What does 'usefulness' refer to in the context of psychological study?

In the context of psychological study, 'usefulness' primarily refers to the contribution to human welfare. This means that research should ideally have a positive impact on individuals or communities, addressing issues such as mental health, social behavior, or educational practices. When psychological findings contribute to improving lives, enhancing well-being, or fostering social change, they demonstrate their usefulness in a practical and meaningful way.

While other aspects, such as practical application or entertainment value, can certainly play a role in how research is perceived, the core of 'usefulness' in psychology emphasizes the significance of research outcomes in advancing human welfare and solving real-world problems. Thus, the focus on contributions to human welfare captures the essence of how psychological studies can have far-reaching, beneficial implications for society.
