I just met a young homeschooled man yesterday. He was an Arab from Jerusalem. He helped me unlock my car and make a new key after I left it at the airport and lost the key. He looked to be early 20s, and was incredibly professional, polite, and polished. It startled me given my usual interactions with Gen Z people (no eye contact, discomfort speaking with an older adult, rudeness). That and a few other interactions (obviously small N) made me think there's not much to the idea that homeschooled kids "lack social skills." I think an equally likely theory is that kids who are homeschooled in a community setting have better social skills when talking to adults and elders.
