Xunzi on “obsession” and modern cognitive bias: the same diagnosis of irrationality?

I study psychology, and this term we covered heuristics and biases: anchoring, availability, confirmation bias, all the ways judgement goes systematically wrong. In the same month I read the chapter of the Xunzi usually translated "Dispelling Obsession" or "Undoing Fixation", and I could not stop comparing them.

Xunzi says the common problem of people is that they are fixated on one corner and miss the larger pattern. Desires, aversions, the beginning of a thing, its end, what is far, what is near, what is broad, what is shallow, the ancient, the present: any of these can block the mind when it attends to one at the expense of the other. His examples are wonderful. Someone walking at night sees a rock lying down and takes it for a crouching tiger, or sees a standing tree and takes it for a man following him. A drunk person tries to jump a wide ditch thinking it is a narrow gutter.

His cure is for the mind to be empty, unified and still (xu, yi, jing): able to take in new things without what it already holds getting in the way, able to keep several things in view without one crowding out another, and able to think without being driven by dreams and agitation.

My question: is this the same diagnosis as modern bias research, in a different vocabulary? Or is Xunzi talking about something different, a failure of character or cultivation, where psychologists see a failure of cognitive machinery? And does it matter for the cure?

    The cure is where they differ most, I think. For Xunzi, a clear mind is not something you achieve alone by noticing your biases. It comes through learning, teachers and ritual, through long practice under good models. Human nature, for him, tends toward disorder unless shaped. Modern debiasing usually means individual techniques, checklists, considering the opposite. Xunzi would say a checklist is a tiny ritual, and that you need a whole life of them.

    From the perception side, the rock and tiger example is almost exactly how predictive processing describes illusion. In the dark, with weak sensory evidence, prior expectations dominate, and a fearful prior produces a tiger. Xunzi's "stillness" sounds to me like reducing the weight of agitated priors. So I'd say yes, there is real overlap at the perceptual end. Where I'd doubt the overlap is at the level of whole doctrines.

    Priya's last sentence points to the part that I think has no modern counterpart. In the same chapter Xunzi diagnoses whole schools as obsessed. Mozi, he says, was blinded by utility and did not understand cultural refinement; Zhuangzi was blinded by Heaven and did not understand human beings. And so on through the rival thinkers of his day.

    That is not a heuristic misfiring. It is a whole framework seeing one real value so vividly that it cannot see the others. Bias research measures individual errors against a known right answer. Xunzi is diagnosing intellectual partiality where the right answer is a balance. I think that is a different and very important idea.

    Thank you, all three. So there is overlap at the bottom (Priya's tiger) and a real difference at the top (Yuting's obsessed schools), and the cure differs too (Pei-shan's ritual). I think what I really learned is that Xunzi's notion of irrationality is broader than ours. For him, you can be perfectly logical and still obsessed.
