You are not a number

“Since we do not now have any ways of making computers wise, we ought not now give computers tasks that demand wisdom.”
- Joseph Weizenbaum

There’s a number for everything: the number of steps you take each day, your heart rate, your bank balance. Yet, so often, many of the things that we think are quantifiable are not. This collection of articles looks at a number of those important aspects of life and how amazingly, some of the essential things in your life can't be measured, like how much pain you're in, whether you can accurately taste something, or even how intelligent you are.

These all seem like things we should be able to measure. But in reality, we are often taking educated guesses or using outmoded or even biased ways to measure them.

To start, I would love for you to watch this video by Robert F Kennedy, where he defines what GDP means (gross domestic product). He talks about how this number plays a role in our lives, and how often it is quoted as indicating how well a country is doing, yet in fact, it doesn't measure any of the things that make a country worth living in.

Taste
As I browse my local wine store I often look for suggestions and clues to a good wine to buy. I ask the people in the store, but I also look for labels like the rating from Robert Parker of Wine Spectator magazine or if a bottle has won an award. But it turns out that taste is not something you can quantify in a number even though the rating reviewers give to wine often significantly influence how well that bottle sells.
This fascinating video from Vox shows that regular people and famous wine critics often don’t agree and don’t have a standard at all.

Pain
Back pain, shoulder pain--most people will feel these at some point in their lives, but how much pain will each of us feel? Though it seems like an essential measurement, it turns out there’s no way to measure pain. How do doctors know which patients to treat first or how severe an injury is if they can only rely on a subjective measure? These articles look more closely at pain and quantify this most elusive and vital part of human health.

“Right now, there's no clinically acceptable way to measure pain and other emotions other than to ask a person how they feel,” Tor Wager, lead study author and associate professor of psychology and neuroscience at CU-Boulder

Measuring pain how much does it hurt


Brain activity
An electrical impulse travels around your brain and activates different parts of your brain, and lets you perform amazing feats. That sounds about right. Still, it turns out that the fMRI—the technology to measure brain activity—has not been working all this time. This article shows that instead of measuring actual brain activity, the fMRI uses blood flow around the brain as a proxy, and it turns out that assuming that connection was not necessarily the best choice.

“This is likely because fMRIs don’t measure brain activity directly: They measure blood flow to regions of the brain, which is used as a proxy for brain activity because neurons in those regions are presumably more active. Blood flow levels change. “The correlation between one scan and a second is not even fair; it’s poor,” says lead author Ahmad Hariri, a professor of neuroscience and psychology at Duke University.”

“The researchers reexamined 56 peer-reviewed, published papers that conducted 90 fMRI experiments, some by leaders in the field and also looked at the results of so-called “test/retest” fMRIs, where 65 subjects were asked to do the same tasks months apart. They found that of seven measures of brain function, none had consistent readings.”

Intelligence
In Steven J. Gould’s enlightening book The Mismeasure of Man, he looks at the long and sordid history of intelligence tests and in particular, the IQ test. Even its founder Alfred Binet disowned it, and the methods and the systems it uses are both deeply rooted in a racist and misogynistic view of the world. Yet to this day, people proudly quote their IQ score and talk about Mensa membership with great pride, while the entire IQ system is based on bad science and insufficient data.

“Not only did Binet decline to label IQ as inborn intelligence; he also refused to regard it as a general device for ranking all pupils according to mental worth. He devised his scale only for the limited purpose of his commission by the ministry of education: as a practical guide for identifying children whose poor performance indicated a need for special education—those who we would today call learning disabled or mildly retarded.”
In this article in The Independent, another set of research comes to the same conclusion.

“We already know that, from a scientific point of view, the notion of race is meaningless. Genetic differences do not map to traditional measurements of skin color, hair type, body proportions, and skull measurements. Now we have shown that IQ is meaningless too."
IQ tests are 'fundamentally flawed'

Numbers and measurement are valuable tools, but that’s all they are. Truth is far harder to come by and requires a much deeper inquiry. Yet, in our fast-paced world, we sometimes settle for numbers alone because they provide a quick and efficient--yet too often incomplete--answer to many of our essential questions.
