Personally, this seems like an out of touch definition akin to Gen Z’s version of “dirty laundry”. When I first began to see doomscrolling appear in the digital vernacular it was almost exclusively in reference to scrolling with no end in sight, mindless scrolling, wasting inordinate amounts of time scrolling, etc. with no reference to the tone or themes of content consumed other than that it was short-form and ultimately unfulfilling.
But that is exactly how I expect a dictionary definition of a relatively new and tonally ambiguous term to present itself.
The definition listed online in dictionaries reads as though it was defined by someone who did not really know what “doom scrolling” was - they understood what “doom” and “scrolling” were independently, so they made the claim that the “doom” in doom scrolling had to do with the themes and tone of the content, where in my experience online the “doom” in doom scrolling actually represents then endless and mindless consumption of vapid content. Existing in a state of mindless repetitive dopamine scrolls equivalent with being “doomed”, the stagnation of other pursuits for the nothingness of scrolling, I could go on. This is all my opinion of course.
I think the proper definition for doom scrolling has been mentioned multiple times by others in this thread and it would be something like:
Rapid consumption of mobile short form content for extended periods of time, often with no end goal in mind.
Others have done better than me, but that’s my two cents.
