The Pervasiveness of Economics: A Deeper Look at Life's Choices

Written on

Chapter 1: Understanding Economics Beyond the Classroom

Economics is often presented in educational settings as a narrow discipline focused primarily on exchanges and market theories. Students delve into concepts like comparative advantage, asset pricing models, and balance of trade. While these topics are valuable, they represent only a fraction of a much broader reality. Examining economics from a wider lens reveals its profound impact on various aspects of existence across the natural world.

At the core of every organism's survival, from the simplest bacterium to humans, lies the crucial question: how should one allocate their limited energy resources for adaptation? In an ideal universe, one might indulge in numerous luxurious possessions—multiple mansions, private jets, and extravagant vehicles. However, just as we can only occupy one mansion at a time, creatures must prioritize their adaptations based on practicality and energy efficiency. For example, owning multiple luxury vehicles does not enhance one's ability to impress potential mates; similarly, for an elephant, the cost of maintaining extravagant wings far outweighs their benefits.

In reality, all life forms face strict limitations. Even billionaires operate under constraints, albeit less severe than those of the average worker. For non-human organisms, the rules are even more rigid. Every calorie expended must yield a significant benefit; otherwise, extinction becomes a looming threat. This fundamental economic principle governs all life—if a bacterium consumes more energy than it gains from food, its existence is at stake. This principle applies universally, wherever complex molecular structures strive to replicate themselves—what we define as life.

This necessity for specialization is evident throughout nature. Plants have adopted a strategy of reduced energy expenditure by remaining stationary, which works well in stable environments. However, if conditions shift dramatically, their survival hinges on dispersing seeds to find more favorable habitats. In contrast, animals invest more energy in mobility, which allows them to seek food but also exposes them to risks of scarcity. Within species, unique adaptations enable survival in specific niches, but the underlying economic principles remain constant: organisms must expend less energy than the benefits they gain from their adaptations to thrive.

An illustrative example can be found in avian species. Take crows, which excel in intelligence but sacrifice elaborate plumage and melodious songs. Peacocks, on the other hand, devote considerable energy to their vibrant displays, leading to less cognitive capacity and simplistic calls. Meanwhile, raptors prioritize speed and powerful hunting tools over intelligence or song.

It's crucial to understand that evolution is not a directed process; it does not work towards a predetermined goal. Each species adapts to survive based on the genetic traits available to them, often in response to gradual environmental changes. The average lifespan of a species is around a million years, but many emerge and vanish within just tens of thousands of years. While some, like bacteria and nautiluses, are long-lived, they represent exceptions in the spectrum of adaptations. Ultimately, a species can only leverage its inherited genes to a certain extent before it exhausts its options for adapting to ecological changes.

The tale of the Smilodon, or saber-toothed tiger, exemplifies the risks of specialization. Over millennia, it honed its features to prey on a specific deer-like species, perfecting its long, delicate canines for a singular purpose. However, when climate change decimated its primary food source, the Smilodon found itself unable to adapt swiftly enough to survive on a broader diet. Thus, it faced extinction—a reminder that life is contingent and lacks a guiding hand.

Transitioning from physical traits to behavior, the same economic equation of effort versus reward persists. Behaviors evolve because they historically benefited our ancestors, but they may become maladaptive as environments shift. Moths, for example, once adept at navigating by the Moon, now perish en masse, drawn to artificial lights that outshine their natural guide. Similarly, North American deer instinctively freeze when faced with disorienting stimuli, a behavior that once served them well but now leads to fatal encounters with vehicles.

In our rapidly changing world, humans grapple with adapting to an environment we've transformed. This disconnect between our evolutionary instincts and modern realities is starkly visible in politics. Many individuals repeatedly vote against their own interests, a phenomenon that Marx misinterpreted when he envisioned a united labor force leading to a utopian society. The reality is far more complex: while some unionization has occurred, it has not universally translated into improved conditions. Moreover, Marx underestimated human cognitive abilities.

Contrary to assumptions made by both Marx and traditional economic models, historical evidence shows that humans struggle to recognize and act upon their best interests. The obesity epidemic serves as a case in point; despite overwhelming evidence of health risks, many remain trapped in behaviors shaped by ancestral scarcity. The same cognitive limitations are evident in politics, where individuals often default to minimal engagement and awareness.

The efficacy of representative democracy relies on an informed electorate capable of thoughtful deliberation. Unfortunately, widespread ignorance and disengagement lead to voters supporting policies detrimental to their welfare. This trend is particularly noticeable in the USA, where many poorly educated individuals consistently support Republican candidates who advocate for legislation benefiting corporations rather than the common citizen.

The economics of energy conservation dictate that representative democracy is likely to yield increasingly unfavorable results. Society, too, suffers from the implications of evolved behaviors; once individuals form beliefs—regardless of their validity—evidence contradicting those beliefs often reinforces their convictions. The rapid dissemination of misinformation online exacerbates this issue, creating echo chambers of unfounded ideas that can have dire consequences.

A striking study in the USA illustrated how energy-efficient our brains can be. Participants in an experiment were unknowingly influenced by holding either a warm or cold coffee cup. Those who held the cold cup perceived an academic as distant, while those who held the warm cup viewed them as friendly. This highlights our cognitive biases and why our beliefs and memories often fail us. Yet, we continue to operate within social systems based on unrealistic assumptions about human cognition, leading to pervasive distortions in various domains, including politics and justice.

To navigate the complexities of our modern world, we must recognize our limitations and design systems that mitigate predictable harms. Unfortunately, signs of such realizations remain scarce.
