Editing Collective memory (section)

===Social representations of history ===
Research on collective memory has compared how different social groups form their own representations of history and how such collective memories can impact ideals, values, behaviors and vice versa.  Research has proposed that groups form social representations of history in order to develop their own social identity, as well as to evaluate the past, often in order to prevent past patterns of conflict and error from being repeated.  Research has also compared differences in recollections of historical events, such as the examples given earlier when comparing history and collective memory.<ref name=":1" />

Differences in collective memories between social groups, such as nations or states, have been attributed to collective narcissism and egocentric/ethnocentric bias. In one related study where participants from 35 countries were questioned about their country's contribution to world history and provided a percentage estimation from 0% to 100%, evidence for collective narcissism was found as many countries gave responses exaggerating their country's contribution. In another study where Americans from 50 states were asked similar questions regarding their state's contribution to the history of the United States, patterns of overestimation and collective narcissism were also found.<ref>{{Cite journal|date=2018-12-01|title=We Made History: Citizens of 35 Countries Overestimate Their Nation's Role in World History|journal=Journal of Applied Research in Memory and Cognition|volume=7|issue=4|pages=521–528|doi=10.1016/j.jarmac.2018.05.006|issn=2211-3681|last1=Zaromb|first1=Franklin M.|last2=Liu|first2=James H.|last3=Páez|first3=Dario|last4=Hanke|first4=Katja|last5=Putnam|first5=Adam L.|last6=Roediger|first6=Henry L.|s2cid=158214873 }}</ref><ref>{{Cite web|url=https://www.scientificamerican.com/article/the-power-of-collective-memory/|title=The Power of Collective Memory|last=DeSoto|first=Henry L.
