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. Nothing is stored. Everything 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).
Brain Lab
8 liveBrain Age Test
Estimate the modifiable portion of your brain-age gap across 6 evidence-based domains (25 items). Built on the 2024 Lancet Commission and UK Biobank research (n=38,967).

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.
Adult ADHD Test
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
3 liveShould I Quit?
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. 10,000 simulated futures for both paths across 3, 5, or 10-year horizons.
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, work design, behavioral economics, and human-capital research. Free to take; optional in-depth report.

Rate 36 kinds of work and reveal your three-letter Holland code across the six RIASEC types — drawn live on the classic hexagon with differentiation and consistency metrics and example careers matched to your primary type. 36 LBL-original items, ~6 minutes, browser-local. Interests, not abilities.
Career Change Test
Structured 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. Decision-quality forcing function based on multi-attribute utility theory and career capital research.
Behavior Lab
7 liveCognitive Bias Test
A ~15-minute assessment of susceptibility to seven well-studied cognitive biases using behavioral tasks — not self-report alone. An LBL-original battery, grounded in the heuristics-and-biases and rational-thinking literature (Stanovich, West, and Toplak; Bruine de Bruin; and the bias blind spot research from Carnegie Mellon).

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

The Inner Economy
A 45-question self-reflection inventory mapping how you spend finite drive, attention, and risk across 13 dimensions in three systems — Appetites, Protections, and Treasury — surfacing 10 named tensions and an overall Coherence reading. 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 Treynor & Nolen-Hoeksema's brooding–reflection distinction (2003), Wells's metacognitive model (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 reliably measures how you describe your own patterns — real, useful signal. 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 screening tools here (ADHD, autism, depression, anxiety) 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 never leave your device, with no account and no email gate. No funnel: results don't end in a coaching pitch or an upsell; the result is the product.
Are my answers private?
Yes — structurally, not just by promise. The tests run entirely in your browser: answers are processed on your device and are not transmitted or stored on a server. Close the tab and they're gone.
