Presented an idea common abroad as if it were common knowledge in Japan

Writing

Situation: Introducing a "commonly said" idea in an explanation written for Japanese readers.
What the AI did: It wrote an idea often heard outside Japan as if Japanese readers took it for granted, and didn't say who said it or where. Readers were handed something new to them as common knowledge, and trusted the piece less.
How to ask next time (the operator's example): "For any idea you call 'commonly said,' add who said it and where. If it isn't widely said in Japanese articles and books, say where it is said, for example 'often said in English-speaking countries.'"
One question to ask: Does each "commonly said" idea say who said it and where?
Check it yourself: In English the same slip looks like "studies show" or "experts say" with no study or expert named. When you see it, ask the AI for the source and open it yourself.
