They don't. Or not nearly enough. Otherwise you wouldn't have automated racial profiling, en masse face recognition, credit and social scoring etc.
And it's going to get worse. Because AI is infallible, right? Right?!
That's why, among other thing, EU AI regulation has the following:
- Foundation models have to be thoroughly documented, and developers of these modes have to disclose what data they were trained on
- AI cannot be used in high-risk applications (e.g. social scoring etc.)
- When AI is used, its decisions must be explicable in human terms. No "AI said so, so it's true". Also, if you interact with an AI system it must be clearly labeled as such
