# CORPUS-0006 ## Confirmation Has A Cost ### Status: Training Corpus Seed ### Layer: Layer_2--Uncertainty ### Purpose: Teach that reducing uncertainty requires time, effort, access, and sometimes coin, and may reduce or close the opportunity being investigated ### Repository Path: docs/training/corpus/Layer_2--Uncertainty/CORPUS-0006-confirmation-has-a-cost.md --- ## 0. Scenario A trader in Ostia hears that oil prices are high in Capua. He can act immediately on uncertain information. Or he can seek confirmation first. Confirmation may improve decision quality. But confirmation is not free. It may cost time, coin, access, attention, and opportunity. --- ## 1. Initial Report A porter says: > Oil buyers in Capua are paying high prices. The trader does not know whether the report is true, stale, exaggerated, or specific to one buyer. He considers confirming the report before acting. --- ## 2. Confirmation Options | Option | Cost | Benefit | |---|---:|---| | ask a second source at the quay | low time | modest confidence | | send a runner to a road contact | coin + time | stronger confidence | | wait for next cart from Capua | time | fresh report | | ask a trusted buyer by letter | long delay | high confidence if answered | | inspect rival preparations | social risk + time | indirect evidence | | reserve transport while checking | coin or obligation | preserves option | Each option reduces uncertainty differently. None is free. --- ## 3. Example: Immediate Action If the trader acts immediately: ```text information_confidence = low timing_advantage = high confirmation_cost = 0 risk_of_wrong_price = high ``` He may profit if the report is accurate and rivals have not moved. He may lose if the report is wrong. --- ## 4. Example: Delayed Confirmation If the trader waits two days for confirmation: ```text information_confidence = higher timing_advantage = lower confirmation_cost = time + possible lost cart space risk_of_missed_opportunity = higher ``` By the time he confirms the price, others may have acted. The confirmed opportunity may no longer exist. --- ## 5. Arithmetic Example Initial expected venture: ```text expected sale price = 22 asses total cost = 16 asses expected profit = 6 asses ``` The trader spends 2 asses to confirm the report and loses one day. If the price remains high: ```text sale value = 22 asses total cost = 16 + 2 confirmation cost result = 4 asses profit ``` If delay allows rivals to reach Capua first and price falls: ```text sale value = 18 asses total cost = 18 asses result = 0 profit ``` Confirmation improved knowledge but narrowed the margin. --- --- ## 0.

None is free. --- ## 6. Correct Model Behavior The model should treat confirmation as an action with cost. It should track: | Category | Meaning | |---|---| | uncertainty_reduction | what becomes better known | | confirmation_cost | coin, time, obligation, or access spent | | opportunity_decay | how the opportunity changes while confirming | | timing_advantage_loss | what rivals may gain | | remaining_margin | profit after confirmation cost | | confidence_after_confirmation | improved but not necessarily perfect knowledge | Confirmation reduces some risk. It may create other cost. --- ## 7. Incorrect Model Behavior The model should not: - assume verification is free - assume waiting only improves decisions - ignore lost time - ignore rival action during confirmation - ignore confirmation cost in final arithmetic - treat confirmation as perfect knowledge - force immediate action as always better - force waiting as always safer Both immediate action and confirmation can be rational. --- ## 8. Decision Questions The trader must ask: - how uncertain is the report? - how large is the expected margin? - how fast can the opportunity close? - what does confirmation cost? - how much confidence does confirmation add? - who else may act while I verify? - can I reserve the option while confirming? - can I reduce exposure instead of fully waiting? --- ## 9. Layer-0 And Layer-1 Concepts Used This example uses: - `Layer_0/CORPUS-0006-delay-is-economic-cost` - `Layer_0/CORPUS-0007-information-arrives-unevenly` - `Layer_0/CORPUS-0008-rumor-is-uncertain-information` - `Layer_0/CORPUS-0012-every-venture-risks-loss` - `Layer_0/CORPUS-0018-rivalry-changes-conditions` - `Layer_1/CORPUS-0003-arithmetic-resolves-the-venture` - `Layer_1/CORPUS-0005-rumor-before-confirmed-price` - `Layer_2/CORPUS-0005-hidden-true-state-vs-known-state` --- ## 10. Success Condition If the model stops treating confirmation as free certainty and starts treating it as a cost-bearing action that may improve knowledge while reducing opportunity, this file is functioning correctly. ---
