    Foire aux questions

    Biological bribery is a term used by evolutionary anthropologist Anna Machin to describe how evolution uses neurochemical euphoria to motivate humans. According to this theory, the intense feelings associated with love act as a reward or 'bribe' to ensure individuals engage in and maintain relationships. These bonds are considered critical to human survival, providing the necessary incentive to overcome the exhaustion and effort often required when dealing with other people.

    Neurochemistry plays a vital role in human cooperation by drugging the brain with feelings of euphoria that make social bonds feel rewarding. Evolutionary anthropology suggests that humans are highly cooperative because they have to be for survival, rather than simply wanting to be. Without this chemical hit, the challenges of social interaction might lead individuals to choose a solitary existence, which would be detrimental to the species' long-term survival and success.

    From the perspective of evolutionary anthropology, love evolved as a pragmatic tool for survival rather than just a poetic mystery. Experts like Anna Machin argue that the evolution of love was necessary to reward humans for engaging in critical survival relationships. By creating a high that results in lost sleep and reduced hunger, evolution ensures that humans remain focused on building the cooperative bonds required to thrive in a challenging environment.
