How accurate are Blueprint's tests?
No predictive model is 100% accurate. That said, our initial testing has suggested that we’ve built one of the most accurate and predictive Enneagram models available on the market. We are continually working to heighten its accuracy.
Your results are expressed as a percentage, with the Enneagram type that has the highest probability of matching you at the top. The percentage expresses the likelihood that you belong to a certain personality type, or “cluster.” For example, if your results say that you’re 94% type Eight, 67% type One, and 59% type Three, that means that the test found that there’s a 94% probability that you’re an Eight, a 67% probability that you’re a One, and a 59% probability that you’re a Three. It does not mean that you’re made up of a mix of these types, nor that you’re an Eight with a One wing (which can’t exist in the model; see our FAQ answer on wings to read more about this).
All personality test outcomes depend on the test-taker’s self-awareness and honest self-assessment: the better you know yourself, the more accurate your results tend to be. Colloquial wisdom suggests that about 80% of people know themselves well enough to answer self-assessment questions in ways that accurately reflect them. Research has shown that introspection, mindfulness, and self-reflection can improve your self-awareness (and thus the accuracy of your test results). Asking people who know you well to chime in on their perception of your behavior--romantic partners, family, coworkers, and others who you spend lots of time with as your “real” self--has also been helpful according to studies, given that your behavior is outwardly observable even if your motivations are internal and non-observable.
