If I have to read one more shorthand description of the famous "Marshmallow Study" in a social science book, I'm going to explode.
You know why?
They always miss something.
Marshmallows are delicious.
For real though, I hate how it has become a proxy for so much lazy analysis. I've long considered creating a "marshmallow index" that shows how far into the book the study is cited. The sooner, and the more reliant whatever the argument is on the necessity of looking at the study, the higher the number. The higher the number, the more worthless the book.
This is all preliminary.
