What is Pull-to-Refresh?
Pulling down and waiting to see what new content appears works like a slot machine lever: the reward is unpredictable, which is what makes the gesture habit-forming.

Exploits variable ratio reinforcement: rewards that arrive unpredictably create stronger habits than rewards that arrive every time.
How to resist it
Check content at scheduled times instead of refreshing repeatedly for new updates.
