On Godwin's law

As an online discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1.

— Godwin's Law (as cited by Wikipedia)

I have seen online, on a number of occasions, people using the above observation as some way of refuting or diminishing any argument that mentions Nazis or Hitler. Someone recently told me on Quora that my comparison suffers from being "Hitler fallacy".

Here is my response:

Why is it a fallacy?

For example, when Bush was asked: "How did you decide that torture was moral?", he answered: "I asked my lawyers, and they told me it was not illegal."

The best way to show through an example that such reasoning is wrong is to evoke the history of Nazis: everything they did was also legal, according to the laws of their democratically elected government.

Why is that logically wrong?

It's one thing if someone says that "Bush is like Hitler because...". Clearly, that's very silly, because he is nothing like Hitler, at least in quantity. But there is nothing wrong with saying that "Bush committed the same mistake as Hitler by thinking that legal equals moral", or, better yet, "We can see that Bush's reasoning is wrong by applying it to Nazis".

In my opinion, constant appeal to Godwin's Law is quite ridiculous. There is nothing logically wrong with using Nazis as a counter-example in morality or law. The episode of Nazism, WWII, Holocaust, Nuremberg trials (where people were tried by an international community for following their country's law and their superiors' orders), etc., is such a stark point in the recent history that not drawing lessons from it would be foolish.

Of course, one can also say: "Keeping slaves in the South was also legal, while helping them escape was illegal in both North and South", but I don't think it resonates quite so much. Maybe if I was Black and not Jewish, it would.

One critique one may offer is that comparing some act or thought to something Hitler did or thought is not in and of itself an argument for its immorality. For instance, saying that wearing shorts is immoral because Hitler wore them is clearly silly. But I would think it was self-evident that genocide is immoral. Of course, one does not need to bring Hitler as an example. But, when making an argument, one uses the most effective ammunition possible. Sure, I can say, "in a country where genocide is legal, you have an example of something that is legal and yet immoral". But that's is much less powerful than saying: "Under the Nazi regime, hiding Jews was illegal, while killing them was legal".


So, henceforth I am drawing CrawlingAxe's Law:

Someone who uses Godwin's Law indiscriminately clearly doesn't understand the difference between reduction and an analogy. If I say that A is like B in aspect X, I am not saying that A is the same as B in all aspects.

On political agenda

I want to address the question of political agenda (now that I've got one...).

As a background, imagine the following conversation: a student comes to a Chabad House rabbi on campus and asks him why the rabbis of N. America did not pasken against slavery, if one might conceive that there was room to do so, in particular, the way it was being carried out. (This example is not from my experience, although I did ask a similar question once.) The rabbi might answer that the poskim really did not think that it was wrong from halachic perspective (although it might have been morally wrong), but another answer one might hear is: "Maybe because they did not have a political agenda".

I want to address this answer. Political agenda is assumed to attenuate one's objectivity. It is especially damaging, then, when intervening with the investigations calling for one. For instance, it's not as much a problem when choosing a salad: "this doesn't taste good because it's not organic" may be a silly thing to say, but after all, if it doesn't taste good to one, so be it. It is more damaging in natural sciences, for instance, since there the object is not to discover how one feels about something, but what something is. "White men are superior to women and minorities" or, on the other side of the spectrum, "global warming is caused by industrial pollution" are examples of conclusions that may have been influenced by a political agenda.

I think, however, that there is also a positive side to the political agenda (and potentially a negative side to not having it): it alerts one to a potential issue. I don't know whether slavery, as practiced in N. America, was halachically problematic. But if I know that it was morally wrong (and the general assumption is that there is a strong degree of correlation between morality and halacha, especially bein adam l'chaveiro), I may be prompted to investigate more into the halacha. On the other hand, if I don't know it's wrong (or have never seriously considered such a view), because I have not been exposed to extra-hallachic analyses of morality, I may never look into all the details. (I am not suggesting that Torah is somehow deficient as the lone source of morality, but people are deficient in understanding morality from Torah and especially halacha and may benefit from the "outside" analysis.)

In fact, I think most people have a political agenda one way or another. At the minimum it is what I call the inertial agenda: to preserve the status quo (I am tempted to call this political vector conservative, but it can act in a liberal direction too: for instance, one raised in a democratic society may never assume there is anything wrong with democracy from moral or legal points of view).

Thus, being exposed to various political agendas (as well as scientific, economic, or grammatic ones) may:

1. alert one to potential issues that one might not have thought of before
2. battle one's already existing agendas or prejudices that might affect one's objectivity.

Hitchens on Kennedy

I am quite enjoying Hitchens's biography. I am reading it not from cover to cover but going from topic to topic. The latest two topics were Edward Said and buggery in English boarding schools.

Anyway, I thought this was funny (more quotes on the question of authority to follow):

In my very first term [at Cambridge], in October 1962, President Kennedy went to the brink, as the saying invariably goes, over Cuba. I shall never forget where I was standing and what I was doing on the day he nearly killed me. (It was on the touchline, being forced to watch a rugby game, that I overheard some older boys discussing the likelihood of our annihilation.) 

At the close of the BBC’s programming that night, Richard Dimbleby enjoined all parents to please act normally and send their children to school in the morning. This didn’t apply to those of us boarders who were already at school. We were left to wonder how the adult world could be ready to gamble itself, and the life of all the subsequent and for that matter preceding generations, on a sordid squabble over a banana republic. I wouldn’t have phrased it like that then, but I do remember feeling furious disgust at the idea of being sacrificed in an American quarrel that seemed largely to be of Kennedy’s making in the first place. 

I have changed my mind on a number of things since, including almost everything having to do with Cuba, but the idea that we should be grateful for having been spared, and should shower our gratitude upon the supposed Galahad of Camelot for his gracious lenience in opting not to commit genocide and suicide, seemed a bit creepy. When Kennedy was shot the following year, I knew myself somewhat apart from this supposedly generational trauma in that I felt no particular sense of loss at the passing of such a high-risk narcissist. If I registered any distinct emotion, it was that of mild relief.

Finding AHPs

AHP = average y-distance between the blue and the green dots.

Since apparently in my last action potentials post it was not clear what I was looking for, I decided to post the above graph.

I found voltage thresholds (blue dots) and action potentials' troughs (green squares) to find the average difference between them (after-hyperpolarization potential). I did not find a good automated way of finding voltage threshold, so I just hard-coded the minimal value for dv/dt: once the trace crossed it, the voltage at which it was crossed was designated as voltage threshold. If you look at the graph, you can see that it worked rather well, but I would still like to find it in a more elegant way (I tried finding local third-derivative maxima, but had some problems with the function).

The troughs were obtained through findpeaks function (Signal Processing Toolbox package), such that:

[p, i_p] = findpeaks (f);

saves the values of peaks as p and their indexes as i_p. Since in my case I was looking for troughs, I inverted my trace (and then inverted the peaks back):

[troughs, i_t] = findpeaks (trace);
troughs = –troughs;

If you want to plot the troughs, you can just write:

plot (i_t, troughs, 'og'); %green circles
plot (trace, 'r'); %red trace

dv/dt was obtained through function diff, such that:

dn_dx = diff (f, n); %produces n-th derivative of f

In order to analyze the data, I first had to separate out individual action potentials:

function [output] = findAPs (input_trace)

    barrage = input_trace; %select APs to analyze from the trace

    %[peaks, i_p] = findpeaks(barrage); %if you want to analyze peaks

    [~, i_t] = findpeaks (-barrage); %obtain x-values for troughs

    APs = cell(length(i_t), 1); %allocate empty cell space

    %adding first and last pts of barrage to minima:
    minima = [1; i_t; length(barrage)];

    %separating APs:
    for i = 1:length(minima)-1
        APs{i} = barrage(minima(i):minima(i+1));
    end

    output = APs; %return a cell of AP traces
 end

Then I found dv/dt for each AP and selected for the first value above the accepted threshold level to find the threshold:

function [output] = find_v_th (APs)
    v_th = struct([]);

    for i = 1:length(APs)
        dv = diff (APs{i}, 1); %first derivative

        %find first instance of dv/dt>0.001:
        v_th_i = find (dv>0.001, 1, 'first')-1; %offset by one b/c of diff

        if (v_th_i) %if v-threshold was found, enter voltage and x vals
            v_th(i).v = APs{i}(v_th_i);
            v_th(i).x = v_th_i;
        else
            v_th(i).v = [];
            v_th(i).x = [];
        end
    end

    output = v_th;
end

Plotting dv/dt was the same as plotting troughs. To find AHP, one can create an array of trough values and threshold values and subtract one from another, or just average each array and subtract the averages. To plot the AHPs and dv/dt's took a little more effort, since I had to put the APs and dv/dt's with AHP values back together in one barrage, making sure to preserve the x-values. I recommend doing all this in object-oriented manner.

Impossibility of voluntary slavery

From Murray Rothbard's Ethics of Liberty, "Property Rights and the Theory of Contracts":

Let us pursue more deeply our argument that mere promises or expectations should not be enforceable. The basic reason is that the only valid transfer of title of ownership in the free society is the case where the property is, in fact and in the nature of man, alienable by man. All physical property owned by a person is alienable, i.e., in natural fact it can be given or transferred to the ownership and control of another party. I can give away or sell to another person my shoes, my house, my car, my money, etc. But there are certain vital things which, in natural fact and in the nature of man, are inalienable, i.e., they cannot in fact be alienated, even voluntarily. 

Specifically, a person cannot alienate his will, more particularly his control over his own mind and body. Each man has control over his own mind and body. Each man has control over his own will and person, and he is, if you wish, “stuck” with that inherent and inalienable ownership. Since his will and control over his own person are inalienable, then so also are his rights to control that person and will. That is the ground for the famous position of the Declaration of Independence that man’s natural rights are inalienable; that is, they cannot be surrendered, even if the person wishes to do so. 

Or, as Williamson Evers points out, the philosophical defenses of human rights "are founded upon the natural fact that each human is the proprietor of his own will. To take rights like those of property and contractual freedom that are based on a foundation of the absolute self-ownership of the will and then to use those derived rights to destroy their own foundation is philosophically invalid".

Hence, the unenforceability, in libertarian theory, of voluntary slave contracts.

 Read on.

Question to mathematicians

I have data with a bunch of traces of action potentials (top graph).

I want to find the average after-hyperpolarization potential (AHP), the voltage difference between where the action potential "takes off" on its way up (known as "voltage threshold") and the trough of its overshoot on its way down, i.e., the arrow on the top graph, which presumably corresponds to the arrow on the bottom graph.

What's the easiest way of doing that?

(Note: I am looking for an algorithm to automatize the calculation. I am working on Matlab, but it can be an abstract algorithm, although specific enough to implement without any additional knowledge: i.e., don't just say: "Fit the curves to Hudgkin-Huxley equation and find the intercepts".)

Re: libertarians re: Israel

I am posting this here not just to share my thoughts, but also so that I have an easy place to copy-paste my answer from.

As a context, many libertarians disagree with Israel's 'right to defend itself', because according to them, it exists on a land stolen from Arabs in 1948, when 'Palestinian Arabs' left or were expelled from their lands. This is not the place to address that claim (and I don't have all the facts -- and neither do most people -- and if I did, there are many nuances to consider). What I am addressing here is Israelis' right to defend themselves, either individually or collectively through the organization called State of Israel (or IDF). I am also addressing the claim that the media are not one-sided.


The media are one-sided. You can call it antisemitism or whatever label you want. Perhaps it's cheering for the "underdog" gang-like terrorists vs. the mighty state of Israel (perhaps that's also the reason why libertarian analysis is so one-sided).

Palestinians do not deal with the same thing. They have to deal with the collateral damage produced by IDF killing criminals hiding in the Palestinians' midst (with the latter ofentimes knowingly hiding them). We can argue whether Israel is a criminal organization to its own citizens by the virtue of being a state. We can also argue that perhaps injustice has happened over 60 years ago when people were displaced, or when displaced people were not allowed to return to their homes. Some might argue that injustice did not happen, and it was their fault for siding with Israeli enemy and allowing it to use their territories. Or that now, after all has been said and done, things have changed and people settled on those lands — so, the best solution is to give the displaced people recompense for their lost lands, as resettlement is not an option. Or we can argue that a resettlement must happen.

But this dispute can be solved in a civil manner. Through international arbitration, diplomacy, economic pressure, etc. It cannot be solved through Palestinian thugs shooting rockets at Russian immigrants who came to the country in the 1990s and settled in Sderot.

Imagine if I had a dispute with you over some land. You claim I stole it. I claim otherwise -- that I took it from you justly. Then a third-party tenant settled in the disputed land. If you bomb his house or shoot at his children, and I defend them by shooting back at you, *in that act* (i.e., aside from my previous presumed injustice to you) am I being a criminal? Or are you being a criminal? I think most civilized people would say the latter. And if, through shooting at you I happen to kill some bystanders (especially who willingly hid you in their midst), I don't think you can say that the bystanders are undergoing ethnic cleansing or that they are going through the same thing as the tenant's children.

If you answer to the tenant's complaint that he is living on a stolen land, his answer would be: "Let's settle this dispute in a civilized, peaceful manner through arbitration, but first, the violence must stop."

Why stimulus failed

I think this video is good —



— but somewhat misleading. It makes it sound like Obama's stimulus would not have failed if the money actually reached the intended (or, rather, advertised) targets and were not wasted or did not create unintended consequences. (I differentiate between 'intended' and 'advertised' because I believe, rather cynically, that the Federal government all along knew that the money would go to its buddies, in the usual crony-capitalist fashion.)

But the deeper point is that even if that were to happen, this money would still fail to 'stimulate' the economy. What was wrong with the economy is not that there was not enough money or spending or that it just needed a kick in the right piston to get the machine working again (see here for the rebuttal of this fallacy). The problem was not with lack of investment — but, rather, with malinvestment: during the boom phase of the business cycle, money was invested into the wrong industries (see here why this happened).

During the bust phase, the economy 'discovered' that there was after all no demand for the long-term, 'capital goods' businesses (such as construction) into which the investments had previously flowed (encouraged by the artificially low interest rates). This discovery led to contraction of the suddenly failing businesses (or, rather, businesses whose failure suddenly came in the open): their stocks dropped, they had to fire many of their employees, and even declare (or come close to declaring) bankruptcies.

This process of contraction is not only natural, following the malinvestment of the boom phase, but is in fact crucial for any 'recovery'. In order to get the economy back on the road, it was — and still is — necessary to allow the businesses that became too engorged with the malinvested capital to shed it and let the capital flow to the businesses that actually have the support of their customers (because they are successful at predicting what their customers need and want to spend money on right now). This could happen through the successful businesses buying up now-cheap equipment and land or office space of the failing businesses and hiring the suddenly unemployed workers.

By keeping the failing businesses alive or by taxing the successful businesses and redirecting the tax money towards roads or public schools, one does not reverse the problem of malinvestment. And by making interest rates even lower, thus encouraging further long-term investment unsupported by the public's spending time preference, the FED is making the problem worse!

Activating Trash

It takes a while to build up...

In response to Edmund Conway's post–break up (with Apple) letter comparing Apple with Obama, one comment said:

Apple and Obama fan here. Agree about Apple/iOS 6, but zero sourness about Obama. What does economy problem have to do with him, again? He did a damn grand job helping to smooth the landing and overseeing the takeoff. Building takes a lot longer than destroying; people forget that. So yeah, no matter how hard I look, I can’t see anything sour in my Obama relationship, so you’re wrong that all fans would admit that.

My response:

You are right, orchestrating and building a new bubble takes longer than contracting from an old one. It takes days or weeks for people to realize that the papers they are holding are trash. It takes years to build up the con. 

Maybe the administration has been busy choosing malinvestments into which new commodity should be encouraged.  

Perhaps it should be the tulips again. The government should declare that if you invest in tulips, but your investment flops, the government will bail you out. Then, when the over-blown tulip investments burst and crash the markets, the government should provide a ‘soft landing’ by bailing out the tulip farmers and prolonging the resulting contraction from a month to another four years. 

Obama should learn from the Japanese. They have been in stagnation for three decades. Four years are like a butterfly’s dream to them.

Government vs. OSs

Imagine if switching governments was this easy. You wouldn't have to move. You wouldn't have pack your stuff or sell it. You wouldn't have to search for a new place to live, for a new community to fit it, for new friends and contacts and a new place to buy cheap potatoes.

You would just go online and cancel your subscription to one government while subscribing for the protection and (possibly) legal services of another. You may need to change the sticker or some little flag outside your door: 'Protected by AMS Northwest'. And that's it.

On the eve of American elections 2012

I just want to say for the record that tomorrow I will have no sympathy for the Conservatives. You had a chance to nominate one guy who actually stood for the principles that you supposedly stand for: individualism, personal freedom, free markets, limited government, and honesty. AND he would appeal to a lot of liberals and independents actually giving you a chance to have Obama defeated. One thing he was not is a warmonger. But no... you needed a warmonger, and you nominated one, even though he is almost a carbon copy of the current president whom you hate so much.

Well, for that you will get four more years of socialism... and warmongering. So, don't complain. You are practically getting what you asked for, just under a different label.

Anyway, I personally think Obama is a better choice. When we are worse off in four years (as we would be under Romney as well), at least the free markets won't be blamed.

Reification of civilization

Someone posted a link to the following article on the Facebook: 'A Point Of View: Is China more legitimate than the West?'

In my first talk I explained that China is not primarily a nation-state but a civilisation-state. For the Chinese, what matters is civilisation. For Westerners it is nation. The most important political value in China is the integrity and unity of the civilisation-state.

They see the state as the embodiment and guardian of Chinese civilisation. Its most important responsibility - bar none - is maintaining the unity of the country. A government that fails to ensure this will fall.

But does the Chinese state, you may well ask, really enjoy legitimacy in the eyes of its people?

Take the findings of Tony Saich at Harvard's Kennedy School of Government. In a series of surveys he found that between 80 and 95% of Chinese people were either relatively or extremely satisfied with central government.

Or take the highly respected Pew Global Attitudes surveys which found in 2010, for example, that 91% of Chinese respondents thought that the government's handling of the economy was good (the UK figure, incidentally was 45%).

Such high levels of satisfaction do not mean that China is conflict-free.

On the contrary, there are countless examples of protest action, such as the wave of strikes in Guangdong province for higher wages in 2010 and 2011, and the 150,000 or more so-called mass incidents that take place every year - generally protests by farmers against what they see as the illegal seizure of their land by local authorities in cahoots with property developers.

Here is my response:

The biggest problem with the article is that it is full of logical holes, non-sequiturs. Let's assume that the Chinese people look at themselves as a civilization, not some chance community (such as the American society). Therefore what? Why shouldn't the government that keeps that civilization together be democratically elected (not that I am a friend of the democracy; I am just examining the argument)? How do we know that the government that came to power through some oligarchic bureaucratic power struggle will be more effective at this allegedly nationally-sought goal than a democratically elected one?

Or, for that matter, why is the government's job to 'preserve the unity of Chinese civilization' (whatever that means; after all, the people in the country don't speak the same language in the south and in the north; there are many different ethnicity, many styles of food and music, etc., etc.)? Perhaps private organization in charge of the particular aspects of the culture — and in charge of unifying them and standardizing them — will be more effective. If such unification and standardization is indeed what the Chinese people want, they can choose those organization themselves, and the organizations will compete on the free markets for the effectiveness of this 'service'.

Then there is the moral argument. As long as you feed the slaves and keep them happy, your forced ownership of them is justified. (I mean, yeah, sometimes the slaves complain because there is not enough food and the work conditions created by the overseers are harsh, but they don't object to being in slavery. Well, some do, but who cares about those few?)

95% support? That's nothing. In N. Korea, 100% support the Dear Leader. In Russia, in some regions more than 100% voted for Putin.

The idea about Chinese economy overcoming American in six years is a myth. Within six years it will crash. Laws of nature cannot be violated so easily. And today, yes, the GDP figures are high, but people are still living in poverty. During WWII, GDP figures were high in the US too. And living conditions were worse than before the war — the figures were a result of war spending on bullets and tanks.

In regards to China being not a nation but a civilization (and that's why a few mafia members can decide for one third of the world's population how to live), this is my favorite concept, reification:

Reification (also known as concretism, or the fallacy of misplaced concreteness) is a fallacy of ambiguity, when an abstraction (abstract belief or hypothetical construct) is treated as if it were a concrete, real event, or physical entity. In other words, it is the error of treating as a concrete thing something which is not concrete, but merely an idea.

In other words, 'civilization', 'tzibbur', 'community', 'hurricane', 'forest' are all concepts. They are useful concepts for understanding complex phenomena and emergent properties, but the moment we think of themselves as having an independent life of their own (such as 'tzibbur owning land'), we make the mistake of reification: falsely making something abstract into concrete.

But, in fact, this is a useful article. If we understand the exact points in which it is wrong, we will also understand why Western democracy is a failed liberal system that does not liberate people from governmental oppression, but in fact simply kicks the can of oppression down the road.

It reminds me of Peter Singer's (and the like) articles about abortion, in which he argues in favor of infanticide (e.g., of sick babies), because after all, there is not much difference between an infant and a fetus. Once we understand why he is wrong (that it's ok to kill newborns), we can understand why abortion is also wrong.

USSR in NJ

From an e-mail I sent to my in-laws:

The situation on the East Coast, where the governor of NJ made profiteering forbidden, is the best example why I am a libertarian. NOT (only) because I care about the gas companies and their natural rights. But because profiteering is the best way to attract business — to attract import of gas, generators, construction crews, shovels, whatever is needed, into the disaster zone. Why the heck would I import gas to NJ from, say, Ohio, if there is no additional incentive for me to do that?

Plus, it keeps the supplies of gas, etc., well rationed. People buy only what they really need when the prices are really high (driven up by high demand and low supply). That way, the first ten people coming into the store won't buy up all the water bottles, leaving the rest with nothing.

Meanwhile, a few black-market gas stations have sprung up. Just like in the Soviet Union, where they sold sausages and electronics on the black market at the market price (plus a little extra for the risk), while in the stores the shelves were empty from over-consumption and under-production. As the crazy mathematician from Jurassic Park said, "nature finds the way".

Yes, I know, all that greedy business owners care about is profit. But profit allows the goods to go where they are supposed to and serves as an indicator that the producer is doing the right thing.

Here is a good image from the Facebook:

Appearances deceive

The picture above is a good illustration of the concept that unless you know the deep meaning and context of a situation, you may misunderstand it. For most people in the West, this picture looks very strange: a few officially-dressed men staring intensely and what looks like a bunch of pebbles lying on a block of wood. In fact, of course, these are top players of the deep strategic board game of Go analyzing a situation.

The same goes for frum Jews in general and Chabad in particular. 99% of people (Jews and non-Jews) think that Chabad is just a very large soup kitchen with missionary inclinations. In reality, Chabad is all about making this world into a dwelling for its Creator. The soup kitchen is just one way to achieve this.

The British are coming

Robert Murphy comments on Facebook:

Now people are arguing with me about whether the government has plans on how it would implement martial law, if it had to. Of *course* they have such plans. They developed a plan for taking out Great Britain. That's what these people think their *job* is. Don't you people watch movies?

War Plan Red

My thoughts:

There was once a point when having heard something conspiracy-like about USA being an evil empire (whether from crazy American liberals or Russians or Soviet books), I would roll my eyes. "Sure, it's not perfect, but..."

Then came a point when I realized that all those cynical things being said about the USA being a wannabe policeman of the world for the purpose of fulfilling the interests of a few major corporations may not be so crazy after all.

I guess I have passed that point by now. When I read about US having had a secret plan of fighting the British Empire, I am not even surprised...

I mean, look at these. There is a Russian obscene joke about a little boy looking through a keyhole into his parents' bedroom and exclaiming: "And they tell me not to pick my nose!" American presidents talk about international threats to peace, while USA probably at this point has a contingency plan of taking over the moon.

Martial law? Meh...

Is price gouging evil?

A really nice article about how price gouging in extreme situations plays an important social role. (And making price gouging illegal does the opposite.)

Simply put, price gouging separates luxuries from necessities. imagine someone raises the price for a bag of ice from $4 to $15. Now, the first few lucky people coming into the store aren't going to buy up 10 bags each (leaving the rest of the people who need bags with empty hands). They will think: 'Do we really need so many bags?'

Even for each individual bag, each person will ask: 'Do I simply need it as a luxury, or do I have something really important I am trying to keep on ice?'

The people for whom it's really important will pay the $15 for a bag. The people for whom it's merely a luxury (e.g., they want to have some vodka on the rocks while they are waiting the storm out) will mumble something about those 'damn capitalist pigs' and go away.

This way the resources are 'rationed' appropriately throughout the society.

As the article mentions, it may be that a given store may set the price too high or too low. Well, that's why there is competition on the market. The stores that set their prices too high will have bags left over (since people will go to their competitors), and people who set their prices too low will be quickly sold out, not getting the 'right' amount of the capital for the merchandise.

If you're interested, read on: 'Price Gouging Saves Lives in a Hurricane'.

On a related topic, if you want to know how speculation can play a positive role in the society, watch this video by Bob Murphy:



P.S. By the way, the fact that New Jersey's governor made a warning against price gouging shows once again that though the Conservatives may talk about being friends of the free market, they are not. And they are as ignorant of how free markets work as the Liberals.

Too much information

I was just reading a quite well-written book about baby brain development: Brain Rules for Baby by John Medina. I like the book for the most part, but this little bit annoyed me:

In the chapter where he talks about relationship between the parents, the author discusses how having frequent fights between the parents is bad for the baby's brain development. In passing, he mentions that epinephrine and cortisol are secreted as a part of the 'fight-or-flight' reflex.

And that's it. He sort of just mentions them and then says that if the brain is 'cooked' in the appropriate set of hormones, it grows up healthy, but if not, then it grows up not as well developed.

I really hate when people do that: mention some facts of physiology or anatomy without explaining their relevance. It smacks of a cheap parlor trick. It's almost as if they were doing that to impress the audience with their knowledge of biology or somehow use the biological 'illustration' to give greater credence to their (often non-biological) argument.

I once saw a textbook of Psychology that had a picture of the map of Vienna at the beginning of the chapter on sexual behavior. The caption under the picture said something like the following: 'Many psychology textbooks have pictures of reproductive organs in the chapters on sexual behavior. The authors of this textbook are not sure what the relevance of those pictures is. That is why we included the map of Vienna — while equally irrelevant, it may be more entertaining.' When I read this caption, I thought it made an excellent point.

I have recently given a talk on the role of DNA methylation in late brain development. I had a slide in which I showed a figure from a study that showed that blocking DNA methylation affected long-term potentiation; I also wrote on the slide that 'a number of genes were upregulated'. My advisor asked me if I was planning to discuss or list those genes. I answered 'no'; I didn't think it was relevant, and the authors of that study had only provided a table of genes without discussing them much themselves. My advisor said: 'In that case, don't mention them at all.'

Again, I thought this was an excellent advice. If you're not going to explain how something fits into the puzzle, don't have it lying around, just for decoration. People have limited attention, and, more importantly, everything thing you say must make a point.

So... how could the author have made a better point with the mentioning of cortisol, etc.? Well, as it turns out, the function of cortisol is to draw glucose from most cells of the body towards muscle cells. Basically, when you see a lion and need to run away from it, your body needs quickly to raise energy 'currency' to supply your muscle cells. Release of cortisol does exactly that. And it makes sense to do that in a short term. As Robert Sapolski (an expert on the biology of stress) once put, 'Run away from the lion first; ovulate later.'

Imagine, however, if this process goes on for days or weeks or months! Your cells being constantly depleted of their energy resources. That will create energy crisis in most tissues of your body (except the muscles) and the long-term effects will be disastrous: the lining of your stomach will develop ulcers, your reproductive system will lose ability to perform well, and your brain cells will suffer damage (first, ability to make plastic changes in connectivity is diminished; next, dendritic complexity is reduced; finally, even cell loss -- the irreversible change -- can take place).

Now, if you think about the developing baby brain undergoing energy crisis, it makes sense that exposure to stress can be detrimental to brain development.

I am sure a writer as talented as John Medina could put the above into fewer words. Then, his mentioning of cortisol and epinephrine would be relevant to the discussion of the baby brain.

False sense of safety

*

The worst invention in the Western Civilization's recent history was a result of Americans' attempt to reduce fatalities from road accidents. They introduced the inflatable airbag into the cars. Now the passengers drive, having a sense of safety.

If I were trying to reduce the accidents, I would put a sharp knife in the middle of the steering wheel. And that would reduce the accidents, because, by G-d, people would be driving carefully now.

-- Hugh Hendry, British hedge funds manager (and a famous critic of the government's attempts to manage the economy)

The point of the above quote is that by creating agencies that manage our safety for us, without our choice, the government makes us less safe. First, the agencies like FDA are extremely inefficient and in general bad at what they're trying to do, as a result of being monopolies. But more severely, they prevent us from caring for our own lives and safety.

As a result, you have attempts at logical arguments that state that without FDA, unsafe drugs and food would fill the markets, because the people wouldn't have anyone watching out for them (while the businesses would of course care more about selling the drugs and not about the safety of their customers). The people who make them cannot imagine that someone might want to care for his own safety, relying (if necessary) on private inspection agencies whose reputation he would keep an eye on.


And I think, in the end, that is the worst result of socialism: it changes the culture. It creates a nation of slaves, of people who are similar to a 30-year-old who lives with his parents and is unable to make a decision himself about his life. (As I have written before, studies show that children who were given some small allowances and allowed to manage their purchases themselves grew up to be more responsible adults.)

This is the worst result of American and European governments' policies. We see this culture of dependent junkies in Greece today. When their government attempts to cut down on spending, they come out to streets and protest, since they are not getting the free pie.

The same thing happened in the Roman Empire: in an attempt to please the public and win popularity, the government created welfare programs, feeding and entertaining the masses for free (the source of the 'bread and circuses' expression). Unfortunately, this could not be sustained forever. In an attempt to pay for the ever-increasing demands of the public, Roman government debased the currency, creating massive economic crisis that spanned the centuries and was one of the reasons for the downfall of the Empire.

In my opinion, unless drastic change of course is undertaken (by the people themselves -- for the government will never change itself for the better), both American and European societies are headed the same way. They will destroy themselves from the inside, degenerating socially, economically, and culturally.

The axis of weevils

It seems that the axis of evil now includes:

Iran
Syria
(Not North Korea)
Venezuela
Some random African countries
Finland
Norway
France
Ireland
Switzerland (they get the money of those who didn't want to pay taxes to US gov't)
New Zealand (now that Peter Jackson is filming another movie, they need no aid)

But, on a serious note, one good thing about the picture above is that the French do not get my tax dollars.
