First Impression

First Impression

First impressions play a crucial role in social perception, shaping how individuals assess others in professional, academic, and interpersonal contexts. Psychological research highlights the significance of cognitive biases, such as the primacy and recency effects, which influence how people interpret and recall information.The Primacy Effect and Cognitive AnchoringThe primacy effect describes the tendency for initial information to impact judgment disproportionately. When individuals encounter...

Hindsight Biases

Hindsight Biases

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Cognitivism

Cognitivism

Cognitive psychology emerged as a significant field in the mid-20th century. It focused on understanding humans' internal mental processes. This approach emphasizes how people perceive, remember, think, and solve problems—elements critical to human cognition.
Previously dominated by behaviorism, which prioritized observable behaviors and largely ignored mental processes, psychology transformed in the 1950s. Cognitive psychologists argue that understanding how we think and process...

Unrealistic Optimism Bias

Unrealistic Optimism Bias

Unrealistic optimism bias is the tendency to overestimate the likelihood of positive outcomes. This cognitive bias makes individuals believe they are less likely to experience failures, setbacks, or risks and more likely to succeed than others. For example, people may assume they are less prone to health issues, accidents, or financial struggles than their peers, even when they share similar risk factors.One key component of this bias is the above-average effect, where individuals perceive...

Reason and Intuition

Reason and Intuition

The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

The Influence of Cognition on Affect

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...

Area of Science:

Cognitive Science
Quantum Mechanics
Economics

Background:

Classical decision-making models, including expected utility theory, struggle to explain certain human biases.
Projection bias, where individuals overestimate the extent to which their current preferences will persist in the future, violates classical probability laws.

Purpose of the Study:

To apply quantum mechanical probability concepts to cognitive science for improved modeling of human decision-making.
To explain projection bias and its inconsistencies with classical probability and expected utility theory using quantum probability interference.

Main Methods:

Leveraging dynamic geometric principles from quantum theory.
Applying Khrennikov's contextual probability model.
Utilizing the concept of probability interference.

Main Results:

Quantum probability interference successfully explains projection bias.
The model accounts for violations of the classical law of total probability and expected utility theory.
Khrennikov's contextual probability model was effectively applied to existing studies on hunger and projection bias.

Conclusions:

Probability interference offers an effective and accurate method for modeling projection bias.
Quantum cognition, through probability interference, provides a valuable framework for understanding economic decision-making.
This research expands the application of quantum cognition principles into the field of economics.
