Examining since 2009

The Polygraph Examiner Behind Every Report

A polygraph examiner is the whole service. The instrument records, but a person builds the questions, runs the consultation and reads the chart. This page is about the person who does that here, and what he trained on before he did.

Where this came from

Eighteen years asking questions, before the first chart

Spot on Polygraph was established in 2009 by Steven Steyn. What came before it matters more than the date.

Steven served in the South African Police Service from 1990 to 2008, and spent that service as an internal investigation officer. Internal investigation is the hardest interviewing there is: the subject is a colleague, the room already knows the story it wants, and the officer asking has to keep going anyway. Eighteen years of it is where the questioning came from, and it is the part of this practice that no instrument supplies.

He resigned from the SAPS in 2008 and spent a year studying in the security industry in New Zealand. He came back to South Africa in 2009, moved into lie detection, and founded the practice the same year. Every qualification since has been added on top of that, not in place of it.

The practice has grown into a team, and it now covers investigation and labour work alongside the examinations. The standard has not moved: the examiner travels to the client, sits with the person before anything is switched on, and puts the findings in writing.

What it means for you

A qualification is only worth what it changes

Four things follow from the record above, and they are the four you will actually notice.

The questions are built, not picked

Eighteen years of internal investigation is eighteen years of learning which question actually gets at a thing and which one only sounds like it does. Your examination is written for your matter.

Findings that survive a hearing

An examiner who came out of policing knows what a finding has to look like to be usable. The report is written to be put in front of someone else, and the examiner can speak to how it was produced.

A team, trained to one standard

Instructor level is the qualification to train other examiners, so the team is not a set of people who happen to work together. They were brought to the same standard on purpose.

Nobody is ambushed

The consultation happens before anything is switched on, and every question is worked through in it. Nobody is tested on a question they have not already seen.

How we work

Four things that do not get negotiated

  • The code of ethics, individually

    Every examiner holds to the code of ethics of the American Polygraph Association in their own name, not under the practice's. It is not a badge on a website, it is what governs the room.

  • The civil rights of the person tested

    Whoever is paying, the person in the chair has rights, and they hold for the whole examination. That is stated here because it is the first thing a badly run test gives away.

  • One client, one report

    Results go to whoever commissioned the examination and to nobody else. Private matters are booked directly with you and reported directly back to you.

  • In writing, or it did not happen

    Every engagement ends in a document rather than a phone call, and the quote that opened it was written too. Nothing about this practice runs on what somebody remembers being said.
