Layers of Editors: How fast is PolitiFact's stupidity growing?

Uh-oh! PolitiFact's incompetence unfairly harmed a Democrat again! This time it was hapless Joe Biden who ended up with the short straw by PolitiFact's blinkered judgment.

PolitiFact explained that over the past 10 years the number of Hispanics increased by about 10 million, while the number of Asian Americans went up by 5.2 million.

Why is an increase, on average, of 520,000 per year a faster increase than about 1 million per year?

PolitiFact explains, sort of:

Biden said "the fastest-growing population in the United States is Hispanic." That’s incorrect: The fastest-growing group is Asian Americans, with Hispanics ranking second. Hispanics did record the largest numerical increase in population of any group between 2010 and 2019, but that’s a different measure than "fastest growing."

Instead of recognizing more than one measure of "fastest-growing," PolitiFact arbitrarily accepts one measure while rejecting the other.

But an increase of 1 million per year on average is a rate of growth, and arguably more useful than measuring rate of growth as a percentage of an existing population.

We pointed out on Twitter that PolitiFact's reasoning would suggest that a one foot tall tree that doubles in size is growing faster than a 50 foot tall tree that grows two feet during the same span of time.

Sure, the first tree may surpass the second tree in size if it continues to double in size year-by-year. But it will never happen unless the first tree starts to surpass the second tree in the number of inches of growth per year.

Never.

And the math works similarly for population growth. Unless Asian Americans start adding more population in absolute numbers than do Hispanics, the number of Hispanics will forever be greater than the number of Asian Americans. Forever. In fact, Asian Americans will not start closing the gap between the two populations until they start adding more people in raw numbers rather than merely in terms of percentage.

So who do these fact checkers think they are?


Update March 8, 2021: Added the link to the PolitiFact "fact check" in the second paragraph.

The ongoing stupidity of PolitiFact California

PolitiFact on the whole stinks at fact-checking, but PolitiFact California is special. We don't use the word "stupid" lightly, but PolitiFact California has pried it from our lips multiple times already over its comparatively short lifespan.

PolitiFact's latest affront to reason comes from the following PolitiFact California (@CAPolitiFact) tweet:

Odds of fatal terror attack in U.S. by a refugee? 3.6 billion to 1. Our 2nd most popular fact-check (so far) of 2017 https://t.co/vZCUrauEZo pic.twitter.com/1yEOftynzp

The original fact check was stupid enough, but PolitiFact California's tweet twists that train wreck into an unrecognizable heap of metal.

• The fact check discusses the (per year) odds of falling victim to a fatal terror attack committed by a refugee.
• The tweet trumpets the (per year) odds of a fatal attack occurring.

The different claims require totally different calculations, and the fact that the tweet confused one claim for the other helps show how stupid it was to take the original fact-checked claim seriously in the first place.

The original claim said "The chances of being killed by a refugee committing a terrorist act is 1 in 3.6 billion." PolitiFact forgave the speaker for omitting "American" and "per year." Whatever.

But using the same data used to justify that claim, the per year chances of a fatal attack on an American (national risk, not personal) by a refugee occurring is 1 in 13.3. That figure comes from taking number of fatal attacks by refugees (3) and dividing by the number of years (40) covered by the data. Population numbers do not figure in the second calculation, unlike the first.

That outcome does a great deal to show the silliness of the original claim, which a responsible fact checker would have pointed out by giving more emphasis to the sensible expert from the Center on Immigration Studies:

Mark Krikorian, executive director of the Center for Immigration Studies, a think tank that favors stricter immigration policies, said the "one in 3.6 billion" statistic from the Cato study includes too many qualifiers. Notably, he said, it excludes terrorist attacks by refugees that did not kill anyone and those "we’ll never know about" foiled by law enforcement.

"It’s not that it’s wrong," Krikorian said of the Cato study, but its author "is doing everything he can to shrink the problem."

Krikorian stated the essence of what the fact check should have found if PolitiFact California wasn't stupid.



Correction July 21, 2017: Fixed typo where "bit" was substituted for "but" in the opening paragraph.
Clarification July 21, 2017: Added "(national risk, not personal)" to the eighth paragraph to enhance the clarity of the argument
