Academics depict the peer-review process as the gold standard for intellectual honesty, ensuring published scholarly work is unbiased and accurate. But ideological conformity makes peer review a far thinner defense than advertised.
In January I published a book about the mental-health and violence risks of cannabis. Several dozen scholars signed a petition expressing in unison their objection to my work. Thus I’ve recently spent an inordinate amount of time reading papers seeking to prove that marijuana is a cure-all whose deleterious consequences are a figment of our collective imagination. The shoddiness of much of the work has shocked me.
Example: Driving deaths have risen more than 30% in Colorado and Washington, the first states to legalize marijuana for recreational use, since dispensaries opened there in 2014. That rise is more than double the national change. The Insurance Institute for Highway Safety reported in October that the number of vehicle accidents overall were up faster in legalized states than the rest of the nation.
