What is quantum psychology?

A relationship between quantum mechanics and psychology was first postulated by the physicist Niels Bohr in the 1930s [1], but it is only in the last few years that serious research has taken place in this field. Although quantum psychology adopts a radically different theoretical approach to classical psychology it has nothing in common with the so-called metaphysical, transpersonal and “new age” theories that have misappropriated the name. In short:

  1. Quantum psychology asserts:
    • that information processing by the brain is best explained using concepts derived from quantum mechanics.
    • that information processing by the brain is best described using the mathematical language of quantum theory.

  2. Quantum psychology rejects:
    • the use of causal determinism, instead preferring to view cognitive processes as quantum probabilistic events which cannot be defined independently of either their measurement or their context.

  3. Quantum psychology does not claim that the brain is a “quantum computer”.

Who maintains this site?

This site is maintained by Rachael Bond a research student at the University of Sussex. Working under the supervision of Professor Tom Ormerod, her research is centred on the creation and development of a theory of decision making based on the principles of quantum mechanics. It is hoped that this model will provide greater insight into psychonomic behaviour than that offered by current theories.
