FactChecking Science Claims in 2017

In our roundup of 2016 claims, we hypothesized that SciCheck would have no dearth of false and misleading claims to cover in 2017. That proved true. Politicians kept us busy. As 2017 comes to a close, we present the most notable claims about science from this year.

Sessions Wrong About Drugged Driving

Attorney General Jeff Sessions claimed that more car accidents were “caused” by drugs than alcohol for the first time in 2016. But the report his office cited as support didn’t show that.
