Counterintuitively, wealthier countries tend to be more vaccine skeptical than poorer countries. One possible explanation—the Online Accessibility hypothesis—posits that internet access facilitates the spread of antivaccine misinformation, particularly for those lower in scientific and medical expert trust. Another explanation—the Out of Sight hypothesis—is that some citizens in richer countries fail to consider the risks of vaccine-preventable diseases because they are rarely experienced directly. Merging country-level data with nationally representative survey data (N = 149,014) from 144 countries, we find evidence for the Online Accessibility hypothesis. These findings are robust to alternate measures of wealth and modeling strategies.

互联网接入如何推动全球疫苗怀疑论

与直觉相反，富裕国家往往比贫穷国家更怀疑疫苗。一种可能的解释——在线可访问性假设——认为互联网访问促进了反疫苗错误信息的传播，特别是对于那些科学和医学专家信任度较低的人。另一种解释——看不见的假设——是富裕国家的一些公民没有考虑疫苗可预防疾病的风险，因为他们很少直接经历。将来自 144 个国家的国家级数据与具有全国代表性的调查数据 (N = 149,014) 合并，我们发现了在线可访问性假设的证据。这些发现对于替代财富测量和建模策略是稳健的。
