The economist — an outcast within his field over his studies supporting more relaxed gun laws — said a recent academic paper blaming American gun culture for its high rate of mass shootings “is one of the biggest hoaxes of this century.”

The paper in question — a 2016 study by University of Alabama Criminology Professor Adam Lankford — found from 1966 through 2012, Americans perpetrated 31 percent of all mass shootings, despite only accounting for less than 5 percent of the world’s population.
