The addictive personality myth is a psychological theory based on the idea that a lot of people are addicted to more than one thing and that some people have a proclivity to be addicted to things more than others.
The evidence for the addictive personality theory is not strong. And, once you understand the emotional basis of addiction, it becomes clear that this theory doesn't really hold any water. The reaosn why so many people get addicted to more than one thing is because addiction, at its core, is an emotional problem. It is not a personality issue, it is an emotional avoidance issue.
