Polarization in social media threatens democracy

Social Media Polarization Threatens Democracy

In a recent publication by Sitra (No. 256, 2026), social media polarization is discussed as a phenomenon that already threatens democracy. Polarization arises from the combined effect of many factors, with platform algorithms playing a central role by favoring content that evokes strong emotions. This is a result of a business model in which user attention is the most valuable resource and is maximized at any cost.

This business model also explains why hate speech, conspiracy theories, and false information spread so effectively. Disinformation (intentional false information) and misinformation (unintentional false information) fuel distrust and polarization. Populist communication skillfully exploits this environment. In the Finnish context, for example, debt or tax populism can be used to win elections.

The situation is worsened by the fact that the rules of public discussion are shaped by the deregulated models of media platforms developed in the United States. This is also connected to political power: the relationship between tech giants and political actors is worryingly close. It is therefore hardly a coincidence that right-wing and hostile content structurally receives more visibility.

Social media communication styles themselves intensify the problem. Compressing ideas into short posts, digging up old writings, and the fast pace of short videos favor simplification and the loss of context. This makes constructive discussion difficult and increases the risk of misunderstandings. However, responsibility for the tone of discussion also lies with individuals and decision-makers. The tone of public debate will not change without an example from above. Political leaders and influencers should commit to constructive discussion and base their claims on facts.

Polarization also does not affect everyone equally. Female politicians and people belonging to minorities systematically face more hostile commentary. This is therefore a problem for society as a whole.

Solutions to the problem do exist, and for example the European Union has a key role as a developer of regulation; steps toward stricter platform responsibility have already been seen. However, the measures have not been sufficient, and national social media bans for minors will not solve the problem either.

Social media polarization is not an inevitable development, but stopping it requires both structural changes and cultural change. Without them, there is a risk of ending up among the group of shrinking democracies.
