Career and life decision tools.
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.
The Crossroads Lab is four free career and decision tools: Should I Quit?, the Career Pivot Decision Matrix, the Career Interest Test (Holland codes), and the Career Choice Signature. Every tool gives instant results, runs entirely in your browser, and requires no sign-up — your answers never leave your device.
They are decision frameworks, not verdict quizzes: they structure the fork you're standing at — finances, fit, interests, values — so the decision you make is yours, made with the variables on the table. They are educational tools, not financial or career advice.
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?
A Monte Carlo decision tool for the stay-or-leave question. Combines two LBL-original assessments — a Burnout Signal (exhaustion + disengagement) and a Meaningful-Work Signal — with a validated turnover-intention measure. Runs 10,000 simulated futures for both paths across 3, 5, or 10-year horizons — with archetype matching, regret minimization, and research-backed pathway recommendations.
Career interest test
Rate 36 kinds of work and reveal your three-letter Holland code across the six RIASEC types (Holland 1959, 1997), drawn live on the classic hexagon with differentiation and consistency metrics and example careers from the public-domain O*NET classification. 36 LBL-original items, ~6 minutes, browser-local. Interests, not abilities — a compass, not a verdict.
Career pivot decision matrix
A 6-domain weighted comparison of your current role and the pivot you're considering — plus a calibration check on how informed your evaluation actually is. Implementation draws on multi-attribute utility theory (Hammond, Keeney & Raiffa 1999), career capital theory (Arthur, Khapova & Wilderom 2005), and decision-quality research. The 5×5 recommendation grid surfaces the high-score-low-readiness trap that contributes to many failed pivots.
Career choice signature
Maps how you naturally create value at work across nine value-creation modes and six operating conditions, then names your Value Signature, a Coherence score, and one of eleven archetypes. A portable lens for any role rather than a job-matching engine, drawing on career-construction theory (Savickas), work design (Hackman & Oldham), behavioral economics, and human-capital research. Free to take; an optional in-depth report reads your exact signature.

Which decision tool should you use first?
People arrive at career tools carrying one of three questions, and here is the observation that shapes this whole lab: if you have taken a "should I quit" quiz more than twice, the quiz is not what you need. Verdict quizzes measure Monday's mood. What a real fork requires is a framework — the variables named, weighted, and put on the table. That is what each tool below does, and the routing depends on which question is actually yours.
"Should I quit my job?" — the leave/stay question
Start with Should I Quit? — a multi-factor simulation of your actual situation: financial runway, role fit, growth trajectory, and the momentum costs of staying versus going. Answer as the person you were this month, not on your worst day, and treat the output as a structured picture of the fork rather than permission. The classic red flags — health suffering, values conflict, a role you've outgrown with nowhere to go — matter more as a pattern than as any single bad quarter, and a good framework makes the pattern visible.
"Is it the job — or the career?" — the pivot question
These are different diagnoses with very different costs, and confusing them is the most expensive mistake at this fork. A bad employer is fixed by a move; a bad field follows you to the next one. The Career Change Test weighs stay / move / pivot as distinct options against your own criteria — compensation, meaning, transferability, retraining cost — so the cheaper fix gets ruled out before you pay for the expensive one.
"What work actually fits me?" — the direction question
Direction has two inputs, and most people only measure one. The Career Interest Test maps your interests onto the Holland framework — the RIASEC model the U.S. Department of Labor indexes every occupation by; the companion essay, What Is a Holland Code?, explains how to interpret your three-letter code like a professional would. Then the Career Test measures the second input: your decision values — what you actually trade away when money, meaning, freedom, status, and stability compete. Interests say what fits; values say what you'll sacrifice to have it. Direction is where those two answers overlap.
How to use decision tools well
Three rules. First, sequence matters: values before direction, direction before the leave/stay call — deciding whether to jump before knowing where you'd land inverts the logic of the fork. Second, answer from evidence, not aspiration: this month's reality, not the identity you're auditioning. Third, treat every output as a hypothesis to test against your situation — each tool documents its methodology and its limits on the page, and no tool on the internet, including ours, should be the thing that quits your job. You should be — with the variables finally on the table.
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.
Read the methodology.
Each tool publishes its full methodology under its own page — the validated framework, the variables measured, the algorithm, the limitations, and the peer-reviewed references behind every claim.
Lee–Mitchell unfolding model, embeddedness theory (Mitchell et al. 2001), Steel & Ovalle meta-analysis.
Multi-attribute utility theory (Hammond, Keeney & Raiffa 1999), career capital theory (Arthur et al. 2005), pre-mortem decision practice (Klein 2007).

Four decision tools, one logic: structure the fork you’re standing at instead of asking a quiz for a verdict. Grouped by the question that brought you here.
You dread Mondays and keep retaking “should I quit” quizzes — what you need is a structured, multi-factor read of your actual situation, not another verdict.
A new employer might fix it. A new field might be what you actually need. Those are different decisions with different costs — weigh them as such.
You want the direction question answered from your interests — the framework the U.S. Department of Labor indexes every occupation by.
You want your decision values on the table — what you actually optimize for when careers compete: money, meaning, freedom, status, stability.
Three ways to use the Crossroads Lab
Career decisions compound, so sequence matters: know what you value, then what fits, then whether to move. Pick the journey that matches where you’re stuck.
Decide whether to leave — properly
Payoff: a multi-factor read of your leave/stay fork — finances, fit, momentum — instead of a mood measured on a Monday.
- Run Should I Quit? honestly — answer as this month, not your worst day.
- If the answer leans “go,” don’t stop: the next journey tells you where.
Find the direction before you jump
Payoff: your three-letter interest code, your decision values made explicit, and a shortlist of work that fits both.
- Take the Career Interest Test — then read What Is a Holland Code? to interpret it like a professional.
- Take the Career Test — interests say what fits; values say what you’ll trade for it.
The complete crossroads sequence
Payoff: the whole fork structured end-to-end — whether to move, in which direction, and at what accepted cost.
- Values first: Career Test.
- Direction second: Career Interest Test + the Holland essay.
- Decision last: Career Change Test, and if leaving is on the table, Should I Quit?
Frequently asked questions.
What does the Crossroads Lab help with?
The Crossroads Lab houses multi-variable simulators and decision-support tools for the high-stakes forks in life: career switches, relocations, quitting a job or relationship, retirement timing, and other major life transitions where the right answer depends on many interacting factors.
How do I know if I should quit my job?
Look for a pattern, not a moment: health suffering, a values conflict that won't resolve, a role you've outgrown with no growth path, and the same complaints surviving multiple managers or projects. Any single bad quarter can mimic all of these — which is why the Should I Quit? tool structures the decision across finances, fit, and momentum rather than handing you a verdict. If the pattern holds when you answer from this month's evidence, that's a signal worth acting on — with a plan, not an exit speech.
What's the difference between needing a new job and needing a career change?
A bad employer is fixed by a move; a bad field follows you to the next employer. The test: imagine the same role at the best company you can picture — if the dread lifts, it's the job; if it doesn't, it's the career. The Career Pivot Decision Matrix weighs stay / move / pivot as separate options with separate costs, so you rule out the cheaper fix before paying for the expensive one.
What career actually fits me?
Fit has two inputs: interests and values. The Career Interest Test maps your interests to the Holland (RIASEC) framework — the model the U.S. Department of Labor indexes every occupation by — and the Career Choice Signature makes your decision values explicit: what you'll actually trade among money, meaning, freedom, status, and stability. The direction worth pursuing is where the two overlap; either one alone routinely points at work you'd resent.
Can a quiz really tell me whether to quit?
No — and be suspicious of any that claims a “100% honest answer.” A ten-question quiz measures your mood on the day you took it, which is why people retake them. What a structured tool can genuinely do is name the variables — runway, fit, trajectory, values — weigh them consistently, and show you the shape of your own situation. The decision stays yours; the tool's job is to make it an informed one.
Is this financial advice?
No. Crossroads Lab tools are educational decision support, not professional advice. They model patterns based on the inputs you provide and the documented methodology of each tool. They do not prescribe choices, do not constitute personalized advice, and do not replace consultation with a qualified professional who knows your specific situation. See our Disclaimer.
How are decision tools different from advice columns?
Advice columns give you one answer based on a stranger's reading of your situation. Crossroads tools give you a structured way to think through your own situation: you provide the inputs, the tool surfaces the patterns implied by peer-reviewed decision research. The output is a frame for your own reflection, not a verdict.
What research informs the methodology?
Tools draw from stay-vs-go decision research, Monte Carlo financial planning methods, multi-attribute utility theory, and the specific peer-reviewed literature for each domain (career change, retirement timing, relocation). Citations and methodology are published on each tool page.
Who reviews the analytical models?
The analytical modeling and results-analysis logic of every Crossroads Lab tool is independently reviewed by Eskezeia Y. Dessie, PhD — Research Fellow at Indiana University School of Medicine, specializing in computational modeling and predictive analytics. See our About page for reviewer details.
