This skepticism is widely shared, and one way for creative-writing programs to handle it is simply to concede the point. The University of Iowa Writers’ Workshop is the most renowned creative-writing program in the world. Sixteen Pulitzer Prize winners and three recent Poet Laureates are graduates of the program. But the school’s official position is that the school had nothing to do with it. “The fact that the Workshop can claim as alumni nationally and internationally prominent poets, novelists, and short story writers is, we believe, more the result of what they brought here than of what they gained from us,” the Iowa Web site explains. Iowa merely admits people who are really good at writing; it puts them up for two years; and then, like the Wizard of Oz, it gives them a diploma. “We continue to look for the most promising talent in the country,” the school says, “in our conviction that writing cannot be taught but that writers can be encouraged.” . . .
