A new research paper challenges the notion that prediction bottlenecks in models like Mamba can inherently discover causal structure. The study, conducted by Aman Chadha, found that while early experiments suggested this capability, a more rigorous falsification benchmark revealed that simpler methods like linear bottlenecks and even classical techniques such as PCMCI and Granger causality performed as well or better. The paper highlights that the perceived advantage of prediction bottlenecks in causal discovery is largely due to sample-size confounds and non-standard intervention schemes, rather than an intrinsic property of the architecture.
