The research on the effects of therapy continually demonstrates that the relationship between patient and therapist is much more important than the "brand" of therapy, that the personal qualities of the therapist are far more relevant to the success of the treatment than his or her theoretical orientation. There also appears to be temperamental differences among patients that suit them more toward one kind of treatment than another. Analytic, depth therapies tend to be a good fit with people who are curious, who like to figure things out for themselves, who have some tolerance for ambiguity, who are comfortable with emotion, and who have some intuitive sense that there are unconscious processes within the human psyche.
