Public confidence in research is important for scientific results to achieve societal impact. Swedish surveys suggest consistent but differing levels of confidence in different research areas. Thus, certain research-related factors can be assumed to have a decisive influence on confidence levels. This focus-group study explores the role of different narratives in shaping public confidence in research. Findings include four themes with potential to increase or decrease public confidence: Person, Process, Product and Presentation. The results offer insights as to how public confidence in research is formed and may give researchers agency in promoting confidence through their communication activities.
