=== Lower-order factors ===
[[File:Factors.svg|thumb|right|250px|Similarities between lower-order factors for psychoticism and the [[Facet (psychology)|facets]] of openness, agreeableness, and conscientiousness (from Matthews, Deary & Whiteman, 2003)]]

There are two higher-order factors that both taxonomies clearly share: [[extraversion]] and [[neuroticism]]. Both approaches broadly accept that extraversion is associated with [[sociability]] and positive [[dispositional affect|affect]], whereas [[neuroticism]] is associated with emotional instability and negative affect.<ref name="Personality traits">{{cite book|last1=Matthews|first1=G.|last2=Deary|first2=I.

Many lower-order factors, or [[Facet (psychology)|facets]], are similar between the two taxonomies. For instance, both approaches contain factors for sociability/gregariousness, for activity levels, and for assertiveness within the higher order factor extraversion. However, there are differences too. First, the three-factor approach contains nine lower-order factors and the five-factor approach has six.<ref name="Personality traits"/>

Eysenck's [[psychoticism]] factor incorporates some of the [[orthogonal|polar opposites]] of the lower order factors of openness, agreeableness and conscientiousness. A high scorer on tough-mindedness in [[psychoticism]] would score low on tender-mindedness in agreeableness. Most of the differences between the taxonomies stem from the three factor model's emphasis on fewer high-order factors.
