How the facts are checked

No source, no line

Every factual line of a script names its source. The production pipeline refuses to make the final version of a video while a single claim is unsourced or the script has not been approved.

Where the sources come from

• How the city works (ground, water, transport) is checked against engineering studies, government agencies and peer-reviewed papers, with the years of every figure shown on screen.
• Rules, prices and visas are checked against the authority that sets them and carry “as of [month year]”, because they change.
• Food and history are checked against official sources (such as UNESCO listings) and well-referenced histories; food science is textbook knowledge, said as such.
• Places on the map come from OpenStreetMap. Episodes about something citywide (the heat, a dish, a rule) sit at a representative point, and the episode says so.

Two gates

A person reads the script, the sources and every number on screen before a video is finished, and watches the finished video before it is published. Each approval is tied to a fingerprint of exactly what was approved, so any later change needs a new approval.

Say what the source says

When a source hedges, so do we. Drawings that exaggerate a scale say so on screen (“illustration · vertical scale exaggerated”).

Corrections

Found a mistake? Tell us: [email protected]. Corrections are marked on the episode’s page under “Corrected” with the date, and the video is remade when needed.

Voice, music and pictures

The narrator’s voice is AI-generated. A person writes and checks the scripts and sources. The animation is drawn for the channel and every sound and bar of music is made for it. The map of Bangkok is drawn from OpenStreetMap data, © OpenStreetMap contributors (ODbL).
