The author argues that total “engagement” hides different acts: likes and reposts are cheap reactions, while replies require someone to add a comment—so similar totals can mean very different audience behavior.

Across Arabic and English posts (inflation, Fed policy, elections), uncertain wording drew far more replies (~82% more in the English replication) than likes or reposts, a pattern labeled the Uncertainty–Reply Asymmetry.

Loud reply threads therefore show conversation, not settled public opinion; journalists and institutions should not treat comment volume as proof of what most people believe.

Social media has made public reaction more visible than ever. A political statement, breaking-news update, or uncertain claim can attract thousands of interactions within minutes, creating the impression that we are watching public opinion form in real time.

But visibility is not the same as understanding.

Digital activity is increasingly used to interpret how audiences respond to events, institutions, claims, and public debates. Large numbers of interactions can quickly become evidence that an issue is resonating, provoking opposition, or generating support.

The difficulty is that the activity we observe online does not necessarily tell us what people believe.

My research into what I call the Uncertainty–Reply Asymmetry points to one reason why. Across separate analyses, uncertainty was associated disproportionately with replies rather than with likes or reposts.

That pattern raises a broader question: when people respond intensely to uncertain information, are we observing stronger opinions—or simply more conversation?

Why Social Media “Engagement” Can Be Misleading 

Social media platforms compress very different forms of activity into a deceptively simple idea: engagement.

Likes, reposts, replies, clicks, and other interactions are commonly grouped together when evaluating how strongly audiences responded to a piece of content. The resulting numbers are useful, but aggregation can hide an important distinction: these actions are not interchangeable.

Two posts may generate similar amounts of total engagement while producing entirely different patterns underneath. One may receive thousands of likes and very little discussion. Another may receive relatively few likes but hundreds of replies. Calling both highly engaging is technically reasonable, but analytically........
