What I agree with: actively overcoming your procrastination has more to do with dealing with the obstacles that cause you to procrastinate in the first place. For example, if you’re procrastinating because of your anxiety, dealing with your anxiety is generally going to be a much more effective approach than trying to increase your self-control.
What I disagree with: self-control is without a doubt one of the psychological mechanisms that play a role in our procrastination. That doesn’t mean that we should focus on it when we’re trying to help people stop procrastinating, but it does mean that it's important to understand the role that it plays.
If you look at the research papers that this article mentions, this is something that the researchers themselves are saying. For instance, in the first paper, Sirois and Pychyl say that: “if we have a great deal of self-discipline and dutifulness, commonly associated with the Big Five trait of Conscientiousness… we may exert the self-control necessary to engage in the task in a timely manner despite the lack of immediate reward or the negative mood that the task elicits.”
As such, while I think it’s reasonable for the article to conclude that when it comes to dealing with procrastination, your focus shouldn’t necessarily be on your self-control, I believe that it’s misleading for the title to claim that procrastination has “nothing to do with self-control”, when self-control clearly does play a role in this process.
