Before blaming me for not reading the article, maybe read my whole comment? I listed 2 effects. Yes, mean versus median is one. The other is a cognitive bias related to how humans estimate percentages.
Medians showing the same effect but reduced is exactly what I would expect when you account for one of the two phenomena but not the other.
You still clearly did not read the whole post, otherwise you would not have used the mean-median difference as an example.
That’s the more charitable intetpretation, by the way, the alternative is you did read it, knew it featured the median data points, and then acted as if it didn’t, ie, intentionally misrepresented.
Also, what you’re just asserting that round number bias is essentially uncontrolled for here? But you present 0 evidence of this.
That could be the case, but you have presented absolutely no evidence that that is the case.
As an econometrician, have you not heard of Kahneman and Tversky? That boggles my mind. Look up round number bias, and regression toward 50%, and maybe read Judgment Under Uncertainty: Heuristics and Biases.

These are fairly big survey/pollster people.
They probably know to account for that.

We don’t know for certain though, because they do not extensively detail their methodologies in their post.
… but its… misleading to present the entire thing as being juat an artefact of not accounting for round number bias, or some other bias.
I’m an econometrician, it bugs me when people criticize statistics in invalid ways.
If you wanna wade into lies, damned lies, and statistics… arm yourself well, or, be a bit more humble.
