People Are Entitled To Their Own Opinions But Not To Their Own Facts

Bernard Baruch? Daniel Patrick Moynihan? Rayburn H. Carrell? James R. Schlesinger? Alan Greenspan?

Dear Quote Investigator: A family of popular sayings highlights the difference between opinions and facts. Here are three thematically related expressions:

(1) Everybody has a right to their opinion, but nobody has a right to be wrong in their facts.

(2) You are entitled to your own views, but you are not entitled to your own facts.

(3) People are entitled to their own opinions, but not to their own facts.

These sayings do not have identical meanings, but it is helpful to group them together while exploring their provenance. Financier Bernard Baruch and politician Daniel Patrick Moynihan have been given credit for these thoughts. Would you please explore this topic?

Quote Investigator: The earliest match located by QI occurred in an Associated Press article from 1946. Bernard Baruch was quoted when he complained about an opponent’s assertions which he believed were inaccurate. Boldface added to excerpts by QI: 1

Every man has the right to an opinion but no man has a right to be wrong in his facts. Nor, above all, to persist in errors as to facts.

Below are additional selected citations in chronological order.

The Plural of Anecdote is Data

Raymond Wolfinger? Roger G. Noll? Richard F. Fenno Jr.? Daniel Patrick Moynihan? George Stigler? Anonymous?

Dear Quote Investigator: An anecdote is a single fact or datum. When many of these facts are combined the collection is naturally called data. Apparently, a social scientist coined the following saying:

The plural of anecdote is data.

Would you please help me to find a citation?

Quote Investigator: The earliest known instance appeared in a 1980 book chapter titled “The Game of Health Care Regulation” by Roger G. Noll. This citation is listed in the valuable reference “The Dictionary of Modern Proverbs” from Yale University Press. Emphasis added to excerpts by QI: 1

Most of the evidence is anecdotal. Nevertheless, in the words of a leading political scientist, Raymond Wolfinger, the plural of anecdote is data, and the data seem to be consistent with the theory.

This is an illuminating statement, but it is important to recognize that data used in scientific experiments should be gathered in a systematic manner according to a well-defined protocol. A haphazard group of anecdotes typically do not yield a good data set. Hence, the negation of the expression above is an adage to some researchers:

The plural of anecdote is not data.

This adage is explored by QI in a separate article here. Below are additional selected citations in chronological order.
