Which theory suggests that gender is primarily shaped by social interactions and cultural norms rather than biological factors?

The theory that suggests gender is primarily shaped by social interactions and cultural norms is called social constructionism. This theory argues that our understanding of what it means to be male or female is not just about biology but is heavily influenced by the society we live in. For example, in some cultures, boys may be encouraged to play with trucks and be tough, while girls might be given dolls and taught to be nurturing. These expectations come from social norms and interactions, showing how gender roles are learned rather than innate. Therefore, social constructionism highlights that our identities are formed through our experiences and the messages we receive from others.
