The lesson
The card every stall must hang
Every stall in Singapore hangs a card on the wall, and you have seen it 1,000 times. A cleanliness grade, given by inspectors, by law, right where every customer can read it. Mine has hung there for years. Let me tell you a secret about it. The card is not my honesty. My honesty is what I do at 5:30 in the morning, when the market is dark and nobody is watching. The card is what I can show you. And in a busy world, showing beats promising.
Believe, and be able to prove
Ethics is what you believe. Governance is what you can prove, and the proof is made of procedures. My morning checklist: fridge temperature, written down, twice a day. My stock rule: when in doubt, throw the whole batch out. My spot checks: the inspector arrives without an appointment, and I am glad. A check you can schedule is a check you can cheat. AI needs the same furniture. Before a system is let loose, somebody tests it, the way the inspector opens my fridge. Its ingredients are written down. Researchers call that a model card. Its risk decides how hard the inspection is. A system that recommends noodles is 1 thing. A system that decides who gets a loan is another. And for the decisions that touch a life, a human stays in charge, and the system advises. At my stall, that human is me, and I taste the dish before it leaves the wok.
Grades for machines
This is already happening, and you have walked past it. Singapore publishes a governance framework for AI. Companies run their systems through AI Verify, a national test kit, before launch. It checks fairness and safety, the way my stall is checked for grease. Europe went further and sorted AI by risk. It banned the uses it found unbearable, and it demanded heavy inspections for the high ones, like hiring and lending. Some sellers grumble, the way some stallkeepers grumble about inspectors. The good ones sleep better.
The clipboard is yours
Now you are the inspector, and the clipboard is yours. A company has hired an AI to shortlist job applicants. Walk it round my route. Look at the record: what did it learn from, and can you read the list? Open the history: who tested it, and what did they find? Find the human: when it rejects somebody, who reviews the letter before it goes out? And ask my favourite question: when it makes a mistake, and it will, what exactly happens next? If any answer is nobody, nothing, or we will know when it happens, you have found the dirty corner behind the fridge.
