The Koala and the Kangaroo effects: from Melbourne to Algarve

This communication is the result of several discussions between five researchers about consumers and consumer behavior. In fact, we only stated an analogy between consumers and two animals (koalas and kangaroos). We propose an original way to classify participants in a survey (or experiment) as one of these two animals. With this, we hope to rise up some minds about the need to become more realistic and less theoretical when we try to explain our decisions and behaviors.
