In the Community Balance Patch, social policies have been changed dramatically with the reforming of every policy tree. The 9 social branches are divided into 3 specific eras: Tradition, Progress (Liberty), and Authority (Honor) unlock in the Ancient Era; Fealty (Piety), Statecraft (Patronage), and Artistry (Aesthetics) unlock in the Medieval Era; and Industry (Commerce), Imperialism (Exploration), and Rationalism unlock in the Industrial Era. You also earn cumulative benefits for adopting multiple policies from the same tree. Finally, some World Wonders are now linked to different trees and some have been unlinked (For example, the Pyramids were linked to the Liberty tree, but now the Forbidden Palace has taken its place). Wonders linked to policy trees can only be built if the relevant tree has been completed and you have researched the necessary technology.
Each tier of policies can be unlocked by getting 6 other Policies or advancing 2 Eras. To unlock access to Ideologies, you must unlock 18 Social Policies (and at least have reached the Industrial Era) or reach the Atomic Era, whichever comes first.
The previous system was needing 3 Finishers for Ideologies.
