Think procrastination hurts? Harvard says you can use it to ace your exams

For students, exams are often a period of anxiety and long study hours. Conventional wisdom views procrastination as a barrier to success, a habit that reduces focus and productivity. Yet research backed by Harvard University suggests a different perspective. Adam Grant, professor of management and psychology at the Wharton School, has found that procrastination can, in certain cases, improve creativity and problem-solving. By delaying tasks strategically, students can use their natural cognitive processes to develop more original solutions.

Adam Grant cites an experiment by Jihae Shin, now a professor at the University of Wisconsin. Participants were asked to generate new business ideas. Some started immediately, while others delayed by playing games such as Minesweeper or Solitaire. Independent evaluators rated the ideas, and those who delayed produced ideas that were 28% more creative. The study shows that procrastination can support divergent thinking rather than just avoiding work.

Here are five research-backed ways students can use procrastination to their advantage during exams.

Some students start and finish tasks immediately. Grant calls this ‘precrastination’. For them, introducing a pause can improve thinking. Before completing revision or practice problems, take a short break or switch to a different activity. Returning to the work can reveal new connections and insights.

Students who delay work may face stress. Harvard-backed research offers a simple solution: Engage with the task on the day it is assigned. Spend an hour outlining ideas or reviewing material. Even brief early engagement allows the mind to process information in the background. This turns procrastination into a structured advantage.

Procrastination is a great support for tasks that require creative problem-solving such as essays or complicated calculations. Allowing time for incubation is very important as the subconscious can now process what it already knows and try out new ways to solve the problem. The key is intentional delay while keeping clear deadlines.

Students can combine procrastination with exercises that promote divergent thinking. Thinking up alternatives, illustrating concept maps, or looking at a short strategy game can be great ways of developing flexibility. The research highlights that these exercises when combined with delayed engagement lead to better and more original outcomes than immediate effort.

Students must balance delay with discipline. Viewing procrastination as a tool rather than an obstacle allows a strategic approach to exams. Harvard-backed evidence shows that careful use of delay can boost creativity, improve problem-solving, and enhance performance. Memorisation is important, but insight and originality are also rewarded. Used wisely, procrastination can be a subtle advantage.
