One of the paradoxes of racial discrimination is the way it can remain obscured even to the people to whom it’s happening. Here’s an example: In an ambitious, novel studyconducted by the Urban Institute a few years ago, researchers sent actors with similar financial credentials to the same real estate or rental offices to ask about buying or renting a home or apartment. In the end, no matter where they were sent, the actors of color were shown fewer homes and offered fewer discounts on rent or mortgages than those who were white.
