What amazes me about spiders is their complex unlearned behavior. No trapdoor spider learns how to build a trap. No orb weaver learns how to spin a web. Trap/web building behavior is entirely programmed in their DNA.

I think about this a lot in the context of conversations about intelligence. If spiders can have complex behaviors hard-coded, humans certainly do too. (In other words, the Tabula Rasa theory is wrong.) The ability to learn language and emotion are certainly two examples. We are pretty good at certain things (learning language, picking up social cues) and relatively bad at others (calculating an 18% tip).

So if you’re going to measure “intelligence” the first thing you’ll need to do is choose what to measure. What questions do you ask? You might be inclined to pick things we humans think are important. But then that’s not an objective universal measurement, at best it’s yardstick for human cognitive abilities.

We struggle to define intelligence, much less measure it.

When I was at school a million years ago "smart" kids were ones who learned to read fast, did numbers well, and had good memory recall.

Then along came computers, which had perfect memory, did numbers really well. So "intelligent machines?"

Obviously not, so we tweaked our measure of intelligence. Perhaps to include writing well, or learning quickly. Which, um, computers now do.

But we still view the computers as "not intelligent" but I'm not sure what measure we'll use now. Something to do with art or music? Hmm, no, wait, that's no good either....

(PS schools still mostly measure numbers and memory....)

How do you differentiate between a student who actually understands the topic and one who is just able to produce a convincing essay about it?

More generally, how do you measure ‘actual understanding’, if not by judging the student's output?

"if not by judging the student's output"

And someone who can produce a convincing essay usually has understood the topic (unless he copy pasted it). And when there are doubts, one can ask that student specific questions.

You asserted that the student should “not just [be] able to produce nice sounding words”. What do you suggest output is if not words (nice sounding or not)?

And someone who can produce a convincing essay usually has understood the topic (unless he copy pasted it).

Then, what is the difference between a convincing essay (‘nice sounding words’) produced by a human, and similar words produced by an LLM?

After all, even today, students are passing ChatGPT’s work off as their own. Does this then demonstrate understanding by the student or by ChatGPT?

And when there are doubts, one can ask that student specific questions.

If an LLM can answer specific questions about a subject, does this demonstrate true understanding? If not, why not?

If it could, I would say there is understanding. But in every area where I have expertise, I see LLMs failing my questions. Just like a bad student would, who memorized textbooks, but did not connect or process the knowledge in any way.

Sometimes the word “intelligent” is used by someone who sells IQ tests.

Sometimes the word is used by someone who sells the idea of a computer that can think like a human.

Schools deem a child smart when that child excels at tasks that the school assigns to them. I've those tasks were simply to read and add. Then those tasks included writing and remembering. What tasks do schools demand of children today?

It seems that intelligence is a term that we apply to people who consistently excel at the mental tasks assigned to them, no matter what those tasks entail.

They don't just build one. You may mean they don't learn from observation of others or from their mother. They may still acquire a sense of a better trapdoor and make better trap doors by experience. I can't think of an experiment to test the theory, but it might be around qualities like "thickness" or "wind resistance" if you could make a condition of test which put the trapdoor they do un-biassed under specific stresses.

Still, even if that's true, it does not refute the point. The knowledge necessary to build the very first burrow or web, or trapdoor (which will be definitely more than good enough otherwise spiders would no longer exist) is hardcoded, not externally acquired.

Depends what you mean by complex... All creatures get born with an idea how to get food. Human babies have never seen breast or anyone sucking breast, yet they can go through the process pretty much immediately. That's a very clever movement / sensation following combination, but it's there from the beginning.

Babies are definitely hardwired to be attracted by the contrast of skin / areola on the female breast. Once they have targeted this contrast, they will do a very typical (also hardwired) "search" for the nipple: they come very close to the breast, open their mouth, do exploratory sucking via fast breathing, and quickly move their head left and right until they have "docked" on the breast. They start doing this minutes after birth (they are also hardwired to search for the breast when placed on the mother right after birth), and stop once their sensory systems are fully developed and they have learned how mom looks, how mom smells, and where mom's breast is (after 1-2 months). On my own child, I even noticed how it once mistook the snout of a teddy bear for a female breast.

The "will suck at anything" instinct is IMHO a fall-back mechanism if for some reason a female breast is not available.

Here's a source for the above claim that I found after looking this up:

During pregnancy, the nipple has become more pigmented 68 and is easy for the newborn infant to discover (Fig. 1C). We have observed that soon after birth, the areola expands and takes a bulb-like shape (Fig. 1G). The Montgomery glands also become more pronounced (Fig. 1G). The scent of areolar secretions has been linked to behavioural responses, such as head turning 69 and directional crawling in newborn infants 70. This release of the breast odour by the Montgomery glands is known to help the newborn infant find the nipple 17, 27, 69. The newborn infant recognises the scent of the mother's breast from the amniotic fluid 71, touches the breast and transmits the taste of the breast to the mouth (hand-to-breast-mouth movements) 17. This stimulates rooting and crawling movements in the newborn infant to reach the nipple. The connection between the taste of amniotic fluid and the scent of the breast from the Montgomery glands highlights a biological survival mechanism – a pathway of flavour with lifelong consequences. (Fig. 3) (17, 71-80) When knowing of this sensitive odour-dependent mechanism, it might be wise not to interfere with unfamiliar hands.[0]

simple nets for sure, but spiders can easily deal with an uncountable number of corner cases, I somehow think it's not reducible to all-too simple rules (in the 'game of life' sense) and more an interaction of several non-trivially complex systems like their various perception systems.

obviously their neural networks are limited in size and therefor complexity has to remain somewhat simple relatively to larger animals).

Many years ago when I was working IT for a public school district, I was unpacking a large number of identical HP PCs from cardboard boxes. I noticed that a large portion (it must have been half or more) of the boxes had the exact same type of spider in a nearly identical web in the exact same spot in the cardboard box. It was a small cardboard cubby taped onto the inside of the large exterior box, for storing a power cord and other small accessories. It must have been just the right shape and size, and accessible in just the right way, that this type of spider absolutely loved it.

I saw a project on GitHub some time ago where someone trained a neural net with only a single, shared weight to play a driving game.

They used a gentic algorithm to evolve the network, its connections and activation functions (per node).

It got quite good.

Perhaps not that surprising that one can encode a lot in the graph structure itself, and given how DNA is quite good at dictating complex organs, I don't see why something similar couldn't be at work for insects and mammals alike. After all, nobody taught the newborn kangaroo babies how to crawl up into the pouch of their mom either.

I kind of wonder whether certain cultural artifacts might be genetically inspired. My son, when he was young, without any prompting wanted to be an architect (like his great-grandfather whom he had never met, nor even heard anything about before this) and was obsessed with guitars (like me, although at that point, my own guitar had been in the basement for years and he had never seen me play it). This is not to say that these particular behaviors are explicitly encoded in genetics (both guitars and architecture as a discipline are much younger than evolutionary time), but rather that some intrinsic predisposition towards them exists (so, perhaps had we lived in fifteenth-century Persia, we would be oud-obsessed, to choose one posseible alternate reality).

Story time.

I'm from Western Australia and spent a lot of time in its deserts in my youth.

I have a very distinct memory of walking out among the spinifex as a child, needing to pee. Its hot, my bare feet are burning, the ground is unforgiving and I already have spinifex'ed ankles, so naturally I tread as carefully as I can, trying to avoid the sand and the spikes, only walking on the slightly less heated organic mats that surround some of the spinifex, a kind of carpet of twigs and leaves, gathered in pockets by the wind.

The natural urge is rising, and I stop paying attention and get a bit of pace, as relief must be had. I see a particularly appealing area, covered by this organic dust, and I leap over to it, get my body parts aligned, and begin the process of relief.

A few seconds into it, I feel something moving. The entire mat that I was standing on, is in fact, a field of trap doors. Maybe a hundred of them. They begin to open.

I have never levitated as hard and as fast in my life.

So my Tabula Rasa has given me this lesson: don't go into the spinifex to pee. Ever.

For example I do have a strong reaction to cockroaches till this day; a harmless insect that my mother fear. I can't even look at the beast. My cousin do not and conversely do fear spiders.

I’ve thought about differing levels of innate behaviors in different species as being somewhat akin to different sorts of programming languages. So dogs and cats are more akin to, say, Pascal¹ which provides a high level of functionality at the language level, but are limited in capability² while humans are more like C where there’s less functionality out of the box, but the ability to accomplish unique tasks is less bounded.

1. This is a theory I came up with as a high school student in the 80s so my choices of programming languages reflect that.

The respect is of other researchers who have to consume the data at a later date.

Humans use names for non human things as well and using a number doesn't imply spider anymore than anything else. Is #16 a spider or a sheep? Did anyone ever confuse Dolly for a human?

It also doesn't tell us that it's one of at least 16 data points. From the article we only know that it was the 16th spider they recorded as being present but we don't know that any of the other 15 made it into the study. The fact that you're reading something we don't know into it from the name #16 actually highlights a failing in this system for me. Surely if it matters to you then you'll be reading the study which will these details explicitly.

Thats fine, just keep your personal preferences out of my labs' white paper submissions.

"Number 16" is valuable, in that it communicates the fact that the specimen involved is one of a set of at least 16 individual data points. "Brenda" doesn't communicate anything much more than, perhaps, the researcher is bored with their work and wants to have fun instead of doing real science. Besides which, this is a human name, so is it referring to a human or a spider?

Of course, in the limit case if there were no governors after 1882 (except the current one, if any) it would just say the one in 1882 was dead, but there were, in fact, 24 or 25, depending on exactly when in 1882 the tortoise arrived (not sure on that), subsequent governors before the position was abolished with home rule which quickly transitioned into independence.

Which makes the “yet” weird, but I suppose it admits the possibility that the office might be restored before the tortoise dies, and the tortoise might not outlive the potential future governor.

Sure, the "yet" seemed to imply that one governor has taken over. There's no further information regarding the number of governors, and I refrained from speculation. All I could deduce was that the 1882 governor is dead, the current one is alive, and there is a nonnegative whole number of intervening governors (zero or more).

Very few people seem to be able to distinguish between "the largest number on record" and "the largest thing that ever happened", even if they know perfectly well that records of whatever the phenomenon is are never kept.

Black widow spiders last something like a thousand eggs, and the hatchlings murder and easy one another until only a couple survive... Who go in to live for as long as black widows live for. The average lifespan is likely quite low, however.

Imagine the life of a spider. Imagine it for forty three years. Lurking in your burrow, waiting for a snack to wander by. Getting fucked by spider boys and maybe eating them. Do trapdoor spiders eat their mates? I’m not sure. Laying eggs and watching the spiderlings go running off. Again and again for forty three years.

That just feels like a long time to be a spider.

And it was killed, who knows for how long it could have lived.

In my opinion, the logical assumption is that this spider species can't live for much more time than exactly that interval of time

The interesting point here to me is that it was not killed before. This suggests that it was able to fend off the wasps attacks for fourty years. I assume that hen died it was too weak (too old) to fight back. Another possibility is that it had moult recently and was too soft to defend itself.

Insects die soon because adult wings can't moult twice. Spiders don't have wings so they can moult indefinitely and became much much older than insects --but-- is easy to predict that (unlike jellyfishes), spiders can't live forever

We can be 100% sure of this empirically. We even could predict mathematically the life time span of each species, also if we would want it (again, in my opinion).

A neighbor of mine went from the most brilliant and kindest person I've ever met, to not recognizing his own wife at home in a short time span of few months.

The fact that he would not recognize me after talking together every week for a decade felt slightly odd.

But what broke the camel's straw was after one morning he assaulted his own wife coming back with groceries thinking she was an intruder.

Living 50 years together and not remembering her at all was awful.

Broke her and his heart too when he had to be taken to a proper elderly care facility as he was too dangerous (70+ but still very fit and strong) to his own family. Obviously, luck wanted that he was lucid when they were taking him out the house. He was aware of what was happening and why for few minutes. But when it came to say goodbye it felt like Shutter Island finale, you couldn't say whether he was now faking a few moments later or if he was doing it because aware of his condition and danger.

I wonder what it’s like living life idle 99% of the time. Do spiders get bored?

it's neat that the spider outlasted the arachnologist's career.

I wonder how long it would have lived without the wasps' interference.

Australian arachnologist Barbara York Main ... returned to the site annually, sometimes more frequently, for more than four decades.

Huge respect. Always amazed by scientists sticking with studies like that.

Because of Number 16, Main's project took far longer than she had expected. She continued to work into her late 80s, but she "began to look forward to the project's end"

Reminded me of The Onion's "Expert Wasted Entire Life Studying Anteaters":
