That’s fair, though personally I’m kindof glad they did. “Signal is a secure messaging app” is a lot easier to explain to non-tech-savvy people than “Signal is a secure messaging app, as long as you are messaging someone who is using Signal too. It can also send regular texts but they can’t be encrypted.” Leaving that nuance out would have left people texting with a false assumption of security, but I lost several people explaining it because it “sounds complicated”.
Hooo boy. This article is wildly misrepresenting both the study and it’s findings.
Most critically, the study itself does not claim that differences between these demographics are representative. That portion is looking at differences in the sample pool before/after the test, to examine its potential for “training” people to spot fake news (this had mixed results, which they acknowledge). This article, ironically, is spreading misinformation about the study itself, and doing the researchers and its readers a great disservice.
