Methodology question: I am trying to figure out how to measure the degree to which a risk-related problem has become a public issue. The metric needs to be easily analyzed, accessible, quantitative, and stable over at least five years (from 2015 to 2020) and have high face validity. The measurement should be robust – it does not have to be particularly refined or capable of resolving small differences.
The application for this metric is that I am developing a project that has to do with factors (such as Peter Sandeman’s “outrage”) that determine which risk-related (environmental, health, sustainability) issues become public issues over time. I need a way to measure outcomes and compare them against predictions.
Social media is the most obvious approach. One metric would be Google hits, which is convenient, free, and cumulative, and which almost certainly will be around in five years in roughly the present form without too much bias from algorithm changes introduced over the period. On the other hand, I am concerned about Twitter because I’m not sure it will be as stable a platform over the time period and I’m not sure how much people tweet about issues as opposed to people and events. Newspaper inches in a journal of record (such as the New York Times), which used to be an old standby, might be completely obsolete by 2020.
I would be grateful for practical ideas.
