Background:

The Behaviour Analysis Interview (BAI) is a technique designed to differentiate liars and truth-tellers.
Inbau et al. (2001) predicted liars would be less helpful and more nervous than truth-tellers.
Deception literature suggests liars may be more aware of their responses, potentially appearing more helpful and relaxed.

Purpose of the Study:

To empirically test the predictions of the Behaviour Analysis Interview (BAI).
To compare the verbal and non-verbal responses of liars and truth-tellers during a BAI.
To assess whether deception literature or BAI predictions align with observed behaviors.

Main Methods:

Conducted a Behaviour Analysis Interview (BAI) with 40 undergraduate participants.

Related Experiment Videos

Participants were instructed to either lie or tell the truth about an event.

Interviews were coded according to Inbau et al.'s (2001) guidelines.

Main Results:

Truth-tellers were more naive and evasive when explaining the interview's purpose compared to liars.
Truth-tellers were less likely to identify individuals they were certain did not commit the crime.
Truth-tellers displayed more nervous behaviors than liars.

Conclusions:

The study's findings contradict the predictions of the Behaviour Analysis Interview (BAI).
Results align with deception literature, suggesting truth-tellers may exhibit more nervousness and evasiveness.
The BAI may not effectively distinguish between liars and truth-tellers based on these behavioral indicators.
