Using an evolutionary theoretic approach to collective decision making, agent\u2010based simulations were conducted to investigate how human collective decision making would be affected by the agents\u2019 diversity in problem understanding and\/or behavior in discussion, as well as by their social network structure. Simulation results indicated that groups with consistent problem understanding tended to produce higher utility values of ideas and displayed better decision convergence, but only if there was no group\u2010level bias in collective problem understanding. Simulation results also indicated the importance of balance between selection\u2010oriented (i.e., exploitative) and variation\u2010oriented (i.e., explorative) behaviors in discussion to achieve quality final decisions. Expanding the group size and introducing nontrivial social network structure generally improved the quality of ideas at the cost of decision convergence. Simulations with different social network topologies revealed collective decision making on small\u2010world networks with high local clustering tended to achieve highest decision quality more often than on random or scale\u2010free networks. Implications of this evolutionary theory and simulation approach for future managerial research on collective, group, and multilevel decision making are discussed.<\/jats:p>","DOI":"10.1155\/2019\/7591072","type":"journal-article","created":{"date-parts":[[2019,3,20]],"date-time":"2019-03-20T23:32:14Z","timestamp":1553124734000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Diversity and Social Network Structure in Collective Decision Making: Evolutionary Perspectives with Agent\u2010Based Simulations"],"prefix":"10.1155","volume":"2019","author":[{"given":"Shelley D.","family":"Dionne","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2670-5864","authenticated-orcid":false,"given":"Hiroki","family":"Sayama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Francis J.","family":"Yammarino","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2019,3,20]]},"reference":[{"key":"e_1_2_10_1_2","doi-asserted-by":"publisher","DOI":"10.1287\/mnsc.1090.1031"},{"key":"e_1_2_10_2_2","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.psych.55.090902.142009"},{"key":"e_1_2_10_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.leaqua.2010.10.007"},{"key":"e_1_2_10_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.leaqua.2016.01.001"},{"key":"e_1_2_10_5_2","doi-asserted-by":"publisher","DOI":"10.1002\/job.2301"},{"key":"e_1_2_10_6_2","doi-asserted-by":"publisher","DOI":"10.1177\/2041386618756063"},{"key":"e_1_2_10_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/MIS.2003.1249167"},{"key":"e_1_2_10_8_2","doi-asserted-by":"publisher","DOI":"10.1007\/3-540-32834-3"},{"key":"e_1_2_10_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.cirp.2012.05.001"},{"key":"e_1_2_10_10_2","unstructured":"O\u2019ReillyT.
