      👇Yep, that “paper” isn’t even wrong. One tragedy of all this is that, at the moment, only the companies can fully study phenomenon such as the behavior of recommendation algorithms. There are some great external studies that do give us a sense—but that’s all we get. Yet.https://twitter.com/random_walker/status/1211262124724510721 …

      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.

      Could we do a proper study of, say, the behavior of recommendation algorithms without the participation of the company? Yes. It would need to be a panel study, and it would be expensive and difficult. It’s doable, but like any complex phenomenon not cheap or simple.

      LOL to anyone pretending to study recommendation algorithms without being logged in. It’s plausible YouTube’s has gotten better – partly because we highlighted the problem when they had their head in the sand. I also don’t think it’s fixable without “sacrificing” some engagement.

      LOL is not the right reaction to this—past work has not found notable differences between logged in and logged out. Yes it would be better to get additional empirical evidence om this q, but this work cannot be dismissed outright

      This from last year similarly shows minimal differences from personalization: https://doi.org/10.1145/3274417

      That’s Google search! Google search has the exact opposite incentive structure of YouTube—to get you on your way as soon as possible to your target as opposed to keeping you on the site. We know from Google that once they got a new rec algorithm few years ago, engagement jumped.

      I think it’s possible that YouTube has improved in this regard. How much? I don’t see why one would do a drive-by anonymous user type study to look into this. It’s just the kind of thing for which we need independent researchers with access the industry data coupled with a panel.

          Drive by is not really fair. Yes they should have done a few tests to illustrate the extent to which personalization could threaten the findings. And yes there’s only so much you can say without all of YouTube, but this strikes me as an important piece of evidence
