The bias on this forum is largely American european or western. How do I know this? Language. You'd obviously get a different flavor of bias on a chinese forum. Can you imagine yourself claiming your own country to be more corrupt than another? If not then how can you imagine a prideful chinese person doing the same? Bias colors every corner of this forum just like it would color a chinese forum.
I would say I am less biased on this topic than the average person on HN. How can I say that though when bias can color my judgement on my own bias? How can anyone say such a thing due to this recursive fact?
I believe the method around this problem is not to use your own judgement to judge bias in your own judgement but to look at external factors surrounding your circumstance and use probabilistic causative connections between those external factors and possible bias to determine a persons' overall level of bias. For example, an African living in the congo will have less bias on a China vs. America debate than a chinese person, an icelander will be less biased than a new yorker for the same debate. The external factor in the previous examples is race and location.
So for me I come from a more different background. I am chinese and american. I hold no nationalistic pride for either country and I could see my self living in either country if need be. It's apples and oranges to me, literally. Racially though, I'm chinese so from circumstance my bias would be equal to an chinese born american but less than an american born white guy or an asian born mongoloid. Overall I'm probably more biased than the african.
In short, I am less biased than most people on this forum because of my background. So a neutral venue would be like people who talk about this stuff but are mostly from like singapore.
