About

Making complex decisions requires more than a simple list. When high-stakes choices - such as a career pivot, property purchase, or strategic business move - are on the table, the "back of the napkin" approach fails because it treats all arguments as equal. A minor annoyance should never cancel out a critical benefit.

This Weighted Decision Matrix solves that problem by introducing variable importance. By assigning a weight (magnitude) to each factor, we convert subjective feelings into objective data. The system calculates a Net Score using the formula n∑i=1 (w_pro − w_con), providing a mathematical vector that points toward the logical winner.

Use the presets to instantly populate common scenarios, or build your custom board. The integrated Visual Balance Bar provides immediate feedback on which direction your decision is leaning, helping to eliminate cognitive bias and decision fatigue.

Formulas

The core algorithm determines the Decision Delta (Δ) by aggregating the weighted vectors of all inputs.

{

S_pro = n∑i=1 w_iS_con = m∑j=1 w_j

Where w represents the weight (importance) from 1 to 5. The final recommendation is derived from:

Net Score = S_pro − S_conS_pro + S_con × 100%

Frequently Asked Questions

In real-world scenarios, a "short commute" (High Value) often outweighs "free coffee in the office" (Low Value). Standard lists treat these as equal. Weighted scoring allows you to assign a magnitude (1-5) to each point, ensuring the final score reflects the true impact of each factor.

A positive score indicates the "Pros" outweigh the "Cons". The magnitude of the number indicates the strength of the decision. A score near zero suggests the decision is contentious and requires more research or a "tie-breaker" factor.

Yes. The tool automatically saves your progress to your browser's local storage. You can also export the final board as a high-quality Image (SVG/PNG) to share with others or keep for your records.

Cognitive biases like the "Sunk Cost Fallacy" or "Recency Bias" often cloud judgment. By forcing you to write down and numerically weight factors, this tool externalizes the thinking process, making it easier to spot irrational attachments to certain arguments.
