Joscha Bach

German-American AI researcher and cognitive scientist. In November 2025, the U.S. House Oversight Committee released a 2016 email chain between Bach and Epstein containing racist, sexist, and eugenicist content. In these emails, Bach asserted that Black children lag behind white children intellectually due to biological factors, that women 'tend to find abstract systems, conflicts and mechanisms intrinsically boring,' and that fascism is 'probably the most efficient and rationally stringent way of governance.' The financial relationship was deep: Epstein introduced Bach to Joi Ito at the MIT Media Lab in 2013, and Epstein made $300,000 in donations to support Bach's research. From 2013 to 2019, Epstein personally covered Bach's rent, flights, medical bills, and private school tuition for his children.

Bach published a Substack response in 2025 acknowledging the emails and told the Boston Globe he has since changed his views on race and IQ. The emails were covered by the Boston Globe, Byline Times, and Fast Company. Bach has held positions at MIT Media Lab, the Harvard Program for Evolutionary Dynamics, and various AI research labs.
