The Psychology of Scarcity: Why Consumers Can't Resist What's Hard to Get

Last week, we discussed opportunity cost – the idea that every choice means giving up something else. It's a fundamental concept that helps us understand the trade-offs we face in life and finance. But there's another factor that can sway our decisions: scarcity. When something seems hard to come by, it suddenly becomes much more appealing. This isn't just about marketing tricks; it's rooted in how our brains work. When we perceive scarcity, we focus more on what we might lose rather than gain, which changes how we weigh those trade-offs. 

Building on this idea, scarcity is just as crucial as opportunity cost and forms the latter’s foundation. If resources were abundant enough to meet all our needs, there would be no need to make choices, as scarcity necessitates trade-offs and decision-making. Because of their importance in our daily lives, humans have developed a belief known as a scarcity mindset. As a result, exhibit behaviors like hoarding or over-conservation of resources can start to manifest, which might seem rational in the short term but can limit opportunities for growth and development. 

A scarcity mindset isn't inherently bad; what matters is how you manage it. When applied contextually, it can enhance productivity and resource efficiency. However, it can also lead to tunnelling, the tendency to focus exclusively on a single or limited objective or view. This can impose a cognitive “bandwidth tax”, such that scarcity of one resource, such as money or time, occupies so much of one’s mind that it takes up cognitive resources normally used for other tasks. For example, an approaching deadline for a project (time scarcity) can monopolise one's attention, but at the expense of other projects that could offer more substantial long-term benefits. 

Furthermore, the scarcity mindset has evolved significantly alongside economic growth and worsening income inequality over the decades, making it difficult for disadvantaged populations to escape their circumstances. Certain demographics, such as first-generation immigrants and low-income individuals, are particularly affected. Poverty can instill a strong belief in resource scarcity, making it difficult to change even when conditions improve. This leads to a "survival mode," focusing on short-term financial solutions rather than future planning. The stress of managing limited resources causes decision fatigue, impairs judgment, and makes people more cautious.

In addition to its implications on a personal level, scarcity influences consumer behavior and marketing strategies. Companies recognise the power of scarcity in driving demand and capitalise on it by advertising "limited editions" or claiming limited production quantities. This creates a sense of urgency, boosting profits. However, many companies continue production beyond initial claims, contradicting the idea of scarcity.


Nonetheless, everyone’s decision making is ultimately affected by their scarcity mindset at varying levels. It influences how we perceive value, manage resources, and respond to economic and social pressures. From personal productivity to consumer behavior, the effects of scarcity are multi-dimensional.
