I think very few, here or anywhere, would say that it can’t work. I think the big questions are 1. are they necessary to solve the problem and 2. how likely are they to solve the problem vs. other methods.
Unlike the science of medicine generally, psychology does not lend itself to hard rules well. Too many variables, choices, and each mind is unique in some way. Also, far too often, people in this field try to either subtly or overtly deny or minimize the idea of free choice. This makes me wary, as IMHO this is the worst and most depressing form of kefira that exists.
Bottom line: all methods must be on the table. Knowledgeable people should be consulted before embarking on a journey, particularly one that is long-term and/or changes brain chemistry. This includes experts on morality and free choice as well as experts in psychology.
