A false report rides post.

Understand the thought

Meaning in plain English

A false report can travel quickly as people repeat it. Speed or widespread repetition does not establish accuracy, so check the basis of a claim before passing it on.

What the words are saying

Rides post gives the report the image of rapid travel. The proverb draws attention to how an inaccurate account may reach people before its basis has been examined. It is a warning about repetition, not a measured rule that false information always moves faster than true information. A claim can become familiar through many copies of the same unsupported statement rather than through independent confirmation. The practical question is where it came from and what evidence supports it. When the account is uncertain, identify that uncertainty or wait for clarification instead of adding another confident version to the circulation.

Everyday example

A group member checks a rumour that an event has been cancelled with the organiser before forwarding it to everyone planning to attend.

When to use it

Use it when a rapidly circulating report has not been adequately checked.

Agent-assisted editorial interpretation. This explains the words; it does not by itself verify their author or earliest origin.
