Antidepressant medications, you still have some depressive thoughts. Antipsychotic medications, you still have some psychotic symptoms for the vast majority of the people taking them. But it gives them a little separation, and it doesn't control his behavior as much when you have a sad feeling, difficult thought, an odd perceptual experience. We can teach people those exact skills in therapy, you get longer-term benefits and without the side effects. So don't be sold just because a commercial interest wants to sell you things.

The mental cognitive processes that we're targeting are ones that narrow human beings' repertoire and make it harder for them to learn to be more flexible, to take advantage of the opportunities in front of them. We can have something to help with in areas like child development or organizations and schools, or maybe even how peoples interact with each other, one to the other. We've taken the work into things like prejudice and stigma, because if we can't solve that we have planes flying into buildings. So it applies broadly because anywhere that a human mind goes these processes go.

What keeps me up at night in a negative way is, if we don't solve the problems of the human heart and of the human head, of human psychology, there is no technological solution so great that it can prevent the world that is coming, and a world of suitcase bombs or of the ability to pollute the planet in a way that it cannot recover, of global warming and the rest. We've created through science and technology a different world that has frightening sides to it, and psychology and behavioral science has to be part of this. We're going to have to find a way to humanize the culture itself.

ACT psychology is a psychology of the normal. A lot of the psychologies that are out there are built on the psychology of the abnormal. We have all these syndromal boxes that we can put people in and so forth. The actual evidence on syndromes is not very good. There's no specific biological marker for any of the things that you see talked about in the media. Even things like schizophrenia - there's no specific and sensitive biological markers for these things. There may be some abnormal processes involved, but vastly more of human suffering comes from normal processes that run away from us.

I kind of look at what's on the T-shirts and I see another solution, which also worries me. I see "Just do it." "No fear." - this kind of suppressive response to the treacle that the culture tries to define for us as a meaningful life also blows up on you. "No fear" is not something that you should put on your shirt. How about "I can hold my fear and still connect with you"? Put that on your shirt. "It's okay to be me, with all of my history." Put that on your shirt.

If you aren't willing to have it, you will.

Our children are exposed to 10, 20, 30 times the number of words that our great-grandfathers were exposed to. We're exposed in a single day or two to more horror on our Internet Web pages than our great-grandfathers were exposed to in decades of living. We have not created modern minds for that modern world. Science and technology has just dumped it on us. And I think people yearn for it. I think you see it in what's popular. Why are people wanting to learn about meditation and talking about a purpose-driven life? It's because they know more is needed in the modern world.
