Bret Weinstein
Bret Weinstein is the evolutionary biologist, podcast host, and ideological lightning rod who turned a campus protest into a national debate, and never stopped being controversial.
Who Is Bret Weinstein?
Bret Weinstein (born 21 February 1969) is an American evolutionary biologist best known for hosting the DarkHorse Podcast with his wife, fellow biologist Heather Heying. He holds a PhD in evolutionary biology and spent years as a professor at The Evergreen State College in Olympia, Washington, before a very public and acrimonious departure.
He is also the brother of mathematician and podcaster Eric Weinstein, and the two are often grouped together as central figures in what became known as the “Intellectual Dark Web”, a loose coalition of thinkers who positioned themselves outside mainstream media and institutional orthodoxy.
His national profile exploded in 2017 when he publicly objected to Evergreen State’s “Day of Absence” event, which asked white students and faculty to leave campus for a day. The ensuing campus confrontation, protests, and threats became a flashpoint in the broader culture war over free speech on college campuses. He eventually resigned and received a $250,000 settlement from the college. He co-authored the bestseller A Hunter-Gatherer’s Guide to the 21st Century (2021) with Heather Heying.
In recent years Weinstein has leaned into heterodox politics and contested health commentary. He promoted ivermectin as a COVID-19 treatment and expressed skepticism about mRNA vaccines, positions rejected by the scientific consensus and criticized by prominent experts including cardiologist Eric Topol, who identified him as a leading source of COVID misinformation. In 2024 he suggested some AIDS cases are not caused by HIV, a claim that directly contradicts established science: the causal link between HIV and AIDS is one of the most thoroughly documented facts in modern medicine. He backed RFK Jr. and then Donald Trump in 2024, and remains a go-to guest for major podcasts, including a late-2025 appearance on the Joe Rogan Experience.
