Diagnose Decision Default Using Behavioral Signals, Not Self-Report
Everyone has a default pattern: over-budgeting (analysis paralysis) or under-budgeting (premature closure). Your default will override complexity assessments unless you apply counter-weights.
Critical: Self-report is contaminated by the bias it’s trying to diagnose. An over-budgeter will say “I wish I had more time” because they ALWAYS wish for more time. Use observable behavior only.
The Two Default Types
| Default | Pattern | Underlying Driver |
|---|---|---|
| Over-budgeter | Every decision feels like it needs more analysis | Perfectionism, fear of regret, high conscientiousness |
| Under-budgeter | Every decision feels urgent, need to move | Time scarcity, anxiety, action bias |
Why Self-Report Fails
| Question | Over-Budgeter Answer | Under-Budgeter Answer | Problem |
|---|---|---|---|
| ”Do you wish you had more time?" | "Yes, always" | "No, I had enough” | Both answers are the bias talking |
| ”Do you wish you decided faster?" | "No, I needed the time" | "Yes, I overthought it” | Rationalizing existing pattern |
The wish is filtered through the bias. It can’t diagnose the bias.
Behavioral Diagnostic Scorecard
Use observable behavior, not feelings:
| Behavioral Signal | Over-Budgeter (1 pt) | Under-Budgeter (1 pt) |
|---|---|---|
| Decision trigger | External force (“had to decide”) | Internal readiness (“felt ready”) |
| Open decision loops | 5+ unresolved right now | 0-2 unresolved right now |
| Opportunity decay | Options expired while deciding | Decided before anything expired |
| Research termination | External stop (forced, exhaustion) | Internal stop (“enough info”) |
| Question trajectory | More questions at end than start | Fewer questions at end |
| Post-decision behavior | Continued researching or second-guessing | Stopped and moved on |
Scoring: Tally each column. Higher total = default type.
Diagnostic Questions (Behavioral, Not Self-Report)
For self-diagnosis:
- “Think of a recent decision with no deadline. What finally made you decide?”
- “How many unresolved decisions are sitting in your head right now?” (Count them)
- “When you were last researching something, what made you stop?”
- “After your last significant decision, did you keep thinking about it or move on?”
For external diagnosis:
Ask: “Tell me about a decision you made recently that didn’t have a hard deadline. Walk me through how it ended — what made you finally decide?”
| Their Answer Pattern | Indicates |
|---|---|
| ”I had to” / “Couldn’t wait anymore” / “Someone needed an answer” | Over-budgeter |
| ”I felt ready” / “I had enough” / “It became clear” | Under-budgeter |
| ”I just picked” / “I was tired of thinking about it” | Frustration closure (either type exhausted) |
For Mixed Results
If scores are within 1 point of each other, the default is context-dependent. Use Situational Signals for Mixed Defaults to predict which default will activate for THIS decision.
Common Trap
Believing you’re the opposite of your actual default. Over-budgeters often think they’re “thorough, not slow.” Under-budgeters think they’re “decisive, not hasty.” The behavioral signals don’t lie — count the open loops, track the decision triggers.
North: Where this comes from
- The Weighing Problem (why defaults distort assessment)
- Bounded Rationality (systematic patterns in decision-making)
East: What opposes this?
- Self-Report Diagnostics (asking what people wish/feel)
- Personality-Based Typing (fixed trait vs. observable behavior)
South: Where this leads
- Counter-Weight Rules by Default Type (what to do once you know your default)
- Situational Signals for Mixed Defaults (predicting context-specific defaults)
West: What’s similar?
- Behavioral Economics (revealed preference over stated preference)
- Process Auditing (observing what people do, not what they say)
