Perhaps. Separating out the home factor of homeschooling to get some useful truth seems quite impossible.
Can you say more about this? Or can you talk about your reasoning that makes 'home factor' the dominant factor?
Home schooling tends to just reinforce what is already true about the home environment, so there doesn't seem to be any new variable their. Of course, we could argue that schools can have adverse effects and that you are avoiding those by homeschooling, but since home life is so dominant, you'd expect kids to just regurjitate what they've learned at home anyways, at least until middle or high school where teenagers begin to break free.
