Exhibit A of social media as outrage merchants:

I share a lot of academic research on Chinese social media and frequently find that in the comment section, offensive one-liners get ranked higher than sincere discussions even though the former has fewer likes (see screenshot).

Weibo’s comment section has a Reddit-like nested structure, and the ranking algorithm takes into account **all** likes garnered by the parent comment and its children.

You can imagine how this kind of algorithm amplifies resentment and distorts our perception of public opinion.

I share a lot of gender-related research online.

Usually the top-ranked comment would be something offensive and unhelpful: “All women are...!”

This comment would then attract lots of counter-punches, making it even more attractive from the ranking algorithm’s perspective.

In the screenshot, the lower-ranked comment (123 likes) comes from an econ prof who thoughtfully engaged with my post.

The higher-ranked comment (53 likes) is much shorter and dismisses my post without giving a reason. It’s ranked higher bc many people came to criticize him.

It seems like almost all platforms amplify extreme, outrage-inducing content because it attracts counter-punches, which then boost the platforms’ engagement numbers.

Does this kind of ranking algorithm make us perceive less consensus and more polarization than there actually is?
