What's interesting is that there is a high correlation between themepark/game/casual and sandbox/world/hardcore. Without much reason. The same is true in politics. There is a high correlation between pro-nuclear energy, contra-abortion and small government. Without much reason it seems.
The reason is evolution. In the 10.000 tribes scenario I described a few days ago, the best way to solve complicated problems was try & error. That's why humans tend towards one side of a dualism and band together. The opinion becomes an ideology when people have a strong initial reaction towards something.
Remember that NYT article ?
We could save billions in health care costs and make healthier food cheaper if we taxed nutritionally weak foods.
I'm not giving you the link, because I don't want you to read it. Fact is that most of you have a strong initial emotional reaction once you read this. Only after that initial emotional reaction will you start to try to find arguments for or against it.
In the 10.000 tribes scenario this is a powerful evolutionary mechanic. The tribe becomes ideological about the most important questions and eventually splits. Since the tribe must not split into too many parts, groups converge. Thus, the guy who believes in global warming suddenly also believes in higher taxes. What is important to realize is that this convergence is (mostly) arbitrary, completely subtle and unconscious.
Of course, nowadays we cannot realistically split, let alone wage planet-destroying world wars. So we need to compromise eternally. Modern societies are all about this eternal compromising.
If you want to reach beyond your "ape instincts" as the lovely ideologist Gevlon so fittingly calls it, you need to try to ignore the first initial reaction. You need to look at the arguments first and only then form your opinion. Of course, you will fail; you're human. All you can do is be aware of this effect.
