Ethnic diversity poses a threat to global peace, progress, and security. Nigeria serves as a prime example of this issue, as the nation grapples with internal turmoil stemming from ethnic conflicts within the socio-political landscape. The act of aligning ourselves with our ethnic groups has fueled animosity towards other ethnicities and has led us to become mentally inflexible, causing us to view the world solely through the lens of our ethnic identity. Put simply, we struggle to make sense of anything beyond our ethnic affiliations. This study delves into the challenges presented by ethnic diversity through the lens of metaphysical principles and theories from 4E Cognitive Science, utilizing a metaphysicocognitive analysis approach. It posits that the process of aligning our worldview with our identity and relationships within our environment is an essential aspect of our existence in a shared world. Without this alignment, navigating the world becomes an insurmountable task. However, our cognitive adaptability plays a crucial role in determining whether our worldview alignment enables us to interact in a manner that promotes mutual growth and self-actualization. As cognitive beings, we are presented with a singular option to address the issues arising from ethnic diversity. This solution does not involve advocating for a form of homogeneity that favors one ethnic group over others. Instead, the focus should be on the cognitive mechanisms that govern our interactions within the world. This process must be intentional rather than incidental, emphasizing the importance of conscious effort in shaping our relationships with others.
