Instant Runoff Voting (IRV) and racial minorities

Warren Smith at the Center for Range Voting analyzed the minority representation in Australia, a country that has used IRV for decades. Here is an excerpt, there is an entire webpage with charts and even pictures showing that Australia is electing caucasions only with IRV.

Instant Runoff Voting (IRV) and racial minorities

It has sometimes been stated (falsely) by IRV-propagandists, that IRV helps minorities. But in fact, the available evidence indicates it hurts them.

[Skip to conclusion] [About the (unrelated?) fact IRV favors "extremists"]

To see this, we shall compare minority representation in federal IRV-elected and plurality-elected seats versus the minority percentages in the population at large, in the top IRV-using country (Australia) and the top two plurality-using countries (USA & UK) in years 2005-2008. We find, e.g, that there are zero racial-minority IRV seatholders...

...So given this, we suggest to you that based on the data that we have, and until any evidence comes along to the contrary, you should conclude that IRV disfavors racial minorities.
