Overton window

 Ah! You’re asking about the Overton Window — specifically in the context of the UK, or more generally? I’ll explain carefully.





What is the Overton Window?



The Overton Window is a political theory describing the range of ideas that are considered acceptable or mainstream in public discourse at a given time.


  • Named after Joseph P. Overton (1960–2003), an American policy analyst
  • He suggested that any idea can be proposed, but only some are politically “viable” — the rest are seen as radical, unthinkable, or unacceptable.




Key points:



  1. Acceptable ideas = ideas politicians can publicly support without losing credibility.
  2. Radical ideas = too extreme for public support today.
  3. Window shifts = the range of acceptable ideas can change over time due to:
    • Media framing
    • Activism or advocacy
    • Cultural shifts
    • Crises or events



Example (UK context):

Topic

1990s Acceptable

Now Acceptable

Previously Radical

Cannabis legalisation

Mostly illegal / taboo

Limited medical use debated

Full legalisation

Same-sex marriage

Controversial

Legal (2014)

Criminalised decades ago

Universal basic income

Fringe policy

Debated in think-tanks

Radical in politics

So the Overton Window shows what is politically possible in a society without shocking the public.




If you want, I can make a UK-specific Overton Window map showing what’s mainstream, debated, and radical on hot issues today (2026).


Do you want me to do that?
