Chesterton's Fence
By Shivam Bhandari · Reviewed 31 October 2026 · How we write
what it means
Don't remove a rule, process, or ‘fence’ until you know why it was put there in the first place.
How Chesterton's Fence works
New managers and founders love cleaning up legacy processes. Many really are useless — but some exist because of a painful past failure that no one remembers.
Chesterton's fence asks for a small amount of investigation before removal. If you find the reason and it no longer applies, remove it with confidence.
where it comes from
From English writer G. K. Chesterton's 1929 book The Thing, where a reformer wants to clear away a fence across a road and a wiser one says: first find out why it was built.
Chesterton's Fence examples in business
Approval step
A new COO scraps a second sign-off on vendor payments as ‘bureaucracy’. Months later a duplicate-invoice fraud recurs — the exact reason it was introduced.
Packaging
A brand removes an ‘unnecessary’ inner carton to save cost and breakage claims jump in monsoon season.
Pricing rule
A sales head learns a minimum order rule exists because small orders were loss-making after delivery costs.
