I think there is somewhere a topic like this, but I could not find it.. anyway, does someone knows how a specializated scientist appears? In my actually campaign, I have only production/construction, sensors and fire control and power and propulsion scientists and after 70 years, I never ever got scientists on defense, energy weapons, biology and logistic fields which I have a desperate need!!! they continue to appear only in the first group of research; I thought they may be influenced by the type of government, but I changed it different times from fascism, to pax utopia, but nothing has changed.
