Developmental changes in perceived moral standing of robots
We live in an age where robots are increasingly present in the social and moral world. Here, we explore how children and adults think about the mental lives and moral standing of robots. In Experiment 1 (N = 116), we found that children granted humans and robots with more mental life and vulnerability to harm than an anthropomorphized control (i.e., a toy bear). In Experiment 2 (N = 157), we found that, relative to children, adults ascribed less mental life and vulnerability to harm to robots. In Experiment 3 (N = 152), we modified our experiment to be within-subjects and measured beliefs concerning moral standing. Though younger children again appeared willing to assign mental capacities — particularly those related to experience (e.g., being capable of experiencing hunger) — to robots, older children and adults did so to a lesser degree. This diminished attribution of mental life tracked with diminished ratings of robot moral standing. This informs ongoing debates concerning emerging attitudes about artificial life
Doing the right thing for the right reason: Evaluating artificial moral cognition by probing cost insensitivity
Is it possible to evaluate the moral cognition of complex artificial agents?
In this work, we take a look at one aspect of morality: `doing the right thing
for the right reasons.' We propose a behavior-based analysis of artificial
moral cognition which could also be applied to humans to facilitate
like-for-like comparison. Morally-motivated behavior should persist despite
mounting cost; by measuring an agent's sensitivity to this cost, we gain deeper
insight into underlying motivations. We apply this evaluation to a particular
set of deep reinforcement learning agents, trained by memory-based
meta-reinforcement learning. Our results indicate that agents trained with a
reward function that includes other-regarding preferences perform helping
behavior in a way that is less sensitive to increasing cost than agents trained
with more self-interested preferences.Comment: 11 pages, 3 figure
Immutable morality: Even God could not change some moral facts
The idea that morality depends on God is a widely held belief. This belief entails that the moral “facts” could be otherwise because, in principle, God could change them. Yet, some moral propositions seem so obviously true (e.g., the immorality of killing someone just for pleasure) that it is hard to imagine how they could be otherwise. In two experiments, we investigated people’s intuitions about the immutability of moral facts. Participants judged whether it was even possible, or possible for God, to change moral, logical, and physical facts. In both experiments, people judged that altering some moral facts was impossible—not even God could turn morally wrong acts into morally right acts. Strikingly, people thought that God could make physically impossible and logically impossible events occur. These results demonstrate the strength of people’s metaethical commitments and shed light on the nature of morality and its centrality to thinking and reasoning
