Digital junk food: Social media algorithms designed to highlight controversy not science

Imagine that you have a very social friend — Rickie — who throws a potluck dinner every year. He asks every guest to bring a dish. But Rickie doesn’t want those guests to serve themselves. Instead, he makes lists of what he’ll serve to each person.

His parties have been so popular that they now draw hundreds of guests, all bringing different foods. And Rickie’s pleased. But now he can’t find the time to make them each a separate food-plating list.

Rickie also gives people dishes that were talked about a lot. In the social media world, those would be posts that get a lot of engagement — for instance, clicks, likes and shares.

And what really shocks people or riles them up? False or misleading information ….

No wonder, then, that social media platforms have become a haven for mis- or disinformation. Posts can be fun or drama-inducing, but they don’t have to be the least bit true.
