"From this information, can we speculate that whales, with the largest total brain size, are therefore the most intelligent species? Let us look at a study reported by Kuhlenbeck (1973) with regards to intelligence and brain size. Studies of brains of "outstanding" or "genius" human individuals have been interpreted to show some statistical correlation between high brain weight and intellectual capacity. However, in individual cases, a person with a low brain weight around 1017g was highly gifted while another with a brain of 1800g was extremely mentally handicapped. In addition, one of the highest recorded human brain weights, mentions Kuhlenbeck, is said to have reached 2850g and this person was reported to be "an epileptic affected with idiocy" (Kuhlenbeck, 1973, 732). How does this affect our use of absolute magnitude of brain size to correlate with intelligence? For another example, the average weight of a "typical" adult male is +- 1400 while an adult female brain weight averages at +- 1300. Does this mean that males are more intelligent, more advanced than female humans? If we correlated large brain size with increased intelligence, then we would have to assume this comparison, yet on a whole it has not been documented that males are any more intelligent than females. Thus, it seems that statistical correlation of brain weight and "superior intellectual ability" remains rather inconclusive. Therefore, perhaps we should find another method for comparing brain sizes and structures of various species."
