The Anchoring-and-Adjustment Heuristic

7.2K
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...

Testing a Claim about Standard Deviation

2.4K
A complete procedure to test a claim about population standard deviation or population variance is explained here.
The hypothesis testing for the claim of population standard deviation (or variance) requires the data and samples to be random and unbiased. The population distribution also must be normal. There is no specific requirement on the sample size as the estimation is based on the chi-square distribution.
As a first step, the hypothesis (null and alternative) concerning the claim about...

Summary
This summary is machine-generated.

Participants reduced information gathering when facing competition, improving decision-making speed. This effect persisted even without a rival, showing competition isn't essential for enhanced metareasoning and performance.

Area of Science:

  • Cognitive Psychology
  • Decision Science
  • Metacognition

Background:

  • Oversampling is common in sample-based decisions, even when speed is critical.
  • Competition can reduce information search, offering potential for improved decision strategies.

Purpose of the Study:

  • To investigate if competition enhances metareasoning and decision performance.
  • To determine if competition is necessary for participants to leverage metareasoning opportunities.

Main Methods:

  • 101 participants competed against a simulated rival in a decision-making task.
  • Sample size reduction was compared between competitive and control conditions.
  • The impact of observing a teammate's strategy on sample size was also examined.

Main Results:

  • Participants substantially reduced their sample size when competing against a rival.
  • This speed increase transferred to a non-competitive block, though strategy shifted.
  • Exposure to a teammate using small samples also reduced participant sample size.

Conclusions:

  • Competition can trigger metareasoning, leading to reduced information search and faster decisions.
  • Competition is not the sole factor; social learning also facilitates improved decision strategies.
  • Further research is needed to understand the metacognitive mechanisms driving performance improvements.
