This doesn't actually take into account that the naggee can influence this. As a 12 year old, I remember finally getting so sick of my Dad nagging me to mow the lawn, that I started doing it before he had a chance to.
With my mother this failed miserably. After I gave up on her nagging for someone to do the dishes, she started nagging that the dishes weren't coming out as clean as they should. After I started scrubbing a lot longer and harder she started nagging that the drain and the sink weren't always pristine. After I started cleaning the drain and sink every time I did the dishes she complained the the countertop got wet. After I started drying the countertop, then the kitchen table had crumbs over it. After that, I broke down and had a really bad fight with her, and got her to shut up and just clean whatever it was that bothered her so much in the kitchen.
My mom used to (and occasionally still) do a lot of nagging. By the time I was five years old, I had learned to shut it out. Nagging just does not work over extended time periods unless the other person is completely submissive.
