What integrity signals are and why a person reviews them

Integrity signals are observations recorded while an assessment is being taken —snapshots, location, response times, facial behavior— that provide context about how the test was taken. Their purpose is to support the human review of the result: none disqualifies, diagnoses, or decides on its own. A person interprets them in context, and the final decision is always theirs.

Which signals are recorded

During the assessment, with the candidate’s consent, signals like these are recorded:

• Camera snapshots. Around eight captures per test, to verify it’s the same person.
• Location by IP. A reference for where the test is taken.
• Response time and latency. The pace at which answers are given adds context.
• Facial behavior. Observations drawn from the snapshots —attention to the screen, gaze direction, predominant expression— that support the human review.

Each one is a partial data point. Its value lies in the whole and in how a person reads it.

Why a person reviews it and not a system

An isolated signal almost always has more than one explanation. A gaze that drifts may be nerves or a legitimate distraction. A long pause may be reflection. An IP change may be an unstable network. That’s why no signal should disqualify automatically: only a person can read it in the context of the candidate, the role, and the rest of the information.

If the system decided alone	If a person reviews
One signal = verdict	One signal = context to interpret
Risk of unfairness	Room to understand the case
Black box	Explainable decision

What the signals are not

It’s worth being explicit, because this is where the most common misuses are:

• They are not fraud or lie detection. They don’t determine cheating or bad faith.
• They are not a psychological diagnosis. Facial behavior records observations, not traits or internal states.
• They don’t disqualify automatically. No one is in or out because of a snapshot.

Their only role is to give more context to whoever reviews, always with the candidate’s consent.

In short

Integrity signals are observations recorded during the assessment that provide context about how the test was taken. They don’t detect cheating, don’t diagnose, and don’t disqualify: they flag what’s worth reviewing. A person interprets them in context and decides, always with the candidate’s consent.
