The 'Naive Belief' Effect: How Managers Unintentionally Overload Motivated Employees

Published March 25, 2026 · TrendNet Editorial

What You Need to Know

The 'Naive Belief' Phenomenon

A study published in the Journal of Applied Psychology found that managers tend to give more work to employees they perceive as intrinsically motivated. This phenomenon is based on the 'naive belief' that these employees will thrive under increased workload. The study surveyed 239 employees and their managers, and found that managers perceived employees with high intrinsic motivation as being more capable of handling additional work.

According to Dr. Adam Grant, a professor at the Wharton School of the University of Pennsylvania, 'managers often assume that employees who are passionate about their work will be more productive and efficient, and therefore can handle more work.' However, this assumption can be misleading. 'In reality, employees with high intrinsic motivation may be more susceptible to burnout and decreased motivation if they are overloaded with work,' Dr. Grant notes.

The Consequences of the 'Naive Belief' Effect

Research suggests that the 'naive belief' effect can have negative consequences for both employees and organizations. A study published in the Journal of Occupational and Organizational Psychology found that employees who were perceived as intrinsically motivated were more likely to experience burnout and decreased motivation when given additional work. This can lead to decreased productivity, increased turnover, and negative impacts on employee well-being.

Furthermore, the 'naive belief' effect can also perpetuate inequality in the workplace. A study published in the Journal of Applied Psychology found that managers were more likely to give additional work to employees they perceived as intrinsically motivated, regardless of their actual workload or capacity. This can lead to some employees being overworked and underappreciated, while others are underutilized.

Breaking the 'Naive Belief' Cycle

So how can managers break the 'naive belief' cycle and avoid unintentionally overloading motivated employees? Dr. Grant suggests that managers should focus on employee well-being and capacity, rather than just their motivation. 'Managers should be aware of the potential for burnout and decreased motivation, and take steps to prevent it,' he notes. This can include providing employees with regular feedback and support, setting realistic goals and expectations, and encouraging work-life balance.

Additionally, managers can use tools such as workload management software to track employee workload and capacity. For example, workload management software can help managers identify employees who are at risk of burnout and take steps to prevent it.

What to Watch Next

The 'naive belief' effect is just one example of how unconscious biases can impact the workplace. As we move forward, it's likely that we'll see more research on the topic of workplace biases and their impact on employee well-being and productivity. Some potential areas to watch include the impact of biases on employee promotion and advancement, the role of AI in perpetuating biases, and the effectiveness of diversity and inclusion initiatives in addressing biases.
