How percentiles are computed
Category percentiles use a normal CDF against population mean and standard deviation. Your percentile answers: 'What fraction of our sample scored below this?'

FAQ
Are these averages representative of the global population?
They represent Imagination Index assessment takers—people who reached our site and completed a full six-sense profile. This sample skews more curious about cognition than the general population. Treat percentiles as 'compared to this engaged sample,' not as universal anchors.
Why is overall mean ~49 rather than 50?
Overall is a composite across all six senses; smell and taste average notably below 50 in this sample, which pulls the overall mean slightly under the midpoint. The exact value updates as new responses come in.
