There are tons of sources if you just type anything in Google, but here is just a snack as an example: octopuses recognize individual people: https://pubmed.ncbi.nlm.nih.gov/20563906/ https://pubmed.ncbi.nlm.nih.gov/20563906/ There are also articles about how they use tools, estimate intent, etc. Here is one about how they use deception: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440998/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3440998/ This entails that they have a mental model of what others think of them, which ranks very high on the evaluation of animal consciousness.

Tons of insects use deception tactics and you would not suggest they're as "intelligent as a cat", let alone have a mental model. Hell, there are deceptive plants. See this about European lady's slipper orchids - https://link.springer.com/article/10.1007/s00114-009-0611-0 https://link.springer.com/article/10.1007/s00114-009-0611-0 It's tempting to explain away all behavior with consciousness, but it's not necessarily accurate.

  > Tons of insects use deception tactics No, read better: "[...] in a specific social context amenable to cheating 39 per cent of the time, while it was never employed in other social contexts" It's completely different from what simple insects do, here it entails that they understand the specific social context. Now you could reply to me that eusocial insects do that a lot, basing their behavior on cues like pheromones etc. To which I'd say: yes exactly, and that's why eusocial insects have the largest brains among insects. Cephalopod can solve amazingly difficult puzzles (unlike social insects) AND also have social skills. Which gives a big boost to how they score on intelligence evaluation. Moreover, one can argue that using pheromones is much easier than deducing the social context solely upon visual cues, because in insects pheromones already encode very specific meanings and are linked to hard-coded behaviors. Octupuses' social skills also a reason to how well they bond and interact with their human caregivers.

    > what simple insects do It should be clearly inferred if I'm invoking deception tactics that I'm not talking about "simple insects". But that is still a large number, out of 925,000 species. > To which I'd say: yes exactly, and that's why eusocial insects have the largest brains among insects. The connection you're supposed to make here is they still don't exhibit the level of consciousness and intelligence you had been purporting. I don't see why octopi should be any different.

      > they still don't exhibit the level of consciousness and intelligence you had been purporting But they do, on social tasks, only the insects use much simpler cues, whereas octopuses, humans, etc, use social cues that they have to painstakingly extract from raw data, like visual or auditory data.
