Education Singapore

shared by Weiye Loh on 22 Sep 10 - No Cached
  • On paper, Singaporean education is great. Our universities are in the Top 200 in the Times Higher Education list. We win Olympiads all the time. When it comes to knowing a basic inventory of facts, Singaporean education is just about the best you can get. And that is a fact.
  • So what’s missing?
  • Singapore is a true melting pot. In the past, as is today, and as will be tomorrow, many cultures came together into one. It has been lauded as one of Singapore’s big selling points – an eclectic fusion of Orient and Occident, a quaint East-meets-West mixture which happens to work. But have we taken this metaphor and looked at it from another perspective? Many cultures came together under the band of meritocracy – may the best rule, and may they rule with wisdom. And since they are the best, they are paid the best money one can get too. This is the fire which managed to melt, or should i say meld East and West into a functioning whole. And since we are such fans of meritocracy, society has been geared in that direction too. This melting pot which is Singapore has had certain repercussions, which the post I have linked to above shows. It seems that in developing the concept of meritocracy, what “The Best” is was artificially defined. And in artificially defining something, you create an artificial standard to compare everything against. In doing so, everything else becomes irrelevant. It creates a strong tendency towards conformity, which is the negative result of the melting pot. The individual loses his/her uniqueness and becomes part of this stew of uniformity. In school, you are told to study hard, you are told what you have to study, without any care as to what you actually think.

  • Individuality is not really encouraged, because there is a tried-and-tested formula for becoming good. Why would any sane person abandon that?
  • And, by the by, an artificial standard of what is Good is also very easy to objectify. Just look at the obsession with grades, and the thought that cramming is the panacea for all your examination woes.
  • in the midst of all that, something has gone missing. I think learning what it is to be a person has gone missing in Singaporean education. People assume that a sense of identity is a coming-of-age thing, that it will come with the times. And for the most part, that really is true. But this article is a case in point. I think that the melting pot has left little room for the individual to develop, since all differences have been swept away, and everyone is chasing after this artificial Good.
  • That having an individual opinion is sometimes seen as trouble-making is a symptom of this problem. That people know a lot, but don’t have a view on them is also a symptom of this problem. It’s all about working hard in Singapore. But after that, what’s left? Yet, working hard and sticking to that same old success formula is so ingrained into our society that it is hard to see how concrete change can come about.
  • We should be asking questions if “The Good” we are striving to be was misconstrued. We should be asking “What is Good for Me? What Should I Be?” And these are questions which should be asked, not only during the formative years of adolesence, but also constantly throughout one’s adult life. And these are questions which don’t have a textbook answer. And the asking of such questions should be cultivated in our youth, when they are ready for it.
  • We shouldn’t be doing what we are doing now – filling their lives with so much work, so much obsession with chasing after this artificial good that they don’t have time to stop and reflect. Nor will forcing them to reflect help – because then, it will be more work, and what’s worse, their reflections may be graded. The melting pot comes into play again. As educators, one should ask if we want to produce smart people or if we want  to produce wise people.

Ethics

shared by Weiye Loh on 26 Dec 09 - Cached
  • Food choices are often like that: difficult to articulate yet strongly held. And lately, debates over food choices have flared with particular vehemence.
  • Gary Steiner, a philosopher at Bucknell University, argued on the Op-Ed page of The New York Times that people should strive to be “strict ethical vegans” like himself, avoiding all products derived from animals, including wool and silk. Killing animals for human food and finery is nothing less than “outright murder,”
  • we might consider that plants no more aspire to being stir-fried in a wok than a hog aspires to being peppercorn-studded in my Christmas clay pot.
  • ...11 more annotations...
  • Plants are lively and seek to keep it that way.
  • their keen sensitivity to the environment, the speed with which they react to changes in the environment, and the extraordinary number of tricks that plants will rally to fight off attackers and solicit help from afar
  • When plant biologists speak of their subjects, they use active verbs and vivid images. Plants “forage” for resources like light and soil nutrients and “anticipate” rough spots and opportunities.
  • Plants can’t run away from a threat but they can stand their ground. “They are very good at avoiding getting eaten,”
  • At the smallest nip to its leaves, specialized cells on the plant’s surface release chemicals to irritate the predator or sticky goo to entrap it. Genes in the plant’s DNA are activated to wage systemwide chemical warfare, the plant’s version of an immune response.
  • in less than 20 minutes from the moment the caterpillar had begun feeding on its leaves, the plant had plucked carbon from the air and forged defensive compounds from scratch.
  • Just because we humans can’t hear them doesn’t mean plants don’t howl. Some of the compounds that plants generate in response to insect mastication — their feedback, you might say — are volatile chemicals that serve as cries for help. Such airborne alarm calls have been shown to attract both large predatory insects like dragon flies, which delight in caterpillar meat, and tiny parasitic insects, which can infect a caterpillar and destroy it from within.
  • certain plants can sense when insect eggs have been deposited on their leaves and will act immediately to rid themselves of the incubating menace. They may sprout carpets of tumorlike neoplasms to knock the eggs off, or secrete ovicides to kill them
  • when a female cabbage butterfly lays her eggs on a brussels sprout plant and attaches her treasures to the leaves with tiny dabs of glue, the vigilant vegetable detects the presence of a simple additive in the glue, benzyl cyanide. Cued by the additive, the plant swiftly alters the chemistry of its leaf surface to beckon female parasitic wasps. Spying the anchored bounty, the female wasps in turn inject their eggs inside, the gestating wasps feed on the gestating butterflies, and the plant’s problem is solved.
  • seedlings of the dodder plant, a parasitic weed related to morning glory, can detect volatile chemicals released by potential host plants like the tomato. The young dodder then grows inexorably toward the host, until it can encircle the victim’s stem and begin sucking the life phloem right out of it. The parasite can even distinguish between the scents of healthier and weaker tomato plants and then head for the hale one.
  • It’s a small daily tragedy that we animals must kill to stay alive. Plants are the ethical autotrophs here, the ones that wrest their meals from the sun. Don’t expect them to boast: they’re too busy fighting to survive.

Carbon Tax Carbon Trade Policy Economy Political Economy

shared by Weiye Loh on 16 Mar 11 - No Cached
  • It is here where I think that Gillard has made a bad bet. Carbon pricing is supposed to create jobs by making fossil fuels appreciably more expensive, thereby creating a market signal that disfavors carbon-intensive industry and stimulates less carbon-intensive economic activity. The economic parts of theory seem sound enough.
  • However, it is the political realities that the theory does not account for.  Australia's economy is very carbon intensive (PDF). Thus, if carbon pricing were to work exactly as the Prime Minister describes, it will necessary lead to a great deal of economic dislocation and change -- Consider that to meet the 5% emissions reduction target (from 2000 levels), without relying on offsets or other tricks, implies that Australia's economy would need to become as carbon efficient as Japan's by the end of this decade. How such a profoundly disruptive transitional period would be managed is the one issue that advocates of a high carbon price have never really dealt with -- the market's invisible hand will take care of it I guess.
  • How does one become "reskilled"?  Without an explanation, many people will translate "reskilled" to mean "unemployed".  The oft-stated idea that the proceeds of a carbon tax will be used to compensate those who fact higher costs does not address the issue of dislocation in the economy. There is a element of "magical thinking" in the idea that transforming a national economy starts with a simple decision: . . . clean energy will open up opportunities we are only just beginning to imagine. Those opportunities begin with that simple but momentous decision: Putting a price on carbon. Friends, a price on carbon is the cheapest way to drive investment and jobs.

  • There are only two realistic outcomes here. One is that the carbon tax proposal is scrapped. With this speech it seems highly unlikely that Gillard will be the one doing any scrapping.  So it would probably be via an election or a change in leadership, such as if Kevin Rudd becomes captain of the Brisbane Broncos. The second possible outcome is that the carbon pricing is watered down so far that its enactment allows Labor to claim success while limiting any actual impact from the tax on the economy.  Of course, that would undercut its stated purpose -- to transform the economy.
  • A better strategy is the one proposed in The Climate Fix -- start with a very low carbon tax, one that is politically acceptable, and use the proceeds to invest in innovation. The carbon price would rise over time as the fruits of innovation make it politically acceptable to raise that price.  I expect that Australia will soon provide (yet aonpther) lesson in how not to try to put a price on carbon.

    In the face of opinion polls showing a lack of support for her proposed carbon tax, Julia Gillard today has delivered a speech that indicates that she is willing to wager her future on this issue (The speech is here in PDF).

Complex System Black Swan Falsifiability Politics Economics

shared by Weiye Loh on 01 May 11 - No Cached
  • It is both misguided and dangerous to push unobserved risks further into the statistical tails of the probability distribution of outcomes and allow these high-impact, low-probability "tail risks" to disappear from policymakers' fields of observation.
  • Such environments eventually experience massive blowups, catching everyone off-guard and undoing years of stability or, in some cases, ending up far worse than they were in their initial volatile state. Indeed, the longer it takes for the blowup to occur, the worse the resulting harm in both economic and political systems.
  • Seeking to restrict variability seems to be good policy (who does not prefer stability to chaos?), so it is with very good intentions that policymakers unwittingly increase the risk of major blowups. And it is the same misperception of the properties of natural systems that led to both the economic crisis of 2007-8 and the current turmoil in the Arab world. The policy implications are identical: to make systems robust, all risks must be visible and out in the open -- fluctuat nec mergitur (it fluctuates but does not sink) goes the Latin saying.
  • ...21 more annotations...
  • Just as a robust economic system is one that encourages early failures (the concepts of "fail small" and "fail fast"), the U.S. government should stop supporting dictatorial regimes for the sake of pseudostability and instead allow political noise to rise to the surface. Making an economy robust in the face of business swings requires allowing risk to be visible; the same is true in politics.
  • Both the recent financial crisis and the current political crisis in the Middle East are grounded in the rise of complexity, interdependence, and unpredictability. Policymakers in the United Kingdom and the United States have long promoted policies aimed at eliminating fluctuation -- no more booms and busts in the economy, no more "Iranian surprises" in foreign policy. These policies have almost always produced undesirable outcomes. For example, the U.S. banking system became very fragile following a succession of progressively larger bailouts and government interventions, particularly after the 1983 rescue of major banks (ironically, by the same Reagan administration that trumpeted free markets). In the United States, promoting these bad policies has been a bipartisan effort throughout. Republicans have been good at fragilizing large corporations through bailouts, and Democrats have been good at fragilizing the government. At the same time, the financial system as a whole exhibited little volatility; it kept getting weaker while providing policymakers with the illusion of stability, illustrated most notably when Ben Bernanke, who was then a member of the Board of Governors of the U.S. Federal Reserve, declared the era of "the great moderation" in 2004.
  • Washington stabilized the market with bailouts and by allowing certain companies to grow "too big to fail." Because policymakers believed it was better to do something than to do nothing, they felt obligated to heal the economy rather than wait and see if it healed on its own.
  • The foreign policy equivalent is to support the incumbent no matter what. And just as banks took wild risks thanks to Greenspan's implicit insurance policy, client governments such as Hosni Mubarak's in Egypt for years engaged in overt plunder thanks to similarly reliable U.S. support.
  • Those who seek to prevent volatility on the grounds that any and all bumps in the road must be avoided paradoxically increase the probability that a tail risk will cause a major explosion.
  • In the realm of economics, price controls are designed to constrain volatility on the grounds that stable prices are a good thing. But although these controls might work in some rare situations, the long-term effect of any such system is an eventual and extremely costly blowup whose cleanup costs can far exceed the benefits accrued. The risks of a dictatorship, no matter how seemingly stable, are no different, in the long run, from those of an artificially controlled price.
  • Such attempts to institutionally engineer the world come in two types: those that conform to the world as it is and those that attempt to reform the world. The nature of humans, quite reasonably, is to intervene in an effort to alter their world and the outcomes it produces. But government interventions are laden with unintended -- and unforeseen -- consequences, particularly in complex systems, so humans must work with nature by tolerating systems that absorb human imperfections rather than seek to change them.
  • What is needed is a system that can prevent the harm done to citizens by the dishonesty of business elites; the limited competence of forecasters, economists, and statisticians; and the imperfections of regulation, not one that aims to eliminate these flaws. Humans must try to resist the illusion of control: just as foreign policy should be intelligence-proof (it should minimize its reliance on the competence of information-gathering organizations and the predictions of "experts" in what are inherently unpredictable domains), the economy should be regulator-proof, given that some regulations simply make the system itself more fragile. Due to the complexity of markets, intricate regulations simply serve to generate fees for lawyers and profits for sophisticated derivatives traders who can build complicated financial products that skirt those regulations.
  • The life of a turkey before Thanksgiving is illustrative: the turkey is fed for 1,000 days and every day seems to confirm that the farmer cares for it -- until the last day, when confidence is maximal. The "turkey problem" occurs when a naive analysis of stability is derived from the absence of past variations. Likewise, confidence in stability was maximal at the onset of the financial crisis in 2007.
  • The turkey problem for humans is the result of mistaking one environment for another. Humans simultaneously inhabit two systems: the linear and the complex. The linear domain is characterized by its predictability and the low degree of interaction among its components, which allows the use of mathematical methods that make forecasts reliable. In complex systems, there is an absence of visible causal links between the elements, masking a high degree of interdependence and extremely low predictability. Nonlinear elements are also present, such as those commonly known, and generally misunderstood, as "tipping points." Imagine someone who keeps adding sand to a sand pile without any visible consequence, until suddenly the entire pile crumbles. It would be foolish to blame the collapse on the last grain of sand rather than the structure of the pile, but that is what people do consistently, and that is the policy error.
  • Engineering, architecture, astronomy, most of physics, and much of common science are linear domains. The complex domain is the realm of the social world, epidemics, and economics. Crucially, the linear domain delivers mild variations without large shocks, whereas the complex domain delivers massive jumps and gaps. Complex systems are misunderstood, mostly because humans' sophistication, obtained over the history of human knowledge in the linear domain, does not transfer properly to the complex domain. Humans can predict a solar eclipse and the trajectory of a space vessel, but not the stock market or Egyptian political events. All man-made complex systems have commonalities and even universalities. Sadly, deceptive calm (followed by Black Swan surprises) seems to be one of those properties.
  • The system is responsible, not the components. But after the financial crisis of 2007-8, many people thought that predicting the subprime meltdown would have helped. It would not have, since it was a symptom of the crisis, not its underlying cause. Likewise, Obama's blaming "bad intelligence" for his administration's failure to predict the crisis in Egypt is symptomatic of both the misunderstanding of complex systems and the bad policies involved.
  • Obama's mistake illustrates the illusion of local causal chains -- that is, confusing catalysts for causes and assuming that one can know which catalyst will produce which effect. The final episode of the upheaval in Egypt was unpredictable for all observers, especially those involved. As such, blaming the CIA is as foolish as funding it to forecast such events. Governments are wasting billions of dollars on attempting to predict events that are produced by interdependent systems and are therefore not statistically understandable at the individual level.
  • Political and economic "tail events" are unpredictable, and their probabilities are not scientifically measurable. No matter how many dollars are spent on research, predicting revolutions is not the same as counting cards; humans will never be able to turn politics into the tractable randomness of blackjack.
  • Most explanations being offered for the current turmoil in the Middle East follow the "catalysts as causes" confusion. The riots in Tunisia and Egypt were initially attributed to rising commodity prices, not to stifling and unpopular dictatorships. But Bahrain and Libya are countries with high gdps that can afford to import grain and other commodities. Again, the focus is wrong even if the logic is comforting. It is the system and its fragility, not events, that must be studied -- what physicists call "percolation theory," in which the properties of the terrain are studied rather than those of a single element of the terrain.
  • When dealing with a system that is inherently unpredictable, what should be done? Differentiating between two types of countries is useful. In the first, changes in government do not lead to meaningful differences in political outcomes (since political tensions are out in the open). In the second type, changes in government lead to both drastic and deeply unpredictable changes.
  • Humans fear randomness -- a healthy ancestral trait inherited from a different environment. Whereas in the past, which was a more linear world, this trait enhanced fitness and increased chances of survival, it can have the reverse effect in today's complex world, making volatility take the shape of nasty Black Swans hiding behind deceptive periods of "great moderation." This is not to say that any and all volatility should be embraced. Insurance should not be banned, for example.
  • But alongside the "catalysts as causes" confusion sit two mental biases: the illusion of control and the action bias (the illusion that doing something is always better than doing nothing). This leads to the desire to impose man-made solutions
  • Variation is information. When there is no variation, there is no information. This explains the CIA's failure to predict the Egyptian revolution and, a generation before, the Iranian Revolution -- in both cases, the revolutionaries themselves did not have a clear idea of their relative strength with respect to the regime they were hoping to topple. So rather than subsidize and praise as a "force for stability" every tin-pot potentate on the planet, the U.S. government should encourage countries to let information flow upward through the transparency that comes with political agitation. It should not fear fluctuations per se, since allowing them to be in the open, as Italy and Lebanon both show in different ways, creates the stability of small jumps.
  • As Seneca wrote in De clementia, "Repeated punishment, while it crushes the hatred of a few, stirs the hatred of all . . . just as trees that have been trimmed throw out again countless branches." The imposition of peace through repeated punishment lies at the heart of many seemingly intractable conflicts, including the Israeli-Palestinian stalemate. Furthermore, dealing with seemingly reliable high-level officials rather than the people themselves prevents any peace treaty signed from being robust. The Romans were wise enough to know that only a free man under Roman law could be trusted to engage in a contract; by extension, only a free people can be trusted to abide by a treaty. Treaties that are negotiated with the consent of a broad swath of the populations on both sides of a conflict tend to survive. Just as no central bank is powerful enough to dictate stability, no superpower can be powerful enough to guarantee solid peace alone.
  • As Jean-Jacques Rousseau put it, "A little bit of agitation gives motivation to the soul, and what really makes the species prosper is not peace so much as freedom." With freedom comes some unpredictable fluctuation. This is one of life's packages: there is no freedom without noise -- and no stability without volatility.∂
