Was ist dieses Journal?

A decision journal is a structured practice for recording important decisions at the moment you make them — before you know how they turn out. By capturing your reasoning, alternatives considered, emotional state, and expected outcomes, you create an honest record that lets you evaluate your decision-making process over time, separate from results.

This journal is for leaders, entrepreneurs, investors, and anyone who makes consequential decisions and wants to improve their judgment. It is based on the principle that good decisions can have bad outcomes and bad decisions can have good outcomes — the only way to improve is to evaluate the process, not just the result.

Decision science research, popularized by Annie Duke and Daniel Kahneman, shows that "resulting" — judging decisions solely by their outcomes — is one of the biggest obstacles to better judgment. This journal creates a time-stamped record of your reasoning that you can revisit months later, helping you distinguish between genuine skill and luck in your decision-making.

Ausgefülltes Beispiel

So sieht ein typischer Eintrag aus, wenn er ausgefüllt ist:

Tuesday, March 4
Entscheidungssicherheit 7/10
Emotionaler Zustand 6/10
Tragweite 8/10
Umkehrbarkeit 4/10
Die Entscheidung
I am accepting the job offer from Company B and declining Company A, even though Company A offered 15% more salary.
Kontext
I have been job searching for 3 months after being laid off. Company A is a large corporation with a higher salary but rigid structure and long commute. Company B is a growing startup with lower salary but equity, remote flexibility, and a role that aligns more closely with where I want my career to go in 5 years.
Alternativen
1. Accept Company A for the financial security and stability. 2. Accept Company B for the growth potential and lifestyle fit. 3. Negotiate with Company A on remote work (attempted — they declined). 4. Continue searching (risky — savings are limited).
Begründung
The 15% salary gap will be offset by zero commute costs and time savings. Company B equity could be worth significantly more if they hit their growth targets. More importantly, the role at B directly develops skills I need for my long-term career vision. I would rather earn slightly less doing work that excites me than earn more in a role that feels like treading water.
Erwartetes Ergebnis
Short-term: tighter budget for 6-12 months. Medium-term: rapid skill growth and meaningful portfolio work. Long-term: better career trajectory than Company A would provide. I expect to feel occasional doubt about the money in the first few months but increasing confidence as I grow into the role.

Tipps für den Erfolg

Write down your reasoning BEFORE you know the outcome. This pre-commitment prevents hindsight bias, where your brain rewrites history to make past decisions seem obvious
Rate your confidence level (0\u2013100%) for each decision. Tracking calibration over time reveals whether you are overconfident, underconfident, or well-calibrated
Record your emotional state at the time of deciding. Research by Antonio Damasio shows that emotions are integral to decisions, and recognizing their influence improves future choices
Note what alternatives you considered and why you rejected them. The best decisions are not just good choices \u2014 they are choices made after seriously considering the alternatives
Revisit decisions after 30, 90, and 365 days to record outcomes. The gap between predicted and actual outcomes is where your decision-making skills grow the most

Wann und wie oft schreiben

Write an entry for every significant decision: career moves, large purchases, relationship choices, health changes, and strategic pivots. Minor daily decisions do not need logging, but any choice you might second-guess later deserves an entry. At the decision point, spend 10\u201315 minutes writing your reasoning and confidence. Set calendar reminders to revisit at 30, 90, and 365 days. Quarterly, review your decision history to identify recurring biases.
