Origin of preference

The results of most studies about origin of preference tend to bias towards biological origin. This doesn't necessarily mean that people behind the studies are not neutral. Most of the successfully identified origin are biological because good research design on identifying biological origin may yield conclusive evidences, where as identification of non-biological origin requires complicated disentanglement of confounding factors. The difficulty is worse when the non-biological origin is too abstract or not well defined such as "free will", culture or even seemingly simple things such as personality, comfortability, etc.

It is worth to mention of an approach to identify the origin of preference, which is using evolutionary psychology framework. It basically states that natural selection makes surviving humans have a certain kind of preference. For such case, it's arguable that origin of that particular preference is biological since evolution mostly change biological trait. On the other hand, from evolution perspective, the reason that a particular biological trait is more likely to survive, is how fit the trait with environment. In short, there is a component of nurtural origin too.

btw, evolution approach is usable to analyze complex preferences (such as why some people tolerate more uncertainty or what kind of condition induced toleration of uncertainty) when we don't know the cause-effect relationship of origin of preference.

At the end, it doesn't really make sense to make distinction between natural (biological) origin of preference and nurtural (non-biological) origin of preference is not that important since they influence each other. Exhanging level of abstraction (from quark to neural network to physical movement) is as best a mental exercise. Nevertheless, it's satisfy my need to see the world in black and white, buahahaha :-).

The following are specific preferences whose origin is quite well defined:
1. Food preferences are very biological. Although the exact biological mechanism of food preferences may not be fully known, but there is no doubt that hormone is very influential in shaping food preferences and food regulation.
2. Drugs (alcohol, nicotine, caffeine, and the so called drugs like cannabis and LSD, cocaine and amphetamines, morphine and heroine, and benzodiazepines [valium]) preferences are surprisingly a balanced mix of biological and non-biological origin..
3. Sexual preferences are biological. But sexual fetishes are both biological and non-biological.
4. Mating preferences, mostly derived using evolutionary psychology, is mostly biological. This biological cause is inferred from the consistency of mating preferences across cultures, even in isolated societies.

For complex or high level preferences such as preference in ideology, see the witty but not exactly comprehensive version of origin of preference.

Leave a comment of what you would like me to expand further.

Tool to be an informed voter

Commenting on The Future of Voting from Dilbert Blog, I'd like to talk about Scott's suggestion for making voters more informed. He suggested a website that summarized arguments of issues. The summarization is structured so that points and counterpoints can be added easily with links to proper sources or evidences. He also suggested a ranking system so that the better arguments are more visible.

I have thought about creating a website implementing such tool ever since I have difficulty following arguments in a mailing list about evolution. Too bad I don't have that much leisure time anymore to play with various projects. But I did find some things I'd like to share:

1. Many people already thought about such tool, one even show a prototype on issue of abortion. But I cannot find it anymore, sorry..

2. One major problem with the existing tools is how to assimilate all existing information in a glance, or even assimilating only relevant information in a glance.

3. Presenting relevant information is difficult. Because stating/coding the request of we consider relevant, is complicated. It's complicated because either:
a. we must know the structure of relevancy in the issue, which automatically means that we already know a great deal about relationship between arguments on this issue, which defeat the purpose of having this tool in the first place.
b. we give relevant keyword or state the relationship between relevant keyword and pieces of arguments we're trying to retrieve. But this result might not be what the coder intended.

4. The problem of point 2 is also related to difficulty in coding arguments into the tool. Relationship between various points and arguments must be coded well to increase tool performance in displaying relevant arguments, and it's difficult to code it well. Additionaly, increasing complexity of arguments will greatly increase coding effort required, because we need to verify that the new argument:
a. has not been coded yet.
b. does not create inconsistency.

5. The study of knowledge representation is useful, but not that useful for this project. It's not that useful because many study of practical use in knowledge representation are on implementation of computer's knowledge representation only. Study on human's knowledge representation - which might give hints on how to make coding information into tool easy or how to make retrieving information from tool easy - is still limited.

btw, for point 3b, I think it's plausible to use google search result to generate list of related relevancy from relevant keyword we entered, where the list will be used to find the relevant arguments instead of using the keyword we entered. Or we can just google the tool's database (I'm serious).

Or we can just google the internet since google try to optimize it's search engine to analyze websites in the world (read: the aggregate of all human knowledge) to generate relevant result. (I'm also not joking here)

In anyway, I bet people working for google know a lot about this things. It's my dream to work for google. :-)

A case of social engineering in collectivist society

In a mailing list I joined (subcription is by other member's reference only, sorry), there is an article about meatless day. The poster persuades readers to observe this day, while offering them a reminder service. In short, she asked people's cell phone number and email address so she can remind them of meatless day.

You probably ask, "who would give away his email address or cell number to such a stupid request? Don't people have any common sense?". The answer is "it depends on the community's culture". In community with high collectivism, giving away such information still fit the so called common sense. On the other hand, in a more individualistic community there is more concern on "why you need to know" and "mind your own business" thus such request is unlikely to be responded.

Regardless of whether she had any bad intention, such as to sell contact numbers to spammer and telemarketers, this is an example of social engineering.

On Scott's mind 1: Finding causality

I just read "On the origin of preference" which extended the arguments in comment section of Econ101: Preference, questioning the origin of preference. Check out their blogs! His writing about Indonesia is consistently of high quality.

Using the question of "what is the origin of preference", I will show you how Scott Adams preference influences his approach to this question. :-)

Due to his obsession with occam's razor, he will try to find the simplest explanation on the origin of preference. The wittier it is, the more likely he will choose that explanation. He will also use evolution argument if possible since "survival of the fittest" is arguably a robust and flexible argument, that is evolution argument can support anything as long as you can explain how this anything gives human more chance to successfully reproduce. If the explanation is mocking humanity, it will be considered better.

Also consider that "What is the origin of preference" is open to various interpretation, where one of the interpretation might be answerable in a concise and witty manner.

Considering all of the above, I think he will answer that the origin of preference is cognitive dissonance. Here is how he might argue:

Given that we are allowed to twist the meaning of "preference" a bit, there is no constraint on whether preference influence decision or decision influence preference. Hell, we can even ignore the fact that cognitive dissonance has a complicated relationship with preference. Given this latitude, we can say that cognitive dissonance causes people to prefer anything they did. If the same person did an opposite thing, he would prefer the opposite thing too.

Also consider preference seems to change over time and events. If things happened and someone was forced to do things they didn't prefer, they would slowly have a preference at doing that things.

This kind of answer indignify humanity, which is something scott likes to do.

This answer also has an evolutionary argument component. Note that people whose cognitive dissonance does not change their preference, are more likely to die of boredom because they do things they don't prefer. If they die of boredom, they have less chance to reproduce. On the other hand, people whose cognitive dissonance changes their preference, will have more chance to reproduce since they are less likely to die of boredom.

On "dilbert" label

One of the few persons whose blog I subscribed to is Scott Adams'. He is the creator of Dilbert comic which is a satirical comic on corporate management. His view of corporate management can be summarized in 2 books: The Dilbert Principle and Dogbert's Top Secret Management Handbook.

His blog made me realize that Scott's mind is very similar to one of my best friend. Both of them able to entertain possible but extremely satirical yet simple hypothesis. Their view on issues such as free will, religion, democracy, morality, ethics, and human relationships, are very similar, both in their arguments and sarcastic tone. Their differences are only what they choose to believe.

For example let's look what I can infer from his latest blog "The Stuff in My Head" alone.

They are both believer of indoctrination effectiveness, not necessarily by the government, but also by institution and corporation. Therefore they believe democracy is only an illusion. And if I may add, a necessary illusion especially in countries whose power distance cultural dimension is low. This is an issue of cross-cultural psychology which deserves a new blog post.

Anyway, since they don't have much compelling desire to dignify their own existence - as indicated by how readily the make fun of themselves and humans -, they are very tolerant on considering different hypothesis that might ridiculed themselves. Semantic aside - which is impossible to set aside but let's continue for the sake of discussion -, they don't believe they have free will.

They also have a kind of resentment towards people in general.. well not exactly resentment but more like a sense of hopelessness at human in general. They also feel this strange combination of resentment and sympathy to people who have high unwaranteed self-esteem. They have this strange mixed feelings because they believe such people are inevitable yet they feel this itch when such mistakes left uncorrected. But they might finally sort that feeling out, it's difficult to tell.

..when Scott Adams die, I bet my friend can write his blog on behalf of him and no one will ever know :-) I will periodically talk about Scott's line of thinking based on my understanding of my friend.

Anyway, all posts about Scott Adams and Dilbert will be labeled "dilbert". And since almost all "dilbert" related posts will interest slashdot audience, they were likely to be labeled "slashdot" too.

Driving framework

The last couple of days I have been tutoring my brother on the art of driving. Since I failed to find any decent tips of driving in the internet, I was forced to make the tips up and create guideline along the way. Now I want to share those. In this post, I'll talk about guideline first.

Without further ado, here it is:

There are 3 components of driving environment: static, dynamic, and context dependent components. Static components is road. Dynamic components are everything that can change such as cars and pedestrians. Context dependent components are everything that depends on the situation..

If you are not familiar with the static component of an area, be cautious. You may assume that the static components always follow certain guidelines, such as a dead end will be marked however rudiment the mark is. But remember that some guidelines may not be reliable, for example a lack of continuous line in a wide road of a road pairs, do not imply a one way road. So again, be cautious.

At night, extra caution is necessary. What seems to be a smooth well-paved road may be damaged somewhere in the middle. Follow the tail of another car if available. If the driver in front is familiar with that road, all is well. If she doesn't , let her eat that damaged road or road bump so you can avoid them.

It goes without saying that you shouldn't pass another car on unfamiliar road at night. An unexpected road bump while passing another car might fly you and your car to heaven.

Back to theory, the dynamic component is the result of human interactions such as drivers and pedestrian. To account for dynamic component, you must consider not only human uncertainty, but also physical limitation.

In considering human uncertainty, be prepared that a pedestrian might suddenly step back in the middle of a road while crossing (I was in a taxi who hit such road crosser..). Also be prepared that a driver might decide to suddenly take a left turn, or right turn, or even suddenly stop. These things happen.

Luckily such erratic behaviors may be made sense by.. the static component! For a driver to suddenly turn left, most likely there is a road going left. For a driver to suddenly stop, most likely there is a change of road up there or there is an intersection. So, if you know in advance what the road will be up there, anticipate other drivers behavior by, for example, always slow down at intersection.

However unexpected a driver is, a car cannot suddenly stop immediately to halt or suddenly reach a certain speed or suddenly turns, because of physical limitation. Physical limitation are engine power per weight and momentum per breaks, which in turn define how fast can a car accelerate and deaccelerate. For example, due to engine power per weight, you know you have the time to safely move to the front of a huge truck since it can't possibly accelerate fast enough to hit you. On the other hand, because of momentum per breaks, you know you can't take a lane because that particular car cannot possibly stop in time.

If ability to measure such effect is sharpen, you will be able to see more opening while driving and accurately assess potential danger.

The third component, which is context dependent component, depends on the area. This component is very interesting because it's a complex adaptive system where the agents have collectivist culture (who are more sensitive to high context communication), but miraculously manage to avoid fatal traffic jam (local minima) and exchange role flawlessly while being a member of an arbitrary group (formed around congestion centers). In other words, the driving environment in Indonesia is analogous a collectivist society which limit is pushed to the extreme without breaking.

I might blog about it in the future.

Anyway, in practice, context dependent component basically requires you to observe and learn interaction between cars and pedestrians. Try to experience different situations so you finally know for certain: when you can finally do the difficult U turn with all that cars moving so fast and somehow that speeding car know that he is the one who should stop, or when you deserved that new lane without pissing people of in a traffic jam. Once you know such moments, congratulations! You have been successfuly assimilated into the system.

Afterward, you can slowly push the limit to your advantage without disrupting the system..

The invulnerable self-esteem

I have stated that self-esteem is a fragile creature that depends on the stability of it's environment to stay intact. But there is an unusual way to create a high self-esteem that does not depend on environment. The method is what I call a nihilist method.

Some people discover the nihilist method because their educational background or mental exploration, lead them to an appreciation that self-esteem might be an arbitrary construct without any intrinsic meaning. They key word here is appreciation, not understanding. Someone might understand or know the diversity of cultures in the world, but (s)he might not appreciate it.

Anyway, in short, they will think that it really truely irrelevant what they think about themselves, and they mean it.

Education background and mental exploration that lead to such appreciation are:
1. Theoretical physics
Explanation: Exploration of high level of abstraction will eventually make you wonder whether there is any intrinsic meaning to.. anything)

2. Philosophy

3. Or simply too much time to daydream :-)

Ironically, by treating self-esteem as a meaningless construct, they can gain a high and stable self-esteem. Another choice of avenue is that they will totally disregard self-esteem in their life.

An example of famous people whose self-esteem might be of this type is Scott Adams, the Dilbert creator. Given his ability to entertain different hypothesis, it is not a far stretch to say that he appreciated this possible construction of self-esteem at some point or another.

There are quite many people holding this kind of self-esteem.
