Varied Individual Behavior: Some Theories, Measurement Methods and Models

Area of Science:

• Behavioral Economics
• Decision Theory
• Psychology

Background:

• Individual behavior often exhibits significant variation.
• Existing choice models may not fully capture the nuances of diverse behaviors.
• The utility derived from variety itself is a key, yet often overlooked, factor.

Purpose of the Study:

• To investigate the multifaceted causes of varied individual behavior.
• To define and incorporate the concept of variety in choice objects.
• To develop a theoretical framework and dynamic model for understanding varied behavior and choice predictability.

Main Methods:

• Formulation of a novel theory of varied behavior.
• Development of a dynamic choice model.
• Conceptual analysis of variety in choice objects.

Main Results:

• The proposed theory and model offer explanations for historical disagreements on choice predictability.
• The study highlights the direct utility of variety as a behavioral driver.
• The findings suggest limitations of current choice models for high-involvement decisions.

Conclusions:

• A new perspective on individual behavior and choice is presented.
• The model provides a more comprehensive understanding of choice predictability.
• Recommendations are made regarding the application of choice models to complex consumer decisions.
