Unskilled Skills vs "Creative" Skills the studies this RSA video highlights are very useful in being able to differentiate what really is "skilled" job. One interesting thing about unskilled jobs the study highlights is that you can design incentives as to more reward creates more work... the way this doesn't work for highly creative and human intelligence and judgement intensive skills is highly enlightening.I'd best leave the video to explain that unusual nuisance of "creative" or skill-mastery.
RSA Animate - Drive: The surprising truth about what motivates us
Profession (mining)-15+ would be the type of skills that require escalating levels of complexity. Such a "skilled" job would mean, the professional exhibits judgment and knowledge that would be expensive and hard to acquire. Such a profession is more of looking at how a mine is run and working towards anticipating Normal Accident Theory, Normalizing Deviance, Practical Drift , as well as effective means of problem solving specific for his profession technology and subtle nuisances. Suffice to say all unskilled aspects are completely automated.
Note for the people burned by the banks, when it comes to bonuses and designing incentives for the executives and people who work in the financial sector where judgement can be easily compromised.
If our soldiers are not overburdened with money, it is not because they have a distaste for riches; if their lives are not unduly long, it is not because they are disinclined to longevity.- Sun Tzu
[Chang Yu has the best note on this passage: "Wealth and long life are things for which all men have a natural inclination. Hence, if they burn or fling away valuables, and sacrifice their own lives, it is not that they dislike them, but simply that they have no choice." Sun Tzu is slyly insinuating that, as soldiers are but human, it is for the general to see that temptations to shirk fighting and grow rich are not thrown in their way.]
