It is worth noting, however, that of the animals demonstrating the highest EQ's (see associated table), many are primarily herbivorous, including apes, macaques, and proboscideans. The dietary factor, therefore, may be less significant than certain others, like gregariousness.

Another factor affecting relative brain size is sociality and flock size. For example, dogs (a social species) have a higher EQ than cats (a mostly solitary species). Animals with very large flock size and/or complex social systems consistently score high EQ, with dolphins and orcas having the highest EQ of all cetaceans, and humans, with their extremely large societies and complex social life, topping the list by a good margin.
