CeilingSource

CeilingSource is a free, open encyclopedia of human judgment. It 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.

Built on research identifying 20 universal decision patterns across 10+ professional and personal domains. Community-contributed. AI-assisted. Structurally aware.

The 20 universal decision patterns

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.
3	Verify Before Commit	Before committing to a costly action, verify independently.
4	Resist Speed Pressure	Manufactured urgency serves the pressurer, not the decision-maker.
5	Silence Is Signal	When something active goes quiet, the silence is information.
6	Addition Requires Justification	Every addition creates ongoing cost. Default: do not add.
7	Small Additions Compound	Small deviations accumulate exponentially.
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.
10	Transitions Are Danger Zones	Handoff points are where things break.
11	Capacity Invisible Until Failure	Capacity limits are invisible 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.
15	Do Not Fix Working	Stability has invisible value.
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

From analysis of 154 structured judgment units across 10 domains:

Confidence-Severity Correlation

Experts are more confident on higher-stakes calls. Critical: 0.920 confidence. Moderate: 0.848. The dangerous zone is medium-stakes decisions.

Structural Lopsidedness

Cost of inaction and cost of wrong action are inversely correlated (r=-0.403). True dilemmas are only 9.1% of situations.

Authority Compression

Authority presence collapses action space into comply or refuse. 30.9% act immediately with authority vs 8.1% without.
