Intermittent Variable Reinforcement

You might send out regular email marketing campaigns to promote your web site.

Kathy Sierra reminded me of an experiment by Burrhus Skinner that showed that "behaviour that is reinforced intermittently is much more difficult to extinguish than behaviour that is reinforced continuously."

If you send these out once a week at the same time every week to achieve a desired behaviour (e.g. visiting your web site), you should change this so they go out at a different time every week. Your users won't forget about your web site if you stop sending the campaigns.

Perhaps someone could write an application that intercepts email that is automatically generated at a fixed time every week on its way out from a server and sends it at a random time up to a week later...
