CBT gets props because its empirical results have shown to be more effective than the traditional talk therapy approach. It's been around for a long time, has been studied enough for us to be confident that it makes a real difference, and I consider it as medicine for thoughts. Of course there's no way for us to quantify its precise method of action, so it's not that different than making the observation that the bark of a certain tree seems to reduce pain and inflammation, but if the burden of proof is to show direct causation from our thoughts and CBT to a better outlook on life, we might as well be asking about the nature of human consciousness.

CBT is a framework more than it is a manual, and not nearly as robotic as you've described. All therapy requires a human relationship to be successful. You have to trust your therapist to believe in the things they say, and that belief is a prerequisite for putting in the effort to reshape your thoughts and attitudes, but what's so robotic about a therapist asking you to explore the origin of a preconceived notion? About them asking you to be mindful of those type of thoughts? On coaching you to intercept those negative thought patterns and replace them with improved ones?

I think chalking up the efficacy of therapy to hope and placebo is a bit disingenuous. Yes, belief in change is a precursor to real change -- no therapist can help someone who isn't willing to believe or even want to change -- and in a way, the therapist's role is to guide you in your own endogenous healing process. However, there needs to be some rigor in the way they guide you to break bad patterns and replace them with better ones.

In a way, the therapist's challenge is like inception: how can I plant something in someone else's head but make them feel like they came up with it themselves? I think most of us could look at someone with low self esteem and negative thoughts and tell them what's wrong and what they should say or do or believe instead. However, that process needs rigor, and one of the best tools in the toolbox is to increase someone's mindfulness, and one of the best ways to do that is CBT.

I think overall you're a bit dismissive of it as a shallow, robotic approach when really it's a simple, repeatable, controllable frontline intervention. It's not going to work for deep-seated issues, but I think of it as almost being a prerequisite before those deeper issues can be tackled. I am of course speaking from personal experience, in both myself and what I've observed with others.
