A New Test of Image Theory

Area of Science:

• Decision Sciences
• Cognitive Psychology
• Marketing Science

Background:

• Multiattribute choice procedures involve screening alternatives.
• Two common screening hypotheses are the editing phase and the compatibility test.
• Eliciting parameters for the compatibility test can be challenging.

Purpose of the Study:

• To investigate the predictive accuracy of two screening hypotheses in multiattribute choice.
• To develop a novel method for evaluating the compatibility test without direct parameter elicitation.
• To compare the consistency rates of the editing phase versus the compatibility test.

Main Methods:

• Developed a new method to treat importance weights and rejection thresholds as latent parameters for the compatibility test.
• Designed experiments to test the hypotheses of the editing phase and the compatibility test.
• Applied Selten's measure of predictive success to validate findings.

Main Results:

• The compatibility test demonstrated significantly higher consistency rates (approximately 70%) compared to the editing hypothesis (approximately 15%).
• The developed method successfully assessed the compatibility test's application without requiring explicit subject parameters.
• Selten's measure of predictive success supported the superiority of the compatibility test.

Conclusions:

• The compatibility test is a more reliable screening mechanism in two-staged choice procedures than the editing phase.
• The novel method offers a practical approach to evaluating the compatibility test in decision-making research.
• Findings have implications for understanding and modeling consumer choice behavior.
