May we verify non existing dispersion free ensembles by application of quantum mechanics in experiments at perceptive and cognitive level?

See on Scoop.itBounded Rationality and Beyond

Von Neumann in 1932 was the first to outline the possible non existence of dispersion free ensembles in quantum mechanics, and he used also such basic evidence to give a preliminary proof on incompatibility between quantum mechanics and (non-contextual) hidden variables theory. In the present paper we give a detailed theoretical elaboration on the manner in which such fundamental subject could be explored at perceptive and cognitive level in humans. We also discuss a general design of the experiment that we have in progress so to give direct indications to other researchers engaged in such field.

Death is Optional – A Conversation: Yuval Noah Harari, Daniel Kahneman [3.4.15] ,EDGE

See on Scoop.itcognition

Once you really solve a problem like direct brain-computer interface … when brains and computers can interact directly, that’s it, that’s the end of history, that’s the end of biology as we know it. Nobody has a clue what will happen once you solve this. If life can break out of the organic realm into the vastness of the inorganic realm, you cannot even begin to imagine what the consequences will be, because your imagination at present is organic. So if there is a point of Singularity, by definition, we have no way of even starting to imagine what’s happening beyond that.

FastTFriend’s insight:

From Article: “I think that many of these science fiction scenarios, that computers will be like humans, are wrong. Computers are very, very, very far from being like humans, especially when it comes to consciousness. The problem is different, that the system, the military and economic and political system doesn’t really need consciousness.”

Design of an Experiment to Test Quantum Probabilistic Behavior of the Financial market

See on Scoop.itBounded Rationality and Beyond

The recent crash demonstrated (once again) that the description of the financial market by present financial mathematics cannot be considered as totally satisfactory. We remind that nowadays financial mathematics is heavily based on the use of random variables and stochastic processes which are described by Kolmogorov’s measure-theoretic model for probability (“classical probabilistic model”). I speculate that the present financial crises is a sign (a kind of experiment to test validity of classical probability theory at the financial market) that the use of this model in finances should be either totally rejected or at least completed. One of the best candidates for a new probabilistic financial model is quantum probability or its generalizations, so to say quantum-like (QL) models. Speculations that the financial market may be nonclassical have been present in scientific literature for many years. The aim of this note is to move from the domain of speculation to rigorous statistical arguments in favor of probabilistic nonclassicality of the financial market. I design a corresponding statistical test which is based on violation of the formula of total probability (FTP). The latter is the basic in classical probability and its violation would be a strong sign in favor of QL behavior at the market.

On the Existence of Quantum Wave Function and Quantum Interference Effects in Mental States: An Experimental Confirmation during Perception and Cognition in Humans

See on Scoop.itBounded Rationality and Beyond

We introduce the quantum theoretical formulation to determine a posteriori, if existing, the quantum wave functions and to estimate the quantum interference effects of mental states. Such quantum features are actually found in the case of an experiment involving the perception and the cognition in humans. Also some specific psychological variables are introduced and it is obtained that they characterize in a stringent manner the quantum behaviour of mind during such performed experiment.

Quantum dynamics of human decision-making

See on Scoop.itBounded Rationality and Beyond

Abstract: A quantum dynamic model of decision-making is presented, and it is compared with a previously established Markov model. Both the quantum and the Markov models are formulated as random walk decision processes, but the probabilistic principles differ between the two approaches. Quantum dynamics describe the evolution of complex valued probability amplitudes over time, whereas Markov models describe the evolution of real valued probabilities over time. Quantum dynamics generate interference effects, which are not possible with Markov models. An interference effect occurs when the probability of the union of two possible paths is smaller than each individual path alone. The choice probabilities and distribution of choice response time for the quantum model are derived, and the predictions are contrasted with the Markov model.
