Am I the only one who dislikes this form of presentation, i.e. as a series of tweets?

No, you aren't the only one. It has become even worse now that Twitter will not render without JavaScript enabled. Unfortunately, I still do not know what Berkson's Paradox is because I will not enable JavaScript for Twitter.

Okay, I googled it. A non-hostile site hosts a definition here: https://en.wikipedia.org/wiki/Berkson%27s_paradox

The series of tweets for me just wasn't illuminating and I didn't get what the actual 'paradox' was given the graphs. But my issue was more that the graphs weren't clear in pointing out what I should be looking at.

Wikipedia was much clearer for me, https://en.wikipedia.org/wiki/Berkson's_paradox , but ymmv of course.

Another good statistical foible to be aware of along with Simpson's.

Thank you. Does anyone understand the difference between this and Simpson's paradox?

The latter appears when analyzing subgroups gives a different result than analyzing the pooled data.

The former is about correlations that appear in samples which are not representative of the general population, due to the way that those samples are selected.

From the wikipedia page it seems to be a generalization on sampling below the Nyquist frequency can lead to incorrect interpretation of wave forms but in more dimensions.
