As someone else who was homeschooled except the last three grades, I also agree. Additionally, the effect is multiplied if the kid in question lives in a rural or semi-rural area rather than a suburb or city.

For the majority of my adult life I’ve been playing catchup. Even now, barreling towards 40, there’s aspects of social capabilities where I come up quite short relative to my peers.

If I’m ever to be a parent, I won’t homeschool. Depending the circumstances I might not send my kids to public school, but their schooling situation will at minimum involve social exposure comparable to that of public school.
