==== Personality conformity ====
It is considered difficult to study emotions in animals when humans could not communicate with them. One way to identify animal [[personality]] traits is to observe the consistency of the individual's behavior over time and circumstances.<ref>{{Cite journal|last1=Both|first1=Christiaan|last2=Dingemanse|first2=Niels J.|last3=Drent|first3=Piet J.|last4=Tinbergen|first4=Joost M.|date=July 2005|title=Pairs of extreme avian personalities have highest reproductive success|journal=Journal of Animal Ecology|volume=74|issue=4|pages=667–674|doi=10.1111/j.1365-2656.2005.00962.x|issn=0021-8790|doi-access=free|bibcode=2005JAnEc..74..667B }}</ref><ref>{{Cite journal|last=Gosling|first=Samuel D.|date=2001|title=From mice to men: What can we learn about personality from animal research?|url=http://doi.apa.org/getdoi.cfm?doi=10.1037/0033-2909.127.1.45|journal=Psychological Bulletin|volume=127|issue=1|pages=45–86|doi=10.1037/0033-2909.127.1.45|pmid=11271756|issn=1939-1455}}</ref> For group-living species, there are two opposing hypotheses regarding the assortment of personalities within a group: the social niche specialization hypothesis, and the conformity hypothesis. To test these two hypotheses, McCune et al. (2018) performed an experiment on the boldness of two species in Corvidae: the [[Mexican Jay]] and [[California Scrub-Jay]]. Their results confirmed the conformity hypothesis, supported by the significant differences in the group effects.<ref>{{Cite journal|last1=Bergmüller|first1=Ralph|last2=Taborsky|first2=Michael|date=September 2010|title=Animal personality due to social niche specialisation|url=https://linkinghub.elsevier.com/retrieve/pii/S0169534710001515|journal=Trends in Ecology & Evolution|volume=25|issue=9|pages=504–511|doi=10.1016/j.tree.2010.06.012|pmid=20638151|bibcode=2010TEcoE..25..504B }}</ref>
