In the opening, the narrator describes fear, family pressure and prolonged sleepless attention to currency quotes. After an improvement, he takes further exposure and regrets it. The account reveals strain rather than a frictionless trading system.
Separate effort from evidence
A decision can feel justified because it has consumed time, money or pride. Those are sunk commitments, not new evidence. Our exercise is to describe the trade as if it belonged to someone else, then identify what information actually supports it.
Worked example
A researcher spends three weeks on a hypothesis and feels obliged to keep it after contradictory results. The three weeks are effort already spent; they do not make the hypothesis more accurate.
Case connection
Effort already invested cannot answer a fresh safety objection. Use this decision failure as an analogy for sunk commitment.
Challenger: review the decision chain
Source-grounded facts
The Rogers Commission found serious flaws in the launch decision process, including communication failures around safety concerns.
Context
Before Challenger’s January 1986 launch, engineers raised concerns about the solid rocket booster joints and cold conditions. The Rogers Commission later reconstructed how those concerns moved through the organisation.
Outcome
The Commission found the launch decision flawed, citing communication failures and conflict between engineering evidence and management judgment. This was an organisational decision failure, not merely a bad final outcome.
- Thiokol engineers initially recommended against launch under the forecast cold conditions.
- After internal discussion, management changed the recommendation.
- Crucial information about previous O-ring damage and the disagreement did not reach key senior launch officials.
Case analysis
Past effort can make stopping feel like admitting defeat. In a decision review, separate that feeling from the current evidence. Ask what the next decision requires, who can challenge it and what information has actually reached the decision-maker. This is a learning analogy; it does not claim that investing and spacecraft safety have identical stakes.
Try it
Write a neutral one-paragraph account of a decision you felt emotionally committed to. Remove words such as “deserve” and “must.”
