ideas, innovations and apps for social work in the age of smartphones and social media

Earlier this week, in questioning the significance of a “scientists find internet-addiction gene” story, I conceded that the scientific study in question did find something interesting: A gene that seems to be (very modestly) correlated with internet addiction also plays a role in nicotine addiction.
Maybe this nicotine connection is what prompted the German scientist who was the lead author of the study to declare that, thanks to his work, we now know that “internet addiction is not a figment of our imagination.” After all, if a gene involved in a manifestly chemical addiction, like nicotine addiction, is also involved in something people doubt is literally an addiction, then that should remove the doubt, no?
No. Whether heavy internet use deserves to be called an addiction or just a hard-to-break habit is a question about a behavior pattern and its attendant psychological states. To answer it we ask such things as how strong the cravings for the internet are, what lengths a person will go to in order to satisfy them, and so on. But even if we decide, after answering such questions, that a given person’s internet dependence amounts only to a habit, and doesn’t warrant the “addiction” label, it still makes sense that genes which mediate chemical addictions–nicotine, cocaine, whatever–would be involved.
