Weaponisation of artificial intelligence (AI) presents one of the greatest ethical and technological challenges in the 21st century and has been described as the third revolution in warfare, after the invention of gunpowder and nuclear weapons. Despite the vital importance of this development for modern society, legal and ethical practices, and technological turning point, there is little systematic study of public opinion on this critical issue. This interdisciplinary project addresses this gap. Our objective is to analyse what factors determine public attitudes towards the use of fully autonomous weapons. To do this, we put the public at the center of the policy debate, starting with youth engagement in political and decision-making processes.
