Brain-Score is a prominent and an essential benchmark for AI models. But why do these models have highly low behavior score even though they reach ceiling for neural score?
If an AI model which has a perfect neural as well as behavior scores, then will that model is a model of consciousness?

Why is "antitrust" doomed to fail?
Because "collusion" is not an action, it's a state.
Why is "regulation" powerless?
Because "malice" is not an intention, it's an emergence.
Why is "human morality" so powerless?
Because the physics never morality.

AI can now read words from image, different from contrastive learning where image token are learned with text tokens but rather now AI takes the image and reads the text. Definitely something for subitizing, peripheral vision and crowding studies in AI perceptual science.

when ppl say 'I didn't think about the color of the ball', did they
(1) create a full, perceptual-like mental image and then forget (or encode) the color, or
(2) really just not think of the color to begin with?
(these options showed up decades ago, but weren't studied empirically)

"Non-commitment in mental imagery is distinct from perceptual inattention, and supports hierarchical scene construction"

This paper shows that you can predict actual purchase intent (90% accuracy) by asking an off-the-shelf LLM to impersonate a customer with a demographic profile, giving it a product image & having it give its impressions, which another AI rates.
No fine-tuning or training & beats classic ML methods.
