Former NPR CEO Ken Stern, hoping to break out of his liberal bubble, spent a year with conservatives and ended up changing his mind about gun control legislation.

Stern traveled around the country with Republicans and conservatives to write his new book “Republican Like Me,” and explained during an MSNBC interview that his research substantially changed his views on firearms in the United States.

“I started off knowing and believing we all have a confirmation bias. We all take our views and signals from others,” Stern said. “How could I be right about everything?”

“I did change my views on guns. … Gun homicides, death by guns in this country, has gone down in this country by more than half over the past 25 years,” he explained. “At the same time the number of guns have gone up.”

“It’s clear that we know how to drive down gun murders without gun control,” he said. “And the question is why are we talking about gun control when there are other things that we’ve been doing for 25 years that actually have reduced murders in this country by an extraordinary amount.”
