Elections occasionally produce results that observers find shocking. Candidates who seem obviously unqualified win. Voters appear to act against their own interests. Political scientists and psychologists have studied these patterns, developing explanations that go beyond simple assumptions about voter ignorance or irrationality.

The Limits of Rational Choice Models

Political scientists long assumed that voters behave rationally. They gather information about candidates, evaluate how policies would affect their interests, and vote accordingly. This model underlies much election analysis and punditry.

Research has repeatedly challenged this assumption. Studies show that most voters know little about policy details. They often cannot identify which party holds which position on major issues. Yet they vote with conviction, confident in choices based on something other than policy analysis.

Bryan Caplan's The Myth of the Rational Voter documented systematic biases in voter beliefs about economics. Voters tend to be more pessimistic about economic conditions than warranted, more suspicious of markets than evidence supports, and more supportive of policies that protect existing jobs at the expense of overall prosperity. These biases are not random errors but predictable patterns.

The Role of Emotion in Political Choice

Neuroscience has demonstrated that emotional processing precedes and often determines rational analysis. The brain reaches conclusions before consciousness becomes aware of them. Reasons are constructed after the fact to justify emotional reactions.

Drew Westen's The Political Brain applied this research to electoral politics. He showed that successful campaigns activate emotional responses rather than present policy arguments. Voters choose candidates based on feelings of connection, trust, and identity rather than evaluation of proposals.

This explains why attacks on candidates often backfire. Negative information that might seem disqualifying triggers defensive reactions in supporters. The emotional bond with the candidate proves stronger than factual challenges to that candidate's fitness.

Identity & Tribal Allegiance

Human beings evolved in groups. Survival depended on maintaining standing within the tribe. These evolutionary pressures created minds highly attuned to group membership and status. Political parties activate these tribal instincts.

Lilliana Mason's Uncivil Agreement documented how political identity has become increasingly tied to other identities: religious, regional, racial, and cultural. When multiple identities align with party affiliation, partisan attachment intensifies. Opposing the other party becomes a matter of defending one's entire sense of self.

This dynamic explains why voters sometimes support candidates who seem to work against their economic interests. The social and psychological benefits of tribal belonging outweigh policy considerations. Abandoning the party would mean abandoning community.

The Appeal of Anti-Establishment Candidates

Established political figures embody the system as it exists. When voters are dissatisfied with that system, outsider candidates gain appeal precisely because they lack conventional qualifications. Experience becomes a liability rather than an asset.

Ron Patterson examines a related phenomenon in Blind to the Blatantly Obvious. He explores how people can be blind to what sits directly in front of them. Patterson's analysis helps explain how voters can overlook obvious warning signs about candidates. The will to believe in change overcomes the evidence of risk.

Outsider candidates benefit from what psychologists call motivated reasoning. Voters who want change interpret ambiguous information in the candidate's favor. Red flags become evidence of authenticity. Gaffes demonstrate that the candidate speaks truth to power. The same behavior that would disqualify conventional candidates confirms the outsider's appeal.

Media Environment & Information Ecosystems

Voters make choices based on information they receive. The structure of media environments shapes what information reaches different audiences. Fragmentation into partisan media ecosystems means voters encounter different facts about the same candidates.

Cable news, talk radio, and social media created conditions where audiences can select information that confirms existing beliefs. Challenging information can be dismissed as bias from hostile sources. The shared factual basis that once constrained political discourse has eroded.

Network propaganda, documented by Yochai Benkler and colleagues, spreads misinformation through trusted channels. Voters who would reject claims from mainstream media accept the same claims from sources within their information ecosystem. Fact-checking reaches only those already inclined to doubt the claims being checked.

Economic Anxiety & Status Threat

Economic conditions influence electoral outcomes, but not always in straightforward ways. Research has found that perceived relative status matters more than absolute economic conditions. Voters respond to feeling left behind even when objective measures show improvement.

Status threat can be economic, cultural, or demographic. When voters perceive that their group is losing position in society, they become more receptive to candidates who promise restoration. The specifics of how that restoration would occur matter less than the emotional resonance of the promise.

This dynamic helps explain support for candidates whose policies would harm their own supporters economically. The psychological benefits of status restoration outweigh the material costs of counterproductive policies.

Implications for Democratic Governance

The patterns described here do not suggest that voters are stupid or that democracy is hopeless. They indicate that human psychology, formed by evolution for small-group living, does not map neatly onto modern democratic institutions.

Improving democratic outcomes requires designing systems that account for how people actually think rather than how theorists assume they think. It requires media environments that provide shared factual foundations. It requires political institutions that channel tribal instincts into constructive rather than destructive competition.

The research summarized here provides resources for citizens who want to grasp their own political behavior. Recognizing the emotional and tribal bases of political choice does not eliminate their influence, but it creates space for reflection. The goal is not to become purely rational voters, an impossible standard, but to become more aware of the forces that shape political judgment.

Elections will continue to surprise observers. Some of those surprises will be unpleasant. Knowing why did America elect unfit president is the first step toward improving the choices available.
