The “brightness” of the 15 percent might or might not indicate a profound feeling for the causes of things; it is largely verbal and symbol-manipulating, and is almost certainly partly an obsessional device not to know and touch risky matter, just as Freud long ago pointed out that the nagging questions of small children are a substitute for asking the forbidden questions.
The behaviourist motto is "cure the symptoms and you have eliminated the neurosis." Consequently, the behaviour therapist's approach is straightforward. He deals with definite complaints of patients such as fears of certain situations, tics, or obsessional thoughts, which are considered by him to be bad habits. His remedy for them is to use definite and explicit retraining procedures.
