Reasoning & Evidence21 Jul 2026
The claim that "human beings naturally form groups and identify with them" is a broad assertion about human nature that is strongly supported by a substantial body of research in evolutionary psychology, anthropology, and related social sciences.
**Key evidence:**
1. **"Tribalism Is Human Nature"** — A 2019 article in *Perspectives on Psychological Science* (a peer-reviewed journal) explicitly states: "Selective pressures have sculpted human minds to be tribal, and group loyalty and concomitant cognitive biases likely exist in all groups." The authors conclude: "Tribal bias is a natural and nearly ineradicable feature of human cognition."
2. **The Tribal Instinct Hypothesis** — Mark van Vugt and colleagues argue, with extensive evidence, that "the social science literature abounds with examples of people's tendency to categorize others on the basis of group membership and to preferentially help ingroup members over outgroup members." They trace this to evolved psychological adaptations for group living.
3. **Evolution and the psychology of intergroup conflict** — A 2012 paper in *Philosophical Transactions of the Royal Society B* (PubMed Central) documents that "ingroup–outgroup biases have been documented widely among both Western and non-Western populations" and even "emerge when such group divisions are based on a random criterion." Group living "afforded benefits such as resource pooling, division of labour, cooperative parenting, protection from predators and territorial defence," creating selection pressure for sociality and group identification.
4. **Group formation research** — A 2023 article in *Perspectives on Psychological Science* on group formation and the evolution of human social organization confirms that humans naturally form groups through reciprocity, reputation, and shared norms, and that "individuals gravitate towards us-versus-them thinking."
The claim is a well-established finding in the scientific literature. Humans are an ultra-social species with evolved psychological mechanisms for group formation and group identification. This is not a controversial claim in the relevant sciences; it is supported by cross-cultural evidence, experimental studies, and evolutionary theory. No important qualification is missing from the core assertion.

From article
Yes. All this ‘Imagine there are no countries’, the idea that we all be the same, always struck me as bizarre. You know, we should be rather proud of who we are and what our history is. You see, the reason, in the end, that the European project can’t work – just as communism could never work – is that, whether we like it or not, mankind is tribal. I admit to being tribal.
