Common Pitfalls

Today I want to discuss three themes that impede our long-term well-being.

Linear thinking is a common way of thinking about the world. However, in our world many processes compound over time and the returns are geometric. This induces people to underestimate the impact of long-term loans on liabilities such as a car. The reverse is also true — long-term investing leads to surprising build-up of wealth.

Hedonic adaptation is how we get accustomed to lifestyle upgrades quickly and no longer derive any joy from those upgrades. Luxuries become necessities. The inflation in lifestyle costs don't lead to perception of joy, but reduce long-term well-being. 

Loss aversion concerns our distaste for engaging in moderately risky endeavors, even when the odds are in our favor. Unlike the previous two pitfalls, this aspect does have a silver lining — it strives to protect us against catastrophic ruin. But we can never eliminate risk completely — the next best thing is to choose our battles on our own turf. Remember that the risks that hurt you the most are the ones you are completely unaware of.

Quotes from "The Social Leap"

These are the lines from William von Hippel in his book “The Social Leap” that I found to be incisive and insightful. “The ability to kill at a distance is the single most important invention in the history of warfare, because weaker individuals can attack stronger individuals from a position of superior numbers and relative safety.” “As if division of labor were not enough, Homo erectus then sealed the deal with the single most important innovation in human history: the control of fire.” “Long before the invention of writing (which is only about five thousand years old), human culture had become cumulative by virtue of our oral storytelling traditions .” “When we weigh up the costs and benefits, we see that farming afforded our ancestors some assurances against starvation, but at the cost of various new illnesses, reduced stature and longevity, excruciating halitosis, and often a far longer working day. The end result was that early farmers worked harder to achieve a worse life than

Quotes from "Atomic Habits"

 Here are the quotes from James Clear's "Atomic Habits" that I found insightful: “When it comes to habits, the key takeaway is this: dopamine is released not only when you experience pleasure, but also when you anticipate it.” “Once we fit in, we start looking for ways to stand out.” “When the effort required to act on your desires becomes effectively zero, you can find yourself slipping into whatever impulse arises at the moment.” “… the costs of your good habits are in the present. The costs of your bad habits are in the future.” “… avoiding a 33 percent loss is just as valuable as achieving a 50 percent gain” “When you can’t win by being better, you can win by being different. By combining your skills, you reduce the level of competition, which makes it easier to stand out. ”

The Upside of Disaster

In the previous post , I talked about the tactics rational optimists use to deal with uncertainty: explore and exploit. There are situations where an utter disaster and the resulting uncertainty can change the history for the better. An amazing example is the story of human evolution from chimp-like apes. Here's a brief review of the story told by William von Hippel in “ The Social Leap .” These apes lived in the rainforests of eastern Africa, around 6 million years ago. They ruled the canopy. But then disaster struck. Eastern Africa was tearing away from the rest of the continent, due to plate tectonics. The climate changed. The rainforests disappeared. These apes had to adjust to living in the savannah, at the mercy of great predators. Humans reacted to this disaster by innovating and inventing. Human distinctions — from bipedalism, persistence hunting, to the use of language and tools and our social structure — ultimately are the results of that disaster. They learned to be grea
