        Does The PSB still read the motd? This reminds me of the racheting
        effect you talk about (for the skilled here). -ausman
        \_ 80% of participants had evaluated themselves as being above the average driver
        \_ this effect is common in mega corporations
        \- ausman: i dont really check in here any more ... at some point
           the repeated self-inflected wounds dropped the wall-mass below
           some critical threshold for me.
           but on your topic, did you see this long EMORRIS article from
           the NYT a while back:
           http://opinionator.blogs.nytimes.com/2010/06/20/the-anosognosics-dilemma-1
           \_ Yeah, I am not talking about the inability to see ones own
              shortcomings, rather the other side of the coin, the inability to
              recognize ones own unusual competence.
              shortcomings, rather the other side of the coin, the tendency
              to discount ones own unusual competence, eg things are either
              "hard" (if you don't understand) or "trivial" (once you do).

5/7     had 3 interviews (over 2 days) that all went well but didn't
        get an offer. I've heard its totally normal and acceptable to
        ask for feedback and/or "what went wrong" or "why didn't I
        get an offer". Is that really true? How should I approach this?
        ask one of the tech people I spoke to? or the recruiter (who
        seems generally unknowledgeable but maybe in a better position

5/7    (I am revising my numbers, in my fit of rage at 4am in the morn,
        I made some math errors I didn't feel like correcting.  anyway...)
        I work at a year old startup, 50 employees, pre-IPO (duh!), exit
        strategy is to either become profitable company or get bought,
        almost profitable but not quite, fast paced, lots of work,

1/22    Layoffs at Microsoft, Intel, IBM.  See, this is part of the problem
        with deflation amid a recession.  When prices crater, companies'
        revenue decreases and people get layoffs.
        \_ Poll: If you're the CEO, would you try to lay off a large
           percentage of your workers, or would you implement changes
           like mandatory vacation or pay cut? Either case will decrease

illusory superiority, rating their ability as above average, much higher than it actually is, while the highly skilled underrate their own abilities, suffering from illusory inferiority. Actual competence may weaken self-confidence, as competent individuals may falsely assume that others have an equivalent understanding. As Kruger and Dunning conclude, "the miscalibration of the incompetent stems from an error about the self, whereas the miscalibration of the highly competent stems from an error about others" (p. Kruger and Dunning noted earlier studies suggesting that ignorance of standards of performance is behind a great deal of incompetence. This pattern was seen in studies of skills as diverse as reading comprehension, operating a motor vehicle, and playing chess or tennis. Kruger and Dunning proposed that, for a given skill, incompetent people will: 1 tend to overestimate their own level of skill; to a condition in which a person who suffers a physical disability because of brain injury seems unaware of or denies the existence of the disability, even for dramatic impairments such as blindness or paralysis. After being shown their test scores, the subjects were again asked to estimate their own rank, whereupon the competent group accurately estimated their rank, while the incompetent group still overestimated their own rank. As Dunning and Kruger noted, Across four studies, the authors found that participants scoring in the bottom quartile on tests of humor, grammar, and logic grossly overestimated their test performance and ability. percentile, they estimated themselves to be in the 62nd. Meanwhile, people with true ability tended to underestimate their relative competence. Roughly, participants who found tasks to be relatively easy erroneously assumed, to some extent, that the tasks must also be easy for others. A follow-up study, reported in the same paper, suggests that grossly incompetent students improved their ability to estimate their rank after minimal tutoring in the skills they had previously lacked--regardless of the negligible improvement in actual skills. In 2003 Dunning and Joyce Ehrlinger, also of Cornell University, published a study that detailed a shift in people's views of themselves when influenced by external cues. Participants in the study (Cornell University undergraduates) were given tests of their knowledge of geography, some intended to positively affect their self-views, some intended to affect them negatively. Dunning, Kruger, and coauthors' latest paper on this subject comes to qualitatively similar conclusions to their original work, after making some attempt to test alternative explanations. edit Cross-cultural variation Studies on the Dunning-Kruger effect tend to focus on American test subjects. Similar studies on European subjects show marked muting of the effect; studies on some East Asian subjects suggest that something like the opposite of the Dunning-Kruger effect operates on self-assessment and motivation to improve: Regardless of how pervasive the phenomenon is, it is clear from Dunning's and others' work that many Americans, at least sometimes and under some conditions, have a tendency to inflate their worth. It is interesting, therefore, to see the phenomenon's mirror opposite in another culture. "Why the unskilled are unaware: Further explorations of (absent) self-insight among the incompetent" (PDF).

In a section called Offbeat News Stories he found a tantalizingly brief account of a series of bank robberies committed in Pittsburgh the previous year. From there, it was an easy matter to track the case to the Pittsburgh Post-Gazette, specifically to an article by Michael A Fuoco: ARREST IN BANK ROBBERY, SUSPECT'S TV PICTURE SPURS TIPS At 5 feet 6 inches and about 270 pounds, bank robbery suspect McArthur Wheeler isn't the type of person who fades into the woodwork. So it was no surprise that he was recognized by informants, who tipped detectives to his whereabouts after his picture was telecast Wednesday night during the Pittsburgh Crime Stoppers Inc. Wheeler had walked into two Pittsburgh banks and attempted to rob them in broad daylight. What made the case peculiar is that he made no visible attempt at disguise. There he is with a gun, standing in front of a teller demanding money. Yet, when arrested, Wheeler was completely disbelieving. Apparently, he was under the deeply misguided impression that rubbing one's face with lemon juice rendered it invisible to video cameras. In a follow-up article, Fuoco spoke to several Pittsburgh police detectives who had been involved in Wheeler's arrest. Commander Ronald Freeman assured Fuoco that Wheeler had not gone into "this thing" blindly but had performed a variety of tests prior to the robbery. Sergeant Wally Long provided additional details -- "although Wheeler reported the lemon juice was burning his face and his eyes, and he was having trouble (seeing) and had to squint, he had tested the theory, and it seemed to work." He had snapped a Polaroid picture of himself and wasn't anywhere to be found in the image. Long tried to come up with an explanation of why there was no image on the Polaroid. or Wheeler had pointed the camera away from his face at the critical moment when he snapped the photo. As Dunning read through the article, a thought washed over him, an epiphany. If Wheeler was too stupid to be a bank robber, perhaps he was also too stupid to know that he was too stupid to be a bank robber -- that is, his stupidity protected him from an awareness of his own stupidity. Dunning wondered whether it was possible to measure one's self-assessed level of competence against something a little more objective -- say, actual competence. Within weeks, he and his graduate student, Justin Kruger, had organized a program of research. Their paper, "Unskilled and Unaware of It: How Difficulties of Recognizing One's Own Incompetence Lead to Inflated Self-assessments," was published in 1999. Dunning and Kruger argued in their paper, "When people are incompetent in the strategies they adopt to achieve success and satisfaction, they suffer a dual burden: Not only do they reach erroneous conclusions and make unfortunate choices, but their incompetence robs them of the ability to realize it. Instead, like Mr Wheeler, they are left with the erroneous impression they are doing just fine." It became known as the Dunning-Kruger Effect -- our incompetence masks our ability to recognize our incompetence. In search of more details, I called David Dunning at his offices at Cornell: DAVID DUNNING: Well, my specialty is decision-making. How well do people make the decisions they have to make in life? And I became very interested in judgments about the self, simply because, well, people tend to say things, whether it be in everyday life or in the lab, that just couldn't possibly be true. Not just that people said these positive things about themselves, but they really, really believed them. Which led to my observation: if you're incompetent, you can't know you're incompetent. DAVID DUNNING: If you knew it, you'd say, "Wait a minute. But when you're incompetent, the skills you need to produce a right answer are exactly the skills you need to recognize what a right answer is. In logical reasoning, in parenting, in management, problem solving, the skills you use to produce the right answer are exactly the same skills you use to evaluate the answer. And so we went on to see if this could possibly be true in many other areas. DAVID DUNNING: If you look at our 1999 article, we measured skills where we had the right answers. And our test-subjects were all college students doing college student-type things. Presumably, they also should know whether or not they're getting the right answers. And yet, we had these students who were doing badly in grammar, who didn't know they were doing badly in grammar. We believed that they should know they were doing badly, and when they didn't, that really surprised us. ERROL MORRIS: The students that were unaware they were doing badly -- in what sense? DAVID DUNNING: There have been many psychological studies that tell us what we see and what we hear is shaped by our preferences, our wishes, our fears, our desires and so forth. But the Dunning-Kruger effect suggests that there is a problem beyond that. Even if you are just the most honest, impartial person that you could be, you would still have a problem -- namely, when your knowledge or expertise is imperfect, you really don't know it. Is this supposedly the hallmark of an intelligent person? It's knowing that there are things you don't know that you don't know. Donald Rumsfeld gave this speech about "unknown unknowns." It goes something like this: "There are things we know we know about terrorism. And I thought, "That's the smartest and most modest thing I've heard in a year." Rumsfeld's famous "unknown unknowns" quote occurred in a Q&A session at the end of a NATO press conference. All of us in this business read intelligence information. And we read it daily and we think about it, and it becomes in our minds essentially what exists. Rumsfeld's "known unknowns" and "unknown unknowns" seem even less auspicious. Are they like a scotoma, a blind spot in our field of vision that we are unaware of? I kept wondering if Rumsfeld's real problem was with the unknown unknowns; or was it instead some variant of self-deception, thinking that you know something that you don't know. And yet...
