The title says that procrastination has "nothing to do with self-control", which is obviously an appealing sentiment.
However, the first paper that they reference says that "...if we have a great deal of self-discipline and dutifulness... 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. Procrastination, however, is the lack of this self-control, whether as a state or trait. Procrastination is the self-regulatory failure of not exerting the self-control necessary for task engagement... this failure at self-control may be the direct result of a focus on regulating moods and feeling states in the short term."
Overall, a better argument would be that a lack of self-control isn't the driving force behind our decision to procrastinate. Rather, what causes us to procrastinate are things such as anxiety or fear of failure, and a high degree of self-control is what allows us to overcome these issues.
