If you’re a “morning person,” you’re more likely to undermine your performance on a stressful task early in the day, research suggests. The same goes for “night owls” and performance in the evening.

The seemingly counterintuitive results, recently reported in the Journal of Experimental Social Psychology, are based on an investigation into the connection between people’s circadian rhythm and risk of “self-handicapping,” or self-sabotage. But rather than trying to protect against possible failure more at “off-peak” times, the study found, people actually engage in this behavior more at their peak times.

“Only people who had their peak cognitive resources were able to engage in self-handicapping.”

Psychologists define self-handicapping as when an individual seeks to protect their ego against potential failure in advance by creating circumstances—real or imagined—that harm their ability to carry out a stressful task. A classic example is failing to study or staying out too late the night before an important test or job interview.

The behavior also extends to mere claims of debilitating circumstances, such as imagined illness, fatigue, or stress. Other studies have linked self-handicapping to other self-destructive behaviors, such as aggression, overeating, and drug or alcohol addiction.

The study also found that people chronically prone to making excuses reported the same stress levels at “off-peak” hours as peers who do not engage in this behavior. Only at peak hours did these individuals report higher levels of stress as an excuse for poor performance.

Self-sabotage takes real effort

“What this study tells us is that self-handicapping requires thought and planning,” says Ed Hirt, professor in the Indiana University Bloomington department of psychological and brain sciences and an author of the study. “People who are feeling uncertain about themselves and start to fear that they might fail are more likely to identify potential excuses and self-handicap when they’re at their peak than when they’re not.”

“When an individual’s positive self-views are threatened, they may lash out against the source of the threat, compare themselves to others worse off than themselves, or engage in self-destructive actions, such as substance abuse,” adds Julie Eyink, a graduate student in Hirt’s lab and lead author of the study. “Unfortunately, it’s not uncommon to get caught in a negative spiral, in which self-handicapping leads to lower self-esteem and higher failure beliefs, which prompt more self-handicapping.”

Stressful testing

To conduct the study, the researchers administered intelligence tests to 237 students (98 men and 139 women), half of whom were told that stress had been found to affect performance on the test and half of whom were told that stress should not affect the result. The tests were given at either 8 am or 8 pm.

The volunteers had been previously categorized as “night people” or “morning people” based upon a survey shown to accurately predict circadian rhythm. Study participants were also assessed before the exam for their tendency to self-sabotage through questions about their stress levels.

The tests were given two weeks after the morning or night preference assessments, and participants were unaware that circadian rhythm would be a factor in the study. The individuals who administered the tests were unaware who had been labeled “morning people” or “night owls.”

The results were that people who scored higher in terms of risk for self-sabotage reported greater stress levels at hours of peak performance.

A high or low tendency to self-sabotage did not make a difference at off-peak hours, however. Both groups reported the same stress levels at these times.

“The results seem counterintuitive, but what they really show is clear evidence that self-handicapping is a resource-demanding strategy,” Eyink says. “Only people who had their peak cognitive resources were able to engage in self-handicapping.”

How to avoid sabotaging yourself

Based solely on the study, she says, people who want to avoid self-sabotage might conclude that they should engage in stressful tasks at off-peak times. But she also warns that such a strategy would require carrying out tasks at a time when a person lacks all the cognitive tools required to achieve top performance.

“Ultimately,” she says, “I would advise that working to avoid self-handicapping—through actions such as healthful practices, seeking help, or counseling—is the best strategy.”
