Big Five

The Big Five personality traits is a suggested grouping for personality traits. The theory behind the traits is one of many trait theories of personality. The five major traits are:

  • openness to experience (inventive/curious vs. consistent/cautious)
  • conscientiousness (efficient/organized vs. extravagant/careless)
  • extraversion (outgoing/energetic vs. solitary/reserved)
  • agreeableness (friendly/compassionate vs. critical/rational)
  • neuroticism (sensitive/nervous vs. resilient/confident)

With each of the factors representing a range between two extremes.

In research settings, the Big Five can be used to describe and gauge a person’s personality. Factor analysis is often applied to personality survey data in order to unearth semantic associations. These associations suggest five broad dimensions used in common language to describe the human personality, temperament and psyche.

In the world of psychedelics, researchers look for changes in the dimensions of these traits following a psychedelic experience.

Decreases in State and Trait Anxiety Post-psilocybin: A Naturalistic, Observational Study Among Retreat Attendees
This naturalistic study (n=52) assessed the effects psilocybin has on measures of state and trait anxiety among retreat participants with subclinical levels of anxiety. Average psilocin consumption across individuals was 27.1 mg. The morning after the ceremony, medium reductions in both state and trait anxiety were observed and these reductions persisted for 1-week. Higher ratings of ego dissolution and changes in neuroticism were the strongest predictors of these reductions.
