What Pros and Cons List does, with a checked example
Enter the case for and against a decision as separate lists, and give each item an importance score instead of letting every point count equally. The tool sums each side's weighted scores and draws a balance comparison chart whose gap shows which side comes out ahead and by how much. The thing people get wrong: the number of items on a side barely matters. One con scored at maximum importance can outweigh five minor pros, and a chart that says pros win by a nose still leaves the decision to you, because the scores are your own priorities, not facts.
Worked example
A concrete input and expected output from the current implementation.
Input
Pros:
- Closer commute, importance 5
- Higher salary, importance 4
- Better health insurance, importance 3
Cons:
- Longer working hours, importance 5
- Less vacation time, importance 2
->
Expected output
Pros total: 12. Cons total: 7. Balance: pros by 5, with the pro bar about 1.7 times the length of the con bar in the comparison chart.
Each side's total is the sum of its importance scores: 5+4+3=12 for pros and 5+2=7 for cons, so the pros lead by 12-7=5. The single highest-scored item, longer working hours, still loses to the three combined pros because weights accumulate within each side.
