According to Kelly, people belong to the same cultural group because they:

The assertion that people belong to the same cultural group because they construe their experiences in the same way aligns closely with Kelly's Personal Construct Theory, which emphasizes the subjective interpretation of experiences. In this context, construing experiences involves how individuals perceive and make sense of the world around them, influenced by their personal constructs—mental frameworks that shape their understanding and reactions.

This shared method of interpretation can create common ground among individuals, leading them to form a cultural identity that reflects their collective understanding and responses to similar experiences. Thus, members of a cultural group often see and experience the world in ways that are consistent with one another, reinforcing their group identity.

While sharing similar values, having similar educational backgrounds, and living in the same geographic location can contribute to a sense of belonging to a cultural group, it is the way individuals interpret and assign meaning to their experiences that fundamentally unites them on a deeper psychological level. This aspect of construing experiences captures the essence of Kelly's theory, highlighting the importance of individual perception in defining cultural membership.
