The assertion is that people have a tendency to see things as zero sum even when they are not. Do you see why giving an example that is zero sum in some sense and not in another doesn't impact the validity of that claim?
Yes, but why is it new and useful information to know that people might have a zero-sum bias when one is aware one does not have an objective way to decide whether one should act to correct it in any given situation - i.e. should preference be given to the individual or the group, or the group or groups?
The concept "fight zero-sum bias" is just another way to say "think positive", "always look on the bright side of life", "be optimistic". It's nothing new, except the word "fight" makes this version war-like.
Unfortunately, humans are not naturally good Bayesianisms. We're not even naturally good traditional rationalists. We have a lot of cognitive biases. When we talk on LW about fighting we mean fighting against those biases so we can reason more accurately. Don't confusion fighting with some sort of deep ideological meaning. In this sense, fighting means something like grappling with oneself. The only ones we are fighting with is our imperfect reasoning algorithms that evolved to handle a very different environment.
I find the use of the word "fight" disconcerting. It's a messy word. The way we think is a mechanical process. If there is a right way to think it has the potential to be explained. The word "fight", which carries emotional and irrational connotations, need never be invoked. I don't think this is a trivial point.
It's possible that a zero-sum scenario may appear positive-sum once the zero-sum bias has been corrected, but that is merely a short term illusion because the fate of the individual is also tied to that of the group.
Also I disagree with the idea human psychology has evolved to "think the worst" of each other. Can it be proved we have a zero-sum bias? In many situations it would be more helpful to counter positive-sum bias - in Ponzi schemes, for example, not everyone can be a winner.
Yes, but why is it new and useful information to know that people might have a zero-sum bias when one is aware one does not have an objective way to decide whether one should act to correct it in any given situation - i.e. should preference be given to the individual or the group, or the group or groups?
Well, in general, being more aware of biases makes one more able to compensate for them if one has some set of goals. Many LWers are utilitarians for example in which case the group, indeed, the largest group, is all that's relevant. In that context, thi...
This is the first part of a mini-sequence of posts on zero-sum bias and the role that it plays in our world today.
One of the most pernicious of all human biases is zero-sum bias. A situation involving a collection of entities is zero-sum if one entity's gain is another's loss, whereas a situation is positive-sum if the entities involved can each achieve the best possible outcome by cooperating with one another. Zero-sum bias is the tendency to systematically assume that positive-sum situations are zero-sum situations. This bias is arguably the major obstacle to a Pareto-efficient society. As such, it's very important that we work to overcome this bias (both in ourselves and in broader society).
Here I'll place this bias in context and speculate on its origin.
Where this bias comes from
It's always a little risky to engage in speculation about human evolution. We know so little about our ancestral environment that our mental images of it might be totally wrong. Nevertheless, the predictions of evolutionary speculation sometimes agree with empirical results, so it's not to be dismissed entirely. Also, the human mind has an easier time comprehending and remembering information when the information is embedded in a narrative, so that speculative stories can play a useful cognitive role even when wrong.
Anatomically modern humans appear to have emerged 200,000 years ago. In the context of human history, economic growth is a relatively recent discovery, only beginning in earnest several thousand years ago. The idea that it was possible to create wealth was probably foreign to our ancestors. In The Bottom Billion, former director of Development Research at the World bank speculates on the motivation of rebels in the poorest and slowest growing countries in the world who start civil wars (despite the fact that there's a high chance of being killed as a rebel and the fact that civil wars are usually damaging to the countries involved)
Neither the developed world nor the countries that Collier has in mind are genuinely good proxies to our ancestral environment, but like the people in the countries that Collier has in mind, our ancestors lived in contexts in which growth of resources was not happening. In such a context, the way that people acquire more resources for themselves is by taking other people's resources away. The ancient humans who survived and reproduced most successfully were those who had an intuitive sense that one entity's gain of resources can only come at the price of another entity's loss of resources. Iterate this story over thousands of generations of humans and you get modern humans with genetic disposition toward zero-sum thinking. This is where we come from.
For nearly all modern humans, the utility of zero-sum bias has lapsed. We now have very abundant evidence that the pie can grow bigger and that win-win opportunities abound. Both as individuals and as representatives of groups, modern humans have a tendency to fight over existing resources when they could be doing just as well or better by creating new resources that benefit others. Modern humans have an unprecedented opportunity to create a world of lasting prosperity. We should do our best to make the most of this opportunity by overcoming zero-sum bias.
