With Espionage ideas, and the Espionage-Administrative idea(adm), and the espionage-defensive idea(mil), and the administrative-defensive idea(adm), you get -0.40 corruption in total.
If you're a huge nation going for WC, you're gonna have +0.8 from territories, which is counteracted by paying fullly to root out corruption. If you're constantly at war to keep overextention high, you're gonna have a constant +0.4 or so corruption from overextention, leaving you with at least +0.2 corruption. This means you need to be ahead of time in admin or dip to actually reduce corruption.
Is it then worth it to pick espionage, and maybe even defensive for the policy?
You could pick ADM and DEF early
