I haven't read the article, but from what you described, it sounds like an endorsement by the self-help, positive thinking community, which believes that brainwashing ourselves with positive thoughts will cure everything. Well, it doesn't work that way, despite what they think their research has proven. Unfortunately, many of today's cognitive behavioral therapists believe in the same concept.

The reality is that many people suffer with deep emotional wounds and other issues that cannot be resolved by changing one's thought patterns. The original damage or issues were not thought into existence and thus cannot be thought out of existence. This is a very simple truth that is too frequently not understood by today's psychology professionals and others.
