Hawthorne Effect

What Is the Hawthorne Effect?

The Hawthorne effect is a phenomenon in human behavior where individuals alter their actions or behaviors when they are aware of being observed or studied in an experimental setting.

This effect suggests that people tend to improve their productivity or behavior simply because they are aware of being studied or monitored.

In a workplace setting, if employees know they are being observed for a productivity study, they may work harder or be more diligent in their tasks, regardless of any specific changes in their working conditions.

Key points about the Hawthorne effect:

Origin: The term stems from experiments conducted at the Western Electric Hawthorne Works in Chicago in the late 1920s and early 1930s. The studies were initially focused on the relationship between lighting levels and productivity, but the observed changes in behavior could not be solely attributed to the lighting conditions.

Behavior Modification: Participants in the study altered their behavior because they were aware of being observed, which led to an increase in performance or changes in behavior.

Widespread Application: The Hawthorne effect has been noted in various fields beyond the initial workplace studies, including psychology, sociology, and user research, among others.

Significance: It highlights the influence of awareness and observation on human behavior, which is crucial to consider in experimental design and interpretation of results.

Hawthorne effect in interviews:

When individuals are aware of being watched, they tend to adjust their behavior, a phenomenon known as the Hawthorne Effect or observer bias.

In the context of interviews, this effect manifests when interviewees modify their responses to either impress the interviewer or present themselves in a more favorable light. This can lead to a distortion of the information provided, as the interviewee's responses may not accurately reflect their true thoughts or experiences.

Strategies like establishing a connection, assigning tasks that feel natural, and dedicating more time with participants can help alleviate this effect.

Does the Hawthorne Effect Influence Workplace Productivity:

The Hawthorne Effect can lead to increased productivity as employees may strive to perform better when they know they are being observed. This effect has implications for various aspects of workplace management and research.

When employees feel their actions are being monitored or they are part of an experiment (as in the original study), they tend to enhance their productivity. However, this effect is temporary because once the novelty or awareness of observation fades, productivity may return to its baseline. Acknowledging employees and making them feel heard can substantially boost their productivity.

Can the Hawthorne effect have negative consequences?

While typically seen as a positive influence on productivity and performance, it can also lead to negative outcomes, including increased stress and anxiety due to continuous surveillance and observation in the workplace, reduced authenticity, inhibition of creativity and risk-taking, employees may also develop resentment towards constant surveillance, and their overall long-term productivity may lead to burnout.

How can organizations leverage the Hawthorne effect?

Organizations can utilize the Hawthorne Effect by implementing performance assessments, setting clear expectations, and creating a positive work environment. However, it's important to recognize that this effect may be temporary, and sustained improvements require ongoing efforts.


In summary, understanding this phenomenon can provide valuable insights for employers and managers seeking to enhance workplace productivity and performance.

However, it's crucial to recognize that the Hawthorne Effect is just one of many factors that contribute to employee behavior, and a holistic approach to management is necessary for sustained positive outcomes.
