Decision Making: P-value Method01:09

Decision Making: P-value Method

5.9K
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

341
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...

Reason and Intuition

7.1K
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 Anchoring-and-Adjustment Heuristic

7.5K
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...

Impression Management Techniques III: Aligning Actions

30
Aligning actions are communicative strategies individuals employ to maintain social harmony and preserve personal identity in the face of potential disruptions to social norms. These actions are particularly important in managing social impressions when one's behavior might be seen as inappropriate, incompetent, or morally questionable.Types of Aligning ActionsThe three principal types of aligning actions are disclaimers, accounts, and apologies.DisclaimersDisclaimers are preventive; they are...

Summary

Complex real-life decisions require moving beyond simple binary choices. Understanding the interplay between deliberation space and evidence collection is key for effective meta-decision-making and optimal outcomes.

Area of Science:

  • Behavioral science
  • Cognitive science
  • Neural science

Background:

  • Traditional decision-making models often use binary choices, which oversimplify complex real-life scenarios.
  • Real-world decisions involve multiple options, graded judgments, and deferred choices, necessitating more nuanced approaches.

Purpose of the Study:

  • To explore how conventional decision-making models can accommodate real-life complexity.
  • To examine the interactive dynamics between criteria setting and evidence collection in decision-making.

Main Methods:

  • Focus on the interactive dynamics of criteria settings and evidence collection.
  • Analyze multi-stage, parallel decision-making through deliberation space.
  • Investigate meta-decision-making as a value-based exercise.

Main Results:

  • Decision-makers can utilize deliberation space for multi-stage, parallel processing with non-binary evidence.
  • The speed-accuracy tradeoff is central, with deliberation space enabling extended data collection.
  • Meta-decision-making involves balancing prior beliefs, information costs, and potential outcomes.

Conclusions:

  • Understanding deliberation space is crucial for optimizing decision-making processes.
  • Agency in decision-making is influenced by how parameters are set, either internally or by external factors.
  • Practical implications lie in recognizing and managing environmental influences on decision framing and urgency.
