The interaction grid was meant to be a model for observation within and between each kind of individual. Adult males vs infants, children, sub-adults, adult females, and other adult males. And take that down the line for each type of individual. No there were no presumptions (just as Fukuoka had none). Just watch what happens. And yes there were implications for zoo policy--shortly after this the primates were re-organized into groups rather than being housed in individual cages, in part as a result of this study. This is Albert, the engaging silver back who started the whole thing.
