Y12W29WR Opportunity cost, and why economists think differently

Observational
The writing prompt

Apply opportunity-cost thinking to a specific allocation decision you face (time, money, or attention), and report on what the framework surfaces and what it misses.

1Retrieval check

Q1.What is Bastiat’s ‘seen and unseen’ framing?

  • AVisible vs. invisible phenomena
  • BWe notice what a decision produces but miss what it prevents — policy evaluation requires attending to both
  • CA theory of aesthetics
  • DA theory of optical illusions

Q2.What’s the article’s caveat about opportunity-cost thinking?

  • AIt’s always wrong
  • BTaken to extremes, it produces paralysis (‘I should always be doing the most valuable thing’) and misses that satisficing is usually optimal
  • COnly economists should use it
  • DIt’s only useful for business decisions
Show answer key

Q1 → B. We notice what a decision produces but miss what it prevents — policy evaluation requires attending to both.Opportunity cost is the ‘unseen’ made visible.

Q2 → B. Taken to extremes, it produces paralysis (‘I should always be doing the most valuable thing’) and misses that satisficing is usually optimal.The framework is a tool for significant decisions, not a universal rule.

2Prompt deconstruction

Stimulus
Opportunity cost; Bastiat’s seen/unseen; the satisficing caveat.
Scope
A specific personal allocation — time, money, or attention.
Method
Apply the framework; report what it surfaces and what it misses.
Thinking
Does the analysis clarify or paralyse? Is paralysis signalling something real?
Output
A specific decision defended with reference to both the analysis and its limits.

3Pick nudge

Which allocation decision will opportunity-cost thinking make clearer?

Time
Study hours, sleep, training, time with family.
Money
A specific discretionary amount.
Attention
Where your attention goes in a typical week.

6Exemplar paragraph (not about this article)

(1) I noticed that applying opportunity-cost analysis to my evening two-hour window changed what I saw before it changed what I did. (2) The specific moment it stood out was listing the alternatives explicitly: study for a weak subject, deep-read for English, sleep earlier, train, or spend time with my brother. (3) Before paying attention, I had been assuming my default (scrolling after homework) was a ‘break’ — but a break is defined by what it restores, and the scrolling was not restoring anything I could name. (4) Bastiat’s seen-and-unseen framing captures what I was missing: the ‘seen’ was the completed homework; the ‘unseen’ was the sleep debt, the weak-subject gap, and the missed training that my default quietly produced. (5) The pattern across a week of tracking is that opportunity-cost clarified the trade-offs I had been making without noticing, but produced paralysis on the ‘best’ use of the window — because the best alternative shifted nightly. (6) What this tells me about the framework is that its value is diagnostic, not prescriptive: it showed me that scrolling was not ‘free time’ but a specific choice with specific costs, and the correct response was not to maximise each night but to rotate deliberately among the top three alternatives.

What this paragraph does, move by move

  1. Names a specific time window and the alternatives.
  2. Catches a false self-label (‘break’ vs. un-restoring scroll).
  3. Uses Bastiat’s seen/unseen precisely.
  4. Distinguishes diagnostic from prescriptive value of the tool.
  5. Engages honestly with the paralysis-under-optimisation problem.
  6. Ends with a rotation rule rather than a maximisation rule.
