Why do we procrastinate?

Hello!

The start of a new year often inspires people to ditch unhelpful habits. Yet procrastination remains one of the toughest behaviors to change.

Why We Put Things Off

Whether the task is finishing a report, replying to an email, or going for a run, some activities feel overwhelming. The simplest escape is to delay them indefinitely. But what drives this habit, and can we reduce it?

“At its heart, procrastination is about avoidance,” Fuschia Sirois, a professor of psychology at Durham University in the U.K., told Live Science. The discomfort usually stems not from the task itself but from the negative emotions it triggers, she explained.

Beginning a college essay, for instance, can stir self-doubt. A vague prompt may spark fears of failure or criticism, prompting the urge to postpone the work.

Procrastination Is More Than Simple Delay

Procrastination is a voluntary and unnecessary form of delay. It is not caused by competing priorities or sudden emergencies. People usually recognize that the task matters to themselves or others, yet they still postpone it, knowing the potential negative consequences.

What Brain Research Shows

Chronic procrastinators often struggle to regulate their emotions. In a 2021 brain-imaging study, Sirois and colleagues found that students with greater gray-matter volume in the left dorsolateral prefrontal cortex—an area linked to self-control—were less likely to procrastinate. Stronger connections between this region and frontal areas helped participants manage negative feelings, focus on long-term rewards, and persist with tasks. Weaker connections correlated with higher procrastination rates.

Difficulties with emotion regulation also help explain why people with ADHD tend to procrastinate more frequently.

A 2018 study revealed that the amygdala—the brain’s threat-detection center—is often larger and more reactive in chronic procrastinators. Even minor triggers, such as choosing the right words for an email, can feel threatening. When the anticipated discomfort outweighs perceived consequences, avoidance wins.

The fewer neural connections that exist between the amygdala and the dorsal anterior cingulate cortex (which governs responses to perceived threats), the more likely a person is to procrastinate, the researchers noted.

Genes and Life Circumstances Both Play a Role

“Like any personality trait, there are some biological underpinnings,” Sirois said. Research links procrastination to impulsivity at the genetic level and suggests it can be inherited. However, she emphasized that biology does not determine destiny.

Environmental factors are equally influential. Even people who rarely procrastinate may start doing so when prolonged stress depletes their coping resources—for example, after the loss of a loved one.

“Procrastination becomes a quick, easy and ‘dirty’ way of coping with something, albeit in an avoidant way, when your coping resources are maxed out,” Sirois said. Ironically, putting tasks off often increases stress, creating a cycle that can harm mental health, academic performance, and finances.

Practical Ways to Break the Habit

Evidence shows that improving emotion regulation can significantly reduce procrastination. Sirois advises pausing when a task feels daunting: identify the emotions it evokes and examine why you want to avoid them. Clarifying instructions, breaking the work into smaller steps, finding personal meaning in the task, and rewarding progress can all help.

If your goal this year is to stop procrastinating, start with self-compassion. “Forgiveness for your procrastination is very effective in reducing subsequent procrastination,” Sirois said.
