Democracy can fail even when everyone votes and counts are fair.

What makes a decision process truly democratic? Instead of looking at complex systems, this paper finds the bare minimum rules needed. The researchers treat any collective choice as a tool that turns individual expressions into a shared outcome. To count as democratic, a process needs four conditions together: universal expression, count-dependence, autonomy of judgement, and absence of coercion. The core finding is that democracy can break down in two distinct ways. First, coercion stops people from expressing what they genuinely think. Second, a lack of autonomy means outside manipulation shapes their thoughts before they even speak. Because of this, a system can include everyone and count every vote fairly, yet still fail to be democratic if the votes come from forced speech or manipulated minds. This framework works for any setup, from standard referenda to digital voting and algorithms.

Why it matters

This matters for anyone designing voting systems, from governments to tech platforms. It shows that even fair counting isn't enough—what people express must be freely given and their judgments must not be manipulated. Without both, a procedure looks democratic but isn't.
