Critical Thinking Critically Needed

As a lad I was fortunate to have read  S I Hayakawa’s “Language in Thought and Action.” It was my introduction to Alfred Korzybiski’s General Semantics.  General semantics was my introduction to critical thinking.  He advocated not confusing the “thing” with “its label,” or as he put it “the map is not the territory.”  It appears that Korzybiski’s spirit still lives a David Brooks notes (without mentioning Korzybiski). – carlos

David Brooks’s Blog

The good folks organized a symposium, and 164 thinkers contributed suggestions. John McWhorter, a linguist at Columbia University, wrote that people should be more aware of path dependence. This refers to the notion that often “something that seems normal or inevitable today began with a choice that made sense at a particular time in the past, but survived despite the eclipse of the justification for that choice.”

For instance, typewriters used to jam if people typed too fast, so the manufacturers designed a keyboard that would slow typists. We no longer have typewriters, but we are stuck with the letter arrangements of the qwerty keyboard.

Path dependence explains many linguistic patterns and mental categories, McWhorter continues. Many people worry about the way e-mail seems to degrade writing skills. But there is nothing about e-mail that forbids people from using the literary style of 19th-century letter writers. In the 1960s, language became less formal, and now anybody who uses the old manner is regarded as an eccentric.

Evgeny Morozov, the author of “The Net Delusion,” nominated the Einstellung Effect, the idea that we often try to solve problems by using solutions that worked in the past instead of looking at each situation on its own terms. This effect is especially powerful in foreign affairs, where each new conflict is viewed through the prism of Vietnam or Munich or the cold war or Iraq.

Daniel Kahneman of Princeton University writes about the Focusing Illusion, which holds that “nothing in life is as important as you think it is while you are thinking about it.” He continues: “Education is an important determinant of income — one of the most important — but it is less important than most people think. If everyone had the same education, the inequality of income would be reduced by less than 10 percent. When you focus on education you neglect the myriad of other factors that determine income. The differences of income among people who have the same education are huge.”

Joshua Greene, a philosopher and neuroscientist at Harvard University, has a brilliant entry on Supervenience. Imagine a picture on a computer screen of a dog sitting in a rowboat. It can be described as a picture of a dog, but at a different level it can be described as an arrangement of pixels and colors. The relationship between the two levels is asymmetric. The same image can be displayed at different sizes with different pixels. The high-level properties (dogness) supervene the low-level properties (pixels).

Supervenience, Greene continues, helps explain things like the relationship between science and the humanities. Humanists fear that scientists are taking over their territory and trying to explain everything. But new discoveries about the brain don’t explain Macbeth. The products of the mind supervene the mechanisms of the brain. The humanities can be informed by the cognitive sciences even as they supervene them.

If I were presumptuous enough to nominate a few entries, I’d suggest the Fundamental Attribution Error: Don’t try to explain by character traits behavior that is better explained by context.

I’d also nominate the distinction between emotion and arousal. There’s a general assumption that emotional people are always flying off the handle. That’s not true. We would also say that Emily Dickinson was emotionally astute. As far as I know, she did not go around screaming all the time. It would be useful if we could distinguish between the emotionality of Dickinson and the arousal of the talk-show jock.

Public life would be vastly improved if people relied more on the concept of emergence. Many contributors to the Edge symposium hit on this point.

We often try to understand problems by taking apart and studying their constituent parts. But emergent problems can’t be understood this way. Emergent systems are ones in which many different elements interact. The pattern of interaction then produces a new element that is greater than the sum of the parts, which then exercises a top-down influence on the constituent elements.

Culture is an emergent system. A group of people establishes a pattern of interaction. And once that culture exists, it influences how the individuals in it behave. An economy is an emergent system. So is political polarization, rising health care costs and a bad marriage.

Emergent systems are bottom-up and top-down simultaneously. They have to be studied differently, as wholes and as nested networks of relationships. We still try to address problems like poverty and Islamic extremism by trying to tease out individual causes. We might make more headway if we thought emergently.

We’d certainly be better off if everyone sampled the fabulous Edge symposium, which, like the best in science, is modest and daring all at once.A version of this op-ed appeared in print on March 29, 2011, on page A31 of the New York edition.


About carlos

I'm a curious person, of reasonable intellect, "on the beach" (retired) and enjoying my interest in anthropology, language, civil rights, and a few other areas. I've been a hippie/student/aerospace tech writer in the '60s, a witness to the Portuguese revolution in the ‘70s, a defense test engineer and witness to the Guatemalan genocide in the '80s, and a network engineer for an ISP in the '90s. Now I’m a student and commentator until my time is up. I've spent time under the spell of the Mesoamerican pyramids and the sweet sound of the Portuguese language. I've lived in Europe, traveled in Brazil, Central America, Iceland, New Zealand, and other places. My preferred mode of travel is with a backpack and I eat (almost) anything local. Somehow, many of the countries I have been to have had civil unrest (for which I was not responsible). I'm open to correspond with anyone who might share my liberal, humanist interests. I live in San Buenaventura, California.
