The Frame Problem (FP) is a puzzle in philosophy of mind, articulated by the Stanford Encyclopedia of Philosophy as follows: "How do we account for our apparent ability to make decisions on the basis only of what is relevant to an ongoing situation without having explicitly to consider all that is not relevant?" In this work, we focus on the causal variant of the FP, the Causal Frame Problem (CFP). We first introduce a notion called Potential Level (PL). We substantiate the claim that PL may bear on how time is encoded in the mind. Using PL, we propose an inference framework, PLIF, which permits a boundedly-rational approach to the CFP, formally articulated at the algorithmic level. We show that PLIF is consistent with several findings in the causal judgment literature, and that PL and PLIF make a number of predictions, some of which are supported by existing findings.
