Vianega Decision Tools Lab
Tools for clearer decisions and safer experiments.
Three connected tools: diagnose where your thinking bends, turn the cleaned-up thought into a falsifiable bet, then turn the bet into a workflow with feedback loops.

PDT Decision Lab
Make decisions that are testable, confidence-aware, and survivable under uncertainty.
Turn a vague idea into a falsifiable, guarded experiment.Your entries stay in this browser session. This is a thinking tool, not professional advice.
Step 1 of 6
Decision Card
Decision / choice
One concrete sentence - not a topic. "Hire a designer for the landing page" beats "design questions".
Domain
Which area of life this lives in. PDT works the same way across them, but it helps you stay aware of context.
Time window
How long before you commit to a verdict on this. Short windows protect you from drift; long windows let real signal accumulate.
Why now / trigger
Why does this surface today? A trigger that's external is usually a better signal than "I felt like it".
Reversibility
If this turns out wrong, how hard is the rollback? Reversibility is the single biggest input to the risk verdict.
Cost of error
How much does failure cost - money, time, reputation, health, relationships? "Existential" means "would change the course of my life".
Decision risk levelSafe experiment
If the decision matters, make it testable before making it large.

How they connect
Kahneman → PDT → Workflow
Kahneman
Diagnose where the mind is taking a shortcut. Slow the answer down.
PDT
Turn the cleaned thought into a falsifiable, downside-protected bet.
Workflow
Turn the repeated bet into a system with inputs, gates, and feedback loops.
