Simulate the decision before you live it.
Monte Carlo simulators and multi-variable calculators for life's biggest forks — career, education, relocation, and life transitions. Grounded in prospect theory, regret minimization, and behavioral economics.
Not advice. Arithmetic.
Every tool turns a gut-check into a multi-variable simulation. The output isn't a verdict — it's a structured view of what you're already weighing.
Should I quit my job?
A 9-factor decision simulator combining compensation, burnout (Maslach-based), career trajectory, financial runway, and opportunity cost. Delivers a composite Quit Score and a bandwidth recommendation — Stay and Invest, Plan Exit, or Leave Now.
Career Switch ROI
Model the 5-year financial and career trajectory of switching fields — salary curves, reskilling costs, seniority reset, and opportunity cost versus staying.
Grad School Worth It?
NPV analysis of a graduate degree — tuition, foregone earnings, expected salary lift, field-specific ROI. For MBA, MS, PhD, MD, JD, and MPH paths.
Big Move Simulator
Should you relocate? Models cost of living, tax differential, career access, social capital loss, and hedonic adaptation against your current location.
Side Hustle Viability
Calculate realistic break-even timelines for a side project — capital requirements, hour economics, customer acquisition reality, and the probability of crossing to full-time.
How Crossroads tools are built.
Three principles shape every simulator in this laboratory. They are what separates decision arithmetic from opinion dressed in numbers.
Ranges, not verdicts
Real decisions involve uncertainty. Every tool runs thousands of Monte Carlo simulations to produce a range of likely outcomes — not a false-precision single answer. You see the shape of the decision, not a false verdict.
Behaviorally aware
Our models account for known cognitive distortions — loss aversion, sunk-cost thinking, hedonic adaptation, planning fallacy — rather than assuming you're a rational agent. The tools are more honest because they acknowledge you aren't.
Published foundations
Every weight, every distribution, every assumption traces back to peer-reviewed research — Kahneman & Tversky, Maslach, Bureau of Labor Statistics cohort data, Harvard Business Review longitudinal studies. Cited inline, not hidden.
Other laboratories in the publication.
LifeByLogic is organized into four labs, each focused on a different dimension of the examined life.
Brain Lab
Neuroscience-backed tools for cognitive health. Brain Age Index, Sleep-Cognition Optimizer, and more.
Behavior Lab
Behavioral economics and cognitive psychology tools to detect biases, build better habits, and resist manipulation.
Life Dashboard
Your personal analytics engine. Track sleep, mood, spending, and productivity — and surface the patterns hiding in plain sight.
