The Definition: What is Tunneling?
Scarcity is not merely a lack of resources; it is a biological mechanism that alters how the brain processes information. When a resource (money, time, food) is scarce, the brain involuntarily focuses entirely on that immediate lack.
Psychologists call this "Tunneling." Imagine looking at the world through a narrow tube. Inside the tube, your focus is hyper-sharp—you know exactly how to pay the rent due tomorrow. However, anything outside the tube—like the exorbitant interest rate on the payday loan you just signed to pay that rent—is literally invisible to your cognitive processing. You aren't ignoring the risk on purpose; your brain simply filtered it out to ensure immediate survival.
The Mechanic: The Bandwidth Tax
Every human has a finite amount of "Mental Bandwidth" (cognitive capacity) available at any given moment. Financial worry runs a heavy background process in your mind that consumes this bandwidth constantly.
Research suggests that the cognitive load of poverty or severe financial distress can reduce functional IQ by approximately 13 to 14 points. This is comparable to the cognitive impairment of losing an entire night's sleep. Essentially, you are attempting to solve the most complex math problem of your life (rebuilding your finances) with a computer that is running at 60% capacity.
Myth vs. Reality
The Myth
"If I just try harder and have more discipline, I will fix this. My bad decisions are a result of laziness or lack of character."
The Reality
Willpower is a finite biological resource, like glucose. You cannot "will" yourself out of cognitive overload. You need systems to reduce the load, not more effort.
Why This Matters in Recovery
Understanding Scarcity changes the strategy for recovery. If the problem is a bandwidth tax, the solution is not "trying harder"—it is "Cognitive Offloading."
This means automating decisions wherever possible. By setting up automatic transfers or using software to track expenses, you move the workload from your fatigued brain to a machine. This frees up bandwidth, allowing your functional IQ to return to baseline so you can make long-term plans again.
