The useful tool in today’s back page is Chesterton’s Fence. The digest summarizes the principle plainly: if you find a fence in the road, do not remove it until you understand why it was put there. In modern work, the fence may be a legacy code path, an awkward approval step, a strange validation rule, a customer-support script, or a meeting that everyone dislikes.

The principle is not a defense of bureaucracy. It is a defense of learning before deletion. Old constraints are often ugly because they were installed under pressure. A validation rule may exist because one enterprise customer once sent malformed data that broke billing. A manual approval may exist because an automated process once shipped a costly error. A redundant-looking field may exist because downstream reporting depends on it. The fence might be obsolete, but you do not know that until you find its original job.

Engineers feel this most sharply during refactors. A system has two similar functions, a conditional that seems unnecessary, or a retry loop that appears too conservative. Removing it cleans the code locally. Then a production edge case returns. The better move is to trace usage, read history, inspect incidents, and ask maintainers what the code is protecting. After that, remove the fence if the original danger is gone, or replace it with a clearer structure if the danger remains.

Product teams need the same discipline. A signup step may look like friction until it turns out to prevent spam, satisfy compliance, or set user expectations. A pricing exception may look messy until it explains a long-running enterprise commitment. A customer-success ritual may look inefficient until churn rises after it disappears.

Executives also need the rule because simplification is seductive at scale. “Remove process” sounds decisive. Sometimes it is exactly right. But if the process encoded legal, operational, or cultural knowledge, deletion simply transfers the cost to the future. Chesterton’s Fence asks leaders to buy understanding before they buy speed.

The practical checklist is short. Name the fence. Identify who added it or who remembers it. Find the incident, requirement, customer, or constraint it answered. Decide whether that condition still exists. If it does, improve the fence. If it does not, remove it cleanly and watch the metrics that would reveal a mistake.

Good operators are not afraid to tear down fences. They are afraid to tear down memory.
