What are the negative impacts of tribalism in a nation?

Tribalism can lead to social fragmentation, fostering division and conflict among different groups within a nation. It often results in discrimination, as individuals prioritize loyalty to their tribe over national unity, which can escalate tensions and violence. Additionally, tribalism can hinder economic development and governance by promoting nepotism and corruption, as resources and opportunities are allocated based on tribal affiliations rather than merit. Ultimately, this undermines social cohesion and national progress.
