You make your choice before you get the actual inventions and effects. Basically... when you make your choice a 'flag' is set. Then later on, an 'invention' is triggered which gives you the effects of your decision which you made earlier. I know a lot of people have mentioned this before with complaint that they cannot see what the consequences of their choices are, but I quite like the way that it is kind of less gamey. What I mean is, subscribing to an ideology or system or whatever didn't have clear effects until that system, or whatever, got underway and going. Makes it more accurate for me, plus this sort of thing encourages the player to read and maybe learn something that they didn't know before??
With regards to the effects of those two inventions (there are more inventions like this found in '...db/tech/...'), here are the effects:
Choosing Jominian Attitude:
command = { type = max_elan which = infantry value = 20 }
command = { type = max_elan which = cavalry value = 20 }
command = { type = max_elan which = dragoon value = 20 }
command = { type = supplyconsumption which = infantry value = 2 }
command = { type = supplyconsumption which = cavalry value = 6 }
command = { type = supplyconsumption which = dragoon value = 4 }
Choosing Clausewitzian Theory:
command = { type = max_organization which = infantry value = 5 }
command = { type = max_organization which = cavalry value = 5 }
command = { type = max_organization which = dragoon value = 5 }
command = { type = supplyconsumption which = infantry value = 2 }
command = { type = supplyconsumption which = cavalry value = 6 }
command = { type = supplyconsumption which = dragoon value = 4 }
You get two events each for the following choices (I've combined the effects, but you can find the events in '...db/events/political_events.txt', id range 22016-22019):
Choosing Aristocracy:
command = { type = pop_militancy which = capitalists value = -5 }
command = { type = plurality value = -5 }
command = { type = capitalist_bonus value = -50 }
command = { type = diplomatic_efficiency value = 20 }
command = { type = capacity_cost_mod value = 20 }
Choosing Meritocracy:
command = { type = pop_militancy which = aristocrats value = -5 }
command = { type = plurality value = 5 }
command = { type = aristocrat_bonus value = -50 }
command = { type = diplomatic_efficiency value = -20 }
command = { type = capacity_cost_mod value = -20 }
command = { type = plurality value = 5 }
