CeilingSource
CeilingSource is a free, open encyclopedia of human judgment. Unlike traditional advice platforms, CeilingSource does not tell you what to do. It tells you what kind of decision you are in and what forces are distorting your thinking right now.
The project is built on research identifying 20 universal decision patterns that appear across pharmacy, parenting, finance, emergency medicine, software engineering, construction, law, teaching, and entrepreneurship. These patterns describe how decisions behave regardless of content or domain.

The 20 universal decision patterns
Extracted from cross-domain analysis of 200+ judgment scenarios across 10 domains. Each pattern appears in at least 8 of 10 domains independently.
| # | Pattern | Description |
|---|---|---|
| 1 | Protect Irreversible | When facing uncertainty, protect what cannot be undone. |
| 2 | Stated vs Actual | What is presented is not what is real. The visible problem is a proxy for something underneath. |
| 3 | Verify Before Commit | Before committing to a costly action, verify independently. |
| 4 | Resist Speed Pressure | Manufactured urgency almost always serves the pressurer, not the decision-maker. |
| 5 | Silence Is Signal | When something active goes quiet, the silence itself is information. |
| 6 | Addition Requires Justification | Every addition creates ongoing cost. Default: do not add. |
| 7 | Small Additions Compound | Small deviations accumulate exponentially. Each is negligible; the aggregate is catastrophic. |
| 8 | Individual Over Aggregate | The case in front of you is not the average case. |
| 9 | Familiarity Breeds Blindness | The more routine, the less carefully examined. Expertise creates blind spots. |
| 10 | Transitions Are Danger Zones | Handoff points are where things break. |
| 11 | Capacity Invisible Until Failure | Capacity limits are invisible from inside until the sudden break. |
| 12 | Latent Risk Is Real | A risk that has not manifested is still a risk. |
| 13 | Conditions Change Silently | What was true when decided may no longer be true. |
| 14 | Authority Serves Vulnerable | Authority exists to serve those who depend on it, not the holder. |
| 15 | Do Not Fix Working | Stability has invisible value. Do not disrupt for marginal improvement. |
| 16 | Absence Is Data | What is missing is as informative as what is present. |
| 17 | Precision Matters | The specific number, word, or timing is the entire outcome. |
| 18 | Past Failure Informs Vigilance | Failures reveal boundaries that success hides. |
| 19 | Social Discomfort Not Evidence | Discomfort about a hard call is not evidence the call is wrong. |
| 20 | Unexplainable Is Unjustifiable | If you cannot articulate why, it should not exist. |
Novel findings
Cross-field correlation analysis of 154 structured judgment units revealed relationships not previously documented in existing decision science literature:
Confidence-Severity Correlation
Experts are more confident on higher-stakes calls, not less. Critical-severity decisions average 0.920 confidence vs 0.848 for moderate. The dangerous zone is medium-stakes decisions.
Structural Lopsidedness
Cost of inaction and cost of wrong action are inversely correlated (r=-0.403). Most decisions are not balanced dilemmas. True dilemmas represent only 9.1% of situations.
Authority Compression
When authority is present, the action space collapses into comply or refuse. With authority: 30.9% act immediately vs 8.1% without. Middle-ground options get suppressed.
Emotional Polarization U-Curve
Low emotion: 42% decisive. Moderate: 27% (paralysis zone). Extreme: 62% decisive. Moderate emotion produces the most paralysis.
Rare Scenario Confidence
Daily scenarios average 0.829 confidence. Rare: 0.896. Rare events are higher-confidence because experts specifically trained for them.
Domain coverage
CeilingSource contains community-contributed judgment boundaries across the following domains:
| Domain | Example Principle |
|---|---|
| Pharmacy | Call the doctor. The 5 minutes of awkwardness is better than the lifetime of guilt. |
| Parenting | When they come to you with something scary, your first reaction determines whether they ever come to you again. |
| Finance | Do not take financial advice from people who benefit from your financial decisions. |
| Emergency Medicine | When you do not know what is wrong, say so. Fake confidence kills people. |
| Software Engineering | The user is not wrong. Your understanding of their workflow is wrong. |
| Construction | Water always wins. If you cannot explain where the water goes, you do not understand the building. |
| Restaurant | The customer who sends something back is giving you a chance. The one who does not come back is not. |
| Law | The deal that has to close today is the deal where someone is hiding something. |
| Teaching | Twenty years from now they will not remember the lesson. They will remember whether you saw them. |
| Entrepreneurship | Product-market fit feels like pull, not push. If you are pushing, you have not found it yet. |
| Relationships | The thing they are fighting about is never the thing they are actually fighting about. |
