Not enough talk about evidence-based medicine in current "debate"

In an editorial in the Sacramento Bee today, Shannon Brownlee and Michael Wilkes write:

"Why isn't the issue of medical evidence front and center in the health care debate? Maybe because doctors have not always been truthful in telling people what they know and don't know. Many physicians are either unwilling or unable to take the time needed to fully explain where uncertainty exists. As a result, 65 percent of California voters are under the mistaken impression that most or nearly all of the health care they receive is backed up by scientific studies."
