The Living Force
I have been recently reading "Thinking, Fast and Slow" by Daniel Kahneman. In the book (I have only read a few chapters so far) the author has developed ideas put forward in the "Adaptive Unconscious". Here are some snippets that I have gathered so far.
DK describes mental life by the metaphor of two agents called System1 and System2. System1 is the adaptive unconscious which produces fast thinking and System2 is conscious and produces slow, deliberate thinking. By his definition
[quote author=Thinking, Fast and Slow]
System1 operates automatically and quickly, with little or no effort and no sense of voluntary control.
System2 allocates attention to the effortfull mental activities that demand it, including complex computations. The operations of System2 are often associated with the subjective experience of agency, choice and concentration.
.....................
In rough order of complexity, here are some examples of the automatic activities that are attributed to System1
* Detect that one object is more distant than another
* Orient to the source of a sudden sound
* Complete the phrase "bread and ...."
* Make a "disgust face" when shown a horrible picture
* Detect hostility in a voice
* Answer to 2+2=?
* Read words on large billboards
* Drive a car on an empty road
* Find a strong move in chess (if you are a chess master)
* Understand simple sentences
* Recognize that a "meek and tidy soul with a passion for detail" resembles an occupational stereotype
..........
Some skills, such as finding strong chess moves, are acquired only by specialized experts. Others are widely shared. Detecting the similarity of a personality sketch to an occupational stereotype requires broad knowledge of the language and the culture, which most of us possess. The knowledge is stored in memory and accessed without intention and without effort.
Several of the mental actions in the list are completely involuntary. You cannot refrain from understanding simple sentences in your own language or from orienting to a loud unexpected sound, nor can you prevent yourself from knowing that 2+2=4 or from thinking of Paris when the capital of France is mentioned. Other activities, like chewing, are susceptible to voluntary control but normally run on automatic pilot. The control of attention is shared by the two systems. Orienting to a loud sound is normally an involuntary operation of System1, which immediately mobilizes the voluntary attention of System2. You may be able to resist turning toward the source of a loud and offensive comment at a crowded party, but even if your head does not move, your attention is initially directed to it, at least for a while. However, attention can be moved away from an unwanted focus, primarily by focusing intently on another target.
The highly diverse operations of System2 have one feature in common: they require attention and are disrupted when attention is drawn away. Here are some examples:
* Brace for the starter gun in a race
* Focus attention on the clowns in the circus
* Focus on the voice of a particular person in a crowded and noisy room
* Look for a woman with white hair
* Search memory to identify a surprising sound
* Maintain a faster walking speed than is natural for you
* Monitor the appropriateness of your behavior in a social situation
* Count the occurrences of the letter a in a page of text.
* Tell someone your phone number
* Park in a narrow space (for most people except garage attendants)
* Compare two washing machines for overall value
* Fill out a tax form
* Check the validity of a complex logical argument
In all these situations you must pay attention, and you will perform less well or not at all, if you are not ready or if your attention is directed inappropriately.

Usually, System1 runs automatically and System2 is in a comfortable low-effort mode.
[quote author=Thinking, Fast And Slow]
System1 continuously generates suggestions for System2: impressions, intuitions, intentions and feelings. If endorsed by System2, impressions and intuitions turn into beliefs, and impulses turn into voluntary actions. When all goes smoothly, which is most of the time, System2 adopts the suggestions of System1 with little or no modification. You generally believe your impressions and act on your desires, and that is fine - usually.
When System1 runs into difficulty, it calls on System2 to support more detailed and specific processing that may solve the problem of the moment. System2 is mobilized when a question arises for which System1 does not offer an answer, as probably happened to you when you encountered the multiplication problem 17X24. You can also feel a surge of conscious attention when you are surprised. System2 is activated when an event is detected that violates the model of the world that System1 maintains.
..............................
The defining feature of System2, is that its operations are effortful, and one of its main characteristics is laziness, a reluctance to invest more effort than is strictly necessary. As a consequence, the thoughts and actions that System2 believes it has chosen are often guided by the figure at the center of the story, System1.

The above dynamics is well covered by Gurdjieff. He had mentioned the laziness of the intellectual center
[quote author=ISOTM]
The inclination to daydream is due partly to the laziness of the thinking center, that is, its attempts to avoid the efforts connected with work directed towards a definite aim and going in a definite direction.....

and the necessity of shocks (which surprise us) to help us wake up.
System1 offers ready answers to problems. This reminded me of G's description of the formatory apparatus as a sort of secretary.
Consider the simple puzzle
If a ball and bat together cost $1.10 and the bat costs $1 more than the ball, how much does the ball cost?
You can note the first answer that springs to your mind and then check the answer later to see if it is correct. DK states that more than 50% of university students at ivy league schools like Harvard, MIT and Princeton gave the intuitive and incorrect answer (10 cents) . At less selective universities, "the rate of demonstratable failure to check was in excess of 80%". The students were obviously quite capable of figuring out this simple problem - but the author notes that " this is our first encounter with the observation that many people are overconfident, prone to place too much faith in their intuitions".
A couple of others
* If it takes 5 machines 5 minutes to make 5 widgets, how long will it take 100 machines to make 100 widgets?
a) 100 minutes
b) 5 minutes
* In a lake there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
a) 24 days
b) 47 days
And such errors are not limited to simple puzzles either. DK sites the example of an executive at a large financial firm who told him that he had invested tens of millions of dollars in the stock of Ford Motor Company. When asked about how he made the decision, he replied that he had recently attended an automobile show and had been impressed. "Boy, do they know how to make a car!" was his explanation.
[quote author=Thinking, Fast And Slow]
When the question is difficult and a skilled solution is not available, intuition still has a shot: an answer can come to mind quickly - but it is not an answer to the original question. The question that the executive faced (should I invest in Ford stock?) was difficult, but the answer to an easier and related question (do I like Ford cars?) came readily to his mind and determined his choice. This is the essence of intuitive heuristics: when faced with a difficult question, we often answer an easier one instead, usually without noticing the substitution.
[/quote]
The author talks about visual illusions like the Muller-Lyer illusion - another example of a System1 answer being wrong. He says that even after making the measurement and finding out that the lines are equal, we still "see" the lines as not being equal. System1 input cannot be shut down but can be overridden. In this context, he talks about a different illusion - the illusion of thought or cognitive illusions. Here is an interesting tidbit
[quote author=Thinking, Fast And Slow]
As a graduate student, I attended some courses on the art and science of psychotherapy. During one of these lectures, our teacher imparted a morsel of clinical wisdom. This is what he told us : "You will from time to time meet a patient who shares a disturbing tale of multiple mistakes in his previous treatment. He has been seen by several clinicians, and all failed him. The patient can lucidly describe how his therapists misunderstood him, but he has quickly perceived that you are different. You share the same feeling, are convinced that you understand him, and will be able to help." At this point my teacher raised his voice as he said, "Do not even think of taking on this patient! Throw him out of the office! He is most likely a psychopath and you will not be able to help him."
Many years later I learned that the teacher had warned us against psychopathic charm, and the leading authority in the study of psychopathy confirmed that the teacher's advice was sound. The analogy to the Muller-Lyer illusion is close. What we were being taught was not how to feel about that patient. Our teacher took it for granted that the sympathy we would feel for the patient would not be under our control; it would arise from System1. Furthermore, we were not being taught to be generally suspicious of our feelings about patients. We were told that a strong attraction to a patient with a repeated history of failed treatment is a danger sign - like the fins on the parallel lines. It is an illusion - a cognitive illusion - and I (System2) was taught how to recognize it and advised not to believe it or act on it.
The question that is most often asked about cognitive illusions is whether they can be overcome. The message of these examples are not encouraging. Because System1 operates automatically and cannot be turned off at will, errors of intuitive thought are often difficult to prevent. Biases cannot always be avoided, because System2 may have no clue to the error. Even when cues to likely errors are available, errors can be prevented only by the enhanced monitoring and effortful activity of System2. As a way to live our lives however, continuous vigilance is not necessarily good, and it is certainly impractical. Constantly questioning our own thinking would be impossibly tedious, and System2 is much too slow and inefficient to serve as a substitute for System1 in making routine decisions. The best we can do is a compromise: learn to recognize situations in which mistakes are likely and try harder to avoid significant mistakes when the stakes are high. The premise of this book is that it is easier to recognize other people's mistakes than our own.

which underscores the value of networking. Also relevant is the capability of System2 to adopt "task sets" that is it can program memory to obey an instruction that overrides habitual responses.
In a related context, it is interesting to note what the author has to say regarding positive emotions and "cognitive ease". Cognitive ease is the state where System2 is not over-burdened. There are interesting experiments which are cited which demonstrate physiological correlates accompanying cognitive strain (dilated pupils is an example). Cognitive ease is characterized by a comfortable feeling of familiarity and/or feeling good and effortless (referred to as the "flow"). It is triggered by repeated experiences (habits again), good moods, primed ideas etc.
[quote author=Thinking, Fast And Slow]
When you are in a state of cognitive ease, you are probably in a good mood, like what you see, believe what you hear, trust your intuitions, and feel that the current situation is comfortably familiar. You are also likely to be relatively casual and superficial in your thinking. When you feel strained, you are more likely to be vigilant and suspicious, invest more effort in what you are doing, feel less comfortable, and make fewer errors, but you are also less intuitive and creative than usual.
..............
The impression of familiarity is produced by System1, and System2 relies on that impression for a true/false judgment.
The lesson .. is that predictable illusions inevitably occur if a judgment is based on an impression of cognitive ease or strain. Anything that makes it easier for the associative machine to run smoothly will also bias beliefs. A reliable way to make people believe in falsehoods is frequent repetition, because familiarity is not easily distinguished from truth . Authoritarian institutions and marketers have always known this fact.
....................
Good mood, intuition, creativity, gullibility and increased reliance on System1 form a cluster. At the other pole, sadness, vigilance, suspicion, an analytic approach, and increased effort also go together. A happy mood loosens the control of System2 over performance: people become more intuitive and more creative but also less vigilant and more prone to logical errors.
[/quote]
Such connections make biological sense since familiarity signals that the environment is safe and danger is low so that mood is improved and one lets the guard down so to speak. Personally, I have seen the truth of the above statements borne out in many instances of life experience.
Interestingly, James Pennebaker, the social psychologist involved with the study of the effect of writing exercizes on trauma referenced by Timothy Wilson in "Redirect" had this to report from computerized analysis of people's writings.
[quote author=Pennebaker in "The Secret Life Of Pronouns"]
When events happen to us that cause us to feel sad or angry, we tend to try to understand why they occurred. We use cognitive words that reflect causal thinking and self-reflection. Not true for positive emotions such as pride and love. When happy and content, most of us are satisfied to let the joy wash over us without introspection. In other words, negative feelings make us thoughtful; positive emotions make us blissfully stupid.

As Wilson stated in "Adaptive Unconscious", feeling good and being accurate are often at odds with each other.
