Very interesting results. There's a massive overlap between the current generation of AI research/development and neuroscience, and it's fitting that by so desperately trying to make a computer intelligent we are unexpectedly learning more about how our own brains work.

> we are unexpectedly learning

Many expected this, decades ago. But, also, many claimed that neural networks have nothing to do with the brain. I think we're slowly inching towards and understanding that we're the result of some fundamentals of information organization, and those fundamentals are realized in biology, rather than come from it. Those fundamentals are now showing themselves in silicon.

This is a poor bit of research. The question "is it more cat-like?" Is leading as it specifically instructs the participant to look for cat-like features. The experimenters neglect to establish the null hypothesis.

They made stimuli to be either cat-like or sheep-like, for instance, and asked them to pick the more cat-like. It wasn’t between cat and nothing.

> If brain activations are insensitive to subtle adversarial attacks, we would expect people to choose each picture 50% of the time on average. However, we found that the choice rate—which we refer to as the perceptual bias—was reliably above chance for a wide variety of perturbed picture pairs

Ok, but the article doesn’t say what was the actual rate?

Why do they assume that 50% choose cat and 50% choose truck? Or did I miss the part where they show the participants an untampered version of the image to create a baseline.

I mean, cats are small and cute, trucks are big and stinky.

And wouldn't the subject of the image also make the participants possibly lean to one of the answers? Flowers in a vase go well with a cat (both can be found in an apartment, for example). If the image would show the ISS, would more people tend to pick "truck", for example?

In case you were wondering what N was, their first experiment involved 16 undergrads psych students and the second experiment involved 12. https://link.springer.com/article/10.3758/BF03206939 Edit: I believe this linked survey is not the subject of the OP.

Am I the only one who finds this to be a sort of wasteful experiment for one of the supposed top research labs in the country to be publishing in such a (supposedly) prestigious journal? The findings aren't super shocking although they would be interesting enough if they had managed to collect a large enough sample.

Instead they barely grasp at straws and come to an obviously inflated conclusion that neural nets and human brains are similar in some way because of this (which _certainly_ isn't something they arrive at or even experiment for, in my opinion).

I don't see how this is surprising. The noise pattern in the first figure looks cat-like: I can see the ears, the head, the paws, the front half of the body… Having that “seemingly random pattern” to trace over would probably let me sketch a cat, something I can't normally do without a reference. (Though, the face is muddled and in the wrong place – almost like it's a cat collage – so I might only get the outline of…

Maybe my brain's just odd... but I don't see the cat-like figure in the noise. I just see noise. There are a few edges, but nothing really cat-like to my mind. My subconscious pattern recognition for faces and such has always been weak, fwiw.
