Why it is 'better' to be reliable but dumb than smart but slapdash: are intelligence (IQ) and Conscientiousness best regarded as gifts or virtues.

The psychological attributes of intelligence and personality are usually seen as being quite distinct in nature: higher intelligence being regarded a 'gift' (bestowed mostly by heredity); while personality or 'character' is morally evaluated by others, on the assumption that it is mostly a consequence of choice? So a teacher is more likely to praise a child for their highly Conscientious personality (high 'C')--an ability to take the long view, work hard with self-discipline and persevere in the face of difficulty--than for possessing high IQ. Even in science, where high intelligence is greatly valued, it is seen as being more virtuous to be a reliable and steady worker. Yet it is probable that both IQ and personality traits (such as high-C) are about-equally inherited 'gifts' (heritability of both likely to be in excess of 0.5). Rankings of both IQ and C are generally stable throughout life (although absolute levels of both will typically increase throughout the lifespan, with IQ peaking in late-teens and C probably peaking in middle age). Furthermore, high IQ is not just an ability to be used only as required; higher IQ also carries various behavioural predispositions--as reflected in the positive correlation with the personality trait of Openness to Experience; and characteristically 'left-wing' or 'enlightened' socio-political values among high IQ individuals. However, IQ is 'effortless' while high-C emerges mainly in tough situations where exceptional effort is required. So we probably tend to regard personality in moral terms because this fits with a social system that provides incentives for virtuous behaviour (including Conscientiousness). In conclusion, high IQ should probably more often be regarded in morally evaluative terms because it is associated with behavioural predispositions; while C should probably be interpreted with more emphasis on its being a gift or natural ability. In particular, people with high levels of C are very lucky in modern societies, since they are usually well-rewarded for this aptitude. This includes science, where it seems that C has been selected-for more rigorously than IQ. Indeed, those 'gifted' with high Conscientiousness are in some ways even luckier than the very intelligent--because there are more jobs for reliable and hard-working people (even if they are relatively 'dumb') than for smart people with undependable personalities.
