O'Neill's read on honesty comes from the narrative, not the body: truth-tellers stay consistent across days, spontaneously correct themselves ('wait, this happened before that'), and include the messy complications ('nobody's day goes perfect'). Liars smooth these out. The absence of cues to deception — no strange gaps or weird moments requiring you to fill in missing pieces — is what makes an account trend truthful.
Origin
Built from O'Neill's polygraph and interrogation career, and demonstrated in the four-day Garrido interview where consistency across sessions signalled truth.
Core principles
- 01Consistency across separate conversations is a strong truth signal.
- 02Spontaneous self-corrections indicate genuine recall, not a rehearsed story.
- 03Truth-tellers include complications; liars smooth them away.
- 04Look for the absence of deception cues, not a single 'tell'.
How to run it
- 1
Test consistency over time
Revisit the account across separate conversations and check whether it holds.
- 2
Watch for spontaneous corrections
Note when the person self-corrects sequence or detail unprompted — a marker of genuine memory.
- 3
Listen for complications
Truthful accounts include things that went wrong or didn't go to plan; their presence trends the story truthful.
Pro tip When a gap or weird moment forces you to fill in missing pieces, ask more questions there.
Watch out A single deviation is a prompt to ask more, not proof of a lie.
In the wild
Across Tuesday to Friday, Garrido's account stayed consistent, he clarified when asked, and he handled complications (victims who fought back and escaped) matter-of-factly.
→ No cues to deception around the Michaela Garrett timeframe led O'Neill to correctly conclude Garrido wasn't the perpetrator.
Common mistakes
Hunting for a single tell
Fixating on one gesture or gap misreads honesty; the signal is patterns of consistency and complication across the whole account.
Is it for you?
Best for
Interviewers, investigators, and anyone assessing the credibility of an account.
Not ideal for
One-off statements with no chance to test consistency over time.
From the transcript
“when complications are introduced to a story... truth tellers will often do that because it's just like this is just what happened”
