  Warnings and risk communication: Guidance for healthcare
  facilities, edited by Michael S. Wogalter, David M. DeJoy, Kenneth
  R. Laughery

  SUMMARY: Questions regarding how best to communicate
  warnings
  and risk information, whether such communications are
  likely to be effective, and what factors influence the
  communication process are of importance to today’s
  society. Stimulated by the tremendous growth in
  litigation on product liability and associated
  personal injury, research into communicating warnings
  effectively has developed rapidly over the last few
  years. This book addresses the major issues in theory,
  research and applications of warnings and risk
  communication, bringing together leading international
  authorities in the field.

  Part 1. Introduction
  1 Overview (K.R. Laughery, A. Hammond)
  2 Organizing theoretical framework: a consolidated
  communication-human information processing (C-HIP) model
  (M.S. Wogalter, D.M. DeJoy, K.R. Laughery

  Part 2. Methods/techniques
  3 Intermediate processing stages: methodological
  considerations
  for research on warnings (S.L. Young, D.R. Lovvoll)
  4 Methodological techniques for evaluating behavioral
  intentions
  and compliance (M.S. Wogalter, T.A. Dingus)

  Part 3. Research on warnings: stages of the model
  5 Source (E.P. Cox III)
  6 Channel (M.B. Mazis, L.A. Morris)
  7 Attention capture and maintenance (M.S. Wogalter,
  S.D. Leonard)
  8 Comprehension and memory (S.D. Leonard, H.Otani,
  M.S. Wogalter)
  9 Attitude and beliefs (D.M. DeJoy)
  10 Motivation (D.M. DeJoy)
  11 Behaviour (N.C. Silver, C.C Braun)

  Part 4. Practical issues of warning design
  12 Standards and government regulations in the USA
  (B.L. Collins)
  13 Practical considerations regarding the design and evaluation
  of product warnings (J.P. Frantz, T.P. Rhoades, M.R. Lehto)

  Part 5. Forensics
  14 T he law relating to warnings (M.S. Madden)
  15 The expert witness (K.R. Laughery)

  There is an excellent book by Mark Monmonier titled “Cartographies of Danger.” There is some excellent discussion throughout on the presentation of hazard (which threatens life or property) as opposed to risk (the probability of a threat being realized), which may be helpful to you.

  Hillary “Holly” Hosmer has presented a paper on visualizing qualitative risk factors in risk analysis. The only quantitative display she covers is the Cost/Loss (lives, dollars, objects).
  NIST-sponsored conference paper: Visualizing Risks: Icons for Information Attack Scenarios, Hilary H. Hosmer Data Security, Inc. PDF NIST.GOV.

  At first glance, it might appear to be an exercise in “chart junk”. However, given the use tree concepts and tree/network diagrams in risk and fault analysis, there is a need to lift the cognitive level from tree-of-words to tree-of-concepts. It’s in that (unstated) context that she searchs for expressive Icons that can be used as “selective” elements in Network Diagrams of risk relationships. This is outside the realm of chart/table I.D. data-graphics, but still within the realm of I.A. and on the edges of Bertins larger classification scheme. I don’t know if she’s had research funding for the next, quantitative, step, which is what the questioner was directly requesting. Chris might ask her directly, if she doesn’t reply to my answer.

  Full Disclosure — You’ll find my name in the Acknowledgements, near another name familiar to all readers of this forum. Back when I was researching in Risk Analysis, E.T. only had the first book out and we were still worrying about how to compute the probabilities and measures; how to present it was not yet a concern for most in the field.

  Searches on Google, Google Scholar, and PubMed reveal that most current evidence indicates beauty recognition is an evolutionary trait that reduces risk in mate selection.
  Aharon, et al, published this study in Neuron in 2001: Beautiful Faces Have Variable Reward Value: fMRI and Behavioral Evidence. From the abstract:

  In this study, discrete categories of beautiful faces are shown to have differing reward values and to differentially activate reward circuitry in human subjects. In particular, young heterosexual males rate pictures of beautiful males and females as attractive, but exert effort via a keypress procedure only to view pictures of attractive females. Functional magnetic resonance imaging at 3 T shows that passive viewing of beautiful female faces activates reward circuitry, in particular the nucleus accumbens. An extended set of subcortical and paralimbic reward regions also appear to follow aspects of the keypress rather than the rating procedures, suggesting that reward circuitry function does not include aesthetic assessment.

  Some additional work on the attractiveness problem done by some German students is available at their Beauty Check site.

  Anatomically, the nucleus accumbens is deep in the brain, near the brain stem. It is an old part of the brain in evolutionary terms and far removed from the prefrontal cortex, the area of the brain commonly associated with risk assessment and other “executive” functions. The prefrontal cortex is new in evolutionary terms and doesn’t fully mature in humans until 25 years of age. Thus this risk assessment may be highly formalized in the mature mind, automated, and not interfered with by conscious thought.

  I am also exploring ways of visualizing risk and cost variables as an aid in decision making and problem solving. This would capture the voting from various individuals and present a composite visualization. I think the veritable 2 x 2 matrix (or 3 x 3) may be useful for this. I’d be interested in comments/examples from others.

  Here’s a few references:

  +Plus Magazine has an excellent discussion about how the way risk is framed can influence decision-making: Understanding uncertainty: 2845 ways of spinning risk.

  A useful review article, “Visualizing uncertainty about the future,” has just been published in Science [DOI: 10.1126/science.1191181].

  Abstract:

  We are all faced with uncertainty about the future, but we can get the measure of some uncertainties in
  terms of probabilities. Probabilities are notoriously difficult to communicate effectively to lay audiences, and in this
  review we examine current practice for communicating uncertainties visually, using examples drawn from sport,
  weather, climate, health, economics, and politics. Despite the burgeoning interest in infographics, there is limited
  experimental evidence on how different types of visualizations are processed and understood, although the
  effectiveness of some graphics clearly depends on the relative numeracy of an audience. Fortunately, it is increasingly
  easy to present data in the form of interactive visualizations and in multiple types of representation that can be
  adjusted to user needs and capabilities. Nonetheless, communicating deeper uncertainties resulting from incomplete or
  disputed knowledge–or from essential indeterminacy about the future–remains a challenge.

  The article itself is paywalled, but the interesting supplementary text and interactive
  graphics are freely available. The movies are hosted at the authors’ web site, understandinguncertainty.org.

  The 2011 Wisconsin Crash Calendar

  This is a “pure” data visualization, in that the data are the graphic. You can learn more about the project and download
  the 2011 Wisconsin Crash Calendar here: http://www.ghsa.org/html/resources/showcase/wi1.html
  and here: http://wisconsinsafetydataportal.org/index.cfm/wi-crash-calendar/

  The linked version is graphical and does not display the number of actual crashes, although that is a display option. The
  data can be recalculated for one or more counties or agencies. Another version uses the same categories without the
  property damage crashes, which provides an interesting comparison. A Crash Calendar using preliminary 2012 data will
  available soon.

  My larger goal is to “webize” this to create an interactive visualization that includes choropleth maps.

  I would be very interested in comments or suggestions.
