Differences in trust and fear among respondents regarding the use of DNA in mock scenarios (Box 1). The scale presents increasing trust on the left and decreasing trust (increasing fear) on the right. 5-point Likert scale questions [Strongly Agree (SA) to Strongly Disagree (SD)] were calculated as Σ/Ν (“Trust” questions weighted 0 for each SA response, 1 for each Agree, 2 for each Neither, 3 for each Disagree, and 4 for each SD; “Fear” questions weighted 0 for each SD response, 1 for each Disagree, 2 for each Neither, 3 for each Agree, and 4 for each SA).
