Meta and Google trial: are infinite scroll and autoplay creating addicts?

Features woven into the fabric of platforms have been central to landmark social media harm case in US. How do they work?

It was as “easy as ABC”, claimed the lawyer prosecuting a landmark social media harm case against Meta and Google which heard closing arguments this week. The defendants were guilty, said Mark Lanier, of “addicting the brains of children”. Not true, replied the tech companies. Meta insisted providing young people with a “safer, healthier experience has always been core to our work”.

Features such as autoplay videos, infinite scrolling and constantly chirruping alerts woven into the fabric of online platforms were central to the six-week trial in Los Angeles, which has been compared to the cases against tobacco companies in the 1990s. But how do these features work and what are their consequences? Are they creating addicts rather than users or are they just giving consumers more of what they want?


Infinite scroll

There was a time when social media feeds ended. Now the scroll never stops. 

“There is always something more that will give you another dopamine hit that you react to and there is an infinite supply of that,” said Arturo Béjar, a whistleblower who worked in child online safety at Meta until 2021. “The promise of these things is that there is always going to be something interesting and rewarding and there is a never-ending supply. That is the mechanic of infinite scroll.” 

Internal documents surfaced in the trial showed that other Meta employees were worried about signs of rising “reward tolerance” among users. One email conversation in 2020 showed one person referring to Instagram saying: “Oh my gosh y’all IG is a drug.” A colleague responds: “Lol, I mean, all social media. We’re basically pushers.”

Béjar told the Guardian: “You are constantly chasing and even when you find what you are chasing … there is the promise of something else that catches your attention right after and with no bounds on that part of the mechanism.” 

Sonia Livingstone, a professor of social psychology at the London School of Economics said: “When you watch young people scroll through their feed, they flip really, really fast. They make split-second decisions to swipe, swipe, swipe, swipe, watch, swipe, swipe, watch. There is always a feeling that the next thing could be good and it’s only going to be another second or two.”


Autoplay

Jurors in the case against Meta and Google in Los Angeles began their deliberations on Friday. Their verdict will be closely watched as it could redefine tech companies’ responsibilities for their platform design.
