Previously in this thread I opined as follows on the state of the art in self help: there are enough gullible prospective clients that it is never in the financial self-interest of any practitioner to do the hard long work to collect evidence that would sway a non-guillible client.

PJ Eby took exception as follows:

you ignored the part where I just gave somebody a pointer to somebody else's work that they could download for free

Lots of people offer pointers to somebody else's writings. Most of those people do not know enough about how to produce lasting useful psychological change to know when a document or an author is actually worth the reader's while. IMHO almost all the writings on the net about producing lasting useful psychological change are not worth the reader's while.

In the future, I will write "lasting change" when I mean "lasting useful psychological change".

you indirectly accused me of being more interested in financial incentives than results

The mere fact that you are human makes it much more probable than not that you are more skilled at self-deception and deception than at perceiving correctly the intrapersonal and interpersonal truths necessary to produce lasting change in another human being. Let us call the probability I just referred to "probability D". (The D stands for deception.)

You have written (in a response to Eliezer) that you usually charge clients a couple of hundred dollars an hour.

The financial success of your self-help practice is not significant evidence that you can produce lasting change in clients because again there is a plentiful supply of gullible self-help clients with money.

The fact that you use hypnotic techniques on clients and write a lot about hypnosis raises probability D significantly because hypnotic techniques rely on the natural human machinery for negotiating who is dominant and who is submissive or the natural human machinery for deciding who will be the leader of the hunting party. Putting the client into a submissive or compliant state of mind probably helps a practitioner quite a bit to persuade the client to believe falsely that lasting change has been produced. You have presented no evidence or argument -- nor am I aware of any evidence or argument -- that putting the client into a submissive or compliant state helps a practitioner producing lasting change. Consequently, your reliance on and interest in hypnotic techniques significantly raises probability D.

Parenthetically, I do not claim that I know for sure that you are producing false beliefs rather than producing lasting change. It is just that you have not raised the probability I assign to your being able to produce lasting change high enough to justify my choosing to chase a pointer you gave into the literature or high enough for me to stop wishing that you would stop writing about how to produce lasting change in another human being on this site.

Parenthetically, I do not claim that your deception, if indeed that is what it is, is conscious or intentional. Most self-help and mental-health practitioners deceive because they are self-deceived on the same point.

You believe and are fond of repeating that a major reason for the failure of some of the techniques you use is a refusal by the client to believe that the technique can work. Exhorting the client to refrain from scepticism or pessimism is like hypnosis in that it strongly tends to put the client in a submissive or compliant state of mind, which again significantly raises probability D.

To the best of my knowledge (maybe you can correct me here) you have never described on this site an instance where you used a reliable means to verify that you had produced a lasting change. When you believe for example that you have produced a lasting improvement in a male client's ability to pick up women in bars, have you ever actually accompanied the client to a bar and observed how long it takes the client to achieve some objectively-valid sign of success (such as getting the woman's phone number or getting the woman to follow the client out to his car)?

In your extensive writings on this site, I can recall no instance where you describe your verifying your impression that you have created a lasting change in a client using reliable means. Rather, you have described only unreliable means, namely, your perceptions of the mental and the social environment and reports from clients about their perceptions of the mental and the social environment. That drastically raises probability D. Of course, you can bring probability D right back down again, and more, by describing instances where you have used reliable means to verify your impression that you have created a lasting change.

For readers who want to read more, here are two of Eliezer's sceptical responses to PJ Eby: [001][1], [002][2]

If it makes you feel any better, I am not seeing you any more harshly than I see any other self-help, life-coach or mental-health practitioner, including those with PhDs in psychology and MDs in psychiatry and those with prestigious academic appointments. In my book, until I see very strong evidence to the contrary, every mental-health practitioner and self-help practitioner is with high probability deluded except those that constantly remind themselves of how little they know.

Actually there is one way in which I resent you more than I resent other self-help, life-coach or mental-health practitioners: the other ones do not bring their false beliefs or rather their most-probably-false not-sufficiently-verified beliefs to my favorite place to read about the mental environment and the social environment. I worry that your copious writings on this site will discourage contributions from those who have constructed their causal model of mental and social reality more carefully.
