Why is my friend late? How does nuclear fission work? What can I do to help my baby sleep through the night? We all feel the need to understand why certain things happen. Some researchers think the drive to explain the world is a basic human impulse, similar to thirst or hunger.

Then, Jonathan Rottenberg answers your questions about rethinking depression on Your Questions Answered.

He also offers ways to better understand these forces and lessen their power over us.

Think about the last time you had a discouraging thought. Maybe you told yourself, "This won't work. I'm not cut out for this." Did you take that thought as fact? Last week, we talked with psychologist Martin Seligman about why some people come to believe that their actions don’t matter. In the second part of our conversation, he explains how we can strengthen our sense of agency, learn to see new possibilities, and build confidence in our ability to shape what happens next.
