Micro inequity examples

In 1973 Mary Rowe, while working for the President and Chancellor at MIT, coined the notion of micro-inequities, which she defined as “apparently small events which are often ephemeral and hard-to-prove, events which are covert, often unintentional, frequently unrecognized by the perpetrator, which occur wherever people are perceived to be ‘different.’ " Examples of micro-inequities include:
checking emails or texting during a face-to-face conversation
consistently mispronouncing a person's name
interrupting a person mid-sentence
making eye-contact only with males while talking to a group containing both males and females
taking more questions from men than women
confusing a person of a certain ethnicity with another person of the same ethnicity
rolling your eyes
sighing loudly
raising your voice, even though the other person has no difficulties hearing you
mentioning the achievements of some people at a meeting but not others whose achievements are equally relevant
consistently ignoring a person's emails for no good reason
only reading half of a person's email and then asking the person about the content later
making jokes aimed at certain minority groups
being completely unpredictable in your grading of certain people's term papers
issuing invitations that are uncomfortable for certain groups (“Please feel free to bring your wife,” "There is a link below to childcare options for female speakers who plan to bring their children," “There will be a belly-dancer at the party,“ "Our annual Christmas party will be held on December 18,” "Please bring pork chops to the potluck dinner")
