The results of a first of its kind research study have revealed that dolphins have developed a number of similar personality traits* to humans, despite having evolved in vastly different environments! The study examined 134 male and female bottlenose dolphins from eight facilities across the world, with each dolphin’s personality being assessed by staff at the facilities. Among the shared personality traits between humans and dolphins: curiosity and sociability.
*Researchers used the most widely accepted model of human personality which is defined by five traits, and are replicated everywhere in human personality, regardless of environment. These traits can be summarized as openness, conscientiousness, extraversion, agreeableness and neuroticism.
