Oops, you’re right that my link does not mention controlled experiments. A few controlled experiments are instead mentioned in other sections of the book on techniques applicable to a greater variety of behavior change goals.
Unfortunately, the author of Psychological Self-Helpdied last year, and his book has not been updated much in the past decade. Of course, more work on procrastination has been done in recent years, though I’m not sure if it is collected nicely anywhere.
