These questions around what intelligence is and what it means have intrigued and inspired researchers at Harvard’s Project Zero for over 50 years, and our inquiry suggests that intelligence, far from being singular, innate and fixed, is in fact multifaceted and learnable. Rather than equating being smart with scoring the highest test scores, or being born with a fixed amount of ‘smartness’, we believe that being smart is having a profile of learnable intelligences that enables one to identify and solve problems, and to create products that are of value in contemporary society. In short, we propose that intelligence is multiple, dispositional and learnable.
