RESUMO
Drawing on Metzger's dual-processing model of credibility assessment, this study examines how individuals with varying topical knowledge (laypersons vs experts) assess the credibility of information on novel foods. Online focus group discussions reveal that both groups share similar motivations for assessing the credibility of information on novel foods (e.g. personal relevance and concerns about the impact of unverified information on others). However, they differ in the barriers they encounter during the assessment of information credibility. Both groups employ analytical (e.g. evaluating content quality) and intuitive methods (e.g. looking at source credibility) to assess the credibility of novel food-related information. However, they differ in the cues used for credibility assessment. Laypersons tend to rely on superficial heuristics (e.g. social endorsement cues or surface features), whereas experts rely more on content features and scientific knowledge to evaluate information credibility. Theoretical and practical implications are discussed.
RESUMO
Despite the recent approval of cultured meat products in Singapore, the understanding of public perceptions towards this novel food technology remains limited. Utilizing attitude formation theory and the mental models approach, this study compares the mental models of the general public and experts regarding their risk and benefit perceptions of cultured meat. Through four online focus group discussions with 40 participants, we found convergences in the mental models of experts and the general public concerning perceived individual- and societal-level benefits of cultured meat (e.g., health benefits and food security) as well as their perceived individual-level risks of cultured meat (e.g., potential health issues and affordability). However, divergences in understanding societal-level risks were noted; the public expressed concerns about the challenges of cultured meat to religious and racial dietary customs, while experts highlighted potential investment uncertainties due to unclear consumer acceptance of cultured meat. Theoretical and practical implications are discussed.
