The authors address these questions by incorporating two critical dynamics, typically ignored in extant work: competition between information and over-time processes. They present results from experiments on two technologies: carbon-nanotubes and genetically modified foods. They find that factual information is of limited utility - it does not have a greater impact than other background factors, it adds little power to newly provided arguments/frames, and it is perceived in biased ways once individuals form clear initial opinions.
