Let's take something like antidepressant medications. There's decent science saying it has an effect, but it's shockingly small after you control for penetration of the blind, people knowing that they're getting the active pills versus sugar pills, if you use an active control. It's probably only a few points. But it's a multi, multibillion-dollar industry. And by the way, has huge side effects. 40 percent of the people taking them have significant sexual side effects. And that's just one. A single antidepressant medication can be worth a billion dollars to a company.
The prescribers very often overstate, oversell, and the detail people are only too happy to tell them to do that. This idea that there's something wrong with your brain, and by the way, almost never are these antidepressant medications evaluated with what will happen if you're on them for three, four, five, 10, 15 years. Sometimes some of the side effects that come up come up only later, and sometimes they're very severe, even irreversible side effects.
In Scandinavia probably the most worker-supportive part of the planet, they have the highest rate of chronic pain and worker-related disability. So any kind of pain and difficulty is so much unwelcome that if you say that you're in pain, we're going to even pay you full salary to quit work because you're burned out, inside that what you're going to create is gigantic amounts of chronic pain syndrome. Scandinavians spend 15 percent of their gross national product on disability. 50 percent of the public health nurses are on disability. And that's where we're headed in the U.S. too.
It's pretty clear in how things are moving in empirically supported treatments that we're going to be speaking to the culture in a different voice. It's going to have some echoes of some of the deeper clinical and spiritual and religious traditions that had wisdom in it. If we're not going to get there through religious means and things of that kind, we're going to have to find a way to put it in the culture in a different way, because we need something right now other than yet another cable shoutcast or yet another Internet Web page showing us the cellulite on the actress's rear end.
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.
I want good science, and I want it to be realistically marketed. I wouldn't like only two countries on the planet that allow pharmaceutical companies to market directly to people, New Zealand and the United States. It ought to be better regulated. And when it's presented to people, it ought to be presented in a way that's realistic. For example, often people will prescribe antidepressant medications, and we'll say, you have a brain disease; you'll have to be on these medications permanently. There is no biological marker for depression. It's not true that we know that it's a brain disease.
When we fly planes over countries, dropping bombs on the evil ones, I think we're doing something very similar to what's being done when the infidels are getting their comeuppance with planes going into buildings. So it's gotten to the point where if we are not healthy psychologically as a human society, we will not have a planet to live on. And that's what keeps me up at night, when I see so little focus on the behavioral side of these problems, and the idea that just politics, or just physical science, is going to solve this.
