Wicklander-Zulawski (WZ) technique

Definition

A non-confrontational interview method widely used in private-sector fraud investigations. The interviewer builds rapport, presents the evidence indirectly, rationalises the subject's behaviour, and invites a disclosure rather than demanding a confession. Reduces the risk of false admissions and legal challenge compared to direct confrontation.
