Never Gonna Give You Up Even When It Is Suboptimal

Area of Science:

• Behavioral Ecology
• Cognitive Science
• Human Decision-Making

Background:

• Animals adapt foraging strategies to environments, but human adaptability remains unclear.
• Previous studies show limited evidence of humans changing foraging strategies.

Purpose of the Study:

• Investigate human adaptation of foraging strategies in varying environments.
• Understand why individuals may persist with a single strategy.
• Examine the role of strategy performance differences in adaptation.

Main Methods:

• Conducted two human foraging experiments to identify participant strategies.
• Analyzed the performance of Give-Up Time (GUT), Fixed-Time, and Fixed-Number strategies.
• Utilized computer simulations to compare strategy performance under different conditions.

Main Results:

• Most participants consistently used the GUT strategy across all environments.
• The GUT strategy was employed even in conditions where Fixed-Time or Fixed-Number strategies were superior.
• Simulations revealed GUT performs well consistently and excels with variable resource quality.

Conclusions:

• Human foraging strategy choice may be influenced by consistent, satisfactory performance rather than optimal choice.
• The robust performance of the GUT strategy, particularly in variable environments, likely explains the observed lack of strategy switching.
