Mental models are a widely accepted source why decision-makers fail to make effective decisions. The concept of mental models was first introduced in the mental model theory (Johnson-Laird, 1983), defining mental models as a medium for mental representation by manipulating mental objects (making decisions) to solve a problem at hand. (Senge, 1990) makes use of the mental model concept in his research on “the learning organization”, where he defines mental models as “deeply ingrained assumptions, generalizations, or even pictures or image that influence how we understand the world and how we take action. Very often we are not consciously aware of our mental models or the effect they have on our behavior” (Senge, 1990), p.8.
