Infinite scrolling. Push notifications. Autoplay. Our devices and apps were designed to keep us engaged and looking for as long as possible. Now, we’ve woken up from years on social media and our phones to discover we've been manipulated by unaccountable powers using persuasive psychological tricks. But this isn’t the first time.

In this three-part series from our colleagues at The Stakes, a look at the winding story of the science of persuasion — and our collective reaction to it. In part one, a once-famous psychologist who became embroiled in controversy, and how the Unabomber tried to kill him. 

We hear from:

- Larry Stern, Professor of Sociology at Collin College

- Nicklaus Suino, writer, martial arts expert, attorney and business consultant
