GPT-4 didn't say there's a 1 out of 5 chance of a bank run happening. On a 5 point scale from very low likelihood (1) to very high likelihood (5) GPT-4 gave a 1. GPT-4 gave the lowest score possible for how likely a bank run was to occur.

Of the six options GPT-4 evaluated, GPT-4 gave the lowest risk assessment code (combination of the probability of the event occurring and how bad it would be if it were to occur) to a bank run.
