@Brandon Sims (and all others convinced this was a confession)
Here is some extra information regarding sarcasm and the written English language from a genuine word nerd:
You've been quoted as saying, a number of times on this thread, that we cannot 'prove' he was being sarcastic. I think you're right about that to some degree. MB is focused more on empirical evidence, whereas detecting sarcasm (especially when written) is a bit more subjective and open to interpretation.
A pre-algebra teacher wouldn't ask their class to write a 1,000 word essay on why x equals 2 in the equation 127-x=125, would they? There isn't much to say about it because mathematical equations are objective--not swayed by personal belief, just factual. Correct, incorrect. Likewise, an English teacher isn't going to fail every student who doesn't understand that the rabid dog in To Kill A Mockingbird represents the monster within us all, or whatever this particular teacher believes it's symbolic of. That's because this is a subjective subject--it's up for personal interpretation, and merits can be argued on every 'side' of the debate.
Sarcasm is incredibly complicated in all of its forms. When you're face-to-face with someone who is being sarcastic, you can look and see clues as to their sarcasm. They might roll their eyes, raise an eyebrow, smirk, or shrug. If you were on the phone with someone, you could hear their tone change. They might enunciate some words and draw out others. Their volume and infection might change. These are clues.
If I was standing in Starbucks tomorrow morning and I overheard a conversation, I'd be able to hear a woman talk to her friend and have a pretty good idea she was being sarcastic, even without seeing her and knowing her situation. "I can't WAIT to see
Scott tonight," she might say, and I'd know she didn't want to see this Scott guy because she put effort on the word 'wait' and said 'Scott' like most people say 'fungus'. These are clues. If I was looking at her while she said this, I'd see that she rolled her eyes. Even though I know nothing about this woman and the state of her relationship with a man named Scott, I can guess that she doesn't like Scott for whatever reason.
Now, if I knew her, I'd know the context: Scott was an old flame that she has to meet for business tonight and he constantly rubs her lack of ability at winning Frogger on Atari 2600 in her face, so she doesn't want to see him.
Now, what about just reading the sentence plain?
"I can't wait to see Scott tonight."
How can we possibly prove OBJECTIVELY that the above sentence is sarcastic, with not even a single emoji or snarkily italicized word to help us?
We can't. We'd have to argue our points using logic and deductive reasoning. We'd have to find a context for this situation. Even if we hacked this woman's computer (which MB members don't and wouldn't do

) and found 12,000 bookmarks about how to win Frogger on 2600 and 200 emails from Scott mocking her pixelated hopping abilities, we still wouldn't be able to prove the sarcasm conclusively without a single shred of doubt. That isn't how sarcasm works. It's subjective.
Again, we need to look at context.
A late-night adventure through a Google Scholar wormhole found a number of other studies relating to the art of detecting sarcasm.
Here is another paper about sarcasm. The same beautiful idea comes up in this one, just like the last one I mentioned, here:
External Quote:
Sarcasm sentences can be used almost in all topics. They
can take variable grammatical structures. Also, to under-
stand sarcasm, one has to know the context of the sentence.
For instance, the sentence "I love being rich" is not sarcas-
tic by itself. However, if you know that the speaker is poor,
you will decide that this is a sarcastic sentence. Therefore,
to detect sarcasm, you have to have prior knowledge about
the subject or sarcasm, which might not always be avail-
able.
So, when you say:
The point is you took someone's confession in a memoir and applied you own spin on it based on the subtext you read. Based on the conclusions you have drawn not based on any fact or logic that's an assumption to say he was kidding when all evidence points otherwise including his own words. But again. I know what your gonna say
We have to repeat ourselves because sarcasm literally means saying one thing with ones' "own words" but meaning the opposite and to tell if something is sarcastic we have to think about the context (situation behind) and subtext (underlying meaning) of the so-called confession.
We need to look at words to properly "prove" there is sarcasm present.
One such analysis puts it more succinctly than I can:
The use of 'even' as an adverb indicates a statement that is surprising, extreme, or ridiculous.
The idea that the author could consider the belief that he was "part of a secret cabal working against the best interests of the United States" simultaneously surprising and true, doesn't scan.
"Deviation from the English language" as they'd call it on Just A Minute.
From this somewhat superfluous sentence that Rockefeller said, we can sense that there's some sarcasm going on, that it isn't an exact confession of exactly what he is meaning.
And we have further evidence and reasoning for this here:
What do you think he meant by "secret cabal"?
If it's secret, then why would he admit to being in it? Isn't that the first rule of secret cabals - that they are supposed to be secret?
So though we don't have a conclusive test for sarcasm yet that we can dip in a sentence, shake it off a bit and look at it until we see two blue lines for sarcasm and one for a lack thereof, I am pretty sure that we can comfortably say that the evidence we have points to this being sarcasm.
(we can also comfortably say that i get way too excited about the nuances of communication, dear god)
