Reason and Intuition01:37

Reason and Intuition

7.7K
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...

Decision Making: P-value Method01:09

Decision Making: P-value Method

7.1K
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim  is also stated. These statements can act as null and alternative hypotheses:  a null hypothesis would be a neutral statement while the alternative hypothesis can...

Decision Making: Traditional Method

The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Decision Making

1.2K
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.9K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Hindsight Biases01:12

Hindsight Biases

4.5K
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?

Area of Science:

  • Cognitive Science
  • Decision Theory
  • Quantum Physics

Background:

  • Classical probability theory struggles with paradoxical decision-making findings.
  • Quantum theory (QT) offers alternative models for decision processes.
  • QT's collapse postulate suggests measurements reset states, a key feature to investigate in cognition.

Purpose of the Study:

  • To find evidence for the collapse postulate in human cognition.
  • To investigate if quantum principles apply to decision-making.
  • To demonstrate a quantum Zeno effect in human decision processes.

Main Methods:

  • Studied decision-making in humans.
  • Investigated the impact of continuous judgments on opinion change.
  • Looked for evidence of the quantum Zeno effect in cognitive processes.

Main Results:

  • Demonstrated a quantum Zeno effect in human decision-making.
  • Observed that continuous judgments slow down opinion change.
  • Provided empirical evidence supporting quantum principles in decision theory.

Conclusions:

  • Quantum principles, specifically the collapse postulate, appear relevant to human decision-making.
  • The quantum Zeno effect is observable in cognitive processes.
  • Quantum decision theory provides a valuable framework for understanding certain decision behaviors.
