Tell me that somebody stopped the war

An interesting point of clash between Daniel "dsquared" Davies and Chris "Stumbling & Mumbling" Dillow lies in their attitude to Tony Blair and the Iraq War, Chris says:

Those protestors outside the Chilcot enquiry on Friday [...] accuse Blair of lying, as if this is a bad thing. Surely, what matters is the allegation that the war was a bad idea badly executed. This stands or falls independently of the question of Blair’s honesty.
Instead, there seems to be a huge premium upon sincerity; Blair himself exploited this when he famously claimed that he was “a pretty straight kind of guy.”


Daniel Davies, in his classic "One Minute MBA" argues that when a project needs to be lied about in order to get it implemented, that is a fairly strong indicator that the project is a bad one:

Good ideas do not need lots of lies told about them in order to gain public acceptance.


So I'm not sure Chris' point about the overvaluation of sincerity stands. Sincerity is generally valuable in political leaders (perhaps because it is so rare?). So those protesters were accusing Blair of lying, because lying by politicians is a bad thing, and (as Iraq shows) a potentially very destructive thing.

But this raises an interesting question: are there circumstances under which it is *necessary and advisable* for political leaders to tell lies?

I would be inclined to say that there never are. Things can justifiably be kept *secret* because the state is often privy to information that could, if broadcast, breach the individual privacy[1] of private citizens, or cause negative effects like mass panic, or even undermine the efficacy of policy (e.g. interest rate changes), but when it comes to actually broadcasting data that governments know to be false, I can't see any justification that isn't based around the interests of the individuals that make up states and governments, rather than the interests of society as a whole.

So pointing out that Blair lied[2] is in fact very relevant to the allegation that the war was a bad idea badly executed.

[1]: I would say the state as an entity should have no right to privacy, as it is not a person.

[2]: On which subject, Davies notes that:

"the difference between "making a definite single false claim with provable intent to deceive" and "creating a very false impression and allowing it to remain without correcting it" is not one that you should rely upon to keep you out of jail."

Procrastination and Anticrastination

An interesting study here concerning procrastination:

The findings, reported in Psychological Science, a journal of the Association for Psychological Science, were very clear.

Even though all of the students were being paid upon completion, those who thought about the questions abstractly were much more likely to procrastinate--and in fact some never got around to the assignment at all.

By contrast, those who were focused on the how, when and where of doing the task e-mailed their responses much sooner, suggesting that they hopped right on the assignment rather than delaying it.

The authors note that "merely thinking about the task in more concrete, specific terms makes it feel like it should be completed sooner and thus reducing procrastination."

They conclude that these results have important implications for teachers and managers who may want their students and employees starting on projects sooner. In addition, these findings are also relevant for those of us resolving to have better time management skills in the New Year!

This idea of focusing on the real and specific rather than the abstract and general is similar to the ideas of productivity guru David Allen, detailed in this profile in Wired:

Items on next-action lists should be described as concretely as possible. Breaking down stuff into physical actions, Allen says, is the key to getting things done.

I've certainly found Allen's ideas useful in getting things done. I now keep a diary and focus on doing things now rather than later.

Living the good life elegantly

One of the ideas Nassim Nicholas Taleb comes back to again and again, both in The Black Swan and Fooled by Randomness is that you can and should live elegantly.

Living elegantly means being stoical about loss and disaster, and not working too hard or becoming overly stressed when things don’t go your way.

It also means avoiding “noise.” In this context noise is the constant humdrum flow of news and factoids that we all expose ourselves to in this information-saturated age. Reading the paper every morning doesn’t make you any more informed than someone who spends their time reading philosophy and history textbooks.

Taleb argues that the older something is the more likely it is to be of value: things that aren’t valuable tend not to be preserved or sustained in culture. This leads to an interesting comment on religion: whyever people believe in god is beside the point, millions of people do and have believed in God for thousands of years so there must be some psychological or cultural value to it. I’m inclined to agree with this, but not with the general point that “because we’ve always done it” is a good argument in favour of anything.

My objection is to the imposition of religious cultural values on those who do not believe: particularly the recent complaint to the ASA that the atheist bus is "offensive."

Stephen Green, national director of Christian Voice, sez:

"There is plenty of evidence for God, from people's personal experience, to the complexity, interdependence, beauty and design of the natural world.

"But there is scant evidence on the other side, so I think the advertisers are really going to struggle to show their claim is not an exaggeration or inaccurate, as the ASA code puts it."

Taleb would of course point out that you can't prove a negative ("God does not exist") and I would point out that the atheist bus does not claim to: "There is probably no God."

This statement is induced partly from lack of any indication of the existence of God so far (based on repeatable experiment, rather than subjective experience) and deduced from the internal inconsistency of most conceptions of God.

In The Black Swan Taleb presents a strong finding from cognitive psychology called the information bias that shows that being exposed to information more frequently does not necessarily improve your ability to make decisions.

Taleb also argues that being presented with a constant barrage of negative news is also bad for you from the point of view of happiness.

I’d like to draw a link between what Taleb says and the ideas of the Viridian design philosophy. In Bruce Sterling’s last note he says that people should minimise the amount of badly-designed clutter in their lives so that they might be happier. In the same way Taleb is advocating a reduction in information clutter, and concentrating on quality rather than quantity of data.

Thoughts on "The Black Swan"

Having read "The Black Swan" by Nassim Nicholas Taleb (his website is here) I have come to a few conclusions:

  1. I spend too much time reading newspapers and on trivial and timewasting exercising (writing this blog post does not qualify as it counts as practice in writing and helps me organise my thoughts).
  2. Much of what I believe about the world isn't based on any kind of objective reality, but rather a collection of superstitions, cognitive biases[link], and predjudices.
  3. In certain non-empirical fields there is little value in deferring to experts if your intention is to accomplish something (like building a bridge, or making money).
  4. The value in the "free market" has less to do with competition and more to do with the resultant levels of "stochastic tinkering" that have the potential to lead to hugely influential but unpredicted developments.

The Book Itself

Taleb is arrogant, irreverent and amusing - all qualities I value in anyone. He writes engagingly, occasionally dipping into anecdote (for illustrative purposes, not necessarily to support his argument).

The Black Swan

A Black Swan is an unpredicted event that has a huge impact. Human beings tend to ignore Black Swan events when making decisions about the future, despite the fact that Black Swans tend to have an overwhelming effect in history, science, business, finance, and individual lives.

Black Swan events are outliers, they have an extreme impact, and third human nature has the tendency to attempt to "explain" the Black Swan after the fact, making it seem predictable and obvious.

Extremistan and Mediocristan

Taleb defines two areas of human experience: in Mediocristan things tend to behave in a fairly orderly and predictable manner. The distributions of height in a large population, for example, remain relatively close to a normal Gaussian bell curve even if you were to add the world's tallest man to the population - because he is not 3 kilometres tall he does not effect the overall distribution.

In Extremistan, on the other hand, outliers have a disproportionately large effect. The distributions of personal net worth in a large population, for example, will be completely thrown out of whack if you add Bill Gates to the population.

Power Laws and Guassian Bell Curves

In Extremistan, power laws (Pareto's Principle, Zipf's Law) and fractal relationships are the norm. In Mediocristan Guassian bell curves are the norm.

Taleb believes the bell curve is misused in it's application in investing (I wasn't aware the bell curve was used extensively in finance).

Scalable and Non-Scalable Professions

Inequality tends to follow a power law. The richest 1% own 50% of all assets, whereas the poorest 10% own substantially less than 10% of all assets.

With regard to income some professions lend themselves to black swans and power laws, and others don't. Medical doctors and priests will tend to earn roughly a certain amount, which will fall somewhere on the bell curve of income for that particular profession.

Writers, venture capitalists, entrepreneurs, and scientists, on the other hand, all occupy extremistan, or black swan territory. Some writers (like J.K. Rowling or Terry Pratchet) earn collossal amounts of money per hour worked whereas the vast majority will struggle to earn anything.

Empiricism and the Problem of Induction

How do we know that what happens in the past will continue to happen in the future? Taleb likes empirical philosophers like Francis Bacon and Karl Popper, and Sextus the Empirical. In trying to find knowledge about the world it is better to prove conclusively that something doesn't work than that it does - in fact you can't prove that something always works.

Knowledge, therefore, emerges from negatives. Disproving something adds to knowledge.

Platonism and Theories

Taleb rails against creating a theory and then selecting evidence to fit the theory. He dislikes the application of game theory to economics, and portfolio theory to investment. He describes the mistake of focusing on elegant, tractable mathematics at the expense of empirical knowledge as platonicity, and any knowledge divined from such abstract mathematical theorising is "nerd knowledge."

Cognitive Bias and the Narrative Fallacy

Correlation does not equal causation. Post hoc ergo propter hoc.

Terry Pratchett and Taleb

Pratchett comments extensively on the human desire to create stories (the Discworld is a world that runs on narrative, rather than physical laws) and on the fact that million-to-one chances occure nine times out of ten.

Also Pratchett's uber-politician Lord Vetinari is the embodiment of the knowledge that in an unpredictable world what people really, really want is for tomorrow to be pretty much the same as today.

Arthur Koestler and Taleb

Skimming through The Sleepwalkers by Arthur Koestler (which I have read) I can see many parallels between Taleb's dislike of platonism and Koestler's similar criticism of excessive theorising in physics.

Taleb refers to Koestler's book in The Black Swan in the context of the inadvertant nature of much scientific discovery.

Koestler was also intensely critical of the dogmatic nature of theoretical physics (as he perceived it). Koestler's problem was that, unlike classical physics, quantum electrodynamics involved fields and quanta that could be one or the other or something else, depending on your perspective. I personally think the problem is more to do with the fact that QED is counter-intuitive. We humans have evolved in a quasi-classical environment and just aren't set up for thinking in terms of the quantum environment of the very small.

Hayek and Stochastic Tinkering

Taleb believes the value in free markets lies in their ability to generate new idea in a process of stochastic tinkering. This apparently is what Hayek thought.

Taleb is also a fan of Francis Bacon and Karl Popper. Does not like Platonism - mistaking the map for the territory and overextending the use of models.

Whither singularity?

Both Kurzweil and Taleb are obsessed with the fact that humans tend to have an "intuitive-linear perspective."

Taleb doesn't comment on the singularity directly. He does refer to the importance of power laws and such.

Conclusions

There is a lot of food for thought in this book, and I intend to read a lot more about the various topics that Taleb raises.

As ever at this stage in my education any new knowledge raises more questions and than it answers.

However as Taleb's central point is that the world is in many ways fundamentally unknowable and unpredictable perhaps this is a good thing.

The objective of learning is not simply to know a load of facts, but rather to become comfortable with the limits of your understanding. To transform unknown unknowns into known unknowns and to cope as best you can with those things that remain unknown unknowns.

...or were you looking at the Woman in the Red Dress?



Researchers have discovered that the colour red enhances men's attraction towards women:

the women shown framed by or wearing red were rated significantly more attractive and sexually desirable by men than the exact same women shown with other colors. When wearing red, the woman was also more likely to score an invitation to the prom and to be treated to a more expensive outing.

Apparently this will have implications for dating and product design, but I think that they've already been taken on board in these contexts.
