“Ignorance more frequently begets confidence than does knowledge: it is those who know little, not those who know much, who so positively assert that this or that problem will never be solved by science.”
Along with those assertions (with no evidence) that this or that will not be solved, it is the assertion that I have a solutiuon for your complex problem that is simple and straightforward and usually involves NOT doing something that is being performed improperly, which I'll label as a dysfunction and ignore the search for the root cause.
Which bring the next quote for simple and simple-minded solutions to complex problems.
For every complex problem there is an answer that is clear, simple, and wrong. H. L. Mencken
