Type Distributions

Distribution of types in the celebrity database. Please note this may not be reflective of the general human population, as celebrities and public figures are a specific cross-section.

Understanding the Evenness Score:

To understand the distribution of different cognitive types in the database, we've implemented an "evenness score." This score provides a snapshot of how equally represented each type is within the dataset.

  1. Baseline Distribution: If every type had the same number of individuals in the database, we'd say that the distribution is perfectly even. In an ideal scenario with 16 types, each type would represent 6.25% of the total.

  2. Standard Deviation as a Measure: To quantify how far we are from this ideal even distribution, we employ a standard deviation statistical approach. We can view the standard deviation as an average of how much each type's representation deviates from the mean representation. The lower the standard deviation, the closer we are to an even distribution.

  3. Worst Case Scenario: To create a relative scale, we also consider the worst possible distribution - where one type has all the representation, and every other type has none. This gives us the maximum possible standard deviation.

  4. Calculating the Evenness Score: The evenness score is then computed as:

This formula ensures that our evenness score ranges between 0 and 1. A score of 1 indicates perfect evenness, whereas a score closer to 0 suggests significant skewness in the distribution.

In essence, the evenness score provides a quick, quantitative peek into how balanced the representation of personality types is in our database. A high score, like 0.92, suggests a fairly balanced distribution across all types
