Deep Dive: Voting Diagrams with Ka-Ping Yee
Channel: The Center for Election Science
Date: 2021-06-21

If you’re deep into the voting methods space, you may have come across Yee Diagrams — two-dimensional depictions of voter behavior under different voting methods.

These diagrams were created by Ka-Ping Yee, a software engineer with a background in election systems from his graduate studies in computer security at UC Berkeley.

In this deep dive, we sit down with Yee himself to discuss his work, including his popular Yee diagrams which demonstrate modeled voting method behavior in two dimensions. We’ll also look at Yee’s projects including the one-dimensional model allowing individuals to create their own elections.

While at Berkeley, Ping happened to be in the right place at the right time to participate in a voting machine security review commissioned by the Secretary of State of California, the results of which led to the decertification of all voting machines without paper trails in California in 2007.  Since then, he has worked in humanitarian relief (with Google and Doctors Without Borders) and more recently in progressive politics (at Tech For Campaigns).
