Bounded personality diversity in collective problem-solving enhances performance. This study used Particle Swarm Optimization (PSO) to show diverse swarms outperform non-diverse ones, supporting bounded diversity advantage theory (BDAT).
Area of Science:
- Computational intelligence
- Collective behavior
- Personality psychology
Background:
- Bounded Diversity Advantage Theory (BDAT) posits that limited personality diversity improves collective problem-solving.
- Previous research has not computationally tested BDAT mechanisms.
Purpose of the Study:
- To computationally test BDAT using a Particle Swarm Optimization (PSO) testbed.
- To investigate how conscientiousness-like behaviors influence collective problem-solving dynamics.
Main Methods:
- A novel monitoring approach quantified group agreement dynamics in PSO.
- Six diverse and non-diverse swarm compositions were compared on 11 mathematical functions.
- Performance Efficiency Score (PES) balanced error and iterations to evaluate swarm outcomes.
Main Results:
- Diverse swarm compositions demonstrated superior performance compared to non-diverse ones.
- Monitoring revealed that industrious agents drove early convergence, while less industrious agents explored more.
- Observed dynamics align with BDAT predictions regarding bounded diversity and premature convergence.
Conclusions:
- Particle Swarm Optimization (PSO) serves as a viable testbed for BDAT mechanisms.
- Findings support BDAT's core tenets and bridge personality psychology, group processes, and evolutionary perspectives.
- Further research is needed for broader validation of BDAT.
