SimpleDecider runs your choices through expected-value math, Monte Carlo simulation, and weighted scoring — so you stop relying on gut and start seeing the shape of every option.
A single expected value hides the shape of risk. Monte Carlo runs your decision through thousands of randomized futures and shows you the distribution — so you can see not just what's likely, but what could go wrong.
A weighted scoring matrix isn't just a spreadsheet — it's a lens. Slide the criteria you care about, and the whole landscape changes. The radar shows option shapes; the matrix reveals the math.
Every option has a silhouette — a stack of weighted contributions across the criteria you care about. Compare three options side-by-side, hover any block to highlight its peers, and let the engine surface the patterns hiding in the totals.
Growth drives this decision more than any other criterion — accounting for 25% of total weighted contribution across all three options.
At your current weights, Job C · Remote wins by Δ0.15 — its silhouette is taller because it concentrates value in the criteria you weight highest.
The widest spread between options sits on Growth — a Δ of 1.00weighted points. If you're uncertain about how much you value Growth, run sensitivity here first.
500+ probability facts pulled from CDC, NHTSA, NCI, SSA, NWS, BLS, and IRS — wired into every decision template. Hover a node to feel the magnitude.
Define the question and generate at least 3 real alternatives — not "do it" vs "don't".
Pick criteria, slide their weights, rate each option. The matrix does the math.
Assign probabilities and payoffs. Run Monte Carlo to see the full distribution of outcomes.
Record your call before knowing the result. Calibrate your judgment over time.
