Pros & Cons Decision Maker

Weighted pros-and-cons decision framework

This is the old weighted pros-and-cons method, the one Benjamin Franklin sketched out in his 1772 "moral algebra" letter to Joseph Priestley. You give each argument a weight, usually somewhere from 1 to 5, and the tool computes balance = Σ pros · weight − Σ cons · weight. If the balance lands at +3 or higher, that's a nudge toward going ahead. At −3 or lower, lean against it. Anything in the middle means you haven't gathered enough to decide yet, so give it more thought. Take a job offer: pros of "promotion (5) + raise (4) + learning (3)" come to 12, cons of "relocation (4) + far from family (5)" come to 9, and the balance of +3 tilts toward yes.

Applications and context

It fits career changes and major purchases, but also relationships, the capture-and-decide reviews from GTD (David Allen), and the trade-offs leaders weigh every day. A few other frameworks pair well with it. The Eisenhower matrix sorts tasks by urgent × important in a 2×2 grid. Suzy Welch's 10-10-10 asks how you'll feel about the choice in 10 minutes, 10 months, and 10 years. John Boyd's OODA loop (Observe, Orient, Decide, Act) suits fast-moving calls, and Dave Snowden's Cynefin helps you pick a method that matches whether the situation is simple, complicated, complex, or chaotic.

FAQ

Doesn't weighting introduce subjectivity? It does, and that's exactly what you want. Having to put a number on each argument drags out preferences your gut keeps hidden. Buridan's donkey starves because it never manages to say which option matters more.

What if pros and cons are tied? When the balance sits near zero, the problem is usually that you're missing information, not that you can't make up your mind. So ask yourself what fresh data would move a weight by 2 or more.

When is this method wrong? Whenever a choice can't be undone, what Jeff Bezos calls a "type 1" decision. Those deserve more friction than a quick score: run a pre-mortem, get a second opinion, sleep on it.
