Yes I think that's a general feeling! Still, the act of sharing pushes one to improve?

As long as results are correct, it should be fine? And if there were errors, better that they can be caught than hidden forever?

Oh yes, I was thinking of honest papers from honest authors. Made up papers are a different ugly beast...

Agree. Still I think it's better to have it published than hidden? Helps interpret the paper.

Also I like to think that asking ourselves 'is it good enough?' before publishing would increase the final quality rather than deciding beforehand not to share?

97% of the papers archived the data but only 35% archived the code.

Most people are writing code but not sharing it. Time to bring up this again: scispace.com/pdf/publish-... (and if the code isn't good enough yet, maybe it's too early to publish the paper)

Per protocol analysis strikes again!

Folks, if you randomize but then donβ€˜t analyze some of the people who got randomized (maybe because they didn’t adhere to instructions, maybe because they dropped out), randomization will no longer do all the heavy causal inference lifting.

If you haven't yet changed how you teach and evaluate thanks to AI, you probably need to. This is not something that educators asked to happen, but it is worth noting what is out there - in this case an OpenClaw tool designed to cheat.

The political effects of X's feed algorithm

Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects'. Here we present results from a 2023 field experiment on Elon Musk's platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects.
Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users' feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X's algorithm has persistent effects on users' current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship.

A new paper shows that less than 2 months of exposure to Twitter’s algorithmic feed significantly shifts people’s political views to the right.

Moving from chronological feed to the algorithmic feed also increases engagement.

This is one of the most concerning papers I’ve read in awhile.

You usually don’t want to test for fit to a Normal distribution. If you do, you usually don’t care primarily about the alternatives to which the Shapiro-Wilk test is sensitive. Unless the conclusion is very clear, pre-testing is going to completely munt your subsequent tests. And if the conclusion is clear then you can look at the qq-plot; you don’t need to get maths to look at it for you, and you might learn something else about the data.

Periodic reminder that we should avoid testing the Normality of the response variable.

For a linear model, what matters is the Normality of residuals (and not that much). Visual checks better than test. #statistics
