There are circuits in the brain that encourage "seeking" behavior:
"Dopamine causes you to want, desire, seek out, and search. It increases your general level of arousal and your goal-directed behavior. Dopamine makes you curious about ideas and fuels your searching for information."
Dr. Susan Weinschenk suggests a way to stop the neverending-scrolling loop — create a new conditioned response, a physical movement, that you do to sort of signal to the brain that "this is done".
This article suggests ways to "hack" your dopamine system to encourage productivity: 1) Record small accomplishments, 2) Share results with your team, 3) Stay on task with micro-deadlines, and 4) Focus on how great you’ll feel when your project is complete.
There IS a lot of recent academic literature about this, but I'm not qualified to judge their merits. Therefore, I'm really interested in credible science communicators who publish accessible summaries in the lay press.
