Decision OS / Biases
Bias awareness is useful when it changes the process, not when it becomes a label for other people.
Use practical checks for availability, anchoring, confirmation pressure, loss aversion, and overconfidence.
Case notes
Biases makes the decision process visible before the outcome arrives.
The goal is not to become bias-free. Humans use shortcuts because attention and information are limited. The problem is when shortcuts quietly decide for us while we call the result rational.
Decision OS uses bias checks as process hygiene. Do not diagnose other people. Change the process: get an outside view, find base rates, write a second option, search contrary evidence, and create time distance.
01
Check the outside view.
Ask what usually happens in similar situations.
02
Write contrary evidence first.
Confirmation pressure weakens when disconfirming facts have a place.
03
Delay when emotionally flooded.
A short pause can reduce urgency masquerading as truth.
Common problems and experiments
Make the next process move small enough to test this week.
The vivid example dominates.
Experiment
Ask for base rates or three less dramatic examples.
What to watch
Availability loses power when context returns.
The first number anchors me.
Experiment
Generate an independent estimate before looking again.
What to watch
Anchors weaken when there is a competing reference point.
I only look for support.
Experiment
Write the strongest reason your preferred option may fail.
What to watch
Process improves when the favorite option gets challenged.
Prompt to try
Keep one decision sentence visible.
What would I believe if my favorite option were not allowed to defend itself for five minutes?
7-day protocol
The bias check week
- 01 Name the preferred option.
- 02 Write the first anchor influencing you.
- 03 Find one outside-view reference point.
- 04 Write contrary evidence.
- 05 Ask what loss you may be overweighting.
- 06 Take one time-distance break if emotion is high.
- 07 Update the decision card.
Decision checklist
Mark the process, not the outcome.

Heuristics and biases
Tversky and Kahneman described systematic shortcuts in judgment under uncertainty.

Bias checks are educational process tools, not diagnosis or proof of another person's intent.
