Last July, Politifact introduced scorecards to rank the truthfulness of
statements made on major news networks.
Each of the news networks that we routinely follow -- ABC, CBS, FOX, NBC/MSNBC and CNN -- now has a scorecard that breaks down that network’s performance on the Truth-O-Meter. The scorecard tallies each statement we fact-check on that network and groups the rulings by percentage. [...]
Our scorecards only include statements made on that network by a pundit or a host or paid staffer. That means they do not include statements made by elected leaders, candidates or party officials. We feel it’s difficult to hold a network accountable for the comments of a politician.
Last September, the scorecard found that—surprise, surprise—
Fox News had the worst record for truth-telling.
Right now, you can look at the MSNBC file, which also includes NBC, and see how that network’s pundits and on-air talent stand. For instance, currently 45 percent of the claims we’ve checked from NBC and MSNBC pundits and on-air personalities have been rated Mostly False, False or Pants on Fire.
At Fox and Fox News Channel, that same number is now 58 percent. At CNN, it’s 22 percent.
Wow. Granted that MSNBC's record isn't fabulous either, but
more than half the statements at Fox are false or "mostly false." You'd think they couldn't get much worse than that. However, their most recent scorecards released this month show Fox has somehow managed to
outdo themselves yet again.
At Fox and Fox News, 10 percent of the claims we’ve rated have been True, 11 percent Mostly True, 18 percent Half True, 21 percent Mostly False, 31 percent False and nine percent Pants on Fire.
That means about 60 percent of the claims we’ve checked have been rated Mostly False or worse.
