If we are talking about charity evaluations then reliability can be estimated directly so this is no longer a predictable error.
Hmm. This made me wonder whether the paper’s results depends on the decision-maker being uncertain about which options have been estimated reliably vs. unreliably. It seems possible that the effect could disappear if the reliability of my estimates varies but I know that the variance of my value estimate for option 1 is v_1, the one for option 2 v_2 etc. (even if the v_i vary a lot). (I don’t have time to check the paper or get clear on this I’m afraid.)
Is this what you were trying to say here?
