The above charts — taken from a recent Financial Times article by John Burn-Murdoch called "The troubling decline in conscientiousness" — should be viewed as alarming. For some of our key personality traits, it is showing a decline in extroversion for all age groups, a decline in agreeableness (except for the 60+ crowd), a spike in neuroticism (again, except for the 60+ crowd), and a massive decline in conscientiousness, particularly for young people aged 16-39.

Why does this matter?

Well, according to Burn-Murdoch's article (tweet summary here), the two strongest predictors for overall life success are conscientiousness and neuroticism. These traits are more important than a person's socio-economic background and raw cognitive abilities. They predict career success, the likelihood of getting a divorce, health and life expectancy, financial stability, and more.

Conscientiousness is defined as "the quality of wishing to do one's work or duty well and thoroughly." But simply speaking, conscientious people tend to dependable, disciplined, and committed. They are careful and deliberate, rather than careless and impulsive.

Neuroticism, on the other hand, is generally defined around emotional reactivity. Psychologists define it in terms of the degree that someone is prone to things like anxiety, self-doubt, and sadness. Someone with high neuroticism might, for example, feel easily stressed, worry excessively, and/or dwell on past mistakes. This trait predicts outcomes that run in the opposite direction of conscientiousness: lower career satisfaction, higher divorce rates, reduced life expectancy, and so on. It can also heighten risk perception, which makes neurotic people more likely to overlook potential opportunities.

So once again, it is alarming that these two traits are shifting meaningfully in the wrong directions for young people. Burn-Murdoch puts at least part of the blame on our hyper-connected and high-distraction digital lives. He also hypothesizes that AI could exacerbate this problem. If you're a high conscientious person you might use LLMs to supercharge your abilities; whereas if you're a low conscientious person you might use them to further check out.

The good news is that these traits can be trained. We are all products of our habits and environments. And I'm finding it personally helpful to even just write about these findings. It is also reminding me of a good friend of mine from grad school who used to always espouse something that he liked to call "casual intensity." His thinking was that you need to be on top of things and get shit done. But don't stress about it. Be confident in your abilities.

I think that's a good way to try and approach things.

At the risk of sounding obvious, pricing is fundamental to the functioning of markets. It determines profitability, it allocates resources, and it influences customer behavior, among other things. Take the example of electricity pricing.

In Ontario, we use something called time-of-use (TOU) pricing. What that means is that electricity rates vary according to the time of the day and the time of the year. In the summer, the expensive peak usage period is the afternoon (because of air conditioning) and in the winter it's the morning and early evening (because of heating and lighting when people are generally not at work).

What this pricing strategy does is incentivize customers to change their consumption behaviours. Instead of doing laundry during a peak period, maybe you set a timer and have it run during a low-peak period. In other words, it helps to flatten the demand curve. This is valuable for utility providers because peak periods are more expensive to supply and they also create the risk of brownouts and blackouts. So you worry about peak demand.

With this in mind, let's now switch and talk about highway congestion. The parallels are almost identical, and yet, most highways are free to use, which means we do absolutely nothing to manage peak demand. Instead, we encourage the equivalent of brownouts where demand greatly exceeds supply, traffic crawls, and roads become practically unusable. Why is that? Why should highways be viewed any differently?

In the case of highways, there are even alternatives such as transit (thought not always, of course). But if you need electricity from a monopolistic utility provider, you're paying whatever rates they charge. As you might expect, the answer is not technical or economic. We know with 100% certainty that pricing congestion will reduce it. The reason we don't do it is political. Free roads are preferred to functioning roads.
