Question
Why is ethics taught to engineers and computer scientists at all, rather than left to philosophers?
Answer
Because the people who build a system decide what it does — so the question "could we build this?" has to be joined by "should we, and how should we shape it?"
The argument, made forcefully by Harvard's Barbara Grosz in her work on embedding ethics into computer-science teaching, is that technical training answers only half the question. A competent engineer can tell you whether a recommender, a face-recognition pipeline or a credit-scoring model is feasible. Nothing in that training tells them whether it should exist, who it will hurt, or which design choice quietly settles a moral question.
Two habits follow, and they are the actual learning goal:
- Recognition — noticing that a situation contains an ethical question in the first place. This is the hard part: most harmful designs were not chosen over an obvious alternative, they were shipped by people who never saw a decision being made. Alison Simmons frames the aim as getting used to asking "in this context, how might an ethical question arise?"
- Justification — being able to say why one answer is better, in terms someone who disagrees can engage with. "It felt wrong" does not survive a design review; "this treats users as a means only, and here is the alternative" does.
Ethics in a technical curriculum is therefore not a compliance module bolted on at the end. It is the claim that design decisions are moral decisions, so they belong in the same room as the architecture.

Question
What is the difference between a value and a norm, and how do the two relate?
Answer
A value is an idea or way of behaving held to be desirable — it is graded ("more or less good"); a norm is a rule that says what you must, may or must not actually do — it is binary and binding.
| Value (Wert) | Norm | |
|---|---|---|
| What it is | An idea, conception or behaviour regarded as important and worth striving for | A rule, standard or prescription |
| Held by | An individual, a group, an institution, a community | A community that expects compliance |
| Expressed as | good / bad / evil / neutral | required, permitted, forbidden |
| Character | Evaluative and gradual — things can be more or less good | Binary and obligatory — you comply or you don't |
| Bears on | What is desirable | An action: doing or refraining |
| Examples | Health, prosperity, environmental quality, justice, dignity, freedom, success, happiness | Human rights; "do no harm to others"; "don't be late" |
The important nuance about values: the more generalisable an idea is, the more objective the value becomes. "I like punk music" is a purely subjective preference; health, prosperity and environmental quality are values almost anyone would sign up to, which is what gives them weight in an argument.
The relation between the two is one of derivation: norms are the practical implementation of values. A value on its own tells you nothing about what to do on Tuesday morning; the norm derived from it does.
Tip: Value = adjective ("that would be good"). Norm = imperative ("you shall not"). If you can put "-er/more" in front of it, it's a value; if it splits the world into allowed and forbidden, it's a norm.
