No, Jowy has had at least intermittent research visibility.
C&D primarily relies on using three things:
Demographic graphs (via espionage): A team's individual power, crop yield, population, manufacturing, GNP, etc. etc. The most reliable data, but comes at a cost of requiring sufficient EPs against your opponent.
The Demographics Screen: Aggregate data on all opponents. Separating out individual teams can be difficult.
Score changes: Sometimes things can be inferred merely by score changes. For example, population in this game is worth about 2.5-3 points, so score changes of +/- that amount are almost certainly from population growth or the whip.
