This week, I’m recommending Helen Pearson’s Aeon essay, “How to Assemble Science.”
Pearson explains why a single new study—even one receiving widespread media attention—rarely provides enough evidence for a major decision. Reliable knowledge emerges when researchers systematically compare many studies, evaluate their quality and determine what the overall evidence supports.
This principle is highly relevant to African business and public policy. Decisions about agricultural inputs, climate adaptation, food safety, healthcare and emerging technologies should not rest on one headline, consultant’s claim or isolated success story.
Local and lived knowledge must also be considered, particularly where international research may not reflect African conditions.
AI could make evidence reviews faster, but speed cannot replace transparency, verification and sound human judgment. Before adopting a new idea, the better question is not simply, “Is there a study?” but, “What does the full body of credible evidence show?”

Humanity produces a staggering amount of new knowledge every day. The question is how to make sense of it all
