Michel Eyquem de Montaigne, 1533-92 is a middle age Humanist, that shared his values in many books. You can enjoy reading him!
We have experts who (should) predict the future, economically, medically, psychologically, and …. they know! They have tribunes in newspapers, in media, and assert, all day long things that are not proved, rumors, rarely compliments, …
Tribunals rely on these same experts who know, to ruin lifes, and protect scammers because the tone of their voices is so certain, that it must be true.
Nature doesn’t like vaccuum, and when Something is empty, it is rapidly filled with what exists. This is why what is unknown is believed, more than certain and proved. But we could just say that it is just an asumption, and tell our ignorance. On the contrary, as nobody can prove it, one asserts a possibiity as being the Truth. We could stay humble, but our human nature put some pride in us, so that we can not be wrong.
Banks, that lead the economy, rely on experts, who shares their common same beliefs in committees, whose forecasts are always wrong, but they continue just for personal reinssurance of the decision makers.
As a final conclusion, I would like that people looking for funds for their projects are more trusted, because they have a direct knowledge of what they do, compared to anonymous or famous experts, who will be wrong anyway. Spend time with these people, not with advisors who usually are just a protection to avoid to say no directly.
