Microaggression is a term which some use to refer to unintended discrimination. Psychiatrist and Harvard University professor Chester M. Pierce coined the word microaggression in 1970 to describe insults and dismissals he said he had regularly witnessed non-black Americans inflict on African Americans.
While the term microaggressions has been a part of academic discourse for some time (micro-inequities was coined by an MIT Ph.D. in 1973), it became better known through the popular Tumblr Microaggressions. The Tumblr is a project that aims to highlight the daily microaggressions people encounter through user submitted stories.
