Introduction:

The Evolutionary Games Infographic Project (EGIP) seeks to promote and improve the teaching of game theory by providing a diverse set of free graphic images for use in classrooms, on websites, and in other published work. Game theory has become an important and influential theoretical tool in economics, evolutionary biology, and political science, but most game theory teaching is aimed at more mathematically-inclined students. In initiating the EGIP, we asked the question “how can graphic design and other forms of visualization make game theory more widely accessible?”. We created these images to help teachers of game theory to provide better instruction and to help learners better understand game theory.

In the first phase of the project, we have tackled four important theoretical games that are important for understanding how cooperation evolves: the Prisoner’s Dilemma, Hawk-Dove (also known as Chicken or Snowdrift), Stag Hunt, and Ultimatum games. For each of these games we have created a set of “conceptual” and “sequence” images that explain how the games work without the use of numerical representation. In addition, we have also created a series of “example” images that illustrate realistic scenarios which might be well represented by the Prisoner’s DilemmaHawk-Dove, or Stag Hunt games. We have also produced an interactive PDF that allows learners to explore the dynamics of an archetypal Prisoner’s Dilemma “scenario”.

A User’s Guide, aimed at providing teachers and learners with guidance on how to best utilize these images, will be released during the summer of 2012.

The project has been ongoing, evolving in response to feedback we have received and experience using these images in my Evolution of Cooperation course. To follow the full progression of the project, you can access the collected EGIP blog posts that have appeared on this site.

Available infographics:

During the Fall 2011 and Spring 2012 semesters, Greg Riestenberg and I created the first infographics packages for the Prisoner’s Dilemma, Stag Hunt, Hawk-Dove, and Ultimatum games. Greg is a graduate student in Pratt’s Communications Design program, and he provided the vast majority of graphic ideas as well as all the graphic expertise and labor for the project. Below you can download full packages for each game in large/CMYK and small/RGB JPEG formats. You can use the gallery below to find the SVG file for each image.


For each game, you can download packages containing complete sets of large versions (letter-sized at 300 dpi) of these files by clicking on the icons below:

         
These “large” packages are provided in CMYK and are ideal for print applications.


For each game, you can download packages containing complete sets of small versions (600-800 pixels wide) of these files by clicking on the icons below:

         
These “small” packages are provided in RGB and are ideal for web and other screen-based applications.


If you would like to browse for a particular image, below is a gallery of all the images we have made available thus far:

 

Prisoner's Dilemma embezzlement scenario PDF download

Our latest project is an interactive PDF that allows the user to explore the Prisoner’s Dilemma through a realistic “scenario” in which two businessmen are caught embezzling funds. Using a storybook format, this PDF allows the user to play the role of one of the the embezzlers, choosing to either cooperate with his accomplice by “staying quiet” or defect on his partner-in-crime by “confessing”. By exploring the potential consequences of this choice and learning that the outcome for each embezzler depends on the choice of his accomplice, the user gains an appreciation for this archetypal Prisoner’s Dilemma scenario. You can download this PDF by clicking on the cover page to the left or on the Wikimedia page for this work. There’s also a matrix “example” graphic that was designed to work in conjunction with this interactive PDF.
