Lethal firearm ownership is deeply polarizing in the United States.
Join Dr. Marcella Alsan for a discussion that shows that beneath this polarization, owners and non-owners share a common objective - safety - but disagree sharply about whether lethal firearms achieve it. Using an original survey of more than 5,400 respondents combined with randomized experiments, she finds that owners feel safe and confident with firearms, while non-owners on balance feel less safe around them and perceive large private costs and social harms. Surprisingly, one-third of non-owners want to acquire one. Persuading owners to disarm appears unrealistic, but safe storage and non-lethal alternatives show promise.
Experiments reveal that information about costs and non-lethal options shifts attitudes - suggesting that shared safety goals could bridge the divide.
