From the The Pilot, Michael Pakaluk, a professor of philosophy in Cambridge, Mass writes:
"Strikingly, homeschooled children do not show the “black/white” test-score gap that is the bane of public and private schools. Likewise, homeschooled children perform equally well regardless of gender."
He doesn't quote his sources, and I would normally guess that these could well be just so much HSLDA noise, were it not for the fact that this does seem to be the case on the ground here. OK, so we are creating another stereotype here, "HE kids don't stereotype and therefore don't suffer the consequences", but as stereotypes go, it is one of the more constructive ones!
Another thing he says:
"Homeschooled children socialize better. Yes, the truth is actually the opposite of the common criticism, that “homeschooled children do not socialize well.” Homeschooled children learn to deal easily with people of all ages -- babies, parents, friends of parents, and the elderly. They acquire a mature, “adult” mentality from an early age. (I know I’m in a homeschooling household when I sit down to talk with a friend and find that his teenage children actually want to sit with us and listen to our conversation!) In contrast, there is absolutely nothing less well-suited to good “socialization” than placing a child with hundreds of other children who are exactly the same in age. Remember that “homeschooling” has been the norm for nearly all of human history; compulsory education in common schools is a recent phenomenon, dating from about 1850."
which also seems about right in our experience. For example, in very recent history, home educated Ds has twice been chosen as the friend that a schooled child wanted at their birthday celebration. These school children preferred to spend their special time with one HE child, rather than any of all the others with whom they are forced to spend all their time in school. It is tempting to draw conclusions from this.
