Niskanen Center — program-note: AI policy addressed ad hoc through individual fellows (Samuel Hammond on AI and institutions, Jennifer Pahlka on AI in government). Policy departments: Climate, Criminal Justice, Immigration, Social Policy, State Capacity, Government Affairs, Legal.

Note: The source confirms that Samuel Hammond and Jennifer Pahlka are both Senior Fellows at Niskanen Center, and confirms the existence of most policy departments mentioned (Climate, Criminal Justice, Immigration, Social Policy, State Capacity, Government Affairs, Legal). However, the source does not explicitly state that AI policy is 'addressed ad hoc through individual fellows' or specify their focus areas as 'AI and institutions' and 'AI in government.' The source lists them as Senior Fellows but provides no information about their specific policy portfolios or whether AI policy is handled ad hoc. Additionally, the source lists more departments than claimed (Communications, Development, Human Resources are also present), though these may not be 'policy departments' in the strict sense. The claim about AI policy focus areas is unverifiable from this source.
