Yesterday I read that Harvey Weinstein is checking into a facility for treatment of "sex addiction." Is repetitive sexual harassment or sexual assault a form of sex addiction?
Sex addiction, like any addiction, is a repetitive, compulsive behavior. The hallmark of any addictive behavior is that it is experienced as being outside of the person's control. A common self-test for addiction is to try to stop the behavior for a period of time. If you find that you are engaging in the behavior after you told yourself you wouldn't, this could be a sign of an addictive disorder. Simply making something a habit is not itself a sign of addiction. If the behavior is under the person's control, an addiction has not been established regardless of how dysfunctional the behavior is.
Sex addicts typically either frequent prostitutes, pick up random strangers for sex on a regular basis, or spend hours masturbating to online pornography. Some also compulsively attend peep shows and strip clubs. Eventually they start to realize that they are spending enormous amounts of time or money (or both) on their sexual activities, and perhaps endangering their health or even their lives. At this point an addiction has been established, and sometimes, people seek help.
Based on the publicly reported evidence, Weinstein appears to have exercised great control and planning in his harassment activities. Subterfuge and the assistance of allies appear to have been involved in the various scenarios that have been reported. The cost of hiding the behavior appears to have been calculated. This type of planning and execution is rare in addictive behaviors, because, as I said, the hallmark of addiction is that the behavior has spun out of control. In addition, on a deeper psychological level, addiction is about a regression in which the person unconsciously grants power to a substance or behavior, enacting a dominance/submission dynamic in which the addict is the submissive. In Weinstein's case, it's obvious that the dynamic went the other way in his encounters with young actresses and models.
If it's not an addictive disorder, is it possible that Weinstein has a different clinical disorder? It's possible and perhaps likely, but it may be one that it is extremely difficult to treat. Pleasure in exercising control and dominance over others is sadism, a psychological phenomenon that is rarely treated because sadists don't seek help. I'm not aware of any standard treatment protocols for sadism except perhaps psychoanalytic therapy to resolve early childhood traumas and conflicts, but, as sadists are rarely interested in such treatment, there isn't a lot of evidence regarding outcomes. Sadism is often a component of antisocial personality disorder (also called sociopathy or psychopathy) and this disorder is notoriously difficult to treat. Confrontation and limit-setting may be the only ways to address sociopathic behavior. People, like other animals, respond to negative consequences for behavior.
