I disagree, that HF user list is biased by definition.
Statistical bias is the systematic tendency in which the methods used to gather data and generate statistics (eg. having a large group of North Americans submit ranking lists) present a skewed depiction of reality (eg. having North American players ranked above non-North American players).
This is a fact-based argument, as the majority of the voters in that subforum who created that list were/are North American. Of course, biased North American voters will often throw in a token Russian or Swede high up their ratings, to appear neutral. That is a common tactic. Some may even be unaware of their own bias, since this can manifest itself in subtle ways.
The net result of a board process is the same, you get guys like Malkin rated low and some North American players rated higher than they should be.
The way to remove this bias is to adjust for the confounding variable of nationality in one’s voting panel. Otherwise, one will simply continue to produce biased lists.
