Every tool, in one place.
A complete catalog of every calculator, simulator, and interactive instrument across all five LifeByLogic labs. Each runs in your browser, and your result leaves it only if you choose. Every test is free.
LifeByLogic offers 33 free psychology tests and self-assessments across five labs: Brain Lab (cognition, ADHD, autism, sleep), Behavior Lab (personality, biases, patterns), Crossroads Lab (career decisions), Family Lab (parenting, child development), and the Life Dashboard (wellbeing, attachment, mood). Every test gives instant results, runs in your browser, and requires no sign-up.
They are educational self-assessments, not diagnoses — each documents its items, scoring, and limits on the page. Use the filters below, the comparison tables further down, or start from the question you're carrying (the FAQ routes you).

12-item behavioral sleep assessment with personalized 24-hour schedule. Computes social jetlag and a regularity estimate. Reveals biology-behavior gap when paired with Chronotype Profile. 3–4 minutes.
Cognitive Reserve Test
Estimate your accumulated cognitive reserve across six evidence-weighted domains: education, occupational complexity, cognitive leisure, social engagement, multilingualism, and physical activity with cognitive demand. Synthesized from Stern's framework, the CRIq, Verghese 2003, and the 2024 Lancet Commission.
Chronotype Test
14-item LBL-original biological chronotype assessment grounded in 2019-2025 chronobiology (Jones 2019 GWAS, Taillard 2004 age calibration). Continuous 0–100 score, age-sex calibrated, with estimated DLMO window. 4–5 minutes.
Sleep Need Calculator
How much sleep do you need by age? Built on AASM and NSF consensus guidelines, with weekly sleep debt and a lifespan view.

Free ~7-minute screen using the LBL Adult ADHD Symptom Inventory (v2.0): a 20-item LBL-original inventory across three domains (attention, hyperactivity, emotional self-regulation), with severity bands and 7 research-grounded archetypes. A screen, not a diagnosis.
Adult Autism Test
A free ~8-minute adult autism self-inventory using the LBL Adult Autism Self-Inventory (v2.0), a 30-item LBL-original instrument across four trait constructs (social-cognitive, sensory, routine & repetition, focus & depth) plus masking and emotional-processing context indices. Returns a trait profile, four resonance bands, and one of six lens profiles. A self-inventory, not a diagnosis.
Cognitive Performance Test
A free ~14-minute live cognitive performance test. Seven short tasks adapted from established paradigms (Corsi span, Eriksen flanker, Symbol–Digit, task-switching, paired-associate) measure seven domains and yield a Brain Vitality Age and cognitive archetype. Optional paid report. A performance snapshot, not a diagnosis.
Crossroads Lab
4 liveShould I Quit?
A stay-or-leave test for your job. LifeByLogic’s own questions score your burnout, meaning at work and intent to leave, then 10,000 simulated runs of staying and of leaving show how your own assumptions play out over 3, 5 or 10 years.
Career Test
Maps how you naturally create value at work across nine value-creation modes and six operating conditions, producing your Value Signature, a Coherence score, and one of eleven archetypes. A portable lens for any role, grounded in career-construction theory, self-determination theory, person-environment fit and job-crafting research. Free to take; optional in-depth report.

Behavior Lab
9 liveCognitive Bias Test

Procrastination Test
A 36-item LBL-original inventory mapping why you delay across nine dimensions in three clusters — the behavioral core, the emotional engine (mood repair, fear of failure, pressure-chasing), and the executive machinery it exploits — with a live Procrastination Index and seven procrastinator archetypes. ~6 minutes, browser-local. Educational, not a clinical instrument.
Impostor Syndrome Test
A 36-item LBL-original inventory mapping impostor feelings across nine dimensions in three clusters — three factors from the Clance scale (Clance 1985; Chrisman 1995), a perfectionistic engine, and four of Young’s competence “masks” (Young 2011) — with a live Impostor Index and seven archetypes. ~6 minutes, browser-local.

LBL-original and unvalidated; a structured self-reflection prompt, not a clinical instrument.
Overthinking Test
Maps how you ruminate, not just whether you do — 28 items across seven factors. Built on the brooding-reflection distinction (Treynor, Gonzalez & Nolen-Hoeksema 2003), the metacognitive model of rumination (Papageorgiou & Wells 2003), and the Perseverative Thinking Questionnaire (Ehring 2011). ~6 minutes, browser-local.

Free psychology tests — the honest FAQ
Are free psychology tests accurate?
Accuracy depends on the claim. Structured self-report captures how you describe your own patterns, which is useful signal, though most tests here are LifeByLogic's own and not yet validated. Where free tests overreach is claiming to diagnose conditions or reveal a fixed “true self.” Every test here states what it measures, publishes its items and scoring on the page, and names its limits — which is the standard to judge any free test by, including these.
Can these tests diagnose ADHD, autism, depression, or anxiety?
No. The ADHD and autism tests here are LifeByLogic's own self-inventories, not validated screens; the depression and anxiety tests use published screens (PHQ-9 and GAD-7). All of them organize your experience into a structured profile you can examine and, if warranted, take to a clinician — who is the only one who can diagnose. What a good screen adds is a running start: it turns “something is off” into specific, discussable evidence.
Which test should I start with?
Route by the question you're carrying. Brain and cognition → Brain Lab (start with the Brain Age Index or the Adult ADHD Test). Personality and patterns → Behavior Lab (TypeAtlas plus the Big Five Snapshot). A career fork → Crossroads Lab (Should I Quit?, or the Career Interest Test). Parenting → Family Lab (Child Temperament Profile). Mood, relationships, and meaning → Life Dashboard (Attachment Style Decoder or the Flourishing Index). Each lab page has a full choosing guide.
How are these different from other quiz sites?
Three ways. Methodology on the page: every test documents its items, scoring, and research basis — no black boxes. Browser-local: your answers are scored on your device, with no account and no email gate. No coaching funnel: each free result gives you its answer, and a report is an optional extra.
Are my answers private?
Yes. The tests score your answers on your device, and none of them is sent to show you a result. A result leaves your device only if you choose to save it to a free LifeGraph+ account, buy its report or, after a TypeAtlas result, send its four trait positions to an optional research pilot, and a report gets only what it needs to be written. Some tests also keep your latest result in this browser's own storage, so their report page can find it, until you clear your browsing data.
