--Wizard of Oz (The Wizard of Oz)
In a society that values credentials, critical thought and reason will be prone to decline. A person with a degree, license, certification, etc is liable to be believed even if what they say is flat out wrong. Essentially, people outsource their brains to so-called experts. By not thinking for themselves, those people are likely to be played.
Proposition: The higher that a society values credentialism, the more that people will be misled by those with credentials.
