The Human-Centred AI Glossary
The AI Dictionary that you didn't realise you needed
Most AI glossaries explain how machines work. This one explains what humans need to know. Every term here is defined through a single lens: does this help you stay the author of your own decisions?
A
Absent User
The person affected by a decision but not present when it is made. Naming the absent user keeps systems humane and prevents harm by default.
Adaptive Intelligence
The combined strength of human judgement and machine speed working together, with humans retaining responsibility.
Agency
The capacity to shape circumstances rather than be shaped by systems, habits, or automation.
Agentic AI
AI systems that take autonomous action toward goals with limited supervision. As agency increases, human guardrails become essential.
Algorithm
A set of instructions that turns inputs into outputs. In modern systems, algorithms increasingly influence decisions once made by people.
Algorithmic Drift
The gradual transfer of judgement from humans to automated systems through defaults and convenience.
Alignment (AI Alignment / Value Alignment)
Ensuring AI systems pursue outcomes humans actually want, rather than optimising narrowly in harmful ways.
Anthropomorphism
Treating AI systems as if they think or intend, leading to misplaced trust.
Artificial General Intelligence (AGI)
A hypothetical form of AI capable of learning and reasoning across domains at or beyond human level.
Artificial Intelligence (AI)
Systems that learn patterns from data to predict, classify, or generate outputs. Powerful tools, not moral agents.
Attention (Self-Attention)
The mechanism that allows AI to weight which inputs matter most. Humans do this naturally; machines must be trained.
Attention Economy
The competition to capture and monetise human focus, often at the expense of depth or wellbeing.
Augmented Mindset
The disposition to treat AI as an extension of capability, not a replacement for judgement.
Authorship
Taking visible responsibility for decisions and meaning rather than deferring to systems.
Automation
Delegating tasks to systems that operate without continuous human input. Valuable only with accountability.
B
Bearings
Your moral and cognitive orientation when speed increases and systems accelerate.
Benchmark
A test used to compare system performance. What gets measured gets optimised.
Bias (Algorithmic Bias)
Systematic distortion caused by skewed data or assumptions.
Black Box
A system whose internal reasoning cannot be easily inspected or explained.

The quiet expansion of what systems decide without explicit permission.
C
Cadence
A steady rhythm of work and reflection that replaces urgency with progress.

Cognitive Offloading
Delegating mental effort to tools. Useful when deliberate, risky when unconscious.

Design
Conscious authorship. Choosing direction instead of accepting drift.
Design Debt
The cost accumulated when speed overrides care.
Digital Drift
The quiet surrender of time and attention to algorithmic curation.
Diffusion Model
AI that generates images by refining noise into form.
Drift
Unconscious compliance with systems or habits that decide for you.
Drift Debt
The accumulated cost of uncorrected small shortcuts.
Drift vs Design Matrix
A lens for diagnosing whether action is deliberate or default.
E
