing positive behaviors, and reducing cognitive biases. Spencer has a PhD in applied mathematics from NYU, with a specialty in machine learning, and his work has been featured in media outlets like the Wall Street Journal, the Independent, Lifehacker, Gizmodo, Fast Company, and the Financial Times.
