reciprocity

Reciprocity operates as the foundational currency of every sustained relationship, whether human or otherwise, and it consistently demands that giving precede asking. Mutual exchanges — of trust, loyalty, respect, or even practical help — only hold when both sides contribute; any asymmetry turns the relationship into a double standard or, worse, a form of exploitation disguised as connection. The principle scales across contexts that initially seem unrelated: introducing yourself before requesting personal details, remaining faithful if you expect faithfulness, tolerating views you find strange, or trading valued resources to enlist help from another species. Strikingly, the clearest documented cases of transactional thinking in non-human animals, such as the dolphin offering a sea cucumber to a fisherman and returning with gifts, suggest reciprocity is not a cultural construct but a deep feature of how beings recognize and reward cooperation. Ultimately, reciprocity is less a negotiation tactic than a baseline test for whether a relationship is real at all.
