Humility is a critical aspect of science communication, as demonstrated by recent events surrounding the United Nations' (UN) report on child mortality estimates. The UN's announcement of a historic milestone in global child mortality in March 2024, with deaths among children under 5 falling below 5 million in 2022, was a significant achievement. However, the definitive language used in the announcement masked underlying uncertainties and potential issues with the data. This highlights the importance of humility in science communication, where acknowledging the limitations of data and methodologies is crucial for maintaining trust and accuracy in scientific reporting.
The UN's projections relied heavily on modeled estimates based on historical data, with only 5% of the 2022 estimate derived from countries with actual data for that year. This lack of empirical basis raises concerns about the robustness of the estimates. Furthermore, the model failed to account for the potential temporal discontinuity caused by the COVID-19 pandemic, which could have indirectly affected child survival rates. The pandemic's impact on health services and vaccination rates, for instance, may have contributed to changes in child mortality that were not fully captured by the model.
The UN's role as a science communicator should be to provide clear, evidence-based insights while acknowledging the limitations of its methodology. By being transparent about the uncertainties and potential biases in the data, the UN can build trust with its audience and ensure that its communications are accurate and reliable. This is particularly important in global health policy, where decisions based on flawed data can have far-reaching consequences.
In conclusion, humility is a critical aspect of science communication, especially in the context of global health policy. By acknowledging the limitations of data and methodologies, scientists and communicators can ensure that their work is accurate, reliable, and trustworthy. This is essential for maintaining public confidence in scientific research and ensuring that global health policies are based on sound evidence.
