Brian Cox: "The Biggest Threat I Really Do Think Is Still Human Stupidity"
Physicist Professor Brian Cox has spent his life explaining the universe, from the smallest particles inside atoms to black holes and distant galaxies. Yet when he is asked about the biggest danger facing humanity, he does not talk about anything out in space. He talks about us.
"But the biggest threat I really do think is still human stupidity, or however you want to put it," Cox told IFLScience in an interview published on July 9, 2018.
In the same conversation he named the outcome he worries about most: "I still think the most likely way we'll wipe ourselves out is nuclear war, either accidental or deliberate."
Cox is one of the most recognized scientists in Britain. He is a professor of particle physics at the University of Manchester. He has worked on the ATLAS experiment at CERN's Large Hadron Collider near Geneva, the giant particle accelerator whose experiments confirmed the Higgs boson in 2012. Outside the lab, millions know him as the presenter of BBC series such as "Wonders of the Solar System," "Wonders of the Universe," "Human Universe," and "The Planets." His path to science was unusual. In the 1990s he played keyboards in the pop band D:Ream, whose song "Things Can Only Get Better" reached number one in the UK.
The idea behind his 2018 comment is one Cox has repeated for years. In talks and interviews, he has argued that the dangers people tend to fear most, like asteroid strikes, are much less likely to end civilization than mistakes made by humans themselves. His point is that humanity now has the power to change the entire planet, through weapons and through what we do to the environment, and the outcome depends on whether we make decisions guided by evidence and reason. Prospect Magazine summarized his view by describing human stupidity as the most serious threat to our future.
His warning about nuclear war echoes concerns that scientists have raised since the 1940s. In 1947, the Bulletin of the Atomic Scientists created the Doomsday Clock, a symbol of how close its experts believe humanity is to destroying itself. Cox's mention of an "accidental" nuclear war reflects a real worry among researchers: that a technical error or a misunderstanding could start a conflict nobody intended.
A short version of his message has spread widely online as "My greatest fear for humanity is our own stupidity." We searched interviews, articles, and transcripts for that exact sentence and could not find it. The meaning is close to what he has said many times, but because quotes on this page must be accurate, the post uses his verified words from 2018.
Cox has also said many times that science gives him hope. In his view, the same curiosity and evidence that reveal the universe can help people make wiser choices about the future of the planet.
Do you think humanity is its own biggest threat? YES OR NO?
