“It is a well-known paradox that humans are certainly the most cognitively advanced species but nevertheless show a smaller average brain size, by weight or volume, than elephants and whales. One attempt at a resolution of this paradox invoked the encephalization quotient (EQ), a measure of brain mass normalized essentially by body mass (Jerison, 1973). Many researchers found EQ appealing because it served well to distinguish humans from other species, but this measure turns not to provide an acceptable rank order of other species (Deaner, Isler, Burkart, & van Schaik, 2007; MacLean et al., 2014); for example, monkeys are more encephalized than the undoubtedly intelligent great apes (Deaner, van Schaik, & Johnson, 2006). Furthermore, the notion of an EQ may not be applicable to individual differences within the human species, for both birds and mammals exhibit within-species brain-body scaling that is weaker and more variable than in other vertebrates (Tsuboi et al., 2018).”
What do you mean by “mainstream science” ? Is it the scientific consensus ? Is it science as the mainstream media see it ? Is it science as perceived by the majority of people ?
Fine. It’s just that brain size is supposed to matter in intelligence, but this proves that it might not be the case. Even though it is said that brain to body size makes a difference, crows are just too advanced. And mainstream science would be what the major players in science say it’s true + what the mainstream media says.
How so? This is mainstream science.

so the higher intelligence in humans is not produced by :
size of brain (1),
mass of brain (2),
EQ == (2) / body mass,
Could it be related to the surface area of the neocortex ?

I doubt it’s mainstream even though it was published on Science.
