One pressing challenge posed by artificial intelligence (AI) is that its use may weaken democratic accountability for national security decisions, including the resort to force. Military and intelligence decisions are highly consequential, but paradoxically can be the most difficult for legislatures and courts to oversee because they are often classified. To ensure that executive actors adhere to the public law values of accountability, rationality, and legality, we also rely on additional, less predictable tools such as leaks, technology companies, and pressure from foreign allies. Even with these additional tools, many decry the “black box” nature of national security decision-making and the polity’s ability to constrain the Executive when it makes poor policy choices or acts unlawfully.

The rise of AI systems to enable national security decision-making – or even make autonomous decisions – will deepen this critique, because it is difficult to understand how AI algorithms reach their conclusions. Some refer to these algorithms as “black boxes,” because programmers and users generally cannot access the algorithms’ internal processes or the basis for their predictions. Military and intelligence agencies in some democracies have already begun to use AI. But how can we be confident that these AI systems comport with our laws and values? Will national security officials retain the power to override algorithmic decisions and, if so, when and how? The widespread use of AI will render national security choices inside democracies even more opaque – not only to the public, but also to those on the receiving end of the government’s national security actions, allies, legislative overseers, and even the officials making the security decisions. This “double black box” raises critical challenges for democratic accountability and for the existing international legal regime that regulates states’ use of force.

The talk will define and explore the “double black box” phenomenon, analyse its costs and benefits, and identifies ways that policymakers, military and intelligence officials, and lawyers in democratic states such as the United States and Australia can reap the advantages of advanced technologies without surrendering their rule of law values.
