Introduction to Quantum Cognition
Quantum cognition is a new field that uses quantum math to study how we think and make decisions. It’s a fresh way to look at human thought and decision-making. Researchers are now exploring how it can explain things that have been hard to understand for a long time.
Definition of Quantum Cognition
Quantum cognition uses
quantum probability
to study psychology when regular probability doesn’t work well
4
. It models our thought processes with quantum mechanics, which is different from regular logic
4
. By using quantum ideas like
superposition
and entanglement, it tries to give a clearer picture of how we think.
Brief History of Quantum Theory in Psychology
The idea of using quantum theory in psychology isn’t new. Niels Bohr first talked about
complementarity
, a key quantum idea, which came from psychology
4
. Over time, researchers like Henry Stapp and Giuseppe Vitiello have looked into how quantum theory can explain brain functions
5
.
Now, experts like Andrei Khrennikov and Jerome Busemeyer are pushing the field forward. They use quantum ideas to explain tricky
cognitive phenomena
4
. Their work shows how events can affect each other in complex ways and how context matters in decision-making. This field is growing fast, promising big changes in how we see the
human mind
6
.
Challenges for Classical Probability Theory
Classical probability theory
has been the main way to study human thinking and decision-making. But, researchers have found problems it can’t solve well. These issues include the conjunction and disjunction fallacies, and the
sure-thing principle
not working as expected. These problems have been seen in many studies
7
.
The early founders of quantum mechanics found issues with classical probability when they looked at their data. This led to the idea of
quantum probability
in the 1960s. This new approach looks at how we think differently, offering a new way to understand our minds
8
.
Conjunction Fallacy
The
conjunction fallacy
shows how our judgments don’t always follow classical probability rules. In an experiment, people were given a story about a person named Linda. They were asked to guess the chances of different things about Linda. Often, they thought “Linda is a bank teller and a feminist” was more likely than just “Linda is a bank teller.” This goes against the rule that the chance of both things happening can’t be more than the chance of each happening alone.
Disjunction Fallacy
The
disjunction fallacy
is similar. People often think the chance of either A or B happening is less than the chance of A or B happening alone. This mistake has been seen in things like medical diagnosis and legal cases. People tend to underestimate the chance of something happening when it could happen in many ways.
Failures of the Sure-Thing Principle
The
sure-thing principle
is a key rule in classical probability. It says if A is better than B in all situations, A should be chosen over B, even if we don’t know the situation. But, people don’t always make choices this way. Their preferences can change based on the situation or how the choices are presented.
These problems with classical probability have led researchers to look at other theories, like
quantum probability
. This new approach can handle the complex ways we think and make decisions better
7
. Quantum cognition offers a fresh view on the tricky issues classical theories can’t solve
7
.
Quantum-Like Models of Information Processing
Around two hundred experts are exploring how our brains process information like quantum mechanics. They’ve found about 5500 links on Google Scholar
9
. This new way looks at the uncertainty in how neurons work by using quantum ideas.
It treats the uncertainty in neurons as if it were in a quantum state. This helps us understand how our brains handle information in a new way
9
.
Now, scientists are using quantum ideas in many fields, like psychology and economics
10
. These models show how our brains process information in a way similar to quantum mechanics. They focus on how our mental states change when we make decisions
10
.
Quantum math helps us understand how our choices and actions are connected
10
. It uses complex math to predict our decisions, showing how our choices can affect each other in strange ways
10
.
Experts from different fields are using quantum math to solve complex problems
11
. They’ve found that our brains work in ways that are similar to quantum physics
11
. This means our choices and actions can be unpredictable, just like in quantum physics
11
.
The Born rule helps us understand how neurons might be quiet or active, based on probability
9
. This rule is used in quantum mechanics to predict outcomes.
Quantum ideas challenge old ways of thinking about probability and decision-making
10
. They show that some things can’t be known at the same time, which changes how we think about making choices
10
.
These ideas even help us understand how people can agree to disagree in a rational way
10
. This is different from traditional ways of thinking about decisions.
Researchers are applying these quantum ideas to real-world problems, like understanding how we make decisions
11
. They’re looking at how our brains handle complex information and make choices
11
.
But, there’s a big challenge in using quantum ideas in the brain. We need to understand how neurons really work together before we can fully grasp this concept
9
.
Quantum Cognition in Decision Making
Quantum cognition is a growing field that aims to change how we see decision-making. It uses quantum theory to understand human choices better
12
. Researchers look at things like
contextuality
and
quantum entanglement
to make more accurate models of how we think
12
.
Quantum cognition helps explain why we don’t always follow the
law of total probability
. Imagine you could play two rounds of a coin toss, winning 00 or losing 00 each time. If you don’t know the first round’s result, many people choose not to play the second round. This goes against the
law of total probability
3
.
This paradox can be solved with
quantum interference
, similar to the double-slit experiment. Quantum cognition says our choices are influenced by more than just logic. This leads to choices that seem irrational
3
.
Violations of the Law of Total Probability
The
law of total probability
is key in
classical probability theory
. It says we can figure out the chance of an event by adding up all possible outcomes. But, humans often don’t follow this law, especially when things are uncertain
12
.
Researchers use quantum statistics to study decision-making. They’ve published their work in important journals like Foundations of Science and Journal of Mathematical Psychology
12
. Their findings show quantum theory can help us understand the mind better, leading to new discoveries in psychology and decision-making
12
.
Interference Effects in Decision Making
Quantum interference
helps explain strange results in decision-making experiments. For example, the
Prisoner’s Dilemma
shows choices that don’t match
classical logic
3
.
By using quantum probability, researchers show how different thoughts can interfere with each other. This helps explain why we make certain choices. They’ve also applied this to paradoxes in economics, like the Allais and Ellsberg paradoxes
3
.
Paradox
Description
Quantum Explanation
Allais Paradox
Violation of expected utility theory
Interference
between competing preferences
Ellsberg Paradox
Aversion to ambiguity in decision-making
Superposition
of cognitive states
Machina Paradox
Inconsistency in choice under uncertainty
Contextual influence on decision-making
Quantum cognition offers a new view on these paradoxes. It gives a clear explanation for why our choices seem irrational. By looking at how our thoughts are connected, quantum models can change how we see the
human mind
12
3
.
Quantum Models of Human Probability Judgments
Recently,
quantum probability theory
has become a key tool for
understanding
how we make decisions and reason. Jennifer Trueblood, James Yearsley, and Emmanuel Pothos have used it to explain five important aspects of human thinking
13
. This theory brings a new idea to the table—the way questions work together and affect our thinking order.
Quantum probability offers a clear explanation for common mistakes in thinking, like mixing up “and” and “or”. It also helps us understand how the order of our thoughts affects our judgments
14
. This theory has many uses, from how we combine ideas to how we remember things and make decisions
14
.
Explaining Conjunction and Disjunction Errors
A
conjunction error
happens when we think two unlikely events are more likely together than one of them alone. However, a
disjunction error
is when we think one likely event is more likely than either it or another unlikely event. Quantum theory sheds light on these errors by looking at how our thoughts overlap with different possibilities
14
.
Busemeyer et al. (2011) suggested a way to calculate the probability of two events together, which was tested by Stolarz-Fantino et al. (2003) and Gavanski and Roskos-Ewoldsen (1991)
14
. This method involves moving from one thought to another, affecting how we judge the likelihood of events.
Compatibility and Order Effects on Probability Judgments
The quantum model talks about how questions work together and how this changes our thinking order. When two events can’t happen at the same time, the order we think of them in changes our final judgment. This is known as the order effect and has been seen in many studies.
Pothos et al. (2013) came up with a way to measure how similar events are and how we think of them in order
14
. This idea helps explain many mistakes we make in guessing probabilities and how the order matters.

In summary,
quantum probability theory
is a strong tool for understanding how we make
probability judgments
. It explains errors like mixing up “and” and “or”, and how the order of our thoughts affects our judgments. This theory also shows how our thinking can be simple or complex, depending on the situation
13
.
Quantum Approaches to Knowledge Representation
Quantum cognition has made big strides in understanding how our minds work with knowledge. By linking quantum mechanics to our brain’s workings, researchers have found new insights into how we form and combine ideas
15
. This new view helps us understand how ideas change when they come together and how they use
quantum entanglement
in meaning.
Contextuality of Concepts
Quantum cognition shows that ideas change based on the situation. Like how quantum particles act differently when measured, our ideas change with the context
16
. This helps us see how our thoughts can be flexible and adapt to complex situations.
Emergent Properties in Concept Combinations
When we mix ideas, new things come out that weren’t there before. This is key in quantum cognition research
15
. Using quantum entanglement to understand how ideas combine helps us grasp these new properties and the depth of our thoughts.
Quantum entanglement helps us see how combining ideas creates new meanings and connections.
Quantum Entanglement and Concept Semantics
Quantum entanglement is a big idea in physics that helps us understand how ideas combine
16
. By seeing ideas as entangled states, researchers can explain tricky brain phenomena like the
pet-fish problem
and the
guppy effect
. This view also helps with understanding how ideas work together.

Using

has opened new ways to understand our complex minds. By focusing on how ideas change with the situation, and using entanglement to model new properties, researchers are creating better models of how we think.
Quantum cognition is growing and promises to reveal more about how we think. It could lead to smarter artificial intelligence that’s more like our brains
16
15
.
Quantum Cognition
Quantum cognition is a field that uses quantum theory to study how we make decisions and reason. It gives us new ways to understand our thinking, especially when things don’t fit with classical ideas
17
. Researchers use quantum mechanics to make better models of how our minds work.
Superposition and the Emergence of New Concepts
Quantum cognition talks about the idea of
quantum superposition
. This means when we mix two concepts together, a new idea comes out that’s more than just the sum of its parts
18
. This is how our minds create new and creative ideas by combining different thoughts.
Researchers use
Fock space
math to study how concepts combine and why they don’t always follow classical rules
18
. They look at how our thoughts interact and how quantum effects help us understand why we sometimes think certain things are more typical than others.
Explaining the Pet-Fish Problem
The
Pet-Fish problem
shows how classical probability can’t fully explain human thinking. People often give weird answers when asked about typical pets or fish
17
. Quantum cognition, however, can explain this in a better way.
Using
quantum superposition
and
interference
, scientists have made models that predict new ideas and how we judge typicality
19
. These models consider how our thoughts interact and the role of quantum entanglement in our thinking.

This table shows how quantum cognition does better than classical probability in predicting how we judge things like “Pet AND Fish” and “Pet OR Fish”
19
. By using quantum ideas, these models give a clearer picture of how we form ideas and reason.
Quantum cognition offers a powerful framework for understanding the complexities of human thought and decision-making. It opens up new avenues for exploring the mind and developing more sophisticated models of cognition.
As research in quantum cognition grows, it could change how we see the
human mind
. It could lead to new ideas in artificial intelligence, decision support systems, and cognitive psychology
17
.
Applications in Semantic Analysis and Information Retrieval
Quantum theory’s math has been used to understand words and language bits as vectors in a
semantic space
. This shows how language works with context, entanglement, and emergence in our minds
20
. This method is useful for many behaviors, including how we talk
20
.
A ‘quantum meaning based’ framework has been created for finding information in texts
21
. This method shows how well quantum ideas work in understanding our minds
21
. A mix of classical and quantum methods has been tested for better language processing
21
.
The State Context Property (SCoP) helps model our thoughts and meanings in a quantum way
21
. Researchers tested if words in a document match what someone thinks when writing
21
. They also looked into how to make high-dimensional vectors for understanding language better
21
.
The quantum way of finding information is more accurate, making search results better
20
.
This quantum approach to understanding us and language is still growing. It could lead to new ways of finding meaning in information
20
. Early tests show it could be useful for analyzing language
20
.
This study shows how quantum thinking can help in many areas, like finding information, making smart machines, and robotics

Key Principles of Quantum Cognition
Quantum cognition blends quantum mechanics with
cognitive science
to explore how we think and make decisions
23
. This field has grown fast, offering a new way to understand our minds
24
. It focuses on two main ideas:
complementarity
and
superposition states
.
Complementarity in Psychological Measurements
Complementarity
is key in quantum theory, showing how our thoughts change when we look at things in different ways
24
. It says that some thoughts need us to see things from different angles, one after the other. This means the first thought can change how we think about the next one, making them hard to mix
24
.
“The principle of complementarity is a key concept in quantum cognition, explaining
order effects
in psychological studies and the incompatibility of certain cognitive measures.”
Superposition States in Cognitive Processes
Superposition
means we can be in many states at once, like having many answers to a question all at once
23
. We’re not stuck in one answer until we choose it. This idea helps explain how our thoughts can mix and affect each other, showing the confusion or doubt we feel.
Quantum cognition uses these ideas to understand how we make decisions and think
23
. It helps AI systems think more like us, making them better at predicting our choices and helping us in personal ways
23
. This approach gives us new ways to study how our minds work and explain strange things about thinking.
Quantum Principle
Cognitive Implications
Complementarity
Order effects
in psychological measures, incompatible cognitive perspectives
Superposition States
Indefinite cognitive states,
wave interference potentials
, intrinsic representation of conflict and uncertainty
Using quantum ideas in studying the mind could change how we see decision-making and thinking
23
. As quantum cognition grows, it might lead to new ways to help with mental health, improve thinking skills, and make AI better at understanding us
23
.
Classical vs. Quantum Models of Cognition
Quantum cognition is a new area that challenges old ideas about how we think and make decisions. Classical models used to be the main way to understand our minds. But they rely on assumptions that might not always be true. Quantum models offer a new view, showing how complex and uncertain our thoughts can be.
One big difference is how we look at things in classical and
quantum logic
. In
classical logic
, the order of things doesn’t change the outcome. But in quantum theory, some things can’t be looked at together without changing the result
25
. This idea, called complementarity, helps us understand how our memories work
25
.
Another key difference is the
distributive axiom
.
Classical logic
follows it, but quantum theory doesn’t always. In classical probability, we base our chances of something happening on clear facts. Quantum models let us think about a person being in two states at once, like being guilty or not
25
. This shows how human decisions can be complex and uncertain.
Quantum models also change how we look at
joint probability
. Classical theory says we can add up the chances of different outcomes. But quantum theory shows that some outcomes can affect each other in ways we can’t predict
25
. This has been seen in psychological tests, showing that quantum models might better explain some human behaviors.
Commutative and Distributive Axioms
The commutative and distributive axioms are key in classical logic and probability. They say that the order of looking at two things doesn’t change the result. But in quantum cognition, the order can matter, especially when thinking about negation and conjunction
25
.
The
distributive axiom
also has a quantum twist. It says A and (B or C) is the same as (A and B) or (A and C). But
quantum logic
doesn’t always follow this, leading to new ideas and ways to understand complex thought processes
25
.
Differences in Joint Probability Rules
Looking at
joint probability
shows big differences between classical and quantum models. In classical theory, we multiply the chances of two events to get their joint chance. But in quantum cognition, entanglement means some events are connected in ways classical theory can’t explain
25
. This leads to results that break the rules of classical probability, proving that some human thought is quantum in nature.

Commutative axiom

Commutative axiom

Distributive axiom

Law of total probability holds

Joint probabilities based on independence
Joint probabilities can exhibit entanglement
Recent studies have looked into how quantum models can predict human decisions. A study in
Nature Human Behavior
compared quantum and classical models in the Iowa Gambling Task
19
. Quantum models didn’t beat classical ones, but they showed they could be useful for
future research
19
.
The Iowa Gambling Task tests how people learn from mistakes and change their decisions. It was done with healthy people and those addicted to nicotine
19
. Brain scans during the task showed which brain areas were active, showing the complex processes behind decision-making and learning
19
.
Quantum cognition is growing and could change how we understand human thought and decision-making. By using quantum theory, researchers are creating a more detailed and accurate model of how we think.
Evidence for Quantum Cognition
Quantum theory is now being applied in
cognitive science
, a field known as quantum cognition. This area aims to explain complex mental processes. It looks at how brain activity relates to mental processes
26
. Authors like A. Y. Khrennikov and P. D. Bruza have contributed to this field since the 1980s
27
.
Quantum theory shows promise in understanding how our minds work. One key idea is that the order of questions affects our answers. This is known as
order effects
27
.
Measurement Order Effects in Psychology
Order effects are common in psychology studies. They make it hard to predict results. Quantum cognition offers a new way to understand these effects.
Quantum events happen in our brains and other living things
26
. The double-slit experiment shows how particles act differently based on their path. Similarly, our answers can change based on the order of questions.
The Quantum Question (QQ) Equality
The
quantum question equality
is a key prediction from quantum theory. It helps us see if quantum models work for understanding
question order effects
. This equality says the probability of certain answers should be the same in different question orders.
The QQ equality: P(A,B) = P(B,A) × cos²(θ/2)
Recent studies support the QQ equality in many psychological experiments. Wang et al. (2014) found strong evidence for it in 70 different surveys
26
. This shows quantum theory can help explain how question order affects our answers.
Dataset
Sample Size
QQ Equality Supported

General Social Survey

World Values Survey
2,000

The QQ equality is a test for quantum models in psychology. Its support in various studies shows quantum cognition’s strength. This framework helps explain complex psychological phenomena
27
.
quantum cognition offers new insights into how our minds work. With ongoing research, quantum models may become key to understanding human thought.
Advantages of the Quantum Framework
Quantum cognition brings a new way to understand how we make decisions and reason. It uses quantum math to explain things that classical theories can’t. This has led to new insights into how our minds work
28
.
Quantum thinking helps us understand complex ideas like contextuality and superposition in our minds. It shows that our thoughts and choices don’t always follow classical rules
28
. This has led to new models that better explain how we reason.
Providing Coherent Explanations for Puzzling Phenomena
Quantum cognition has a lot to say about cognitive biases and fallacies. It explains things like the
conjunction fallacy
and
question order effects
using quantum ideas
in cognitive modeling
.
Quantum cognition is not just about fitting existing data but also about making new a priori predictions and providing novel insights into the human mind.
This approach helps us understand human cognition and decision-making in a new way. It not only explains what we already know but also predicts new things. This opens up new areas for research.
Offering New Conceptual Tools for Cognitive Modeling
The quantum framework also gives us new tools for modeling the mind. Concepts like superposition and entanglement help create more accurate models of human thought.
Superposition lets us handle conflicting beliefs or consider many options at once
28
. This idea helps explain how we come up with new ideas and deal with cognitive dissonance.
Also, the quantum approach offers new math tools like Hilbert spaces and density matrices for complex cognitive processes. These tools could greatly improve our understanding of human thought and lead to more precise models.
quantum cognition is very promising for understanding human decision-making and reasoning. It offers clear explanations for complex phenomena and new tools for modeling the mind. This could lead to major breakthroughs in cognitive science.
Limitations and Criticisms of Quantum Cognition
Quantum cognition research has made strides in explaining some mysteries in psychology. Yet, there are still
limitations
and
criticisms
to consider. Many papers on “quantum cognition” are not truly about
quantum mechanics
. Instead, they show how the brain works in ways similar to quantum theory’s probability logic
17
. Most quantum cognition models are actually deterministic, not truly random
17
.
Another issue is the lack of solid evidence for quantum cognition in the brain. The brain is a classical system with billions of neurons. It’s hard to see how quantum effects could play a big role in it
17
. There’s no strong proof that quantum effects help with brain processes, which makes quantum consciousness theories hard to accept
17
. Some experts believe the brain works like an analog computer, not a quantum one
17
.
Some critics say quantum cognition models are just metaphors, not real theories. But supporters point out that these models have been proven to work well in practice
29
. They aim to link cognitive processes to classical mechanics using quantum ideas. They see the brain as working in a complex space, not a quantum one
17
.
To really prove quantum cognition’s worth, we need more solid evidence. Quantum-inspired models can help explain things like decision-making and cognitive biases
29
. But, quantum cognition needs more proof to show it’s better than traditional ways of thinking. The brain’s complexity and the lack of clear quantum effects in the brain are big hurdles
17
29
. Researchers are working hard to test and improve quantum models, hoping to see how far they can go.
Future Directions in Quantum Cognition Research
Quantum cognition is a growing field with many exciting areas to explore. It shows how our thoughts can be seen as elements in a complex space
30
. The way our thoughts change can be understood using quantum theory’s rules
30
. There’s still much to learn, especially about how “quantumness” affects our thinking
31
.
To move forward, we need better ways to test these ideas. Using complex math, we can study how our minds work
30
. Working together, experts from different fields can improve these methods. This teamwork brings together various skills and ideas.
Looking ahead, we can apply quantum thinking to real problems. Math from quantum physics helps us understand how we process information
31
. This could lead to better AI, information systems, and decision-making tools. The idea of artificial quantum intelligence suggests AI could work more like our brains
31
.
The tensor product structure of the Hilbert space, entanglements, superposition principle, projection postulate, and decoherence are intrinsic to any probabilistic system modeled on a Hilbert space
30
.
We need more studies to prove how quantum ideas work in different areas of thinking. This could include how we see things, remember things, make decisions, and reason. Such research will show if quantum thinking can explain more about our minds.
