For years, PolitiFact Bias has tracked the proportion of false ("False" plus "Pants on Fire") statements PolitiFact rated "Pants on Fire." As PolitiFact has never established an objective distinction between the two ratings, we infer that the difference between the two is substantially or wholly subjective. That makes this dividing line perhaps the best means of using PolitiFact's own ratings to measure its political bias.
As we are looking at proportions and not raw numbers for the bias measurement, the results cannot be dismissed on the basis that Republicans supposedly lie more.
The Tale of the Tape in 2024
Graphs-a-plenty this year!
We'll start with the dual graph of the PoF Bias number along with the story selection proportion number. The PoF Bias number could be expressed either of two ways. As the numbers pretty consistently have show an anti-Republican/pro-Democrat bias, this number shows that anti-Republican bias when the number is greater than 1. Using this option a PoF Bias Number less than 1 shows the PoF bias harmed Democrats. Our chart shows that occurring for four different years (2007, 2011, 2013, 2015). But it's important to point out that the state franchises accounted for the apparent relative evenhandedness for the latter three years. We tracked PolitiFact National separately, and only 2007 and 2017 showed the anti-Democrat bias. The year 2007 counts as a statistical anomaly, we would say. PolitiFact treated the "Pants on Fire" rating as a joke at first.
The chart shows that after 2007 Republicans consistently had more false ratings than Democrats. In 2024 that preference for GOP falsehoods fell just short of the record for 2020. For both years, PolitiFact gave the GOP more than five times the number of false ratings it gave Democrats.
Because Republicans lie more?
Not so fast! Here's where the PoF Bias number shows its value. The PoF Bias number compares the percentages of false statements rated "Pants on Fire" for each party. PolitiFact has never offered an objective means of separating ridiculously false statements from those that are merely false. As the number represents a proportion, it is immune from influence by the sheer number of false ratings. Put another way, it's entirely independent of the Selection Proportion number.
In 2024, PolitiFact was over six times more likely to (subjectively rate a Republican false claim "Pants on Fire" than a false claim from a Democrat. That figure easily eclipsed the old record of 4.58 times more likely set in 2020.
Democrats Lie Less?
PolitiFact encountered a similar distaste for giving Democrats false ratings of any kind. "False" and "Pants on Fire" combined fell from a peak of 135 in 2012 to 25 in 2024. That figure was the lowest for any presidential election year over PolitiFact's entire history.
