Yes, this is a pretty fuzzy 'science' topic - i.e. measuring public opinion. Looking at something a bit more quantitative would make sense. For example, infectious disease epidemiology is kind of mid-way between hard and soft. Looking at Covid transmission and outcomes relative to vaccination and testing, for example, might fit the bill. There's a good deal of uncertainty in the data (lack of reporting, widespread differences in prevalence of testing, efficiency of vaccines relative to different Covid strains, etc.) but ultimately it revolves around a hard science measurement (was person X infected with virus Y).
