This course is part of the Learn25 collection. In this compelling series, renowned human behavior experts Roy Baumeister and Dianne Tice unravel the mysteries surrounding one of humanity's most talked about but least understood forms of social interaction: sex. Playing the objective role of alien scientists observing human beings from outer space, they find patterns, puzzles, and paradoxes in how we make sexual decisions. Drawing on social psychology and even economics, they find new insights into age-old questions, such as these: -Do men really want to have sex more than women? -Who is actually having lots of sex, and why? -How has the internet changed sexual behavior? -Why have so many societies tried to stifle female sexuality? In nineteen eye-opening lectures, Drs. Tice and Baumeister delve into fascinating facts and findings to analyze human sexuality as a form of social interaction. While their discussions are strongly based on data about how most normal people make sexual decisions, they also explore larger issues about our sexual nature and motivations. This masterful course will answer all the questions you were afraid to ask and help you better understand human sexuality from a scientific vantage.
