Weighted Pros & Cons

When to use it

Reach for it on any yes-or-no decision where a plain list feels wrong — where you have one huge reason and four small ones, or vice versa, and a tally of five-to-one is lying to you about which side is stronger.

When it's the wrong tool

Skip it when you can't honestly rank your reasons yet — if you don't know what matters most, assigning weights just dresses up a guess as a score. It also fails on decisions where the reasons aren't comparable on one scale, like choosing between two job offers where the trade-off is salary against a relationship, not two numbers.

An example

A tenant is deciding whether to break a lease six months early. The pros are short and heavy: a job offer in another city, a rent that's become unaffordable. The cons are longer but lighter: losing a familiar apartment, the hassle of packing, an early-termination fee, leaving a neighborhood he likes. Counted plainly, four cons beat two pros. Weighted, the job offer and the rent alone outscore the whole list of cons.

How it works

1. List every reason for the decision, then every reason against it.
2. Assign each reason a weight for how much it actually matters to you.
3. Let the tool total both sides and show you the weighted score.
4. Check the result against your gut — if they disagree, ask which one is wrong.
