A new paper has been making the rounds with the intriguing claim that YouTube has a *de-radicalizing* influence. https://arxiv.org/abs/1912.11211 Having read the paper, I wanted to call it wrong, but that would give the paper too much credit, because it is not even wrong. Let me explain.

Sidenote: the first author has been on a diatribe about the media, even in the thread introducing the paper. It doesn’t undermine the paper by itself, but given that they disingenuously exclude how radicalization might actually work, it… raises questions.https://twitter.com/mark_ledwich/status/1210743217982803970 …

Others have pointed out many more limitations of the paper, including the fact that it claims to refute years of allegations of radicalization using late-2019 measurements. Sure, but that’s a bit like pointing out typos in the article that announced "Dewey Defeats Truman".

Incidentally, I spent about a year studying YouTube radicalization with several students. We dismissed simplistic research designs (like the one in the paper) by about week 2, and realized that the phenomenon results from users/the algorithm/video creators adapting to each other.

Let’s not forget: the peddlers of extreme content adversarially navigate YouTube’s algorithm, optimizing the clickbaitiness of their video thumbnails and titles, while reputable sources attempt to maintain some semblance of impartiality. (None of this is modeled in the paper.)

After tussling with these complexities, my students and I ended up with nothing publishable because we realized that there’s no good way for external researchers to quantitatively study radicalization. I think YouTube can study it internally, but only in a very limited way.

If you’re wondering how such a widely discussed problem has attracted so little scientific study before this paper, that’s exactly why. Many have tried, but chose to say nothing rather than publish meaningless results, leaving the field open for authors with lower standards.

In our data-driven world, the claim that we don’t have a good way to study something quantitatively may sound shocking. The reality even worse — in many cases we don’t even have the vocabulary to ask meaningful quantitative *questions* about complex socio-technical systems.

Consider the paper’s definition of radicalization: "YouTube’s algorithm [exposes users] to more extreme content than they would otherwise." Savvy readers are probably screaming: There is no "otherwise"! There is no YouTube without the algorithm! There is no neutral!

That’s the note on which I’d like to end: a plea to consider that the available quantitative methods can’t answer everything. And I want to thank the journalists who’ve been doing the next best thing — telling the stories of people led down a rabbit hole by YouTube’s algorithm.

Even worst, they were using the youtube API. we made an empirical test to discredit this approach, by comparing: - youtube API results - result with 10 people logged out (clean cookies) - result with 10 people logged:pic.twitter.com/bDE5Q25FCr
