The Interference Gap: Comparing Retrieval Bounds in Human Memory and RAG Systems
Dongxin Guo, Jikun Wu, Siu-Ming Yiu
How do retrieval bounds compare between human episodic memory and Retrieval-Augmented Generation (RAG) systems under semantic interference? We present a unified signal detection th…

Bias by Necessity: Impossibility Theorems for Sequential Processing with Convergent AI and Human Validation
Jikun Wu, Dongxin Guo, Siu-Ming Yiu
Are certain cognitive biases mathematically inevitable consequences of sequential information processing? We prove that primacy effects, anchoring, and order-dependence are archite…

When Can Human-AI Teams Outperform Individuals? Tight Bounds with Impossibility Guarantees
Dongxin Guo, Jikun Wu, Siu-Ming Yiu
Human-AI teams fail to outperform their best member in 70% of studies, yet no theory specifies when complementarity is achievable. We derive tight bounds for the broad class of con…
