The Hawthorne effect, named after a famous series of studies conducted at the Hawthorne Works of the Western Electric Company in the 1920s and 1930s, is a fascinating phenomenon in industrial and organisational psychology. This effect describes the tendency of people to change their behaviour when they know they are being observed. Put simply, the mere fact that someone is paying attention to us can influence our behaviour.

The Hawthorne effect was originally observed in studies aimed at investigating the influence of working conditions on productivity. Surprisingly, it was found that both the improvement and the deterioration of working conditions led to increased productivity. The researchers concluded that it was not the specific changes to the working environment, but rather the workers' awareness that they were part of a study that influenced their performance.

Today, the Hawthorne effect is observed in many contexts. In schools, hospitals, offices and even in scientific studies, the knowledge that one's own behaviour is being observed or analysed can cause people to behave differently than they normally would. This knowledge of being observed can have both positive and negative effects, depending on the context and the expectations of those being observed.

The Hawthorne effect raises important questions regarding the implementation and interpretation of research results. In scientific studies, especially in social research, the possibility that the behaviour of participants is influenced by their awareness of their participation in a study must be taken into account. This can lead to biases that affect the validity of the results.

Understanding the Hawthorne effect also has practical significance in the world of work. Leaders and managers can use these insights to improve the motivation and productivity of their teams. By creating an environment in which employees feel observed and valued, they can potentially increase performance and commitment.

The Hawthorne effect is therefore a key element in understanding human behaviour. It shows us how complex and multi-layered the motivational and behavioural dynamics in groups and organisations can be and emphasises the importance of the human component in all types of work and research environments.

In summary, the Hawthorne effect is a fascinating example of how the mere perception of observation can influence our behaviour. It underlines the need to understand and consider human behaviour in context, both in research and in practice.
