This is the worst kind of pop psychology ‘reporting’ there is.

When will these myths finally die!? *sigh*

There is no scientific evidence to support the hypothesis that 'porn addiction' is a phenomenon. Likewise, sex addiction, videogames addiction, social media addiction ... and all the rest.

Furthermore, there is not merely no evidence to support the concept of an addictive personality type ... it is not even possible to relate the two concepts in any meaningful way; the idea of psychological addiction being the result of reifying the nebulous concept of 'personality' into the physiological realm of neurobiology/neurochemisty — the kind of reasoning evidenced by children on the cusp between the pre-operational. and concrete operational stages of development.

Finally, whilst there is a mechanism to the madness described here, resulting in a 'flood of dopamine' upon seeing porn (for the first or ten billionth time) ... it has nothing whatsoever to do with it being a 'reward'. The dopamine system is not a reward system, it's a difference engine — as it happens, there's a very good summary (readily understandable by the layperson) here: https://medium.com/the-spike/the-crimes-against-dopamine-b82b082d5f3d

These kinds of articles are the scourge of the discipline ... along with concepts such as "we only use 10% of our brain", "schizophrenics have split personalities" and many more besides ¹.

They are not only not helpful but are actively harmful, egregiously misinforming people about things ... please do not add to them
