What do people need
from science communication?

Dear Pandemic invited readers to send questions to a team of scientists. By combining AI topic modeling with researchers’ interpretation, this study traced how their information needs changed over a year.

The central lesson: readers wanted science they could use in everyday decisions—and their questions changed with the news, vaccine rollout, and family life.

Questions followed events

Interest in viral variants peaked in January and July 2021, alongside news attention to Alpha and Delta.

Vaccine questions evolved

The focus moved from development to safety, then dosing, and finally how to behave after vaccination.

Everyday life mattered

Questions about family and children rose around winter holidays and summer, when people were making plans.

How to read this study

The researchers used a topic model to identify patterns in English-language questions, then interpreted those patterns as 25 topics within six themes. Figure 2 tracks daily average topic probabilities with a generalized additive model, a smooth curve through changing values. The shaded band shows uncertainty around this fitted trend; it does not capture uncertainty in the topic model itself. Each observed day contributes equally to the curve.

These are questions from people who chose to engage with Dear Pandemic, not a representative survey of the public. Timing suggests how information needs related to events; it does not establish that an event caused a change.

The topic counts and associated words shown here correspond to Table 1. The interactive curves are reconstructed from the study’s public supplements; they are not the original figure image.
