Rock paper scissors incorporated into an evolutionary game has been used for modelling natural processes in the study of [[ecology]].<ref>Allesina and Levine, "A competitive network theory of species diversity", Proceedings of the National Academy of Sciences, 2011</ref> 
Using [[experimental economics]] methods, scientists have used RPS games to test human social evolutionary dynamical behaviours in laboratories. The social cyclic behaviours, predicted by evolutionary game theory, have been observed in various laboratory experiments.<ref>{{cite journal | last1=Hoffman | first1=M | last2=Suetens | first2=S | last3=Gneezy | first3=U | last4=Nowak | first4=M | year=2015 | title=An experimental investigation of evolutionary dynamics in the Rock-Paper-Scissors game | journal=Scientific Reports | volume=5 |  page=8817 | doi=10.1038/srep08817  |bibcode=2015NatSR...5E8817H | pmid=25743257 | pmc=4351537}}</ref><ref>{{cite journal | last1=Cason | first1=T | last2=Friedman | first2=D | last3=Hopkins | first3=E | year=2014 | title=Cycles and Instability in a Rock–Paper–Scissors Population Game: A Continuous Time Experiment | journal=Review of Economic Studies | volume=81 | issue=1 | pages=112–136 | doi=10.1093/restud/rdt023 | citeseerx=10.1.1.261.650 }}</ref>
