This explains much…

Was catching up with some reading from when I was away and came across this article from the Register which refers to the Dunning Kruger effect:

The Dunning-Kruger effect is an example of cognitive bias in which "people reach erroneous conclusions and make unfortunate choices but their incompetence robs them of the metacognitive ability to realize it". The unskilled therefore suffer from illusory superiority, rating their own ability as above average, much higher than actuality; by contrast the highly skilled underrate their abilities, suffering from illusory inferiority. This leads to a perverse result where less competent people will rate their own ability higher than relatively more competent people. It also explains why actual competence may weaken self-confidence because competent individuals falsely assume that others have an equivalent understanding.

So you end up with idiots in charge who’re too stupid to realise the limits of their abilities; and intelligent people -knowing that they are fallible- saying nothing in the hope that there is someone up there who knows what they are doing.

There isn’t and they don’t.
