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.

“It was draconian and complete,” he said. “It’s not like I wanted to just steer away from Trump or shift the conversation. It was like I was a vampire and any photon of Trump would turn me to dust.”

It was just going to be for a few days. But he is now more than a year into knowing almost nothing about American politics. He has managed to become shockingly uninformed during one of the most eventful chapters in modern American history. He is as ignorant as a contemporary citizen could ever hope to be.
