[ruh-roh]

Is there a term for the phenomenon where a supremely powerful person can comment on some event that may happen, perhaps innocently, and the fact they said it makes it more likely to happen?

In many ways, the health of an economy is a state of mind and emotional. Bezos has millions of people following his every word; many worship him and believe he has the keys to success (could also say the same about Musk & Gates). A pessimistic statement like this, regardless of merit, can/will cause others to be pessimistic.

In a vacuum I would be very interested in Bezos's thoughts on this topic - he's clearly super-intelligent. But I don't think I could get past his powerful position and the many reasons why he may want to sway opinion.
