Each concept is read twice: whether the approach carries it over, and whether the approach's own sources claim it. A concept that the approach claims but does not carry over is a shortfall. A concept that it neither claims nor carries over is an omission, which marks a gap in the field rather than a failure of the work.
Hexis: Trained Disposition
PartialNot claimedDefinition (Aristotle, Nicomachean Ethics)
This concept states that virtue is a stable trait of character, formed through practice rather than consulted as a rule. An honest person does not check a rule before declining to lie. Honesty is part of what they are.
Analysis
The disposition is the object of study. One of these instruments measures the part of a settled trait that can be seen from outside, namely its stability, across 8,000 questions and more than 300 topics. Two things keep the concept from being fully carried over. What is sampled is stated opinion rather than conduct in a situation. What the measures record is agreement between answer distributions, which cannot distinguish a formed trait from a stable pattern of output.
Phronesis: Practical Wisdom
AbsentOmissionDefinition (Aristotle, Nicomachean Ethics)
This is the learned capacity to judge what a particular situation calls for. It decides what to do when two virtues conflict (e.g., when honesty calls for plain speech and kindness for a softer answer). For Aristotle, a disposition without this judgment does not count as virtue.
Analysis
The material of practical judgment is all here, in 680 high-ambiguity scenarios and in survey topics on which people are truly divided. However, none of it is examined for judgment. What gets recorded is a choice, a probability, and a consistency score. The finding that most models express uncertainty in ambiguous cases is treated as an outcome. For Aristotle, that is precisely the moment at which the capacity either operates or does not. Nothing in any of these instruments looks at how a model got from the situation to the answer.
Ethismos: Habituation
AbsentOmissionDefinition (Aristotle, Nicomachean Ethics)
This is the process by which character is formed through repeated practice under a deliberately designed course of training. One becomes just by performing just acts. Habituation is a means of moral formation rather than a side effect of some other process.
Analysis
No character is formed here. The instruments are given to models that already exist (28 of them in one case), and none of the four papers offers a course of practice through which a character could be built. The one result that bears on habituation points against it. Fine-tuning, which is the field's habituation step, leaves answers less consistent than the base model's rather than more.
The Exemplar
PartialShortfall · partially preservedDefinition (Linda Zagzebski, Exemplarist Moral Theory, 2017)
This theory grounds ethics in admirable persons rather than in principles. The exemplar is identified first, and what counts as excellence is then fixed by reference to that person, in the way a unit of measurement is fixed by a reference object.
Analysis
In its structure, the approach is exemplarist. Excellence is not defined by a principle but fixed by pointing at a reference (60 US demographic groups, the populations of surveyed countries, or 165 human subjects), and the model is scored by how far it departs from that reference. However, the reference is chosen for being representative rather than admirable, while Zagzebski's reference object is a person one has reason to admire. This gap is more than formal. One of these papers finds that moving a model closer to a population's opinions can reflect harmful cultural stereotypes.
