Firstly, a shout out to marleycat who alerted us to this in the first place

----------------------------------------

Remember in grade school, when your teacher started drawing intersecting circles on the chalk board, before you even knew what "intersecting" meant?

Well, don't feel bad if you don't remember, and don't even feel too bad if you still don't get them right.

Because, neither does the presidential campaign of one.....................Mitt Romney.

That's right, Harvard grad Mitt Romney, and his supposedly stellar staff of big-brained bozos..............................got it WRONG.

A Venn diagram is designed to show all possible logical relationships between a finite collection of sets.  Put more simply, you label the left circle with one factor, the right with another, and the center with something that has the properties of both.  I think Mitt was trying to use what's called an "intersection of two sets" diagram.

Like this:

And, well, he fucked it up big time.................

and that wasn't the only one they fucked up, either.

Mitt, this one demonstrates how the intersection diagram SHOULD work:

And now, some others have started a new meme, with some doozies like these:

Now, while these are, in fact, great examples, I think this community could probably top them.

Go here to make your OWN Venn Diagram, save it, and post it here

UPDATE: - More diagrams

And lastly, a rather pretty, and non-political venn diagram for Steve Miller Band fans, done by The Angry Mathematician & Australian Numeracy Ambassador Simon Pampena (as far as I can tell):

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
