Konstantinos V. Petrides

Konstantinos Vassilis Petrides (born November 25, 1972) is a Professor of Psychology and Psychometrics at University College London and the founding director of the London Psychometric Laboratory. He is the Secretary-Treasurer of the International Society for the Study of Individual Differences and Senior Associate Editor for the journal Personality and Individual Differences. His work has been published in various scientific journals, encyclopedias, and has been covered in major media outlets.

Petrides's various theories (including trait emotional intelligence and belief-importance theory) are all fully expanded and integrated within the grand system of Psychobionomy. The term Psychobionomy is derived from the Greek words ‘Psyche,’ which means soul or spirit, ‘Bio,’ which means life, and the suffix ‘-nomy,’ which means law. Psychobionomy can be classified as an ontological system within Philosophy of Mind aiming to discover and apply the essential laws of mind for the betterment of human psychology and life as a whole.

Central across Petrides’ theories is the notion that perceptions, in general, and self-perceptions, more specifically, have a creative influence on a person's life. The reality that people experience at any point in time is a function of how they perceive themselves and life, more broadly. By changing their perceptions, they can purposely effect desirable change in all areas of their lives. A full biographical entry can be found in Springer's Encyclopedia of Individual Differences.
