The Communist Manifesto by Karl Marx

My rating: 5 of 5 stars


How does one rate a classic? If one could only change the world in 30 pages or so! What always strikes me is that, much like Dr John Hewson's Fightback! policy from the early 1990s, most of the pamphlet has been implemented already (sans the revolution, and admittedly Hewson's work was considerably longer at 650 pages!). Nevertheless, of the ten "measures" (p. 20), Australia has, over time, implemented many of the plans through what, in some ways, still displays remnants of social democracy. However, as with Fightback!, and while many like to think it was all nonsense, much of it has been done or is still in the doing. Whether the great Internationale will die with the contemporary return to nationalism is a moot point when one considers the exponential increase in growth and power of "socialism with Chinese characteristics" (not to mention India, which is quite another story). But this probably won't concern me, at least in this life.

The Inner Life by Thomas à Kempis

My rating: 3 of 5 stars

Penguin's Great Ideas series showcases important works in an abbreviated format (not my favourite way to read), and this work by Thomas à Kempis is drawn from the larger work The Imitation of Christ. After reading Benjamin Franklin (see his 13-week virtues program in The Autobiography of Benjamin Franklin), Albert Camus, and James Allen, I can see the connections to this work dating from the early fifteenth century. There are also elements of Stoicism, recalling Marcus Aurelius. For example, on death at p. 20:

If you are not ready to die today, will tomorrow find you better prepared?

And of being in the world, especially when one is distracted by others, on p. 28:

But to be able to live at peace among hard, obstinate, and undisciplined people and those who oppose us, is a great grace, and a most commendable and manly achievement... He who knows the secret of endurance will enjoy the greatest peace. Such a one is a conqueror of self, master of the world, a friend of Christ, and an heir of Heaven.

Here, James Allen's meditations shine through and it is pleasing to read these in the original. Having said that, there are times when the dialogue between Christ and the disciple, I suppose borrowing from Plato, irked me a little. Nevertheless, there is one part where, and I say this without having researched others' views on the matter, but in Chapter 2 of Book 3 (pp. 40-41), entitled How Truth Instructs us in Silence, the disciple raves on and on and never lets God put a word in edge-wise. This reminded me of Franklin's second virtue, silence, and how we tend to talk too much. I wonder if this was a precursor to the style of La Rochefoucauld? It certainly had me yelling at the disciple to just shut up and listen! Finally, Franklin's thirteenth virtue, to be like Jesus or Socrates, might make the reading of the complete book worthwhile. This is the most difficult of the virtues to comprehend. My reading of Kempis suggests that to think ourselves capable of imitating Christ is folly, and as a non-Christian, even emulating Socrates is egotistical, especially if one were to self-assess as anything other than a black mark for each day for not having been able to be so. Again, without looking to others, what I have gained from Kempis is not that we can imitate Christ (or Socrates, for that matter), but that we can only strive for the ideal. In self-assessing against Franklin's thirteenth virtue, I can only ever give myself a perforated black mark, as I could never say I had reached such levels of perfection (some suggest that Socrates belongs to the list of Abrahamic prophets, so he may well be out of reach, too). And yet the struggle over this one problem is exactly what Kempis suggests we do. Herein lies the genius of Franklin. In assessing himself every day for thirteen weeks, I doubt he could ever not give himself a black mark; yet every day he was reminded to strive for the ideal, no matter how imperfect a man may be in (as opposed to "of"), the world.

The Dunning-Kruger Effect, or: The Illusion of Confidence

What know-it-alls don’t know, or the illusion of competence

One day in 1995, a large, heavy middle-aged man robbed two Pittsburgh banks in broad daylight. He didn’t wear a mask or any sort of disguise. And he smiled at surveillance cameras before walking out of each bank. Later that night, police arrested a surprised McArthur Wheeler. When they showed him the surveillance tapes, Wheeler stared in disbelief. ‘But I wore the juice,’ he mumbled. Apparently, Wheeler thought that rubbing lemon juice on his skin would render him invisible to videotape cameras. After all, lemon juice is used as invisible ink so, as long as he didn’t come near a heat source, he should have been completely invisible.

Police concluded that Wheeler was not crazy or on drugs – just incredibly mistaken.

The saga caught the eye of the psychologist David Dunning at Cornell University, who enlisted his graduate student, Justin Kruger, to see what was going on. They reasoned that, while almost everyone holds favourable views of their abilities in various social and intellectual domains, some people mistakenly assess their abilities as being much higher than they actually are. This ‘illusion of confidence’ is now called the ‘Dunning-Kruger effect’, and describes the cognitive bias to inflate self-assessment.

To investigate this phenomenon in the lab, Dunning and Kruger designed some clever experiments. In one study, they asked undergraduate students a series of questions about grammar, logic and jokes, and then asked each student to estimate his or her score overall, as well as their relative rank compared to the other students. Interestingly, students who scored the lowest in these cognitive tasks always overestimated how well they did – by a lot. Students who scored in the bottom quartile estimated that they had performed better than two-thirds of the other students!

This ‘illusion of confidence’ extends beyond the classroom and permeates everyday life. In a follow-up study, Dunning and Kruger left the lab and went to a gun range, where they quizzed gun hobbyists about gun safety. Similar to their previous findings, those who answered the fewest questions correctly wildly overestimated their knowledge about firearms. Outside of factual knowledge, though, the Dunning-Kruger effect can also be observed in people’s self-assessment of a myriad of other personal abilities. If you watch any talent show on television today, you will see the shock on the faces of contestants who don’t make it past auditions and are rejected by the judges. While it is almost comical to us, these people are genuinely unaware of how much they have been misled by their illusory superiority.

Sure, it’s typical for people to overestimate their abilities. One study found that 80 per cent of drivers rate themselves as above average – a statistical impossibility. And similar trends have been found when people rate their relative popularity and cognitive abilities. The problem is that when people are incompetent, not only do they reach wrong conclusions and make unfortunate choices but, also, they are robbed of the ability to realise their mistakes. In a semester-long study of college students, good students could better predict their performance on future exams given feedback about their scores and relative percentile. However, the poorest performers showed no recognition, despite clear and repeated feedback that they were doing badly. Instead of being confused, perplexed or thoughtful about their erroneous ways, incompetent people insist that their ways are correct. As Charles Darwin wrote in The Descent of Man (1871): ‘Ignorance more frequently begets confidence than does knowledge.’

Interestingly, really smart people also fail to accurately self-assess their abilities. As much as D- and F-grade students overestimate their abilities, A-grade students underestimate theirs. In their classic study, Dunning and Kruger found that high-performing students, whose cognitive scores were in the top quartile, underestimated their relative competence. These students presumed that if these cognitive tasks were easy for them, then they must be just as easy or even easier for everyone else. This so-called ‘imposter syndrome’ can be likened to the inverse of the Dunning-Kruger effect, whereby high achievers fail to recognise their talents and think that others are equally competent. The difference is that competent people can and do adjust their self-assessment given appropriate feedback, while incompetent individuals cannot.

And therein lies the key to not ending up like the witless bank robber. Sometimes we try things that lead to favourable outcomes, but other times – like the lemon juice idea – our approaches are imperfect, irrational, inept or just plain stupid. The trick is to not be fooled by illusions of superiority and to learn to accurately reevaluate our competence. After all, as Confucius reportedly said, real knowledge is knowing the extent of one’s ignorance.
