The funniest thing Rob ever did was to make dozens of copies of his grocery store loyalty card bar-code printed onto peel&stick paper. He then mailed them out to anyone wanting to play along. Participants then pasted Rob’s loyalty card bar-code onto their cards.
Suddenly the grocery chain had interesting data on Rob, suggesting strange buying and travel habits.

Sounds perfect for the MMP actually. We’ve already had some stuff like that now and then.
I was published in either that or the Annals of Irreproducible results many, many years ago. I think the Annals came first, then handed it over to a new editor, then there was a lawsuit about who owned the title, and now there’s the JIR.
However, if people are going to conduct double blind experiement with children I think it’s only responsible to do a design of experiments and make them do the math. Student’s T-test for everyone!
Uhhhh, yeaaaahhh, but my niece is 30 years old…
