Uni Blake explains the problems with anecdotal evidence used by natural gas opponents. While the general public may find anecdotal evidence highly compelling, most scientists are suspicious of data that rests on anecdotes.

The study released recently by Earthworks’ Oil and Gas Accountability Project, “Gas Patch Roulette” is an example.
