THE CONCEPT OF THE HUMAN IN THE CRITIQUE OF
AUTONOMOUS WEAPONS
Kevin Jon Heller*
ABSTRACT
The idea that using killer robots in armed conflict is unacceptable because they
are not human is at the heart of nearly every critique of autonomous weapons. Some
of those critiques are deontological, such as the claim that the decision to use lethal
force requires a combatant to suffer psychologically and risk sacrifice, which is
impossible for machines. Other critiques are consequentialist, such as the claim
that autonomous weapons will never be able to comply with international
humanitarian law (IHL) because machines lack human understanding and the
ability to feel compassion.
This article challenges anthropocentric critiques of AWS. Such critiques, whether
deontological or consequentialist, are uniformly based on a very specific concept
of the human who goes to war: namely, someone who perceives the world
accurately, understands rationally, is impervious to negative emotions, and reliably
translates thought into action. That idealized individual, however, does not exist;
decades of psychological research make clear that cognitive and social biases,
negative emotions, and physiological limitations profoundly distort human
decision-making particularly when humans find themselves in dangerous and
uncertain situations like combat. Given those flaws, and in light of rapid
improvement in sensor and AI technology, it is only a matter of time until
autonomous weapons are able to comply with IHL better than human soldiers ever
have or ever will.
