“‘Fact-checking’ fact checkers: A data-driven approach,” a 22-page October research article from the Harvard Kennedy School Misinformation Review, examined practices of U.S. fact-checking organizations Snopes, PolitiFact and Logically, along with The Australian Associated Press.

Sian Lee, Aiping Xiong, Harseung Seo and Dongwon Lee of Penn State University’s College of Information Sciences and Technology did the peer-reviewed research.

The Penn State researchers found U.S. fact-checking spikes during major news events. In recent years, that was during the COVID-19 pandemic and the 2020 presidential election. Further, the researchers said, misinformation’s spread can mislead and harm people and society.

The researchers examined 11,639 fact-checking articles from Snopes and 10,710 from PolitiFact from Jan. 1, 2016, to Aug. 31, 2022. They found Snopes checked more “real claims” — claims that rate true or mostly true — with 28.7% versus 11% for PolitiFact.

Looking widely, the researchers found high agreement when Snopes and PolitiFact probed the same information. Of 749 matching claims (examining the same information), 521 received identical ratings and 228 (30.4%) had diverging ratings. But, the researchers found nuances caused nearly all of these divergent verdicts — granularity of ratings (Snopes and PolitiFact scales differ slightly); differences in focus; differences in fact-checked information and the different timing of the fact-checks.

Adjusting for these systematic discrepancies, Penn State’s researchers found just one conflicting rating among the 749 matching claims.

Drosophila Mild Traumatic Brain Injury (mTBI) Model. TBI methods used for this study have been previously described [18,19]. Briefly, pretreated flies were anesthetized, placed in 2 mL screw cap tubes (10 flies/tube), and allowed to recover before being placed in the Omni Bead Ruptor-24 homogenizer (Omni International, Kennesaw, GA). Adult control and treated flies were pretreated for 3 days with different compounds before exposure to 10 mild trauma bouts (mild traumatic brain injury [mTBI] 10x, 2.1 m/s) at 1 week of age [19]. Following injury, flies were returned to vials containing treated media and maintained using standard culturing conditions. The number of dead flies was counted starting 48 h following trauma and then 3 times weekly for the remainder of the study, and the data were used to establish mortality indexes (MI) and longevity profiles. The percentage of dead flies described as weekly MI of treated cohorts after mTBI (10x) exposure for 1, 2 and 3 weeks was calculated. Data were normalized for total flies/cohort. Each condition includes between 110 and 235 flies (n = 110–235).

Bead beater sure would scramble my marbles.

Same people, they've been making biodegradable footwear for a bit now.
