Conventional wisdom
Encyclopedia
Conventional wisdom is a term used to describe ideas or explanations that are generally accepted as true by the public or by experts in a field. Such ideas or explanations, though widely held, are unexamined. Unqualified societal discourse preserves the status quo
Status quo
Statu quo, a commonly used form of the original Latin "statu quo" – literally "the state in which" – is a Latin term meaning the current or existing state of affairs. To maintain the status quo is to keep the things the way they presently are...

. It codifies existing social norms, which promote some objective social good. It can also eschew an empirical outlook which is needed in many pursuits. The potential damage of radical change can be minimized. Rigor can be brought back and conflation avoided in any worthwhile subject.

Origin of the term

The term is often credited to the economist John Kenneth Galbraith

:


It will be convenient to have a name for the ideas which are esteemed at any time for their acceptability, and it should be a term that emphasizes this predictability. I shall refer to these ideas henceforth as the conventional wisdom.


The term in actuality is much older and dates at least to 1838.

Conventional wisdom was used in a number of other works prior to Galbraith, occasionally in a positive
or neutral
sense, but more often pejoratively.
However, previous authors used it as a synonym for 'commonplace knowledge'. Galbraith specifically prepended 'The' to the phrase to emphasize its uniqueness, and sharpened its meaning to narrow it to those commonplace beliefs that are also acceptable & comfortable to society, thus enhancing their ability to resist facts that might diminish them. He repeatedly referred to it throughout the text of The Affluent Society, invoking it to explain the high degree of resistance in academic economics to new ideas. For these reasons, he is usually credited with the invention & popularization of the phrase in modern usage.

Accuracy

Conventional wisdom is not necessarily true. Conventional wisdom is additionally often seen as an obstacle to the acceptance of newly acquired information, to introducing new theories and explanations, and therefore operates as an obstacle that must be overcome by legitimate revisionism

. This is to say, that despite new information to the contrary, conventional wisdom has a property analogous to inertia
Inertia
Inertia is the resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion. It is proportional to an object's mass. The principle of inertia is one of the fundamental principles of classical physics which are used to...

 that opposes the introduction of contrary belief, sometimes to the point of absurd denial of the new information set by persons strongly holding an outdated (conventional) view. This inertia is due to conventional wisdom being made of ideas that are convenient, appealing and deeply assumed by the public, who hangs on to them even as they grow outdated. The unavoidable outcome is these ideas will eventually not match reality at all, so conventional wisdom will be violently shaken until it doesn't conflict reality so blatantly.

The concept of conventional wisdom also is applied or implied in political senses, often related closely with the phenomenon of talking point
Talking point
A talking point in debate or discourse is a succinct statement designed to persuasively support one side taken on an issue. Such statements can either be free standing or created as retorts to the opposition's talking points and are frequently used in public relations, particularly in areas heavy...

s. It is used pejoratively to refer to the idea that statements which are repeated over and over become conventional wisdom regardless of whether or not they are true.

In a more general sense, it is used to refer to the accepted truth about something which nearly no one would argue about, and so is used as a gauge (or well-spring) of normative behavior or belief, even within a professional context. One such example was conventional wisdom in 1950, even among most doctors, was that smoking was not particularly harmful to one's health. Conventional wisdom in 2011: it is. Another: It might be used in this manner discussing a technical matter such as the conventional wisdom was that a man would suffer fatal injuries if he experienced more than eighteen g-force
G-force
The g-force associated with an object is its acceleration relative to free-fall. This acceleration experienced by an object is due to the vector sum of non-gravitational forces acting on an object free to move. The accelerations that are not produced by gravity are termed proper accelerations, and...

Treadmill

When conventional wisdom is overthrown, outranked, or outflanked by new ideas, and the new conventional wisdom becomes established in place of the previous one, there may yet be considerable remaining affiliation to the previous regime.
