> I don't mean to spoil the fun, downvote me if this is not in the spirit, but it took me way too long to figure this out and others may be as slow as me and save some time by reading this comment:

I believed it too. The thing is, this is something no one is really incentivized to lie about. If some website says "politician did X", then your lie detector turns on, because it's worth it for lots of websites to lie or mislead about that. 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. I don't think it demonstrates much that students believed it. And I especially don't think it means anything about gullibility about information found online. Almost certainly, if it were printed in a book, they'd be even more likely to believe it.

It reminds me of a friend in high school who convinced me that he grew scallions in his bathroom. It seemed weird but he described it in some detail, how the humidity from the shower is good for them, etc. Then when I believed him he said of course I don't do that, how could you think something so ridiculous. I don't and didn't feel like believing him in this context made me gullible for the same kinds of reasons you outline, why doubt something so inconsequential, communicated 'sincerely'?

I could easily imagine an episode of Seinfeld where Kramer grows scallions in his bathroom

They'd be destroyed by the elephant showerhead.

Best response / revenge is to actually grow scallions in your bathroom.

Or at least pretend to.

Best response would be to sneak into your friend's bathroom and leave baby scallions.

In the back of the toilet.

Agreed. I think the fact that it was just "scalions" adds to the credibility.

Then they get you on the flip side when somebody does something way out there that's almost unbelievable. It took a couple of decades for Epstein to be shut down, after catching him once and him getting away with a slap on the wrist.

He may have gotten this from real story from a distant relative or family friend as this is a real hobby and the humidity is a key factor. At almost $16 for a small bottle of XO sauce[1] with the main ingredient being dried scallops, it's a highly profitable home hobby.

Green onions, not shellfish. Close!

Gotcha

I would like to know more about growing scallops in the tub. Bathtub aquaculture is the Bitcoin.

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.

given the temperature of the oceans these days, that might be true

I get just a little annoyed, a reasonable amount, when someone leans into a lie for a long time, gives details, won't give it up, and even if I started out skeptical, I eventually start to believe them, only for them to pull the rug out and call me gullible or stupid or something.

No, I just made the mistake of trusting you and your persistence!

It's an important life lesson for honest people that yes, in fact many other people will lie straight to your face with things made up from whole cloth that they have zero incentive to lie about. You think "people wouldn't literally just make something up", but they do. They do all the time.

My daughters recently showed me how easy it is to grow scallions: too easy. Just cut off the bottom inch (the white bit with little roots hairs) and stick in a jar of water by a window. A week later: a complete scallion!

My wife grows plants in our shower for that reason. Not scallions, but it's other the same story. I bet he did have plants in his bathroom and for some reason switched gears about wanting to talk about it.

Sure she does

Don't let it get to you, we live in a trust based society after all.

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.

In must cultures of the world, shared history is a consensual fiction, which is regarded as being truer than the truth.

> The thing is, this is something no one is really incentivized to lie about

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.

The British Flat Earth Society is a joke society in this vein. They amuse themselves by writing very erudite debunkings of the nefarious Spherical Earth conspiracy theory, and sending strongly worded Cease & Desist notices to NASA.

Add in that the animal world is full of wacky creatures that don't fit heuristic models for plausibility.

People thought the Platypus was a hoax was it was initially discovered. It is real.

Add the propensity to colloquially grant newly discovered things names that borrow from existing things: sea cow, catfish, etc. so why couldn’t there be something called a tree octopus?

Today I learned that a tree crab is a thing. I knew a tree lobster was a thing. There is something that could plausibly be called a tree clam.

> Add the propensity to colloquially grant newly discovered things names that borrow from existing things: sea cow, catfish, etc. so why couldn’t there be something called a tree octopus?

There could be. The name of the animal isn't what gives the lie away.

People still call the dropbear a hoax.

Is it not? The Wikipedia article literally has in the tagline: famous hoax…

That's certainly what the dropbears want you to believe.

They are pretty good with web browsers and typing

Don’t believe everything you read on the internet.

There are people who say birds aren’t real, or that Australia isn’t real, or that the earth is flat.

> Add in that the animal world is full of wacky creatures that don't fit heuristic models for plausibility.

The animal involved not meeting heuristic models for plausibility may be something that should trigger skepticism, but its not the thing that should tell you this is a lie.

> The thing is, this is something no one is really incentivized to lie about. If some website says "politician did X", then your lie detector turns on, because it's worth it for lots of websites to lie or mislead about that.

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 don't think it demonstrates much that students believed it.

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.

> 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.

I'm just going to leave this here

>> 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. The reasons for this dire situation include: decimation of habitat by logging and suburban encroachment; building of roads that cut off access to the water which it needs for spawning; predation by foreign species such as house cats; and booming populations of its natural predators, including the bald eagle and sasquatch.

> fictitious nation-state

Are you referring to Cascadia? That's a perfectly non-fictional name for the region (https://en.wikipedia.org/wiki/Pacific_Northwest).

Or maybe I missed another reference?

Cascadia is a perfectly non-fictional name for the region, the Republic of Cascadia Department of Cephalopod Conservation, OTOH, is an extremely fictional agency of an equally fictional government.

Well there are mudskippers [0] [1] which can end up crawling up to and resting on branches and trees growing out of the water. So while it seems untrue, it wouldn't be far fetched for a species of octopus adapted to end up doing so, especially if the out of water circumstances are narrow enough(very temporary, trunks & branches very close to water, etc).

[0] https://en.wikipedia.org/wiki/Mudskippers

[1] https://www.youtube.com/watch?v=LNCYSCHipvw

There is a species of octopus that does crawl out of the water to hunt (Australian, of course), but they don’t climb trees.

https://www.youtube.com/watch?v=ebeNeQFUMa0

Well that Octopus and I have a lot of common.

* live in Australia

* love to eat Blue Swimmer Crabs

And there's enough improbable animals out there it doesn't sound crazy. Shrimps that live in the desert, crabs that live on land, frogs which live in trees, lobsters and mussels and shrimps and jellyfish that live in fresh waters.

> this is something no one is really incentivized to lie about.

'Click here to donate to my gofund me to save the amphibious octopus.'

> 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.

Some fish-looking sea creatures are actually mammals. Sea horses have pregnant males. Deep sea fish look like horror monsters. A fresh water octopus just isn't that unbelievable.

The incentive is practice in the conspiracy ideas market. It's fun to fool people, and these days it's profitable. Enter a popular conspiracy forum and you'll see how many are there to sell things. They create their own market.

So I immediately googled because it rang an alarm bell that some octopuses would develop specialized air-breathing apparatuses — that conflicts with my basic understanding of evolution. But I wasn’t googling it to falsify, but rather to see from a more ‘objective’ source if/how this occurred.

I think it’s the same basic principle as hanging up if a relative calls you begging for money or proclaiming to be kidnapped and calling you back. The costs for double-checking incredible claims is often not that high.

> And I especially don't think it means anything about gullibility about information found online

You really think it means absolutely _nothing_ about this topic? It's literally an example of people believing what they read online! I think you're having an overly defensive reaction to probably falling for it.

> 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 site does include a call to action. I think that’s the point where one needs to question things. I certainly don’t want to be the one that writes my Congressperson about this “hoax”. The next time I need something truly important, I’m likely to fall to the bottom of the pile.

Even widespread information can be false. For instance, you can not "catch cold" by getting cold, the name of the illness is misleading.

I mean absence of incentive to lie is far from universal criteria to distinguish false information.

Of course they would be more likely to believe a book, they should be. That's the point: making a web page is super easy, anyone can do it. Making a convincing fake issue of a science magazine would be a lot harder, it's highly unlikely someone would do it just for a joke.

But really, if there were something as bizarre as a tree octopus, you would have heard of it.

If no one is incentivized to lie about it, is anyone incentivized to tell the truth about it?

i know enough about octopuses and forests that i don't have to care about the author's motives--i just have to skim the text or look at the photoshop. thinking a tree octopus is real because you saw a lot of words and can't relate them to a nexus of disinformation is a perfect example of gullibility

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".

> 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

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?

call me arrogant but i won't stoop to the level i have to be at to take your question seriously.

do i think i'm as intelligent as anyone, or that everyone is as intelligent as me? of course not. but i do think your standard for gullibility is too high if you don't think believing the linked article satisfies it.

Stoop? I challenge you with a perfectly valid example of an unlikely animal, and your response is to claim I'm somehow, what, failing to argue at your level?

I suppose that's enough to make my point for me.

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.

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).

Platypus seriously? If you're going to make up an animal, at least try to give it a realistic sounding name.

See, if they had said the tree octopus is found in some remote corner of Australia and has a pouch to raise its young, more of us would buy it...

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.

Which of the following are real?

- Tree lobster - Tree crab - Tree clam - Tree fish

you're presenting an entirely different scenario from the OP. try again with photos, maps, propaganda posters, and a few thousand words on each, and replace your question with an assertion. in absence of that i do a quick search and find out three are real and one is not but may be a colloquial term referring to a sporadic phenomenon

And the first time I read about those crabs, I checked Wikipedia to see if they were real too. Too many hoaxes on the Internet, but most of them are trivial to find out if they're real.
