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.

The boiling frog: Internet censorship (Fitna) in Indonesia.

Have you heard the story of boiling frog? Taken from wikipedia: "The boiling frog story states that a frog can be boiled alive if the water is heated slowly enough — it is said that if a frog is placed in boiling water, it will jump out, but if it is placed in cold water that is slowly heated, it will never jump out." This blog told me about a decision of a major ISP in Indonesia to censor the controversial fitna film. Regardless of whether that movie deserved to be ban or not, I fear that this censorship is the beginning of boiling frog phenomenon. The justification for the next censorships will be more and more ridiculous that it won't take too long for Indonesia returning to a police state again.. And I do think that the censorship decision is ridiculous. Yes it is probably important to ban this movie in Europe where a majority or people in power are not moslem, because the hatred towards moslem induced by that film put many minority moslems in trouble. But in Ind...

My employees are holding a strike, yay!

Today almost 80% of my employees are holding a strike. The cause was pretty simple, one old employee who had a pretty bad track record was.. verbally disciplined. For whatever reason, he couldn't accept that reprimand so he told his work friends. Now, some of those friends were talented provocators (really. they were pretty good..) . I had awared of them since years ago but they behave well enough so... They coordinate a strike bringing almost 80% of them. The detail is rather sketchy since I wasn't present when the incidence happen. I'll update later. But one thing for sure, I now have a reasonable basis to fire those provocators. Yay! But now I must deal with some future consequences... *sigh*
