Limitations of research

Some researchers question the number of dimensions of ethnic identity development. For example, some measures of ethnic identity development include measures of behaviors, such as eating ethnic food or participating in customs specific to an ethnic group. One argument is that while behaviors oftentimes express identity, and are typically correlated with identity, ethnic identity is an internal structure that can exist without behavior. It has been suggested one can be clear and confident about one's ethnicity, without wanting to maintain customs. Others have found evidence of a behavioral component of ethnic identity development, separate from cognition and affect, and pertaining to one's ethnic identity.
