This is wrong and you do many people a disservice who might read this and think it doesn't work. I don't know where you're getting this and the article in no way supports your stance. From the article:

Engaging in a course of well-tested psychotherapy, according to the new analysis, gives them an added 20 percent chance of achieving an even more satisfying improvement, or lasting recovery.

An added 20 percent chance.

Don't forget they're already saying that talking therapy is only 25% less effective than originally thought. They are still saying that talking therapy is effective! And at no point do they compare it to placebo.

The very article we're talking about:

1) Disagrees with your extremist stance

2) Never mentions it nearing placebo level

3) You probably didn't read it as you didn't address it

CBT, for example, is known to be particularly effective when dealing with anxiety as well as dealing with secondary symptoms and making people's lives better. It has an effect WAY above placebo.

So why did you say this? Are you actively attempting to make people's lives worse by putting them off therapy?

Also from the article:

for those who do well or fully recover, “psychotherapy, particularly cognitive behavior therapy, seems to be most effective in cutting the risk for a relapse long-term,” Dr. Hollon [one of the co-authors] said.
