One thing I found striking will reading for, preparing for, and writing my general exams is
how difficult it is to effectively measure risk awareness and concern. The most standard ways of doing this are, at least as far as I can tell, to:
1) ask people to rate their perceptions of risk via questionnaires (e.g., how risky do you think a nuclear accident is? Or, how risky do you think a nuclear accident is in relationship to a car accident?);
2) use "decision problems" along the lines that Tversky and Khaneman (1981) used in their seminal "The Framing of Decisions and the Psychology of Choice" article (e.g., what would you choose: X number of certain deaths or Y number of possible deaths? Morbid, I know); or
3) Do some sort of cost benefit analysis, where you ask people what is their willingness to pay (WTP) to avoid a certain risk or how much of a certain risk are they willing to accept (WTA) (e.g, how much money would you pay to not have a hazardous waste facility sited near you? Or, how much risk is too much risk for you to continue smoking?)
A couple interesting things here: First, all of these approaches really rely on self-reported estimates of risk tolerance/avoidance/concern. Questionnaires and WTP/WTA rely entirely on people saying how risky they think something is and/or their estimate of what they would pay to avoid a risk or how much risk they are wiling to accept. As such, these approaches are fraught with bias--does someone really know how much they are wiling to pay, when push comes to shove, to avoid having a hazardous waste facility sited next to them? I am pretty darn sure (and plenty of research shows) some people tend to over-report their WTP and others under-estimate what they would pay to avoid a risk. Similarly, if you ask me how risk I think a nuclear accident is, I might say one thing before an accident like Fukishima and something quite different immediately following a disaster of this sort. While it could be argued that the questionnaire is accurately capturing my risk perception at a given moment, this enormous subjectivity raises some interesting questions about the accuracy of this approach (as well as highlights the inherent subjectivity and, as I say, "subject to change-ivity") for measuring risk concern and awareness. Even decision problems, which force people to select between two options and compare what risk they would be more willing to take, and thus seem to have a bit more grit to them, don't really tell us what people would do in a real life risk decision-making situation. This is all particularly problematic given that research in psychology, cognitive science, and other human sciences shows that people's perceptions of risks are heavily influenced by a range of heuristics such as the "availability heuristic" (people tend to draw on information that is readily available, rather than doing a thorough analysis, when making decisions about complex information. Hence, why nuclear accidents seem so much more risky to many people after an accident like Fukishima) and the "proportionality effect" (people tend to prefer saving 100 lives out of 1000 rather than 200 people out of 2 million). Since we tend to fall back on these funny heuristics in evaluating complex information and risks, and our conception of, response to, and reactions regarding risk are largely subconscious, context dependent, and psychologically complex, self reported measurements of risk awareness and concern seem particularly fraught with hazard. And this is just in trying to measure individual perspectives on risk!
Now, let's take this question of how to measure risk perception and concern to the collective level.
How do we measure a group's or a community's risk awareness and concern? Do we just aggregate the responses of all of the individuals into some group risk awareness and concern metric? Do we average across community willingness to pay to avoid a risk? Or do we do something different, such as have a group dialogue about risk and see where people come out at?
This last option is particularly interesting, since
I have a pretty strong hunch that people's concern and awareness of a given risk might change noticeably as a result of their participation in a well structured dialogue about a particular risk, such as local climate change risk or flooding risk. Has any specific research on this been done? If not, we should do this, Michal. Get a group of people together, measure their individual perceptions of a risk, have them dialogue about the risk (with some information), then see where they come out at in their risk perception/concern. This is kind of like deliberative polling, but the whole idea is to analyze whether perceptions of risk can be directly influenced by communicative rationality/collaborative rationality.
Also and related, I think it would be really interesting to do some sort of a decision problem, along the lines of the Tversky and Khaneman model, with groups. What if we did a decision problem with individuals, and then asked them what they would do as a group, giving the group time to dialogue about whether they would choose option A or option B. Then we could contrast whether there is any difference (individual choices as contrasted with group choices) to see if communicative rationality/collaborative rationality influences risk awareness/concern/choices.
Ok, that's my big brain dump, it may not be nonsensical, but at least it's a start.
Assuming I pass my exams tomorrow, I'm super excited to keep adding to this blog of thoughts. If I don't pass, I might by in Idaho by this time next week becoming a ski and mountain biking bum.
