Guides explain how lie detector testing works - case studies show what it is actually like to use one. Each study below follows a real situation from first phone call to written result: how the questions were designed, what the test day involved, and what the outcome changed. Names and identifying details are altered throughout to protect confidentiality.
A late-night screenshot, a two-month argument, and an accused partner who volunteered for the test himself. How single-issue questions agreed by both partners - and a pre-commitment about what a pass would mean - ended it in ninety minutes.

Five months of losses, four keyholders, three of them innocent. How one employer used voluntary, identical single-issue tests lawfully - clearing three staff in two days and pointing the paperwork at the right person.

Fourteen thousand pounds missing from their mother's savings and a two-year estrangement conducted through solicitors. How a symmetrical pair of tests - identical scope, results shared simultaneously - gave a family itself back.
Read the case studyDifferent situations, same disciplines. Every case here used tightly-scoped single-issue questions rather than fishing expeditions - the question design guide explains why that is where accuracy is won. Every participant volunteered; nobody in any of these studies was compelled, which matters most in the workplace case, where UK law requires it. And in every case, what the result would mean was agreed before the test rather than argued about after it.
