 Another thing that some take to be strange about geometric averaging is that it sometimes will aggregate identical credences to a different group credence. For instance, we might all have credence .7 that it is raining, but our group credence might be .9. Easwaran et al. (2016) argue, though, that this often makes sense when updating on the credences of others—their confidence should make us more confident (see also Christensen  2009).[4]
