2+2 = not what you think

felipec.substack.com

Changing someone's mind is very difficult, that's why I like puzzles most people get wrong: to try to open their mind. Challenging the claim that 2+2 is unequivocally 4 is one of my favorites to get people to reconsider what they think is true with 100% certainty.

I specified "in Z/4Z" the first time I made my statement, I referred to modular arithmetic the second time, I clarified my statement to the literal same when you asked.

You are trying to distract from what you said, this is what you said:

But the existence of modular arithmetics doesn't make 2+2=4 incorrect. It merely makes 2+2=0 another representation of the same statement. So "most people" remain correct.

You also said:

Did you just claim less than 0.0001% of people think 2+2=4?

It's very clear what you said:

  1. Most people think 2+2=4 is true

  2. The existence of modular arithmetics makes 2+2=0 another representation of the same statement

  3. 2+2=0 (mod4) is not the same statement as 2+2=0

There are facts. I'm not misrepresenting anything you said.

If by 2+2=0 you didn't mean 2+2=0, but 2+2=0 (mod 4), then that contradicts your initial claim that most people think 2+2=4 is true, because to be the same statement it would need to be 2+2=4 (mod 4).

So either your claim (2) is false becase 2+2=0 (mod 4) is not another representation of 2+2=4, or it's unrelated to claim (1) because 2+2=4 (mod 4) is not the same as 2+2=4.

Either way your argument is invalidated.

But it's pretty clear that you meant 2+2=4, not 2+2=4 (mod 4), because the former is what most people think is true. You are trying to antagonize me to distract from the fact that your argument has been blown up to bits.

You're trying to cut out the context, which makes it a misrepresentation of me. Retract and apologize.

You know what you tried to do, and now you are trying to hide it. Even when one tries to be as charitable as possible, there's only one likely conclusion: you are arguing in bad faith.

You are trying to distract from what you said

No, I'm trying to explain what I said, because you keep removing the context:

  1. 2+2=0 (mod4) is not the same statement as 2+2=0

I said 2+2=4 in standard arithmetic is not the same statement as 2+2=0 (mod 4). I insisted on making this explicit, because it came up on the context of mod 4. And because I suspected you were trying lead me to a contradiction, so I made sure to speak clearly, proofing myself against it.

So if you cut out the important context, and then try to construct a contradiction that doesn't work with the context included, you're misrepresenting me.

Retract and apologize.

(Assuming here you meant to write 4 instead of 0, but otherwise it would just be an even worse misquote, so I'm charitably assuming it's a typo.)

But it's pretty clear that you meant 2+2=4, not 2+2=4 (mod 4), because the former is what most people think is true.

I meant "2+2=4", "in Z/4Z" omitted, as in your original setup*. When it's about people's reaction to the statement, formulation is important.

*But in my case it was available from context, whereas in your example it was deliberate misdirection.

People think it's true, while they're denied the context. But given the full context, which changes the meaning, it's still true.

It's also quite peculiar that you're doing what you're accusing me of: I pointed out you were contradicting yourself, you tried to weasel away, and when I nailed you down, you tried to ignore it. Do you stand by the statement

(2+2=4 (mod 4)) exists, which is not the same as (2+2=4), and you finally accept that they are two different things.

?

I said 2+2=4 in standard arithmetic is not the same statement as 2+2=0 (mod 4).

You keep omitting the context of your own statements, you clearly implied that "more than 0.0001% people think 2+2 is necessarily 4", obviously you meant in standard arithmetic, since very few people know that 2+2=4 (mod 4) even exists. And you also accepted 2+2=4 (mod 4) is not the same statement as 2+2=4, therefore it's entirely possible for more than 0.0001% people to think that 2+2=4, and less than 0.0001% people think that 2+2=4 (mod 4).

you clearly implied that "more than 0.0001% people think 2+2 is necessarily 4", obviously you meant in standard arithmetic, since very few people know that 2+2=4 (mod 4) even exists.

Obviously I meant "with unspecified context", because that was the example we were talking about. Yes, people don't know you're sneakily talking about modular arithmetic - but "2+2=4" is still true, so people are giving the correct answer, despite the confusion.

And you also accepted 2+2=4 (mod 4) is not the same statement as 2+2=4

Can you just fucking stop misrepresenting me? That would be great, thanks.

And you also accepted 2+2=4 (mod 4) is not the same statement as 2+2=4

Can you just fucking stop misrepresenting me? That would be great, thanks.

False. I'm not misrepresenting you, you literally said they are not the same statement right here.

Do you believe that (2+2=4) and (2+2=0 (mod 4)) are "the same statement"?

But just for the record, the answer is no then.

It took you 5 comments where you tried to misdirect, but you finally accepted it, and because now it's clear that admission dismantles your whole argument, you are trying back down from it, but you did accept it.

You cut out the part where you specified (2+2=4) in standard arithmetic before I answered. That's the misrepresentation.

Since you seem to have hard time understanding context, I'll repeat my actual statement with the context explicit:

(2+2=4 in standard arithmetic) and (2+2=0 (mod 4)) are not the same statement.

With that cleared up, any further questions?

You cut out the part where you specified (2+2=4) in standard arithmetic before I answered. That's the misrepresentation.

False. That is understood, since you argued that (2+2=4) is always standard arithmetic, so no context is necessary.

(2+2=4 in standard arithmetic) and (2+2=0 (mod 4)) are not the same statement.

This is precisely what I interpreted, there is zero misrepresentation.

Now that you have repeated what I already said, except making the standard arithmetic explicit, instead of implicit, let's go back to the context that you keeping trying to run away from:

You very clearly said:

Did you just claim less than 0.0001% of people think 2+2=4?

As I pointed out numerous times, by 2+2=4 in this context you meant in standard arithmetic, which is what I interpreted correctly from the start, and I stated to you multiple times already.

You finally accepted that (2+2=4 in standard arithmetic) and (2+2=4 (mod 4)) are not the same statement, therefore even if 99.9999% of people think (2+2=4 in standard arithmetic) that does not equate to 99.9999% people thinking (2+2=4 (mod 4)), because they are different statements (as I already explained).

Therefore when you said "We think 4, 4 is 0", you were wrong.

Your statement expanded is "We (99.9999% people) think 4 (in standard arithmetic), 4 (in standard arithmetic) is 0 (in standard arithmetic)", which is clearly wrong. Period.

you argued that (2+2=4) is always standard arithmetic

No, I didn't. If you believe otherwise, cite where I said it. Or stop misrepresenting me.

As I pointed out numerous times, by 2+2=4 in this context you meant in standard arithmetic

So you're "pointing out" to me what I meant. Have you considered that I can read my mind better than you can? After all, when someone talks about your position elsewhere , you're quick to call it out as assumptions. And when I offer clarification, you ignore it, only to repeat your strawman two posts later.

Obviously I meant "with unspecified context", because that was the example we were talking about. Yes, people don't know you're sneakily talking about modular arithmetic - but "2+2=4" is still true, so people are giving the correct answer, despite the confusion.

That was my clarification. I've had a lot of patience with you, but I can't really have a discussion with someone who talks to their own caricature of me and ignores what I actually say.

if 99.9999% of people think (2+2=4 in standard arithmetic) that does not equate to 99.9999% people thinking (2+2=4 (mod 4))

You weren't asking about 2+2 (mod 4) though. You were asking "2+2=" without context, and people answer "4", which is correct.

If they interpret the meaning of the string "2+2=" different than you, that's not anyone being wrong, that's just a misunderstanding caused by your bad communication. But luckily the misunderstanding doesn't matter, because the answer is correct in either interpretation.

You weren't asking about 2+2 (mod 4) though.

No, I was asking about 2+2 (no context), as I have been made it clear countless times.

You were asking "2+2=" without context, and people answer "4", which is correct.

False. 2+2 (standard arithmetic) is different than 2+2 (mod 4), and 4 (standard arithmetic) is different than 4 (mod 4).

After many questions you finally accepted that:

(2+2=4 in standard arithmetic) and (2+2=0 (mod 4)) are not the same statement.

Are you going to backtrack from that claim?

What is this place?

This website is a place for people who want to move past shady thinking and test their ideas in a court of people who don't all share the same biases. Our goal is to optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.

The weekly Culture War threads host the most controversial topics and are the most visible aspect of The Motte. However, many other topics are appropriate here. We encourage people to post anything related to science, politics, or philosophy; if in doubt, post!

Why are you called The Motte?

A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently, it's an element in a rhetorical move called a "Motte-and-Bailey", originally identified by philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial but high value claim to a defensible but less exciting one upon any resistance to the former. He likens this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired propositions to which one retreats when hard pressed."

On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
