The Rational Experiental Inventory (REI)

Online version of the Rational Experiental Inventory

The Rational Experiental Inventory (REI) was published by Pacini & Epstein in 1999. The theoretical basis for this questionnaire is Epstein’s theoretical work, known as the Cognitive Experiential Self Theory (CEST).

According to this theory, each person to some extent uses two conceptually different thinking styles: a preconscious experiential system (fast intuitive automatic) and a conscious rational system (slower logical)

A Rational thinking style and an Experiential thinking style

The rational style of thinking involves analytics of events and consequences, logical reasoning and making emotion-free decisions based on the conclusions drawn. Accordingly, this style of thinking is slower.

The experiential thinking style involves faster action based on emotions, intuition, and other immediate reactions. People with a dominant experiential style are often impatient and make rash decisions.
