There are scams in every arena. There are yeshivos that are scams. There are contractors that are scams. There are rabbonim, mechanchim, and menahalim that are scams. If you are the victim of a scam, you are apt to perceive all those as scammers. There are no numbers here, at least those collecte with an eye to reliability. In relaity, there are good and bad doctors, good and bad lawyers, and the same goes for every conceivable career. But maybe we should take a peek at some of situations that give the picture that all is not well with therapists.
Our community can boast many people engaging in therapy that are either undertrained or not trained at all. Their best intentions do not result in best outcomes.
We have those who practice outside of their areas of expertise. Example, child therapists require specific training. An adult therapist is unlikely to be knowledgeable enough about kids unless he/she has undergone such training.
The word trauma is widely used, and its definition has expanded over the years. Not every therapist is trained in many trauma related conditions. There are those that believe they are qualified when they are not. Keeping to one’s training is crucial, as well as a requirement in all professional ethics.
Therapists have many available modalities. Training varies, and one might be trained in some modalities but not others. It is critical that the recommendations for which modalities to use comes from the trained professional. The Rov who “prescribes” EFT, DBT, CBT, or other letters is likely to be poorly informed enough as to create confusion.
There are situations in which therapists opine about the conditions and diagnoses of people they have never evaluated or even met. This is grossly unethical. Rabbonim have had professional opinions brought before them by these “rogue” therapists, unable to recognize that these are baseless and incompetent conclusions by unethical professionals.
Therapists can be misused. It is not strange that they are asked to assist clients in so much of their decision making that it results in unhealthy dependency.
Therapists are humans, and thus able to make mistakes. Some our greatest leaders, Gedolei Yisroel, and more have made mistakes. The Torah tells us about mistakes made by Moshe Rabbeinu, Aharon Hakohen, and Miriam Haneviya. The Torah never generalized to all of Sheivet Levi to denounce them. And even Moshe, Aharon, and Miriam retained their respect and status. The broad brush used for branding by the OP is foolish, untrue, and misleading.
