Four elements are considered:
- The neurophysiological factor which is simply a physical characteristic in the conception of the brain. It is primarily a right hemisphere dominance resulting in a more pronounced global reasoning (not suited to the sequential formal education system) but also the presence of a nerve impulse traveling more quickly.
- Hereditary factor: It plays a very important role since it is now established that intelligence is mainly explained by genetic factors.
- Environment: A favorable cultural environment, it means a good academic support, which can help to achieve outstanding achievements by the constant supply of new knowledge.
- Will: An ambitious and determined personality can help positively.
