An argument from authority[a] is a form of argument in which the opinion of an authority figure (or figures) is used as evidence to support an argument.[1]
The argument from authority is a logical fallacy,[2] and obtaining knowledge in this way is fallible.[3][4]
A common cognitive bias is that it is a practical and sound way of obtaining knowledge that some presume to be correct when the authority is universally accepted, though some consider this to be an obvious circular reasoning and repetition of an argument from authority[1][5][6][7][8][9][10] and others consider to be a very weak defeasible argument or an outright fallacy.[2][11][12][13][14] The mere fact that an authority can be wrong or decide to lie means any appeal to authority must be further proved through valid logical deduction of the evidence anyway.[15][16][17]

The argument from authority has had many detractors throughout the long history of logic. It is not difficult to see why this is the case. After all, the argument resorts to the use of opinion to support a claim rather than a range of more objective sources of support (e.g. evidence from experiments, observations, or measurements)...These difficulties and other weaknesses of authority arguments have found these arguments maligned in the logical treatises of several historical thinkers...'argument from authority has been mentioned in lists of valid argument-forms as often as in lists of Fallacies'
