Another thing I personally respect (although alas no longer a local do can only take their word for it!) is the open self-critique and using that to spur themselves on to better interpretation, broadening narratives and intentionally seeking out where their own gaps might be.
There is a good breakdown of how democracy developed in the UK, the role political parties have played, the rise of trade unions, how public protests have been used to fight for civil rights, and the creation of key institutions such as the NHS.
