Thomas “Tom” Chivers began writing for the Telegraph in 2007. Chivers was science editor at UnHerd from 2018 to 2022, then became the science writer at the i newspaper.

Chivers has written for the Times, the Telegraph, the Observer, the Guardian,, New Scientist, CNN, Wired, Smithsonian Air & Space, BuzzFeed UK.

Chivers is author of The Rationalist’s Guide to the Galaxy (2019), How to Read Numbers (2021), and Everything is Predictable (2024).

Anti-trans activism

Setting aside some questionable pieces on “Thai transvestites” and what-not, Chivers’ first salvo in anti-transgender activism was a 2014 piece using Laverne Cox to assert that trans women are not women. Chivers then characterizes biologists who use value-neutral terms and conceptualizations as engaging in “science denial.” Chivers defends the term “biological sex ” and supports anti-transgender reparative therapy.

Chivers is situated within the right-wing media landscape in the UK:

The UK has an increasing number of small but influential online-only media, in addition to the websites, apps and podcasts of many of the titles listed above. On the political right, sites like Conservative Home, Spiked, UnHerd, CapX, Reaction and The Spectator’s Coffee House blog are sources of right-wing opinion and debate but play relatively little role in breaking news stories.
