Thanks for pointing out these discrepancies, some so amusing I laughed out loud, especially the little convenient part about hiding the stuff that didn’t fit. This is my Very Scientific Observation. We have skulls. This is part of the exoskeleton. They grow until we are a certain age. Then, they’re solid. Our brains, which are a bunch of mush, keep growing. It is not possible, not physically possible to have a brain that is so large that it outgrows one’s skull. This means if you have a small-sized skull, as I do, you are doomed to have a small-sized brain. I was assured as a child that even though I was doomed by heredity to be mini, this had no bearing on intelligence nor had any bearing on anything else to do with what I thought about nor my brain’s capacity to do what it had to do. It seems that now, nearly six decades later, my mini-sized brain is functioning just fine. Actually no shrink ever pinpointed a specific “abnormality” in my brain. Perhaps its very existence was offensive to them! I have also concluded that these MRI-based arguments that we used to hear, as the authors here have pointed out, do not have much validity. The psych establishment only uses them to make intelligent-sounding arguments when they can’t think of anything else to say. The MRI has limited usefulness, except a neurologist might use it to pick up a massive blood clot if it’s obvious enough. It might show torn cartilage in a joint when an xray does not, but I am sure it tells us nothing about the way humans think. In fact, I got a good idea if anyone’s wondering. How about asking the person? Isn’t it cheaper?
