How It Works

Five layers. One coherent picture of how you actually operate.

Most personality products ask you what you think of yourself. Personal Truth Lab investigates the same question from five independent angles — then only accepts a finding when the evidence converges.

L1
Self-perception

What you believe about yourself. Useful, but incomplete on its own.

L2
Structured measurement

Continuous behavioural tendencies scored deterministically from a full assessment.

L3
Observed behaviour

What you actually do — captured through short real-life check-ins over seven days.

L4
External perception

Confidential, aggregated feedback from people who know you in different contexts.

L5
Tested personal strategies

Short experiments comparing approaches to find what genuinely works for you.

Timeline

The 30-day investigation.

Stage 01
Deep Assessment
Roughly 180 structured items across seven domains, mixed with realistic scenarios and forced-choice values conflicts. Designed to expose tendencies rather than reward self-presentation.
Stage 02
Evidence Interview
A private, structured interview investigates contradictions in your responses. It asks for concrete examples — not opinions.
Stage 03
Reality Audit
Seven days of 45-second check-ins about the day's most important task and what shaped whether it happened.
Stage 04
Observer Verification
Three trusted people answer short, behaviour-based questions. Responses are aggregated so no one is quoted individually.
Stage 05
Personal Experiments
Two structured experiments compare specific strategies — for example, daily reporting versus twice-weekly deliverables — for the same underlying goal.
Stage 06
Verified Operating Manual
Findings supported by multiple sources of evidence are consolidated into decision rules, a pressure profile and a 90-day plan.
Example Progression

How a hypothesis becomes a verified rule.

A single finding, tracked as evidence accumulates across the programme.

01Initial hypothesis
Initial confidence · Assessment only

Your responses suggest research may function as a way to postpone emotionally costly commitments.

6Assessment
02Real-life evidence added
Emerging confidence · + 4 check-ins

Delayed decisions during four of seven days when a difficult conversation was on your list.

6Assessment4Real Life
03Observer evidence added
Medium confidence · + 3 observers

Two observers independently describe you as 'slower to commit when the choice affects you personally.'

04Experiment completed
High confidence · + 14-day test

A decision-deadline experiment reduced reopening of settled issues by roughly two-thirds.

High confidence · Verified

Define decision criteria before research; stop information gathering at the agreed deadline unless genuinely new evidence appears.

Note. Findings begin as hypotheses. They become stronger only when supported by multiple, independent sources of evidence. A finding you disagree with is not overwritten — your feedback becomes another source of evidence.
