    A quote from the Justo Gallego thread:

    I have a feeling that head size is not a sole indicator of intelligence, its the proportion of head to body as well as head size. For example (just for an example, this might not be scientifically correct) a body that is 5'5" (165cm) tall and 56 kilograms (123 pounds) will need a brain of 1000cc to possess an IQ of 150. A body that is 6'2" (188cm) and 98 kilograms (216 pounds) will need a brain of 2000cc to possess the same IQ.

    I think I have said this before: do not just read the face and the head, but also the body.

    I am a 5'10" (178cm) and 65 kilograms (143 pounds) Asian guy. Every day, I see throngs of white and Pacific Islander guys who are bigger and taller than me, and probably have bigger heads than me. However, they are not as smart. And there are people who are smaller than me who can have a conversation with me about complex topics.

    The next time you try to read someone, you might want to take into account his/her body size.

    Yes, encephalization is important. However, a smaller person will actually need a larger brain relative to their body size than a larger person will to have the same intelligence (ceteris paribus, of course), just as a mouse is not as smart or smarter than a human, despite both animals having very similar brain weight to body weight ratios.

    Encephalization quotient - Wikipedia, the free encyclopedia | https://en.wikipedia.org/wiki/Encephalization_quotient

    The 216 lb person with a 2000 cc brain would be expected to be smarter than the 123 lb person with a 1000 cc brain, because not only does the heavier person have a bigger brain relative to their body weight, but because they are a larger animal, they also don't need the same brain:body ratio as the smaller person to have the same encephalization quotient.

    It might be more useful to subtract a penalty based on body size from the head size? The reason for this effect is that larger bodies require more motor neurons, which don't contribute to intelligence. The neurons that do contribute to intelligence will still do so in proportion to size.

    Don't forget to read the voice as well, if possible. Giants go Boom.

    That is true. However,Tall heigth tend to be associated with gracility and leptomorphism. So it is questionable if "taller" really means the same as "larger".
