But I can guarantee you that those differences are, like differences associated with skin color, far less than the differences between individuals in the same group.
I always chuckle when people trot that one out. Did you know it's equally true for the differences between dog breeds? Body size varies more within dog breeds than between them. Also intelligence. Somehow that doesn't stop dog breeds from being fairly different from each other. (Actually, somewhat more than human races from the genetic studies I've seen.)
As for the differences between guys and girls being taught not inborn...how many kids do you have? Parents get disabused of that sort of thinking pretty quickly.
- rkts 17y agoBody size varies more within dog breeds than between them I have never understood what this means. "Within-group" variation can be quantified as standard deviation (among other metrics). How do you measure "between-group" variation? Sample the group means and find the standard deviation? But that's obviously meaningless.
- thras 17y agoYes, it is fairly pointless. However, they do mean something exact. You quantify the "within-group" variation not with standard deviations, but by measuring all individuals in a group and finding the endpoints. So you find the tallest white person in the world and the shortest, and note that they differ in height by a number of feet. Then you measure the difference between the white height average and the Asian height average, and note that the difference is only a few centimeters. Wallah! Race doesn't matter. Most variation is within group. Like I said, I chuckle a bit.
