Yup. Even ignoring the lack of randomization, there’s another issue with the hungry judges paper that should have raised some eyebrows.

They fit a model using both the case order (1st, 2nd, 3rd, etc) and the time elapsed. Either is significantly related to the case’s outcome, but when both are included, the rank explains away the time elapsed. This is obviously not compatible with increasing hunger/decreasing blood sugar, since those should depend on wall-time.
