Eric Ray and Glenn Langenburg delve deep into the data from the White Box and Black Box studies regarding the exclusion decision. Ulery, Hicklin, Roberts, and Buscaglia publish on their exclusion data revealing a strong correlation between exclusion accuracy and the presence of a core or delta in both impressions. Glenn and Eric also look at how minutiae count and latent quality affect exclusion accuracy and then discuss the utility of the exclusion decision itself. Interesting stuff.
