I would caution readers against taking Barak's assertions at face value. Many of them, including some of the underlying factual assertions, are flat-out wrong; and the analytical approach is fundamentally flawed. Ian. I have backed up my statements with pointers, either direct or nearly so, to

Dimitri, Of course we're discussing multiwinner systems: systems that elect k-of-n people to a board, where k>1. As you note, when k=n the election is uncontested so there is no need for any voting system. In the Burlington election discussed, k=1 and n=3. That's about the simplest situation you

I am very happy to see SPI adopt a voting system designed for proportional representation. However I do feel obligated to correct a simple incorrect statement, namely that STV, a proportional representation system built upon IRV, is in some sense best-of-breed. STV in fact exhibits a variety of ve
