The headline "porn causes depression" collapses a distinction the research is careful to keep.
Problematic pornography use tracks distress better than overall frequency does. Studies that separate high-frequency users with no distress from high-frequency users with impaired control and distress find that the two groups differ, and it is the problematic group that scores worse on depressive symptoms and self-esteem. Frequency on its own does not predict the difference.
Two things follow. First, the population average is not you: if your use is frequent but controlled and not costing you anything, the depression finding is not about your group. Second, if your use is out of control and you are low, the two are keeping company, and the direction of travel is not established. Low mood can drive the behaviour as readily as the behaviour can drive low mood.
The practical reading is the one the course gives for the flatline: a dip in mood during a change of habits is one thing; two weeks of not caring about anything is depression in its own right, and it wants a GP, not a streak counter or a forum.

- Well establishedProblematic pornography use tracks distress better than overall frequency of use does. People who use frequently without distress and people who use frequently with it are distinguishable, and it is the problematic group that differs on mental-health measures - most clearly on depressive symptoms and self-esteem.Bothe et al. 2020, J Sex Med 17(4):793-811, doi:10.1016/j.jsxm.2020.01.007
- Well establishedFrequency of use alone is a poor indicator of problematic use. Distress, impaired control and functional impairment are what distinguish it.Bőthe et al. 2018, 2020; ICD-11 CSBD criteria
