Quiz: The Four Tendencies

Take the free quiz to discover whether you’re an Upholder, Questioner, Obliger, or Rebel.

Self-knowledge is a key to happiness. The Four Tendencies personality framework offers insight into how we respond to expectations—from ourselves and others—so that we can more effectively achieve our aims.

We all face two kinds of expectations—outer expectations (meet work deadlines, answer a request from a friend) and inner expectations (keep a New Year’s resolution, start meditating). Our response to expectations determines our “Tendency”—that is, whether we fit into the category of Upholder, Questioner, Obliger, or Rebel.

Knowing our Tendency can help us approach situations in ways that make us more likely to achieve our aims. We can make better decisions, meet deadlines, meet our promises to ourselves, suffer less stress, and engage more deeply with others. Just as important, understanding other people’s Tendencies can help us reduce conflict and make significant, lasting change.

Developed by happiness and habit expert Gretchen Rubin, using years of research and observation, the Four Tendencies personality framework answers the question “How do I get myself—and others—to do what I want?” Her book, The Four Tendencies is a New York Times bestseller, and over 3.5 million people have taken her quiz.

The quiz is free, and takes about 10 minutes to complete, and answers are confidential.
