Dopamine and Motivation

It's a simplification, but approximately on a neurological level, the messenger molecule dopamine is motivation. We respond to incentives (hence the field of economics). Thus if we want to change habits or build new ones, we need to design incentives properly.

The same core group of neurons in our brain that enable learning, also encodes motivation. Changes in the level of the neurotransmitter dopamine affects our learning ability. We are reward-seeking creatures, and dopamine is the messenger of reward.

When this system goes haywire, it can lead to addictive loops of behavior. Our goal, of course, is to hack the system to our advantage, to learn new things. We need positive feedback loops. For enabling new habits without resorting to sticks/carrots, we need to (a) have regular reminders, (b) make new habits short and easy, and (c) journal our progress diligently. The last step will help our motivation, as we can do hard work as long as we know that we are on the right track.

“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.” — James Clear

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...
