Most things that people want to learn do not resemble language, golf or chess, but rather a game in which the generalist has an advantage. A hostile learning environment

Seemingly inefficient things are productive: expanding your horizons, giving yourself time, switching professions. 

early specialisation is a good idea if you want to become successful in certain fields, sports or professions. In fact, in some cases, it’s the only option. Take chess, for example: if you don’t start early, you won’t stand a chance at glory.

learning chess is not a good model for learning other things. Epstein explains this using the work of psychologist Robin Hogarth, who makes the distinction between friendly (kind) and unfriendly or hostile (wicked) learning environments.

In a friendly learning environment, such as chess, the rules are clear, the information is complete (all pieces are visible on the board), and you can (ultimately) determine the quality of every move. In other words, the feedback loop

friendly learning environments are the exception. The world is not as clear-cut as golf or chess. So early specialisation is often a bad idea. 

In hostile learning environments without repetitive patterns, mastery is much harder to achieve. The feedback loop is insidious. Unlike chess, experience does not necessarily make you better. You may stick with the wrong approach because you’re convinced it’s the right one. 

The better a teacher scored on their own subject (i.e., the higher the grades their students got in that subject), the more mediocre students’ scores were across the complete programme (all modules). The explanation? Those teachers gave their students rigidly defined education, purely focused on passing exams. The students passed their tests with high marks – and rated their teachers highly in surveys – but would fail later on. 

In learning environments without repetitive patterns, where cause and effect are not always clear, early specialisation and spending countless hours does not guarantee success. Quite the opposite, Epstein argues. Generalists have the advantage: they have a wider range of experiences and a greater ability to associate and improvise. (The world has more in common with jazz than classical music, Epstein explains in a chapter on music.)

Many modern professions aren’t so much about applying specific solutions than they are about recognising the nature of a problem, and only then coming up with an approach. That becomes possible when you learn to see analogies with other fields, according to psychologist Dedre Gentner, who has made this subject her life’s work.

Another advantage generalists and late specialists have is more concrete: you are more likely to pick a suitable study, sport or profession if you first orient yourself broadly before you make a choice.

Greater enjoyment of the game is one of the benefits associated with late specialisation, along with fewer injuries and more creativity.

which child, teenager or person in their 20s knows what they will be doing for the rest of their lives?

Persevering along a chosen path can also lead to other problems: frustrations about failure. If practice makes perfect, why am I not a genius? In a critical review,

The tricky thing about generalist long-term thinking versus specialist short-term thinking is that the latter produces faster and more visible results.

specialising in short-term success gets in the way of long-term success. This also applies to education.

(Another example: the on-going worry about whether or not students’ degree choices are "labour market relevant".)

Teachers who taught more broadly – who did not teach students readymade "prescribed lessons” but instilled "principles" – were not rated as highly in their own subject, but had the most sustainable effect on learning. However, this was not reflected in the results. These teachers were awarded – logically but tragically – lower ratings by their students.

the 10,000 hour gang has considerable power with their message "quitters never win, winners never quit".Epstein’s more wholesome message seems weak and boring in comparison. Some things are simply not meant for everyone, doubt is understandable and even meaningful, you can give up and change your choice of work, sports or hobby, and an early lead can actually be a structural disadvantage. 

"Don’t feel behind." Don’t worry if others seem to be moving faster, harder or better. Winners often quit.

It's one thing to be closed to students' arguments or to insist on conformity with a prof's views.  It is another altogether when students do not know how to argue their own points, especially points that are not political.  At some point, isn't it the case that the prof does know even a little bit more about their subjects than their students?

Several studies (post 1998) seem to indicate that the capacity to understand and engage in logical argumentation has diminished (at least in the 'Western' world). These studies seem to have encouraged the state education boards (committees) of several states to entertain making a "critical thinking" or "Introductory logic" course part of the required core.

I have found Susan Wolcott's teaching materials, which are informed by research by K.S. Kitchener and P. M. King, to be the most helpful in addressing student accusations of bias.  I had long been puzzled by why my colleagues in philosophy are so often accused of bias when, in my own observation of their teaching, they take care to keep their own views of a philosophical topic hidden from students.  Indeed, they spend a great deal of time playing devil's advocate and championing the philosophical position that is getting the least airtime in class discussion, readily switching sides if another perspective begins to be neglected.  Wolcott's developmental analysis, which explains how students arrive at college as "confused fact finders" and often get stuck in learning critical thinking skills at the "biased jumper" stage, helps me to understand how students attribute bias to professors when the students lack skills to maneuver around arguments.  The most helpful part of Wolcott's analysis is her suggestion that, if one gives students an assignment that is more than one level above their current abilities in critical thinking, they will completely ignore the assignment task.  This failing is particularly visible when students are asked to compare strengths/weaknesses in two arguments but instead write essays in which they juxtrapose two arguments and ignore the task of forging comparisons.  In Wolcott's workbooks (available by request on her website), she describes assignments that are specifically designed to help students build a scaffolding for critical thinking so that, over four years, they can actually leave the "biased jumper" stage and move on to more advanced levels of critical thinking.  One need not be a slavish adherent to the developmental theory behind Wolcott's work to find her practical suggestions extremely helpful in the classroom.   Her chart on stages of critical thinking is the first link below; her website is the second link.   http://www.wolcottlynch.com/Do... http://www.wolcottlynch.com/Ed...

The classroom and campus are not divorced from the polarized language in the greater society wherein people are entrenched in their own views and arguments become heated, hateful, and accusatory.  The focus of this study on political bias is not helpful under the circumstances.  The greater argument is that students need to be taught how to argue effectively, with facts, logic and reasoning not just in the classroom but beyond.

What happened to the 'Sage on the Stage' as the 'provacatuer-in-chief'?  Some of my best classroom experiences came from faculty that prompted critical thinking and discussion by speaking from all sides of an issue.  They were sufficiently informed to deflate weak arguments from students with probing questions.  They also defended an issue from every side with factual information.  In the best instances, I truly did not know the personal position of a faculty member.  It was more important to them to fully and fairly cover an issue than it was to espouse a personal preference.  That spoke volumes to me about the love of learning, critical examination of strongly held personal beliefs, and assertive but fair-minded discourse.  Do those faculty still exist?

The study suggests that those faculty do exist and in fact are numerous, but that students' ever-diminishing skills in critical thinking and argumentation lead them to misunderstand the questioning, challenging Socratic dialogue and "devil's advocate" work of the professor as simple bias. 

When I was teaching controversial subjects the advice from the Administration was, "Teach the debate."  Its pretty hard to "teach the debate" without actually having some of those debates.  When students "checked out" during those debates I always wondered if they were the ones who were going to report on their teaching evaluations that, "the professor was biased."  Of course when the student intellectually "checks out," i.e., remains quiet, only says what they think I want to hear, etc., they are not doing A work in the class.  This reinforces their view that "the professor is biased."

“In response to this explosion of interest about the Kony 2012 film, there have been hundreds of thousands of comments in support of the arrest of Joseph Kony and the work of Invisible Children.

few pieces written that are putting out false or mis-leading information about these efforts.”

This is called slacktivism - the self-deluding idea that by sharing, liking, or retweeting something you are helping out.

contemporary children have very little experience with the kinds of tasks that they'll have to perform as grown-ups. Children have increasingly little chance to practice even basic skills like cooking and caregiving. Contemporary adolescents and pre-adolescents often don't do much of anything except go to school. Even the paper route and the baby-sitting job have largely disappeared.

first with the industrial revolution and then even more dramatically with the information revolution, children have come to take on adult roles later and later. Five hundred years ago, Shakespeare knew that the emotionally intense combination of teenage sexuality and peer-induced risk could be tragic—witness "Romeo and Juliet." But, on the other hand, if not for fate, 13-year-old Juliet would have become a wife and mother within a year or two.

This control system depends much more on learning. It becomes increasingly effective throughout childhood and continues to develop during adolescence and adulthood, as we gain more experience. You come to make better decisions by making not-so-good decisions and then correcting them. You get to be a good planner by making plans, implementing them and seeing the results again and again. Expertise comes with experience.

Wide-ranging, flexible and broad learning, the kind we encourage in high-school and college, may actually be in tension with the ability to develop finely-honed, controlled, focused expertise in a particular skill, the kind of learning that once routinely took place in human societies. For most of our history, children have started their internships when they were seven, not 27

experience shapes the brain. People often think that if some ability is located in a particular part of the brain, that must mean that it's "hard-wired" and inflexible. But, in fact, the brain is so powerful precisely because it is so sensitive to experience. It's as true to say that our experience of controlling our impulses make the prefrontal cortex develop as it is to say that prefrontal development makes us better at controlling our impulses. Our social and cultural life shapes our biology.
