From Wikipedia:

In psychological trait theory, the Big Five personality traits, also known as the five-factor model (FFM) and the OCEAN model, is a suggested taxonomy, or grouping, for personality traits,[1] developed from the 1980s onwards. When factor analysis (a statistical technique) is applied to personality survey data, it reveals semantic associations: some words used to describe aspects of personality are often applied to the same person. For example, someone described as conscientious is more likely to be described as "always prepared" rather than "messy". These associations suggest five broad dimensions used in common language to describe the human personality and psyche.[2][3]

The theory identifies five factors:

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

The five factors are abbreviated in the acronyms OCEAN or CANOE. Beneath each proposed global factor, there are a number of correlated and more specific primary factors. For example, extraversion is typically associated with qualities such as gregariousness, assertiveness, excitement-seeking, warmth, activity, and positive emotions.[4]

Family life and upbringing will affect these traits. Twin studies and other research have shown that about half of the variation between individuals results from their genetic inheritance and half from their environment. Researchers have found conscientiousness, extraversion, openness to experience, and neuroticism to be relatively stable from childhood through adulthood.[5]
