BharatNotes The sunk cost fallacy is neurologically real — a normally functioning brain resists abandoning goals it has invested heavily in. This means the quit/continue decision cannot be made reliably immediately after a result disappointment. The rational approach: set explicit decision criteria before each attempt, not after, and evaluate prospective value (what is the expected outcome of one more attempt?) separately from past investment.
Why This Decision Is Structurally Hard
A 2024 Oxford neuroimaging study found that individuals with damage to key sunk-cost-processing brain regions were more flexible about switching to better goals — not less. This means sunk-cost bias is a feature of a normally functioning brain, not a reasoning failure. Simply knowing about it does not eliminate it.
The aspirant who has spent 4 years on UPSC is not being irrational when they find it hard to quit. Their neurology is working as designed.
Decision fatigue compounds the problem. The quit/continue decision made immediately after a result disappointment is among the worst-quality decisions a person can make — made at peak emotional load, peak cognitive depletion, and peak sunk-cost salience.
A Framework That Works
Step 1 — Separate past investment from prospective value. “I’ve given 4 years” is about the past. “What is the expected value of one more attempt given my current performance trajectory?” is about the future. Conflating them produces poor choices.
Step 2 — Apply the 37% rule (Optimal Stopping). From applied probability: after evaluating 37% of your available attempts, continue only if performance metrics are improving — not from sunk-cost momentum. If your remaining window is 3 attempts, the evaluation phase is approximately 1 attempt.
Step 3 — Set decision criteria before the attempt, not after. Pre-commitment decisions made in calm states consistently outperform post-result decisions. Before each attempt, write down: “If my Prelims score does not reach X, I will seriously evaluate alternatives.”
Step 4 — Ask the NIH OITE question. “If I were starting fresh today with the same skills I have now, would I choose this path?” This neutralises prior investment as a variable.
The Three-Question Test
| Question | Signal |
|---|---|
| Is my score trajectory improving across attempts? | Most important signal |
| Do I have at least 1 remaining attempt within the age/attempt limit? | Hard constraint |
| Is my financial and psychological cost sustainable for 1 more full cycle? | Be specific |
If all three are yes — continue. If the first is clearly no across multiple attempts with genuine effort — this is the key signal.
What Quitting Is Not
Leaving UPSC is not failure. The preparation cycle builds skills that transfer directly to State PCS, RBI Grade B, SEBI, policy research, and teaching. Make the decision deliberately. Don’t drift.
