Dorst et al. (2021) put forward a deference principle called Total Trust, and characterise it in terms of accuracy: an agent totally trusts an expert iff they expect the expert to be more accurate than them. This note gives a new proof of their result using a global defnition of accuracy due to Konek (Forthcoming), rather than the local one used in the original. This allows for a simpler, direct proof of the global characterisation result.
