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.

By checking whether or not the person considers the possibility of the claim being not necessarily true. And if not, whether or not the claim is substantiated by evidence or reason.

By "the claim being not necessarily true", are you referring to the possibility that the claim's originator is expressing a belief contrary to truth, or the possibility that the claim's recipient is interpreting the claim differently in such a way as to make it the received belief incorrect? The examples in your original post are of the latter, but I'd usually understand substantiation as a property of a belief having already been shared and correctly interpreted.

It would also seem that the former is far easier than the latter. If you know that you're correctly understanding the belief being expressed by a claim, then you can simply compare the belief to your own worldview, and doubt it according to how likely the alternatives appear to be true. But evaluating how much you may be misinterpreting a claim is a far different challenge: you have to map out the space of possible beliefs in the originator's mind that could have plausibly led to that particular claim, accounting for how the originator's thoughts might look far different from your own.

Neither. I said the claim's originator considers the possibility that the claim might not be necessarily true. This is expressed in modal logic as ◇⊥ (possibly false), or ¬□⊤ (not necessarily true).

It's not about whether or not the claim is really true or not, or if it has been substantiated... It's about you believing it might be false.

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!

Check out The Vault for an archive of old quality posts. You are encouraged to crosspost these elsewhere.


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.


New post guidelines

If you're posting something that isn't related to the culture war, we encourage you to post a thread for it. A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a submission statement. A submission statement is required for non-text sources (videos, podcasts, images).

Culture war posts go in the culture war thread; all links must either include a submission statement or significant commentary. Bare links without those will be removed.

If in doubt, please post it!
