Part 01
01 / Foundation

Ethics is not a
brake.

In the tech world, ethics has a bad reputation. It is seen as a disruption to progress, the thing that slows teams down and complicates products. That is wrong. Ethical AI is better AI: more precise, more reliable, fairer.

When systems harm people, there is a cost. Trust, money, human dignity. A facial recognition system that recognises darker skin less well is not a "value-free" tool. It is a system that discriminates. The question is not whether AI has values. It always does. The question is: Whose values? And who gets to decide?

Core principle

Every AI system encodes values. In the dataset, in the design, in the decisions of the teams that build it. Ethics in AI is not an add-on. It is the question of which values get built in, and who controls that.

01

Algorithmic fairness

An algorithm is not neutral just because it is a machine. It reflects the data it was trained on and the decisions of the people who selected that data. Fairness is measurable, but measurement is a choice too.

02

Algorithmic bias

Bias arises when systems systematically disadvantage certain groups, often unintentionally, but with real consequences. It can be hidden in the training data, in the model design, in the way success is defined.

03

Accountability

When an AI system causes harm: who is responsible? The developer? The company? The user? This question is often unclear, and that is no accident. Lack of clarity protects those who hold power.

04

Transparency & conscience

Transparency does not mean making everything public, but making it possible to explain how decisions come about. Conscience means asking these questions before you ship. Not afterwards.

Part 02
02 / Bias in practice

This is what bias
looks like.

Bias is not an abstract term. It shows up in concrete systems with real effects on real people. Choose a scenario and see how systems treat different groups differently.

03 / Who carries the burden?

Distributing
responsibility.

When an AI system harms people, the same thing often happens: everyone points at someone else. Developers at the data. Companies at the users. Governments at the technology. This diffusion of responsibility is structural, and politically convenient.

Responsibility is not a binary question of "guilty" or "not guilty". It is a system of different actors carrying different kinds of responsibility.

Actor Type of responsibility Typical excuse Accountability
Developers Technical decisions: architecture, data, metrics "I just write code" High
Companies Deployment, product decisions, business model "We have terms and conditions" High
Users Using the tool, passing on outputs "I only use what is on offer" Medium
Governments Regulation, standards, enforcement "Technology moves too fast" Medium
Data suppliers Quality and representativeness of the data "We only collected it" Medium
Affected groups Formally: none, but 100% of the consequences none No power
Observation

The group that is most affected typically has the least control and say. That is no accident. It is the structure of power in tech systems.

Algorithms do not discriminate
because machines are evil,
but because people were.

04 / Principles

What ethical AI
means.

There are many frameworks. Many of them are PR. These six principles are a practical foundation: not a cure, but an honest start.

01 / Fairness

Not equally wrong for everyone

Fairness does not mean everyone gets the same. It means nobody is systematically treated worse, especially not groups that are already marginalised.

02 / Transparency

Explainable, not infallible

Systems must be explainable: to those affected, to developers and to regulators. "The model decided" is not an explanation. It is a refusal of responsibility.

03 / Accountability

Someone has to answer for it

When a system causes harm, there must be a named, reachable person or body responsible. Not a structure that spreads responsibility until it disappears.

04 / Conscience

Before you deploy

Not afterwards. Not when the press reports on it. Conscience means asking the uncomfortable questions: Who does this harm? Whose data? Who profits, and at whose expense?

05 / Participation

Involve those affected

The people most affected must have the biggest say. Not as a "user test" but as structural co-determination. This is the hardest principle.

06 / Do no harm

The minimum standard

At the very least. No system that predictably causes harm should be deployed, however profitable. That sounds obvious. It is not.

Part 05
05 / Exercises

No right
answers. Almost.

Ethics is not a multiple-choice exam, but some answers are still better than others. These exercises train the critical thinking you need to question AI systems, whether you build them, use them or regulate them.

01 Spotting bias: who is missing from the dataset? Analysis

Task: A company develops an AI system for HR decisions. It was trained on 10 years of historical hiring data. During that period 87% of the company's staff were men. The system now mostly recommends men for leadership roles.

Choose the statement that best describes the problem:

The system works correctly: it reflects historical reality, and reality is objective.
The problem lies with the applicants: more women should apply.
The system reinforces historical disadvantage: historical data reflects past discrimination, not qualifications.
AI systems cannot be biased: algorithms are mathematically neutral.
02 Assigning responsibility: who is to blame? Position
Scenario

A hospital uses an AI system that assesses patient risk. The system systematically assigns Black women patients lower risk scores than white women patients with identical health conditions, because it was trained on historical cost data and Black patients in the US had on average received less healthcare (not because they were healthier, but because they had less access). Result: Black women patients are less often referred for intensive treatment.

In your view, who bears the most responsibility, and why? Write your answer in 3 to 5 sentences.

Your assessment:
03 Prioritising ethical principles: what weighs more? Reflection

Task: Put these ethical principles in your personal order of priority: drag and drop them into the order you think is right. There is no objectively correct answer, but you will be asked to explain your decision.

⠿1Do no harm: no system that predictably causes harm
⠿2Fairness: no systematic disadvantage for groups
⠿3Transparency: decisions must be traceable
⠿4Accountability: always someone named as responsible
⠿5Participation: those affected have a say
⠿6Privacy: people control their own data
Why did you prioritise this way?
04 The dilemma: security vs. freedom Position
Dilemma

A city is considering an AI system for crime prevention. It analyses public cameras and behaviour patterns to flag "suspicious persons". It has a 73% hit rate, but a 27% false-positive rate, and these false alarms disproportionately affect people of colour and queer people.

According to the manufacturer, the system would raise the clearance rate by 18%.

Several people argue differently. Choose the position most compatible with ethical use of AI:

Person A: "A 73% hit rate is good enough. The alternative is more crime. Collateral damage is acceptable."
Person B: "The system should be used, but only with human review of every flag."
Person C: "A system with a 27% false-positive rate that disproportionately hits marginalised groups is not a security solution. It is a discrimination system. It should not be used until systematic bias has been eliminated."
Person D: "Technology is value-neutral: police officers make the decisions, not the system."
05 Designing transparency: explain it to the person affected Design
Situation

Mariam, 34, is classified by the job centre's AI system as having "low employability". Her benefits are then cut by 40%. She receives no letter explaining why, only a standard form saying: "Your assessment is based on an automated decision."

Write an explanation for Mariam as it should be: understandable, honest, without legalese. What did the system decide? On what basis? What can she do?

Remember: transparency means the person can actually understand it , not that something has been explained in legal terms.

Your explanation for Mariam:
06 The conscience audit: would you build it? Reflection

Last exercise. This one is personal. Imagine you are hired as an AI developer or AI decision-maker on one of the following projects. You are well paid. Which would you take on, and which not? Briefly explain why.

Project A

A system that pre-sorts asylum applications and creates risk profiles. Goal: cut processing time. Known: the training data reflects caseworkers' prejudices.

Project B

An AI for queer young people offering anonymous counselling and resources in countries where homosexuality is illegal. Risk: privacy and state surveillance.

Project C

A recommendation algorithm for news articles that deliberately prioritises emotionally charged content because it increases time on site. The company says: "We only deliver what people want."

Project D

An audit tool that examines existing AI systems for bias and produces reports for regulators. Low profit. Big impact.

Your answer:
Ethics in AI is not a question
of technology.
It is a question of power.

Who decides what gets optimised? Who bears the consequences? Who has a voice? These are the real questions behind every AI system.
