How the test was built
65 of the 72 statements come from the International Personality Item Pool, a public research inventory; the other seven are new and belong to the sixth scale. Each scale has 12 statements. On five of the six scales your answers are compared with more than 135,000 people from Johnson's IPIP-NEO data; the sixth scale is still provisional. Read the method page.
How the type pages are written
Every type page has two layers. The letters come from the scales and are measured. The descriptions, scenes and advice are editorial interpretation of what those scales mean in daily life; they are not findings about people with a given code, and no professional body has reviewed them. Where a page states a number, the method page or the article it links to shows where the number comes from. The shares shown in the rarity figures are the exception: they are counted from the reference group.
