A Harvard Cognitive Scientist's Ultimate Guide to Rational Thinking
Stephen Pinker, a renowned Canadian cognitive psychologist and author, engages with Big Think on a wide range of topics such as human progress, the "tragedy of the commons," the Bayesian approach, and strategies for curbing our most destructive instincts with the goal of making the world a better place for all. At the core of Pinker's argumentation is the idea of rationality. In his 2023 book, Rationality: A Harvard Cognitive Scientist's Ultimate Guide to Rational Thinking What is it, why is it so rare, and why is it important?" Pinker explores the mysterious nature of human progress, wondering how we have managed to make so many impressive scientific breakthroughs while also being influenced by common irrational phenomena such as fake news and conspiracy theories. Pinker argues that humans are not inherently irrational, but rather that our thought processes are better suited to a low-tech environment. So how can we develop more rationality in today's complex world? Pinker believes that improving education is one of the key factors. By teaching children critical thinking skills, we can better prepare them to identify biases, emotional reasoning, and cognitive distortions. A more effective educational approach could focus on probability theory, persuasive rhetoric, and developing empathy by understanding the perspectives of people with different views. By fostering these skills, we can create a more rational and informed society that is better equipped to address the challenges of the modern era. 0:00 Meet Steven Pinker 0:25 Why does rationality matter? 3:44 How can we measure human progress? 10:17 Is your view of progress optimistic? 12:12 Are we a rational or an irrational species? 18:29 What are the current threats to rationality and progress? 23:41 Why do new technologies tend to increase irrational thinking? 26:05 How do institutions both enable and hinder progress? 29:57 How does cancel culture stifle rationality? 32:14 What are "tragedies of the commons" and how can they impede progress? 35:58 Do "tragedies of the commons" contribute to political polarization? 37:23 How can narrative thinking skew our perception of the world? 39:51 What are cognitive illusions and do they explain irrationality? 44:49 What is Bayesian reasoning? 50:34 What’s a situation where people tend to neglect Bayesian reasoning? 55:53 Why is Bayesian reasoning indispensable for scientists and AI researchers? 56:42 How useful is Bayesian logic for everyday reasoning? 59:25 Why is it so hard to get people to use Bayesian reasoning? 1:00:29 When can a focus on Bayesian reasoning become problematic? 1:04:20 Why do some journalists and scientists forego Bayesian reasoning? 1:08:22 Is the media responsible for our inability to employ Bayesian reasoning? 1:10:08 Can you simplify Bayes’ theorem for us? 1:10:59 Can we become more rational? 1:17:03 Do we have what it takes to be collectively more rational? About Steven Pinker: Steven Pinker is an experimental psychologist who conducts research in the fields of visual perception, psycholinguistics, and social relations. He grew up in Montreal, received his bachelor's degree from McGill University, and his doctoral degree from Harvard. He is currently a professor of psychology at Harvard and has also taught at Stanford and the Massachusetts Institute of Technology. He has received numerous awards for his research, teaching, and nine books, including Language as an Instinct, How the Mind Works, The Blank Slate, The Best Angels of Our Nature, The Sense of Style, and Enlightenment Today: Arguments for Reason, Science, Humanism, and Progress.
