Rational Experiental Inventory (REI)

Online version of the Rational Experiential Inventory

The Rational Experiential Inventory (REI) was published by Pacini and Epstein in 1999. The questionnaire builds on Epstein’s Cognitive-Experiential Self-Theory (CEST).

According to this theory, everyone uses two distinct thinking modes to some degree: a preconscious experiential system (fast, intuitive, automatic) and a conscious rational system (slower and more logical).

Rational and experiential thinking styles

The rational thinking style emphasizes analysis of events and consequences, logical reasoning, and relatively emotion-neutral decisions based on those conclusions. This mode tends to be slower and more deliberate.

The experiential thinking style favors quicker responses grounded in emotion, intuition, and immediate impressions. People who lean experiential are often more impatient and may decide impulsively under pressure.

1. I’m not that good at figuring out complicated problems
2. I try to avoid situations that require thinking in depth about something
3. I don’t have a very good sense of intuition
4. I like to rely on my intuitive impressions
5. I am not very good at solving problems that require careful logical analysis
6. I enjoy intellectual challenges
7. Using my gut feelings usually works well for me in figuring out problems in my life
8. Intuition can be a very useful way to solve problems
9. I am not a very analytical thinker
10. I don’t like to have to do a lot of thinking

Does a high intuition score mean I lack logical thinking?

No. In Epstein’s theory, the rational and experiential systems are relatively independent. You can be strong in analysis and in intuitive processing. The most adaptive approach is usually a flexible balance between the two, depending on the situation.

Can I trust my intuition for important decisions?

Intuition reflects the brain’s ability to draw rapidly on implicit learning from past experience. It often works well in familiar settings or under severe time pressure. For novel, high-stakes problems, deliberately applying a more rational style is usually wise.

How can the test results help my career?

Knowing your tendencies can help you choose strategies that fit the task. Rational thinkers often do well with structured analysis and long-range planning; experiential thinkers may be quicker to generate creative options and read social cues. Many roles benefit from both.

Can my thinking style change over time?

Basic preferences are fairly stable over time, but they are not fixed traits. You can strengthen rational habits through deliberate practice and skills training, and you can refine intuitive judgment through reflection, mindfulness, and varied real-world experience.
