As the Obama era is about to begin, four brilliant, accomplished people — Harvard types, all of them — consider racism in America in “Smart People” by playwright Lydia R. Diamond. While the hot-button issue is difficult for these intellectuals to articulate, it manifests concretely through the characters' relationships with each other. Kenny Leon directs the production by Second Stage Theatre, featuring a strong cast comprised of Mahershala Ali, Joshua Jackson, Anne Son and Tessa Thompson. 

New York Times theater critic Charles Isherwood checks it out to see if the play is as smart as the characters in it.
