I would think most American’s would think the following line to be accurate:
1. “George Washington was the first President.”
If you saw that in wikipedia, it would seem to be a valid statement, and you might accept it as fact. It is true, isn’t it?
Well, no, it really isn’t true, and someone editing a wikipedia document might find a subtle error, and correct it.
You see, the line says that George Washington was the first President, not that:
2. “George Washington was the first President of the US.”
That second line is more accurate.
The problem is with the word “President.” A company, a trust, an organization, a society, a Masonic lodge, or any other organization might have a President. George Washington wasn’t the first person ever to be endowed with the title “President.”
If line one were posted in wikipedia, someone might edit it to read like line two.
But line 2 isn’t accurate either.
Someone might realize there is no country on earth that has the name “US.” The name of the Country of which George Washington served as the President is, “The United States of America.” That is more accurate still.
So, the line should read:
3. “George Washington served as the first President of the United States of America.”
Are you happy with that? Oops.
Someone might come along and say, “but wait, from the signing of the Declaration of Independence (July 4, 1776), until the ratification of the Constitution of the United States of America (March 4, 1789), there were other Presidents who served under the “Articles of Confederation.” Article IX of the Articles of Confederation specifically called for the election of a President. John Hanson, of Maryland, was elected the first President. The Articles of Confederation (Article I) called the new nation “The United States of America.” That would mean that John Hanson was the first President of the United States of America. How can we fix that quandary?
4. “George Washington served as the first President of the United States of America under the Constitution.”
(The Articles of Confederation only allowed a President to serve a one-year term during any three-year period, so Hanson only served from November 5, 1781 until November 3, 1782. He was the first President to serve a full term after the full ratification of the Articles of Confederation. Six other presidents were elected after him - Elias Boudinot (1783), Thomas Mifflin (1784), Richard Henry Lee (1785), Nathan Gorman (1786), Arthur St. Clair (1787), and Cyrus Griffin (1788) - all prior to Washington taking office.)
George Washington was definitely not the first President. He wasn’t even the first President of the United States of America. He was the first President of the United States of America under the Constitution we follow today.
But, it sure is easier to say, “George Washington was the first President.”
This is precisely why wikipedia works: It is open for anyone to make corrections to it. This is also precisely why wikipedia is subject to failing. If you read the following line in wikipedia, wouldn’t you like to correct it?
“George Washington was the eighth President of the United States.”
Yes, you would want to correct it. You’d know that wasn’t correct. Everybody knows that wasn’t correct (don’t they?) Even though, as worded, it is precisely correct!
So, can wikipedia be wrong? Of course. Can it be corrected? Yes, you can edit it. Will you be making it more correct, or more wrong though? That, my friends, is why it is tough to edit wikipedia accurately, or to rely on it completely. It changes, it is fluid, and it may or may not be right—depending on how good “we the people” are at editing it.
And finally, since it is open to changes, it is possible for someone to come along and completely abuse their trust as an editor too, and change the first line to read, “George Washington was a traitor; a slave-holding killer, who led the colonials in a rebellion against their proper authority.” That sentence might be right too, but it doesn’t serve the interests of the public—it just vents someone’s aggression.
So when using wikipedia as a source, realize that any “open source” document makes a poor reference.
Don't use it on a "serious" report. Do use it as a place to learn from. Often, it will give the references for it's claims too. Those references may be better sources. (May be--but watch for political "tainting.")
