Risk and Regulation: Frames,
Topics and Trust
Susanna Hornig Priest, Ph.D., and
Ted Greenhalgh
University of Nevada, Las Vegas
Two projects
South Carolina panel study; 75 individuals
over three years (NSEC at U of SC)
Experimental work on frames, topics and
trust (NER w/John Besley)
Panel study
Low awareness, but qualitative baseline
interviews showed some context for nano
– Not dissimilar to scientists’ perceptions
– More concern with regulation
Idea of a “template” for technology – even
with no familiarity, people have
expectations for risks and benefits
Concerns over “social risks” greater, and
rising, compared to health/environment
Goals of Experimental Study
Determine whether news framing (defined
“conservatively”) really matters

–
Pilot study implicates mention of regulation
Longitudinal study points to ELSI salience
Resonates with other studies, e.g. focus groups
Explore whether people “lump” nano
applications together
Evaluate the contributions of prior attitudes
The “F” Word: Framing
What we call things (labeling; e.g., Lakoff)
– Common scapegoat for controversy (Frankenfoods,
therapeutic cloning), but what evidence?
Partial truths and information effects (Entman?)
– What goes in and what not; intention?
– Classic persuasion theory suggests effects won’t last
How news practices shape stories (Tuchman)
– Beat reporting; “discovering” the story
– Narrative emphasis effect, not content effect
Study Design
Four nano news stories:
– Electronics, food processing, drug development, solar
energy applications
Four manipulations of story paragraph order:
– Benefits, physical risks, regulatory status, “social risks”
privileged
Undergrad student subjects (41) each read one
story within each application
– 16 conditions systematically rotated
Pre-tested attitudes; post-tested reactions
Preliminary Conclusions
Subtle framing effects exist but depend on topic,
treatment
– Perceived R/B ratios are higher for regulation, “social
risk” frames than benefit, physical risk frames (onetailed p = .105 for effects on society; .026 on self)
– Taking DV’s separately, most effects n.s. (except food)
– Nevertheless finding is interesting given limited nature
of manipulation (paragraph order only)
Topic much more important (no evidence of
“lumping”); some interaction w/frame
Preexisting trust factors also very important (but
not other attitudes tested)
Implications?
“Expanded vocabulary of risk”
– Controlling physical hazards is not the only
issue of public concern
Trust is crucial to attitudes toward tech
– Not likely a short-term effect of news frames
People make application distinctions, not
mindless generalizations
– Even undergraduates reading 4 stories in a row!
