The science
Rewire how you decide, in the moment it counts.
Decision Space trains you inside real decisions. It interrupts the default reaction, makes you read what the moment calls for, and turns that sequence into a habit, so you adapt faster under pressure. Here is the research behind each piece.
The problem
Training is separated from practice.
Leaders learn in workshops and lead later, alone, under pressure. The cue that a moment calls for something different is easy to miss, the default response is fast, and the feedback comes late, if at all. Experience piles up without calibrated judgment.
The evidence
The ingredients, and where they live in the method.
| Finding | Research | In Decision Space |
|---|---|---|
| Versatility predicts effectiveness r = .72, against .17 for personality | Sherman & Kaiser, 2,410 executives and managers | Six styles, and naming the one each moment calls for |
| Debriefs improve performance About 25% on average | Tannenbaum & Cerasoli, Human Factors, 2013 (46 samples) | A structured review of every committed decision |
| Reflection improves learning 22.8% higher test scores | Di Stefano, Gino, Pisano & Staats, field study | Stating goals and assumptions, then explaining what happened |
| Feedback on predictions sharpens judgment 6–11% more accurate | Chang, Chen, Mellers & Tetlock, 2016 | A written prediction, checked against the outcome |
| Specific plans get carried out d = 0.65 across 94 studies | Gollwitzer & Sheeran, 2006 | A committed plan with concrete steps and opening words |
| Intentions are less clear than we think | Gilovich, Savitsky & Medvec, 1998 | Each option read from the other side before you act |
| Situational judgment predicts performance ρ = .34, 10,640 people | McDaniel et al., 2001 | The assessment, and the read-the-moment step |
Habit, not a course
Designed to become something you do without the app.
The cue is the weight of a decision that matters. The routine is the same short sequence every time: pause, read, commit, check. The reward is visible progress. Habits take time to form, a median of 66 days in one field study, so the method is built around months of repetition, and a missed week is a pause, not a failure.
