I agree. In the case of fast moving policy debates, open analytical code is also important. There are also situations when government agencies like the Congressional Budget Office, the Joint Committee on Taxation, and many many others use private data sources like tax return data. In these cases, I think they should be required to release the analytical source code as well as data dictionaries that allow others to create dummy or synthesic data. They should also release detailed summary statistics when possible-- after taking differential privacy concerns into account.
