Overview
A model is a mirror of its data. When the data forgets a continent, the
mirror returns a smaller, quieter version of the world — and calls it
objective. This research brief examines AI bias and fairness through the
lens that matters most for African builders: training data.
The central argument is that bias in African contexts is primarily a story
of absence, not malfunction. The continent enters modern AI systems in
three asymmetric roles — the under-sampled subject, the extracted resource,
and the downstream consumer — and each role compounds the others.
What the full brief covers
- The representation deficit — the hard numbers behind African
under-representation in vision, language, and genomic datasets.
- An anatomy of bias — the five distinct mechanisms (representation,
measurement, label, aggregation, deployment) that introduce distortion.
- Case files — documented harms across facial recognition, large
language models, clinical diagnostics, and precision medicine.
- The extraction layer — data labour, the economics of annotation, and
the data-colonialism critique.
- The counter-movement — African-led work: participatory NLP, locally
built models, and accountability benchmarks.
- Governance & sovereignty — the continental policy picture and why
data sovereignty is a competitive moat, not a compliance task.
- A builder's stance — an eight-point playbook for shipping AI that
performs fairly in African markets.
