Colonel finds plenty of supporting evidence for confirmation bias report

Filed · 1540

FORT CAMPBELL, Ky. — Col. Robert Root has found overwhelming evidence to support his latest Officer Professional Development brief on the topic of confirmation bias, sources confirmed Tuesday.

Root is preparing a series of OPDs on the subject of rhetorical fallacies, cognitive biases and cliches. Luckily, he doesn’t have to cast a wide net to capture a plethora of examples.

“I wasn’t even doing Wikipedia,” said Root, licking his lips for the 80th time in one minute, “and I found a bunch of examples of confirmation bias right in my own battalion.”

Root, the commander of the 101st Division Artillery, discussed his overarching work on the OPD series with Duffel Blog.
