The second need in SDT is relatedness, which refers to the human need to feel understood and supported by others. We are social creatures who thrive on meaningful connections, whether we're introverted or extroverted.

Consider an individual who has emigrated to a new country. Initially, they may feel isolated and stressed about fitting into a new culture. However, by joining community events, language-learning clubs, or even attending a local yoga studio, they can gradually build relationships that make them feel supported and understood. These connections help fulfill their need for relatedness, providing them with a sense of belonging in a new environment.

In design, fostering relatedness means understanding and supporting users throughout their journey. An online platform that encourages collaboration or shared interests can create a sense of community. User interviews and diary studies can reveal insights that designers can use to build products that resonate with the need for relatedness.
