Do you have a partisan bias? Take this quiz to find out.

Sure, you may claim that your political beliefs don't affect your non-political judgments, but is that really true? This Vox quiz is a foolproof way to find out.

It's an implicit-association test, which means it detects your subconscious, snap judgments rather than your conscious thoughts. The same test was used in a Stanford study on the polarization of the American electorate (PDF), which discussed how people discriminate against others based on party lines, noting that "party cues exert powerful effects on non-political judgments and behaviors."

The quiz accompanies a Vox feature story published Monday on how political affiliations are "becoming a fundamental identity in American life," fueling mutual animosity and discrimination between Republicans and Democrats. Take the quiz here.
