Blinded by the night

there is no sand storm
despite yellow stained rays
creeping up the side of shaky skyscrapers
leaning on poorly built lintels
cracked re-bar exposed
under thick un-mortered walls

So, in the last post I didn't say it explicitly. But here we are, I must... Heisenberg and Bias. Check out the old post, if you haven't yet or if you are new.

Last night was really incredible. Of course I mention how peaceful it has been, and then it explodes. Do I keep my mouth shut now?

I will not speculate on Why or How or Motivations or Timings of the clashes. I admit that my view of Tahrir square is from 10 km away.

The pro-government protesters approached the square where the anti-government protesters have been for the past week. They charged on foot, on horseback, on camels. A lot of things were thrown by both sides, rocks, sticks, "gas bombs" or molitov cocktails. The front between the two groups shifted back and forth, back and forth as they pushed each other. It was impossible to tell who was who. People got onto roofs. Throwing off chairs and other things.

There was a line of 3 trucks that had no drivers. They were used as a front line, a shield for both sides. They were pushed and moved as the tide of the line moved back and forth.

But that was last night... today is today... now is now... and when you are reading this it will be later.

Reputable news agencies in this end of the world keep asking leading questions. Interviewing one side only. Using inflammatory language.

There are 80 million people in this country and probably 80 million sides. I guess they can't get to everybody, but maybe more than one would be nice.

Ego update: Lots of hits on this here humble blog in the past few days. Leave me some comments here! I would love to hear what you like and don't like.

Everywhere there's signs...

Shameless editorial note: Please come back the 15th of October to help me win contest #6.

Don't get the wrong idea from this post. Haiti is not getting back to normal.

It is not being reconstructed. Or deconstructed. Or inducted.
But people live here. And they are living. And to do that, things are constructed.
As this happens, the landscape changes. Shapes of slumped buildings adjust themselves, they become lighter, they become transparent.
Their pieces are laid in neat piles.
It is like wind is blowing around the rubble, the iron bar, the cement.
Shifting desert sands and dust, but a thousand times heavier.

I was in a certain meeting the other day. It lasted two days. It was many things... Many things were said and said again. And again. Somethings were said only once. Some things were brushed aside.

Discussing aspects of worst case scenarios, someone said "...if people build without control."

Life happens, my friend, and it is not controlled.

Walls and roofs and floors are no longer separated. They are being broken up. Piled up. Recycled. They are being built back from blocks that fell.

* * * 
I am not a bleeding heart aid worker. I am not naive (though my father may argue otherwise). I am not one who instantly identifies with a suffering population, believing I can solve their problems because I mistakenly think I understand them and feel their pain.

But I do think it is important to take off those damn yellow glasses and try to see something from another point of view than your own. Forget your own priorities for a second. Just one second, then go back. That's how we might start to get a realistic view of whatever it is we are looking at. It's not that we can ever be inside, really inside, something else; we are outside and will remain so (and there is value in that). But just a quick flip of perspective, upside down, once in a while is good. Question it. Then go back to where you were perched before, with a little clearer view.

Living. Eating. Bathing. Gambling. Carrying on after. Of course people are picking up old blocks and putting them back together. People aren't waiting for the engineers to come. They are not waiting for development projects with seismic retro fitting. They are not waiting for our project frameworks. They are living. And they will continue to do so.

Everyone has an agenda and a bias. I tried to loose my own, but maybe it is easier for me because I do not claim to be an expert on Haiti or reconstruction or normal.

Messages are passed, as in other parts of the world, by taxis - or tap taps.

Many have heartfelt messages of faith (though most are french or creole, here is an english one).
Some are less deep and less meaningful. Most are spelled wrong.

This is my favorite. It is in creole. The driver translated for me (and did some awesome driving so I could catch a photo of it). I understood that it says roughly: "I would be ashamed if I were you."
With Rambo below.
Classic.
Excellent.

Indicators

The answer is 42.
But what does 42 mean, really?

Remember two things: Heisenberg and Bias.

* * *
Dirty old Heisenberg

If you look my way
I might smile or scowl
or curse
depending
on who you might be
friend or foe
or dirty old man.
Even when I seem
to do nothing
know that ignoring you
is a calculated reaction.
* * *
Inherent Bias

We wear yellow glasses. We are looking at a blue world. We see a green world. If we know our glasses are yellow, then hopefully we will remember that the green world we are looking at is actually bluer than that which we see as green.


* * *

The problem of measurement or observation or knowing is not new. Heisenberg was mentioned and there is Schrödinger and his poor cat or the quantum suicide scenario, which are more obtuse discussions about observers and the observed, whose practicality is questionable.  I am a scientist and aid worker, so that’s what’s practical to me.

An interesting and practical discussion about the perspective of being outsider on the Tales From The Hood blog rung true with me in certain situations, but he left something out.  He is right, sometimes an outsider can filter out a local bias, but sometimes an outsider can exaggerate a local bias as well. The important thing is to be aware of one’s effect and one’s biases and the situation and the complex interactions therein. We can never eliminate these things, but we can at least be aware of them.

* * *

Intelligent scientists and aid workers alike know that by measuring something you do indeed affect it. We also know, despite not being quantum physicists, that we will never know the exact value or position or whatever. Whether numbers or simple observations, we are careful to minimize these things by triangulation, awareness and thoughtful measurement methods.

An example: Hydrogeologists poke holes (i.e. dig wells) into aquifers and in doing so disrupt what was once, and in being aware of that, we accept it because it is good enough to understand the system. It is that, in fact, our goal in observing anything: to understand what is going on. 

When we do science in aid work, we are still scientists and indeed report a range of values or other interpretations that reflect uncertainty. The methodology (how these numbers are arrived at) is rigorous and has been peer reviewed, published and duplicated by experts. The documentation of such methodology is available, transparent and clear, even to someone outside the relevant technical field who has basic mathematics background, some curiosity and half a brain.

An example: We measure a certain number of randomly sampled children to represent a greater population which is very specifically defined and say, for example, that for this defined population there is an 80% chance that we are beyond the emergency threshold of global acute malnutrition or that the level of X problem is Y% with a 90% confidence interval of +/-Z.

* * *

On NOT understanding Heisenberg: The danger in science and in aid work is when people do not take the time to understand what a number or observation means: how it was measured, the constraints and limitation inherent in it, some people don’t even know the units associated with that number (e.g. 42). Without some knowledge about the mechanics of the observation, you will never know what anything actually says about the system or population or, really, about anything.

On NOT understanding Bias: This can be your bias (your yellow glasses), as well as the bias of the presentation. The most dangerous and common thing of all is to talk about a number or to compare two numbers that are not related at all and then draw some wide-sweeping conclusions from them. There are many particularly worrying examples of this. Some examples of this are well intentioned but careless, and some straight-up-dirty manipulation of data.

Back to practicality. We make observations to come to conclusions. I hate conclusions. They are usually wrong because they depend on a complexity of things. But alas, conclusions are a necessary evil.

Understanding Heisenberg + Bias = better conclusions. Knowing what the number or observation means helps filter some bias, but can’t get it all. By being aware of bias, and especially the bias of the audience, and by trying to take off or lighten the yellow glasses makes the conclusion stronger, more realistic and inherently better.

* * *
One problem with my argument is that it is too idealistic and simple. Bad science, bad measurements and bad observations are rampent. Which makes pretty much any view of them moot. (But can you expect me to address everything in a single blog post? Really?) And the point is, by using the noggin a little and not just accepting what you read, you can identify this "badness."

Another problem with my argument is that I am guilty too, I sometimes draw conclusions too fast, I have biases, I have a sick sense of humor that gets the best of my biases. But sheesh, I am human. The point is not that I know best, it is that I am thinking about it and you should too.

Did I bore you? Confuse you?
If so, read it again.
If not, enjoy lighter side of indicators.

* * *

In every niche there are standard, quantifiable indicators. For me professionally, this often boils down to things like the prevalence of WASH related diseases, number of people per latrine, liters of water per person per day, fecal coliforms per sample etc. We also have qualitative indicators which may give another, less number-full view of the situation, but equally valuable.

I have come up with a few indicators of my own, which mean nothing, are not scientific and are most undoubtedly influenced by my sick sense of humor and biases. The ones I will present here relate to the level of development of a place, mostly the economic development of that place.

I hoped I didn’t have to say this, but I guess I need a disclaimer: In all seriousness, these are really complicated subjects. Please realize that by presenting these ridiculous indicators, that I am demonstrating exactly the danger of this entire discussion. My apparent hypocrisy is intentional. I am a sarcastic person and I intend to remain that way.

* * *

Fire: And god said let there be light, and it was good. And man discovered fire and flint. And then matches were available on the local market. And then lighters. And then lighters with flashing lights inside. And then lighters with flashing light and a button to make those flashing disco lights be projected onto a close wall or floor.

Beer for your buck: The bigger and cheaper the beer, the more dire the economic situation of the country.  Can the average cost per swig of beer be positively correlated to the average income of a household or somehow be an inverse proxy indicator for GDP? You find big, cheap beers in Congo and Guinea; smaller, expensive beers exported from Europe. Do note that Budweiser has a pretty cheap, twenty-two ounce beer. America is going to shit.

McDonalds for peace: Some people claim that there are fewer wars and less strife in countries with McDonalds. Clearly a chicken-vs-egg argument should ensue, but in my recent history I have lived in countries with relatively high levels of strife and not one had a McDonalds. (Not my own idea, just one I thought was worth sharing.)

Gambling as an indicator of early recovery after displacement:

I see Haiti eight months after the earthquake. Life is not normal here and won’t be for a long time, but it is transitioning back slowly. With this bias, I look for signs of normalcy. I search them out. And I found one. The lottery is up and running, people are gambling again, so one can conclude that this place is getting back to normal.

The lottery kiosks or shacks or buildings are newly painted. They say “BANK – LOTTO- CHEZ TITI.” Other types of kiosks haven’t been repainted, even if they are starting to reopen. Not the water sellers. Not the pharmacies. But indeed the lottery bosses are back in business. Folks are crowded around the blackboards on the walls and doors which are updated twice a day with the winning numbers. A clear early warning indicator of recovery.

So my boss asks, can you assess Maya Camp, where people are re-settling?  How is it there? I visit. I don’t even have to get out of my air-conditioned, white Land Cruiser to draw my conclusion. I see that a Chez Titi kiosk is up and running within the camp and I know that these people are ready to get back to normal. They are doing fine.


* * *

Perhaps I can solicit Paul Collier and his army of ingenious grad students to run an in depth retro-analysis on existing data to check the validity of my new-fangled-sarcastic indicators.

* * *

On inspiration: This post was gourbled out of my head, somewhat, by checking out the aforementioned blog, and in particular his post about Skynard and simplicity, actually many of his posts. Clearly I dig this dude’s style and outlook on aid work. Take some time to check out his posts.

Editorial note added afterwords: Hey number-geeks and aid-workers, here is some interesting questions posed by statiscians dealing with the MGDS. It's a start. (Thanks Trish, for pointing this out to me.)

What was once















What was once upright
rigid brightly painted or gray
is resting
tired
from a violence
absent of aggression

* * *

I can not claim to know what was once. Here.

From one perspective, I gape at walls and floors and ceilings draped over one another. I stand upon, step over fissures in the road. I listen to stories and gasp, knowing that I am only an observer, but not the only observer.  My own perspective quite the same as many, except that I am probably more intent than most on getting a good picture of the fissures in the road to impress my geologist friends.

From another perspective, this event has been measured by standard metrics: Richter, deaths, displacement of people or earth, monetary value of infrastructure destroyed.
 
Heisenberg was right. Absorbing light off the white rubble changes its direction, phase, superposition, tint, interpretation. Putting a number on this scene affects it.

* * *

I have seen the palace and the jail, the cathedral and the bridge. Each of them have split in half and what was once proud is crass.
I did not enter convinced by ghosts and twisted iron bar that locks inside some stories that only come from far.
