From time to time I read an article about the Baumeister cookies Vs Radish experiment.
the last time was about planking
The experiment goes as follow:
It's from 1998, and people still bring these up.
I was totally bafled by the result. 10 less minute of effort on average, that's huge.
But then it hit me. It prove Nothing about willpower.
If you propose radish when cookie are available, you're mean. No wonder people didnt want to do your stupid puzzle afterward.
And those who were treated with cookie would show their gratitude by trying harder on the puzzle. The study is irrelevant, with a bad procedure.
It only prove people reciprocate (no cookie = I wont work for you)
Why it come again, and again. I think it's because we want to hear that. We want to believe willpower is REALLY a limited resource we need to manage.
This way we can do less with a good justification.
I find willpower self-perpetuating. The more definitive effort and energy I put into something, the more that feeds back into a drive to keep going. Willpower is limited only if its thought of as some divine quality the comes and goes as it pleases. It all just goes back to the old 'starting is hardest part'.
A prime example is the essay I'm writing at the moment. I spent a good 5 or so hours, give or take, finding research that supported my thesis. Then it came to finding sources that opposed it. I spent maybe 4 hours without finding anything useful to me. If I hadn't already spent 5 hours good work on it, I most likely would've given up and thought of different idea. But because I had already put in that effort, it was easier, or perhaps I was more naturally inclined, to maintain that drive. It paid off too because I found all the stuff I needed. My Google-fu skills need sharpening I think.
