Computational Social Science Seminar Posted

Last Friday I gave a presentation on the challenges of strategic intelligence, and how Agent-Based Modeling fits within and can improve current analytic tradecraft. The slides have now been added to the website, and can be found on the Papers and Presentations page. The slides are somewhat sparse and are mostly talking points. There is a layer in the file that contains speakers notes that contain more information and bibliographic credit where graphics, quotes, and images were taken from other sources. Likewise, the abstract for the presentation can be seen on the Department of Computational Social Science website here.

Rock-Paper-Scissors and Arms Races Part 6

Previous posts had examined the replicator equation as the basis of agent behavior in an arms race defined by a game of rock-paper-scissors (RPS). This post begins a follow-on examination regarding the use of best-response as an alternative behavior or strategy on the part of competing agents. In some ways, best-response may be unrealistic with respect to how agents can adapt, especially if they are capable of making large jumps or changes to strategies in short-periods of time that are not reflective of real-world organizations. However, in other ways, the strategy is quite realistic for social actors because it affords them opportunities to revive dead or eliminated strategies when suitable while the biologically based replicator loses them forever once extinct.

The Use and Abuse of Models in International Security

Some days just appear to have a theme that constantly nags or colors everything that happens. It happens that yesterday was one of those days for me. I’m in the process of finishing up a project and I need to complete a book chapter on the validation of ABM based analysis for national security analysis. Importantly, the issue is less about the validation of the models themselves, and more concerned with whether or not analysts can use models for responsible inferences in support of decisionmaking. It also happened that the director of the Krasnow Institute where I work posted this on his own blog, and I came across this older piece in on the Wired website regarding some DARPA work that I’m familiar with. To add just a small piece more, a former government senior executive came to speak to my department yesterday about the challenges of ‘wicked problems’ in government, particularly in the design, development, and employment of new technologies and the difficulty of getting to work with the social structure of the government (building a new widget was rarely the difficult part).
