(Note: This show originally aired back in October.) On this edition of StudioTulsa, we speak with Dr. John Bargh, a social psychologist at Yale who's widely seen as a leading expert on the unconscious mind. He joins us to discuss his new book, "Before You Know It: The Unconscious Reasons We Do What We Do." As was noted of this volume in a starred review in Library Journal: "Although the work [in this book] is girded with years of studies and research, humor and use of personal anecdotes keep the writing accessible. Readers will finish the final chapter...with new understanding of the authority of the unconscious but also armed with practical tips, based on that knowledge, to use free will to change themselves. Readers of Angela Duckworth's 'Grit' or Malcolm Gladwell's 'Blink' will definitely want to read this, as will anyone seriously interested in psychology and self-improvement."
