How Brains Make Decisions

  title={How Brains Make Decisions},
  author={Vyacheslav I. Yukalov and Didier Sornette},
This chapter, dedicated to the memory of Mino Freund, summarizes the Quantum Decision Theory (QDT) that we have developed in a series of publications since 2008. We formulate a general mathematical scheme of how decisions are taken, using the point of view of psychological and cognitive sciences, without touching physiological aspects. The basic principles of how intelligence acts are discussed. The human brain processes involved in decisions are argued to be principally different from… 
Quantum-based Decision Making Under Uncertainty in the Presence of Entanglement for the Development of Optimal Strategies in Engineering Design
The work presented concerns the development of a quantum-based decision making model utilised in the identification of optimal strategies in engineering design under uncertainty in a quantum-like
Evolutionary Processes in Quantum Decision Theory
The review presents the basics of quantum decision theory, with an emphasis on temporary processes in decision making, and explains how an operationally-testable, rational choice between alternatives differs from a choice decorated by irrational feelings.
Beliefs, Actions, and Rationality in Strategical Decisions.
A belief-action entanglement model is developed that provides a good account of the empirical results of interference effects obtained from a new experiment in which 493 participants played a six-stage centipede game against a computer agent.
Conceptual variables, quantum theory, and statistical inference theory
The simple consequences of an epistemic interpretation for some so called quantum paradoxes are discussed, and connections to statistical inference theory are discussed in a preliminary way, both through an example and through a brief discussion of quantum measurement theory.
Quantum Theory of Measurements as Quantum Decision Theory
It is shown that the correct mathematical foundation for the theory of measurements under uncertainty, as well as for quantum decision theory dealing with uncertain events, requires the use of positive operator-valued measure that is a generalization of projection- valued measure.
Aspects of Quantum Theory
The basic formalism of quantum theory is reviewed and put into my setting. In particular, spin and angular momentum are considered, and also e-variables like position and momentum. For the

On several levels, there is now a debate whether the concept of God can be made compatible with modern science. In an attempt to elucidate this debate, I give an account of my own experiences from
The Epistemic View Upon Science
This chapter gives the background for the book. Its relation to other views on the foundation of quantum theory are clarified and discussed. The fundamental notion of an e-variable (epistemic


Mathematical Structure of Quantum Decision Theory
It is demonstrated that all known anomalies and paradoxes, documented in the context of classical decision theory, are reducible to just a few mathematical archetypes, all of which allow the finding of straightforward explanations in the frame of the developed quantum approach.
Processing Information in Quantum Decision Theory
Conditional maximization of entropy, equivalent to the minimization of an information functional, makes it possible to connect the quantum and classical decision theories, showing that the latter is the limit of the former under vanishing interference terms.
Decision theory with prospect interference and entanglement
It is demonstrated how the violation of the Savage’s sure-thing principle, known as the disjunction effect, can be explained quantitatively as a result of the interference of intentions, when making decisions under uncertainty.
The making of intelligence
Concepts of intelligence wield a powerful influence on research into the brain and on how individuals progress in society. Yet, remarkably, there is still no agreed scientific consensus about what
Physics of risk and uncertainty in quantum decision making
A general methodology based on self-similar approximation theory for deriving the evolution equations for the probabilities of future prospects provides a novel classification of possible discount factors, which include the previously known cases (exponential or hyperbolic discounting), but also predicts a novel class of discount factors that decay to a strictly positive constant for very large future time horizons.
Scheme of thinking quantum systems
A general approach describing quantum decision procedures is developed. The approach can be applied to quantum information processing, quantum computing, creation of artificial quantum intelligence,
What Intelligence Tests Miss: The Psychology of Rational Thought
Critics of intelligence tests-writers such as Robert Sternberg, Howard Gardner, and Daniel Goleman-have argued in recent years that these tests neglect important qualities such as emotion, empathy,
Higher Cortical Functions in Man
Among the authors' patients was a bookkeeper with a severe form of sensory aphasia who could still draw up the annual balance sheet in spite of severe disturbances of speech and although he was unable to remember the names of his subordinates and used to refer to them incorrectly.
Role of Information in Decision Making of Social Agents
The influence of additional information on the decision making of agents, who are the interacting members of a society, is analyzed within the mathematical framework based on the use of quantum
