The diverse challenges that are faced during the COVID-19 pandemic demand a range of responses and require an innovative approach. However, the key success factor in any pandemic policy relies on behavior. Declarations and actions do not always overlap, and thus, predicting future behavior solely on the basis of self-reported measures seem to be ineffective (Ohme et al. in Anthropological Approaches to Understanding Consumption Patterns and Consumer Behavior. IGI Global, Hershey, pp. 427–448, 2020). This paper intends to highlight what do Portuguese really feel about the pandemic by using the “COVID-19 Fever” project data collected and analyzed with the iCode Smart Test in Portugal. Thanks to Consumer Neuroscience and Advanced Analytics, a new perspective goes beyond rational verbatims to investigate real deep non-conscious convictions that people may not even be fully aware of, which cannot be covered by traditional opinion surveys. By providing evidence from Portugal during the lockdown, this study offers unique data to analyze the influence of culture on attitudes and valuable insights into both practitioners and researchers.
