My clients who have participated extensively in therapy or substance-abuse recovery programs sometimes sound like therapists themselves—and a few actually have been—as they adopt the terms of popular psychology or textbook theory. One client used to try to lure me into intellectual debates with comments such as, “Well, your group follows a cognitive-behavioral model, which has been shown to have limitations for addressing a problem as deep as this one.” An abusive man who is adept in the language of feelings can make his partner feel crazy by turning each argument into a therapy session in which he puts her reactions under a microscope and assigns himself the role of “helping” her. He may, for example, “explain” to her the emotional issues she needs to work through, or analyze her reasons for “mistakenly” believing that he is mistreating her.
