Self-Deception Test

A subtle scenario-based assessment of how reasoning changes when reality becomes personally inconvenient. It measures motivated reasoning, selective evidence, rationalisation, responsibility distortion, feedback resistance, hidden motives and other ways people protect preferred beliefs or self-images.

Answer with what would genuinely go through your mind. The test is not looking for confession, modesty or self-criticism; automatically blaming yourself can be just as inaccurate as automatically excusing yourself.

The scoring looks for whether your standards, evidence or explanations change when a conclusion becomes personally convenient or inconvenient. Mixed motives and ordinary defensiveness are normal and do not automatically score highly.

All 30 questions contribute to the self-deception profile. The same answers are also scored against the personality dualities in the background.

Question 1 of 30

You buy something expensive after weeks of wanting it. Afterwards you find yourself explaining that it was mainly a sensible investment, even though that was not what excited you beforehand. How would you interpret your explanation?

Question 2 of 30

You argue passionately for a principle in a disagreement. Later you realise that winning would also make you look competent in front of people whose opinion matters to you. What does that do to your confidence in your own reasoning?

Question 9 of 30

Not saved yet

Not saved yet

Not saved yet

Not saved yet

Not saved yet

Not saved yet

Not saved yet
