Moses demonstrated a lot of qualities that are linked to D-style behavior in the D-I-S-C Framework. These include decisiveness and daring.
Moses also displayed the classical D-I-S-C Framework recognition of an absence of Patience in the D-style mindset.
Moses smashed the tablets of stone to pieces when he realized that the Israelites had created idols.
Most notably, Moses struck the rock to produce water in a bout of frustration at the disgusting behavior of the Israelites. He was instructed to “speak to the rock”. That bit of impatience actually cost him his place in the Promised Land.
We should also recall that he killed the Egyptian who was abusing one of his countrymen.
Moses seemed to have a relatively short fuse. That is in keeping with D-I-S-C Framework analysis of classic D-style behavior.
