One famous example of reducing friction was the invention of infinite scroll. When trying to view results from a search, or look through social media posts, you could only view a few at a time, and to see more you had to press a button to see the next “page” of results. This is how both Google search and Amazon search work at the time this is written. In 2006, Aza Raskin invented infinite scroll, where you can scroll to the bottom of the current results, and new results will get automatically filled in below. Most social media sites now use this, so you can then scroll forever and never hit an obstacle or friction as you endlessly look at social media posts. Aza Raskin regrets what infinite scroll has done to make it harder for users to break away from looking at social media sites.
Infinite scrolling removes the "stopping point" from the interface, changing not the functionality itself, but people's behavioral rhythm and self-control costs. It makes continuing to consume content the default option, thus treating attention as an extractable resource, which is a classic example of "design as governance."
