Despite recent half-baked claims to the contrary, it is widely accepted that dolphins are very smart. This is largely based on an estimation of brain power derived from the brain size to body size ratio or “encephalisation quotient”. Dolphins have an EQ that’s second only to humans. Although that’s certainly a compelling argument for brainpower, scientists have begun to adopt the view that behavior is an even more accurate measure of intelligence within a species.
And with that in mind, it seems like new, exciting dolphin behavioral discoveries are cropping up every few months lately that support an even greater estimation of dolphin intelligence. Nova Spicack’s interesting article “Dolphins are Smarter Than We Think” points to recent discoveries where dolphins have a sense of the future and are able to delay gratification.
