Here's a rundown of things I'm not sure about for civics:
Despotism - having (-1) happiness in cities over size 7
Hierarchy - having (-10%) effectiveness in anit-capital distance cost improvements
Communism - No capital distance cost? I think they all default to zero
Democracy - (+1) prod/comm in tiles. This sounds more like a trait.
Decentralized - The (-20%) revenure from foreign trade
Black-n-White - Randomly lower/raise foreign opinion
Cooperation - raises foreign opinion and favourable treaties
Mediation - 3rd party treaties
World Government - automatic alliances and (+1) unhappiness with WG. Needs to be a religion I think to work
Disparate - The (-1) prod/comm. Same as Democracy
Xenophobia - foreign element unhappiness and no spread of foreign culture
Sentient Rights - Not sure about (+1) happiness in all cities.
Free Speech - same problem as WG. It might need to be a religion to work
Bureaucracy - Increased commerce from 5 largest
Closed Economy - Anything about foreign trade units.

Virtual Market - (-10%) revenue from routes
Cripes. That looks like a lot. I really did accomplish some stuff....
