Big Five and Political Attitudes: Evidence and Limits
Editorial update:
Can personality explain political attitudes?
Big Five traits are associated with political attitudes in some studies, but the relationships depend on the attitude measured, the population and the political setting. Openness and Conscientiousness receive particular attention in this research. These are patterns across samples, not a method for identifying an individual's party, vote or beliefs. A personality profile cannot settle a political disagreement.
- Political ideology, policy views and party identity are different outcomes.
- A population association does not determine an individual's beliefs.
- Survey context can affect self-reported personality.
- Correlation alone does not show which factor causes the other.
What the research actually compares
In a US study, Gerber and colleagues (2010) examined Big Five traits alongside economic and social attitudes. The relationships differed across issue domains and social contexts. That finding challenges a simple interpretation in which one trait maps neatly onto one political position.
A later study by Bakker, Lelkes and Malka (2021) investigated the direction of influence using longitudinal data and survey experiments. Their findings suggest that political preferences and personality self-reports can influence each other. Making politics salient also affected how participants described themselves. The authors discuss limits to causal conclusions from panel models.
Some research links higher Openness with more liberal attitudes and higher Conscientiousness with more conservative attitudes. These summaries require the original study's definitions and setting. “Liberal” can refer to social values, economic policy or a party label, and those meanings are not identical across countries or periods.
Read the outcome before interpreting the trait
| Measure | What a study may ask | What it does not establish |
|---|---|---|
| Ideological identity | Where someone places themselves on a left–right scale. | Their answer to every policy question. |
| Policy attitude | Support for a specific proposal. | The party they will choose. |
| Party identification | Which party someone feels close to. | A fixed personality category. |
| Voting behavior | A reported choice in a particular election. | An enduring view on every issue. |
Use findings to ask better questions
Imagine two people who both prefer orderly routines. One supports a proposal because they expect it to make public services more predictable; the other opposes it because they expect disruption. This invented example illustrates a limitation of trait labels: knowing a preference for order does not tell you what consequences a person expects.
When reading a headline, ask which sample was studied, which political question was asked, how large the association was and whether personality and attitudes were measured at the same time. Then check whether the article distinguishes statistical prediction across a sample from an accurate prediction about one person.
Do not use a personality score to infer a colleague's politics or decide how to persuade them. If their views are relevant to a conversation, let them explain those views directly. Personality language is most useful here for understanding the research question and its limits.
Start with the Big Five model, then explore Openness, Conscientiousness and interpreting a profile. A personality profile for self-reflection is not a political classification.

Frequently asked questions
Can a Big Five score tell me which party someone supports?
No. Research associations describe tendencies across samples and depend on context. They do not identify a particular person’s party affiliation or vote.
Does Openness cause liberal political views?
An association does not establish that causal claim. Longitudinal and experimental research also examines whether politics and survey context influence how people describe their personality.
Why do political personality studies report different results?
Studies can differ in countries, time periods, samples, questionnaires and political outcomes. Economic attitudes, social attitudes, party identity and left–right self-placement should not be treated as the same measure.
