It makes sense though, think about how complex even speaking one language is, the massive dictionary of combinations of words, that even people below average intelligence, have in our heads, and the abstract reasoning we have to put them all together, and we can do this almost instantly during conversations or conversing online. That's not even to mention body language, intonation, or deeper meaning that we pick up instinctively. Like we still can't even train computers to do this shit reliably

There is no evidence that chimps drove out humans out of the trees, and it seems odd that we could defend ourselves from lions and hyenas out on the plains but not chimps? It is funny that in this IQ test the chimps beat the humans, and it puts into perspective human IQ tests (and explains why some very high IQ people are unwise and often dumb as rocks in many aspects of human behavior). The conclusion that we are not better because we can speak is laughable when we look at the modern world, you have to be seriously ungrateful to come up with that.

Is it really the memory or is it the vision that is important for the task shown at the start of the video. OK, after seeing Michael play around the by himself I can see the difference between the short term memory.

These monkeys were trained to do this. If I sit there for long enough, I would get as good I would imagine. If you look at high skill video game players, esports, speedrunners. there is a lot of instant reflex solving these puzzles their mind has to go through. I'm not fully convinced we lack this skillset at all, just that we are not very much trained for it in daily life.

I don't think this task gives us any measure of how much better a chimp is than a human... There's a great difference that comes with practice. would the chimp memorize the 9 numbers in 0.5 sec on his first day trying? Would Michael not be able to compete if he trained on this task for a long time each day?
jjcevallos12 Vor 6 Stunden
Possibly there is something different about chimpanzee’s vision as well? I noticed that I couldn’t even see all the numbers within the half a second. Could the chimps see and distinguish all 9 objects because they have less accurate vision at the center of the eye, which allows for wider focal point?

9:17 And think of it like this, if you have a group of something that can communicate, they don't need to think and have that good of short-term memory in the way of Chimps. You can have 5 different people all looking in different directions and each of them can speak to each other to tell everybody how many there are and this would be just as fast if not faster than the Chimp because the speed that each individual needs to only recognize 1 or 2 important targets is still more then enough.

Language combines thousands of years, billions of minds in to one. The ability to transfer knowledge is the backbone of human evolution.

I like to think primates thousands of years ago were problem solvers and found more ways to leave trees in spite of curiosity, not dominance. Like how in the video they repeatedly state that the chimps use short-term memory for quick responses, most likely used as an easy way out to escape danger. Whereas our ancestors typically could've taken challenges head-on, seeking to solve an underlying problem, hence our different feet with short toes and our body's build. I've also wondered where languages really took root whether in rudely name calling through hunger ravages or drawings of landscapes etched from personal tools. Nonetheless, this is all very interesting and I love to hear and see strides in the foundations of knowledge our probable numb skull ancestors ventured in.

Someone has probably already said this but the way this is presented ain't great. You have two variables that are being changed: 1) the training and 2) the species. Yadda, yadda yadda I would love to see how a human does at the task with the same amount of experience.

It might not be talking. It might be reading and writing. People who can write have much poorer memories than people who are not literate, because we can keep records instead of relying on our memories. Have the experimenters tried this experiment on pre-literate tribal people? They might be surprised by the result.

Id felt that it's hard to balance a "go with the flow; live in the moment" mindset and the planning of one's future. Interesting hypothesis.
what i would like to know, is, what is the best that a human could get at this game, with practice? i've heard of how good some chimpanzees are at this game before, but I have not yet seen a human do it, who has had a lot of practice, like the chimpanzees get.

Bullshit. It's not impossible to do the memory tests. Humans just need training that's all. The human mind is capable of anything. Curious to know why he didn't disclose how the chimps knew how to count in the first place... and why didn't he use a savant to compete with the chimp.

Primate apologist. How difficult would this game be if you, or any of your viewers, practiced this game every day for six months, and the complexity and speed correlated with accumulated success? The proposition of dropping an individual into unfamiliar territory, and comparing their inferiority to an expert in the field as an argument, makes a poor argument, even when the expert is a trained chimpanzee. Every sort of neural "hard-wiring" is possible when associated with survival, and practiced.

I’m only 2 mins in and my theory for the video: We all have 6 senses, the sixth being your sixth sense, and he rest is the obvious sight, taste and all that. If you didn’t know, if you take away one of those senses, the other get stronger, that’s why people sometimes close their eyes when eating food so their taste it 2x as better. You can test this by sitting and watching tv but close your eyes and notice how the sound from the TV has slightly changed. You can also spin around with your eyes closed and try and guess where your tv is. So I’m thinking for the rest of this video, chimpanzees have way better eye sight as they can’t speak which is basically the sense of taste.

I think the reason why ayumu is so good at the test is because he do it repeatedly, that is why ayumu had the advantage, Micheal did it for the first time that is why he loss, but overtime i think its possible for Micheal to improve.The test on humans vs chimp must have been done so long ago.
