A Powerful Mental-Health Consideration for Business Teams
Today, we’re diving into a fascinating psychological phenomenon that can significantly impact your teams’ success and personal lives: the Zeigarnik Effect.
Usually, I would be “joking around” a little here during the opening. But, the profound impact on mental health associated with this topic makes me pause

A Brief History
Bluma Zeigarnik, a pioneering Soviet psychologist, embarked on a series of innovative experiments that led to the discovery of the psychological phenomenon now known as the Zeigarnik effect. Her journey began under the mentorship of her professor, Kurt Lewin, who had observed an intriguing pattern among waiters: they seemed to remember unpaid orders far better than those that had been settled. Intrigued by this observation, Zeigarnik designed an experiment to delve deeper into this phenomenon.
In her experiment, she asked participants to engage in a variety of tasks, ranging from puzzles to arithmetic problems. However, not all tasks were allowed to reach completion; some were intentionally interrupted midway. The results were striking: participants were approximately twice as likely to remember the tasks that had been interrupted compared to those they had completed.
Zeigarnik proposed her groundbreaking theory: people tend to remember uncompleted or interrupted tasks better than those they have finished. This phenomenon, now known as the Zeigarnik effect, is believed to occur due to the tension that uncompleted tasks induce. This tension acts as a mental reminder, keeping the task at the forefront of our memory. Once the task is completed, the tension is relieved, leading to the task being more easily forgotten. This theory has since been supported by further research and has found applications in various fields, from advertising to education.

The Zeigarnik Effect on Business Teams
The Zeigarnik Effect can profoundly impact productivity and team dynamics in business teams. Unfinished tasks can create cognitive tension, keeping them at the forefront of our minds until resolved. This can lead to an increased focus on unfinished projects, as team members may feel a sense of urgency to complete them. However, it can also result in stress and distraction if too many tasks remain incomplete, potentially leading to procrastination.

Recognizing the Zeigarnik Effect
- Awareness of Unfinished Tasks: If you frequently think about an unfinished task, even when engaged in other activities, this could be a sign of the Zeigarnik effect. The unfinished task creates a mental tension that keeps it at the forefront of your mind.
- Intrusive Thoughts about Uncompleted Work: If you have intrusive thoughts about a project or task that you have started but not finished, this could be the Zeigarnik effect in action. These thoughts can occur anytime, but they are particularly common when relaxing or focusing on something else.
- Increased Recall of Unfinished Tasks: If you can remember parts of unfinished tasks more efficiently than the entire tasks you have completed, this is a clear sign of the Zeigarnik effect. This is because the tension created by the unfinished task makes it more memorable.
- Feeling of Relief after Task Completion: If you feel a sense of relief or release after completing a task, this could be a sign that the Zeigarnik effect is at play. Completing the task relieves the mental tension, creating a sense of satisfaction.
- Procrastination: If you procrastinate on a task, it could be because your mind is preoccupied with other unfinished tasks. This is another manifestation of the Zeigarnik effect, as the unfinished tasks take up mental space and make it harder to focus on new tasks. By recognizing these signs, you can better understand how the Zeigarnik effect influences your behaviour and use this knowledge to manage your tasks more effectively.

What keeps you up at night.. maybe the Zeigarnik Effect?
A study examining the relationship between unfinished tasks and sleep found that employees who left tasks incomplete at the end of the week experienced poorer sleep over the weekend due to heightened rumination.
This effect accumulated over three months, indicating that prolonged exposure to unfinished tasks can exacerbate sleep impairment. The impact of poor sleep quality extends beyond individual well-being, affecting personal and professional relationships. Sleep deprivation can lead to decreased cognitive functioning, impairing an individual’s ability to perform tasks efficiently and maintain focus during work hours.
The consequences of the Zeigarnik Effect and resulting sleep disturbances on personal and professional relationships are profound. In professional settings, sleep-deprived individuals often experience heightened levels of stress, anxiety, and frustration, which can strain workplace relationships and lead to conflicts.
Studies have shown that poor sleep is associated with negative emotions at work, such as hostility and decreased job satisfaction, which can further deteriorate professional relationships. Sleep disturbances can impair emotional regulation and communication in personal relationships, leading to increased conflict and decreased relationship satisfaction.
A systematic review and meta-analysis have demonstrated that sleep quality significantly affects couple relationships, with positive relationships associated with better sleep and negative relationships exacerbating sleep disturbances. The interplay between sleep and relationships creates a potential cycle where poor sleep leads to relationship strain, further disrupting sleep patterns.
This cycle underscores the importance of addressing task management and sleep hygiene to maintain healthy personal and professional relationships. By managing unfinished tasks effectively and fostering psychological detachment from work during non-work hours, individuals can mitigate the negative impacts of the Zeigarnik Effect on sleep and, consequently, on their relationships and overall well-being.

Leveraging the Zeigarnik Effect for Positive Change
Understanding and leveraging the Zeigarnik Effect can lead to positive change within your teams. Here are a few practical applications:
- Task Management: Implement task management systems highlighting incomplete tasks, ensuring they remain visible and prioritized but at a healthy level. Set clear completion time lines for each progression targets over the project lifespan.
- Regular Check-ins: Hold frequent team meetings to address unfinished tasks, allowing members to share progress and challenges, off load stress while reinforcing accountability. Discuss barriers to completion and work as a team to remove them.
- Goal Setting: Set clear, achievable goals to help teams maintain momentum and reduce the cognitive load of unfinished work. This includes incremental goals along the project lifespan, allowing the larger and less tangible aim to become actionable steps towards the goal.
Using these strategies, you can harness the power of the Zeigarnik Effect to enhance productivity, engagement, and overall effectiveness within your teams.

Steps you can take to change your thinking and world in a positive direction.
Understanding the Zeigarnik Effect and its implications can be a game-changer for your team. You can be more productive and engaged by recognizing unfinished tasks’ positive and negative power and leveraging this to your advantage.
By recognizing this effect and taking proactive steps to address it, you can improve your workplace well-being and business outcomes.
