There are large crabs that climb trees and eat coconuts.

There are fish that can survive on dry(-ish) land for extended periods of time.

And don't get me started on the utterly bizarre slime mold.

The number of species that defy our expectations is countless.

Bluntly, there's a lot of arrogance in the claim that anyone should be able to easily and automatically rule out the existence of some species based on their personal knowledge, and that anyone who fails to do so is "gullible".

some, certainly yes.

i don't think anyone would disagree that some claims are more plainly ridiculous than others. i'm replying to someone who let themselves be convinced the tree octopus was real by a page picturing an octopus climbing a tree. let's not abdicate our regard for common sense.

I think you'll find your idea of "common sense" is perhaps not so universal as you think.

For example, why is a tree octopus any less likely than the platypus, a venomous aquatic mammal that has a beak, lays eggs, and detects prey by sensing electric fields like a shark?

Re:The Pacific Northwest Tree Octopus by hoosieree on Sunday July 16, 2023 @01:24PM (#36749417)

you asked me how i would ascertain that an animal documented to exist is more likely to be real than a hypothetical animal depicted with _a photoshop of a different animal climbing a tree_, as if there is no reasonable expectation of intelligence or intuition for an abled, functioning adult

the difference between people who initially believed this and those who didn't is gullibility, and this is a great example of gullibility because of how outlandish the claim is and appears to be. that's all i'm arguing. the counteraguments i see boil down to "but if someone is gullible enough, they'll think it's actually not outlandish and accept it on face value" which is not contrary to what i'm saying.

if you were one of the gullible ones, sorry! sucks to be more deficient than others in some way, but we all have deficiencies.

Re:The Pacific Northwest Tree Octopus by HelloMcFly on Sunday July 16, 2023 @03:07PM (#36750390)
I think the point is that it seems highly unimaginative (or perhaps just highly unempathetic, if there's a difference in this situation) to not see how a casual reader could just take it at face value and go on with their day. This seems especially plausible to me if I think of someone who knows little of the natural world beyond the odd thing they've come across on the internet, doubly so if not from America. At face value it seems as plausible as anything else, with just a bit of scrutiny it clearly doesn't hold up.

But I suppose you have your deficiencies too, same as those who thought it to be real (however briefly).

Re:The Pacific Northwest Tree Octopus by Michelangelo11 on Sunday July 16, 2023 @03:02PM (#36750353)
The reason the tree octopus as described by that page seems obviously, totally fake to me is the absolutely janky "photo". Let's count the issues:

1) obviously photoshopped -- a real octopus on a tree branch would look totally different, it would sag in some places, it would affect the pine bristles underneath, it wouldn't have a shadow that makes it look like it's hovering an inch above the branch, etc. Also, that octopus image looks totally out of proportion, but I can't pin down why -- I _think_ it's because the level of detail is higher than for the branches.

2) It looks exactly like a regular octopus. Not only should an animal the size of a small bird have different proportions from a regular octopus (compare e.g. bats and fruit bats, or cats and tigers), but it should also look only distantly related to a regular octopus because it's adapted to a totally different biome.

All that leads me to the following conclusion: Common sense, in the sense of broadly understanding how the world works, really is what prevents you from getting fooled, and the more things you understand, the less likely you are to get fooled. Also, the more information a hoax has, the more likely it is to get exposed, because just one sufficiently glaring inconsistency can sink it.

I don't think it's lying in the sense of trying to make someone else actually believe it. It's just a form of creative fiction writing. It can be a lot of fun to write in this mode; when well done it's a pleasant kind of erudite humor because to produce it (and get it) you have to be somewhat knowledgeable in the topic. Mockumentaries might be the film/TV equivalent. Unfortunately (especially for certain subjects) it also confuses and causes strife if readers take it too seriously.

> It would be very hard to go through life questioning the veracity of every inconsequential bit of information that no one has an incentive to lie about

The issue is you may not understand or fathom the reasons someone may lie about something. Imagine the strange traditions that leaders have maintained throughout history to help control their subjects. To those subjects, I'm sure they weren't even imagining that these things they thought were spiritual were just fictions.

As for my point - yes you should try go through life with a certain level of curiosity and apprehension when people tell you things. I feel like a lot of our societal issues are a result of things continuing for no good reason, just because we've done it in the past. It's become fairly easy to fact-check, and while not popular at parties, it's important if you're actually trying to learn and build an accurate mental model.

If people were more comfortable questioning all aspects of our society (and if society was receptive to the criticism), I feel like we would be better off.

The purpose of misleading about “politician did X” is to sell a call to action. Any time there is a call to action supported by a claim, there is an obvious motivation for misrepresentation (the very same one present when “politicia did X” is the claim.) This contains a call to action, ergo, it has an obvious motivation for misrepresentation.

I think it demonstrates a lot that half of 13-year-old students in the US study believed a page which referenced a fictitious nation-state in the Pacific Northwest was reliable, leaving aside the other indicia of deception. Though whether what it says is about internet literacy or complete failure of education on geography perhaps less clear.

>> Although the tree octopus is not officially listed on the Endangered Species List, we feel that it should be added since its numbers are at a critically low level for its breeding needs.

You can use the Polynesian palm scallop, which attaches itself to the damp bathroom wall in picturesque clusters like roof shingles. It is an aerial filter feeder, capable of subsisting on household dust (which is mainly organic matter) though for faster growth, one can use a fine-mist spray of blended sausage meat and soggy marrowfat peas. They are also excellent for repelling rats, their natural predator, by emitting sharp bursts of ultrasound when the rodent's presence is detected.

The problem is in getting hold of them, as trade in this protected species is illegal.

I was talking to my kids about this sort of thing recently, but in the context of scientific scepticism.

I don't think believing makes you gullible, is just that the consequences for believing in this case are negligible. At worst, you repeat the story to someone else, as second-hand fact. Mostly likely however, you'd never think of this conversation again, and it would have no effect on your behaviour. I think it says much more about the person telling the lie (this is a shitty thing to do to a friend) than the person accepting the lies.

Extraordinary claims may require extraordinary evidence, but it really only matters at the point where believing those claims affects one's behaviour and the consequences are tangible and different from refutation of those claims.

Pablo Picasso once said "Art is the lie that reveals the truth." Except that he didn't really say that. What he said was "Art is a lie that makes us realize truth, at least the truth that is given us to understand." (The Arts: An Illustrated Monthly Magazine Covering All Phases of Ancient and Modern Art, NYC, 1923)

Is there a subtle truth to your friend's lie? It need not be related to scallions. We perceive the world through narrative. Perhaps your friend was introducing a fundamental truth through the revelation of scallions growing in a bathroom. Or at least that's how we would interpret it on my home planet of Zeta Reticulii IV. Of course the "fact" that I'm from Zeta Reticulii IV is a lie. I grew up in Texas. You can make your own decisions regarding the relative adherence to consensual reality between Texas and Zeta Reticulii IV.

Perhaps the story of growing scallions in the bathroom is nothing other than the creation of a shared history. Does it matter that history is counter-factual? We're social beings. We do things like that.

This is an outdated approach to information literacy, unfortunately.

To make money today, all one needs is attention. Therefore there is a universal incentive to say anything attention-grabbing.

Many people are making a living today by saying things that are at least as ridiculous as a tree octopus, for example that the COVID vaccine has a microchip from Bill Gates in it, or that there is a secret global plan for everything revealed by a guru nicknamed Q.

Information needs to be evaluated by a consistent approach that takes into account the source, cross-checking with other sources, and (especially) cross-checking with what is already known.

For example this fake animal story is easily caught by checking it against other trusted sites like Wikipedia, the Smithsonian, major news services, etc, and by testing it against existing knowledge of marine life: octopuses don’t have lungs, and therefore cannot persist out of water for more than short periods of time.
