“In other words, experts are often called in, not to provide factual information or dispassionate analysis for the purpose of decision-making by responsible officials, but to give political cover for decisions already made and based on other consideration entirely. The shifting of socially consequential decisions from systematic processes, involving millions of people making mutual accommodations- at their own costs and risks- to experts imposing a master plan on all would be problematic even if the experts were free to render their own best judgment. In situations where experts are simply part of the window dressing concealing arbitrary and even corrupt decisions by others, reliance on what “all the experts” say about a given issue is extremely risky. Even when the experts are untrammeled, what “all the experts” are most likely to agree on is the need for using expertise to deal with the problem.”
“Experts have their place and can be extremely valuable in those places, this no doubt being one reason for the old expression, “Experts should be on tap, not on top.”

“People on both sides of the ideological fault line may believe that those with the most knowledge should have the most weight in making decisions that impact society, but they have radically different conceptions of just where in society there is in fact the most knowledge. If knowledge is defined expansively, including such mundane knowledge whose presence or absence is consequential and often crucial, then individuals with Ph.D.’s are as grossly ignorant of most consequential things as other individuals are, since no one can be truly knowledgeable, at a level required for consequential decision-making for a whole society, except within a narrow band our of the vast spectrum of human concerns.”
“The ignorance, prejudices, and groupthink of an educated elite are still ignorance, prejudice and groupthink- and for those with one percent of the knowledge in a society to be guiding or controlling those with the other 99 percent is as perilous as it is absurd. The difference between special knowledge and mundane knowledge is not simply incidental or semantic. Its social implications are very consequential. For example, it is far easier to concentrate power than to concentrate knowledge. That is why so much social engineering backfires and why so many despots have led their countries into disasters.”
From Intellectuals and Society by Thomas Sowell

“The capacity to grasp and manipulate complex ideas is enough to define intellect but not enough to encompass intelligence, which involves combining with judgment and care in selecting relevant explanatory factors and in establishing empirical tests of any theory that emerges. Intelligence minus judgment equals intellect. Wisdom is the rarest quality of all- the ability to combine intellect, knowledge, experience, and judgment in a way to produce a coherent understanding. Wisdom is the fulfillment of the ancient admonition, “With all of your getting, get understanding.” Wisdom requires self-discipline and an understanding of the realities of the world, including the limitations of one’s own experience and of reason itself. The opposite of intellect is dullness or slowness, but the opposite of wisdom is foolishness, which is far more dangerous.”
“George Orwell said that some ideas are so foolish that only an intellectual could believe them, for no ordinary man could be such a fool.”
