Humans Hard-wired for Geometry
hcg50a writes "An article on MSNBC reports that, according to a new study, even if you never learned the difference between a triangle, a rectangle and a trapezoid, and you never used a ruler, a compass or a map, you would still do well on some basic geometry tests, because we are hard-wired for geometry, rather than learning it from teachers or cultural influences."
Agreed.
Actually, they've done previous studies on these people to investigate whether they had innate arithmetic abilities by seeing if they could add large numbers, which they could only do approximately. As long as the numbers would fit on two hands, they were exact, but over that, not so much. It seems to me that the large number tests would just be comparing sizes of physical objects rather than actual math. (I don't think they gave them arabic numerals to add, but probably tick marks or other objects. It's just a guess: I don't know their exact methodology.)
What I find most revealing about this is their results on "handedness", which to me would help weed out pattern recognition versus spacial thinking (geometry). According to TFA, only 23% got it right... but 16% would get it right by guessing alone, so it's really not much better. Like the previous study, that seems to conflict with their conclusion rather than support it.
