Who checks their work
Natalie Brooks — author
Natalie Brooks writes with an editorial focus on interdisciplinary research, scientific reviews, evidence synthesis and studies that combine findings produced through different research methods. At CAB Direct, Natalie covers research reviews, emerging evidence and interdisciplinary studies. Her articles explain where results from different research traditions can reasonably be considered together and where differences in populations, methods or measured outcomes prevent direct comparison. Each of her articles names her as author with a stated role. Findings included in reviews and evidence syntheses are checked against traceable sources, primary results remain separate from broader interpretations, and corrections are dated and stay visible in the article.
