An expert-curated global database of online newspaper articles on spiders and spider bites

In the Internet era, the digital architecture that keeps us connected and informed may collaterally amplify the spread of misinformation and falsehood. The magnitude of this problem is gaining global relevance, as evidence accumulates that misinformation interferes with democratic processes and undermines collective responses to environmental and health crises. Therefore, understanding how misinformation generates and spreads is becoming a pressing scientific, societal, and political challenge. Advances in this area are delayed because high-resolution data on coherent information systems are difficult and time-consuming to acquire at global scales. We collated a high-resolution database of online newspaper articles on spider-human interactions. Spiders are widely feared animals that frequently appear in the spotlight of the global press. Our database covers a global scale (5,348 news articles from 81 countries and 40 languages) while providing an expert-based assessment of the content and quality of each news article. Here, we first show that the quality of news on spiders is exceedingly poor—47% of articles contained different types of error and 43% were sensationalistic—and we consolidate a quantitative understanding of the relationship between article quality and different news-level features. Among other factors, the consultancy of spider experts, but not doctors and other professionals, decrease sensationalism. Next, we show that the flow of spider-related information occurs within a highly interconnected global network and provide evidence that sensationalism, along with other predictors including numbers of spider species and internet users in a country, are key factors underlying the spread of information. Our results improve understanding of the drivers of (mis)information across broad-scale networks. They also represent a starting point to formulate recommendations for improving journalism quality. In the specific case of spiders, a more accurate media framing would translate into measurable benefits, limiting resource waste and mitigating human-wildlife conflicts and the prevalence of widespread arachnophobic sentiments.
