Cattell's Sixteen Factors
Captions available
The idea
Cattell used factor analysis to reduce trait vocabulary to sixteen underlying source traits.
In practice
Thousands of descriptive words were statistically reduced to a smaller set of dimensions.
Where people slip
Factor analysis does not reveal how many factors exist. The number chosen depends on decisions the analyst makes.
