Do we like Hank Green?
Our score: 8 out of 10. A long record of putting money and time behind other people, with a recent honesty stumble over AI and a botched knitting apology.
Hank Green is half of the Vlogbrothers, the video-blog duo he started with his brother John. From there he built a small education empire: Crash Course, SciShow and the company behind them, Complexly. He's also a novelist and podcaster, but the core of the job is making science and big ideas feel approachable.
The latest stoush is about trust, which is the thing his whole brand runs on. In July 2026 an AI-generated graphic in one of his videos had the sphere maths wrong, and he apologised. Then a line in an Ask Hank Anything episode, “I appreciate the pushback”, had fans convinced a chatbot wrote it. He says it was an ad-lib, deleted his post about it, and admitted he had used ChatGPT for research and was relying on it too heavily.
His response was a decent one. On Reddit he said he was mortified to have let people down, then paused his personal channel and the daily games SMUSH and 4x3. He also set a personal AI policy: no AI as a source or to write his scripts. Scientific American used the row to ask where AI belongs in science communication. Whether the disputed line was machine-written is still unresolved, so judge it on how he handled it.
There was also a knitting row in September 2025. A SciShow episode framed knitting as something physicists don't understand, and knitters were furious. Green posted a TikTok apology, saying he no longer runs SciShow day to day. Plenty of people said it didn't read as a proper apology, and SciShow later pulled the video. It's a stumble in how he handled criticism, not a pattern of meanness.
On the harm test, nothing nasty of his own turned up. In 2017, after Trump's travel ban, he pledged $5 to the ACLU for every hand-drawn message of support for immigrants, Muslims or refugees. That raised $11,065 for the ACLU, and a poster sale brought in about $71,750 more for refugee groups. The record on LGBTQ+ issues specifically is thin: I found no harmful words, but also no big campaign, so that's an honest gap.
He has also acted when accusations hit his own community. In 2014, when two musicians on the DFTBA Records label he co-founded were accused of sexual abuse, both were removed from it. Hank said a task force with Nerdfighters, including some abuse survivors, was under way and promised to fund a video series on abuse and consent. That's the kind of cost-bearing response the good-person test looks for.
