The Man Who Knew Too Little

GLOUSTER, Ohio — At first, the experiment didn’t have a name.

Right after the election, Erik Hagerman decided he’d take a break from reading about the hoopla of politics.

Donald Trump’s victory shook him. Badly. And so Mr. Hagerman developed his own eccentric experiment, one that was part silent protest, part coping mechanism, part extreme self-care plan.

He swore that he would avoid learning about anything that happened to America after Nov. 8, 2016.
