Thank you. I think I have never seen something that comes quite so blatantly and obviously into the category of
cargo cult science. I remember first coming across the term on this forum, and having to think carefully about what it might mean. For all my interest in pseudoscience, I had never seen that term before, and presumed the poster must have made it up. I was very impressed when I realised what a nice distinction it was. But it was apparently first used by Richard Feynmann, and deserves to be better known.

I wanted to do a joke about a t-test, but I read the article and it had already been done.

Thoroughly depressing.
Using a bar chart to plot a distribution of data is f.cking stupid. Plot the actual data, or at least a violin or box plot or something.

Violin plots are best, because they display the actual distribution, and inevitably look a bit Georgia O'Keeffe.

Might start calling them O'Keeffe plots

I tend to prefer normalised probability plots, but yes.
I have converted about half my colleagues to those.

There is an R package for everything, now including correctly fitting Ts as error bars, via the wonderfully named geom_terrorbar() function:
