Coach voor Schaarste-denken

The bandwidth tax is already billing you

Your snap wasn’t a character flaw—it’s the classic sign that scarcity of sleep has captured your cognitive bandwidth. Three double shifts means your judgment, impulse control, and error detection are all running on fumes. The New Jersey mall experiment showed that triggering scarcity drops IQ by 13–14 points—equivalent to an all-nighter. You’re past that threshold.

The tunneling trap

Right now, your mind is in a tunnel: “keep the ER running, don’t stop.” That focus feels productive, but it’s blinding you to the long-term costs—medical errors, damaged team trust, and your own health. The short-term efficiency of pushing through is real, but it’s a bad trade.

The decision rule

Ask yourself one question: Would I accept this cognitive state from a colleague covering my patient? If no, you have your answer. Rest is not optional—it’s protocol. A nurse who can’t dose a medication correctly is a liability, not a hero. Force the rest, even if it’s six hours. Your next shift will be safer for everyone.

Your Tunnel Is Real—But So Is Its Cost

Six weeks of runway is a scarcity trigger, and your brain is doing exactly what Mullainathan and Shafir predict: tunneling toward survival. That focus is real—it can feel like clarity—but it taxes the bandwidth you need to weigh long-term consequences. Turning down a stability-building partnership while in a scarcity tunnel is a textbook outcome.

Separate the Two Questions

1. Is the partnership genuinely dilutive to growth? If yes, survival logic may still favor it—runway is the constraint.
2. **Are you rejecting it because it slows growth, or because you can't see past the next six weeks?** Test this: Would you take it if you had twelve months of runway? If the answer flips, scarcity is driving the decision.

A Concrete Reset

Run the numbers with your co-founder before deciding. Calculate the partnership's cash-flow impact on a 12-month horizon, not just the next quarter. If it buys you runway or lowers burn, it is a survival move—just a longer-term one. If it only adds revenue later while draining cash now, your instinct may be correct.

The danger isn't your focus; it's that scarcity makes you treat "slow growth" as fatal when it might be the price of staying alive.

Your Tunnel Is Real, But So Is the Tax

What you're describing is textbook tunneling: the struggling students have captured your attention, and everything outside that tunnel—the thriving kids, your own energy, the quality of your afternoon lessons—has become invisible. That focus feels virtuous, but it's costing you more than it gives.

The Bandwidth Tax Is Eating Your Afternoons

Skipping lunch is a classic scarcity response. Your body treats "not enough time" like "not enough food," and the resulting cognitive depletion drops your IQ-equivalent performance by 9–14 points. That's why your afternoon lessons are worse. You're not lazy; you're bandwidth-taxed.

Reframe the Trade-Off

Ask yourself: Which students lose more when my afternoon teaching quality drops? The struggling kids you're trying to help are exactly the ones who need your sharpest cognition. By sacrificing lunch, you're harming the very group you're prioritizing.

Actionable Fix

• Protect one 15-minute "bandwidth buffer" after lunch—no prep, just recovery.
• Schedule struggling-student prep in 25-minute blocks, not open-ended marathons.
• Track thriving students weekly with one simple metric, so they re-enter your tunnel.

Your focus isn't wrong—it's just unmanaged. Scarcity makes you tunnel; you must build the guardrails.
