Can You Cheat the Predictive Index Assessment?
The Predictive Index runs two tests, and each one has a different reason a shortcut fails at it.
The cognitive half is too fast to look anything up. The behavioural half asks you to describe yourself twice, and compares the two answers.
Two assessments, two separate reasons a shortcut fails
The Predictive Index is really two products, and candidates searching for a way around it usually have only one of them in mind. The PI Cognitive Assessment is a hard, speeded reasoning test. The PI Behavioral Assessment is a short self-description with no correct answers at all. They defeat a shortcut for completely different reasons.
The behavioural half asks the same thing twice
This is the part worth understanding, because it is unusual. The Behavioral Assessment presents a long list of descriptive words and asks you to work through it twice. The first pass is about how you think others expect you to behave. The second is about how you see yourself when nobody is setting expectations.
Answered honestly, the two passes have a natural relationship. Most people show some gap between the version of themselves they present at work and the version they are underneath, and the size and direction of that gap is meaningful in itself. Answered strategically, the relationship falls apart, because a candidate constructing an ideal employee constructs essentially the same person twice and produces a profile no real person generates.
The cognitive half is a pacing test wearing a reasoning test costume
Fifty questions in twelve minutes is brutal, and the difficulty is mixed rather than rising, which means an easy question can sit directly after one that would take you two minutes. The skill being measured is not really reasoning in isolation. It is reasoning plus the judgement to walk away from a question that is not coming.
Both halves reward the same underlying thing: answering as yourself, quickly, without trying to reverse-engineer what someone else wanted. On the cognitive test that is called pacing. On the behavioural one it is called honesty. They happen to be the same advice.
