What Populism Is — Beyond the Buzzword

Populism is the most overused word in contemporary politics — applied to everyone from left-wing firebrands to right-wing nationalists, often as little more than an insult. But political scientists use it to describe something specific, and recovering that precision matters, because the concept explains real patterns across otherwise unrelated movements.

The core definition

The influential scholarly definition, associated with researchers like Cas Mudde, treats populism as a thin ideology: society is divided into two homogeneous camps — the pure people versus the corrupt elite — and politics should express the general will of the people. Note what this definition does not include: any position on economics, immigration, or the size of government. Populism is a framework, not a program, which is why it attaches to both left and right.

Left populism typically counterposes the people against economic elites — banks, corporations, austerity governments. Right populism counterposes the people against political and cultural elites, often adding an exclusionary definition of who counts as the people. The shared move is moral: opponents are not wrong but illegitimate, enemies of the people rather than fellow citizens.

Why the label misleads

Three confusions recur. First, populism is not the same as popularity — winning votes does not make a politician populist. Second, it is not the same as anti-establishment rhetoric, which mainstream politicians also use. Third, and most importantly, calling something populist explains its style while saying nothing about whether its claims are true or its policies wise. The word has become a way to dismiss without engaging.

When it matters

Populism in power differs sharply from populism in opposition. Opposition populists can promise everything — the constraints are someone else's problem. Governing populists must deliver, and the record is instructive: some moderate into conventional administration, their radicalism dulled by institutional reality; others escalate, attacking the institutions that check them when results disappoint. The pattern reveals which populists were always authoritarians and which were merely angry. Economic stewardship is the usual test: movements built on economic grievance that fail to improve material conditions tend to double down on cultural warfare, substituting enemies for achievements. Voters eventually notice. The populist lifecycle — insurgency, victory, disillusionment — has repeated often enough to be predictable, which is precisely why established parties keep failing to interrupt it.

Populism becomes dangerous not when it criticizes elites — elites often deserve it — but when it rejects the institutional constraints that protect minorities and dissent: courts, press freedom, electoral rules. Scholars distinguish between populists who compete within the system and those who dismantle it once elected. The buzzword obscures this crucial line. The concept, properly used, draws it.
