The problem is that people will express classic hindsight bias no matter which way the result turns out. Let's say you're studying relationships and researching whether having similar interests is better or worse than having dissimilar interests. If you spend a million dollars on a comprehensive longitudinal study and find the former, the public will lambast you for rediscovering the obvious result that "two of a feather flock together". But if you find the latter, you'll be mocked for rediscovering the simple fact that "opposites attract". On the topic of self-control, I'm actually surprised that the results turned out the way they did. I would have expected the opposite result; that "exercising" your discipline solves the problem once and for all, while reducing temptation is just asking for a relapse when temptation inevitably presents itself again.
