Final answer:
The year 2000 consensus on the Big Five personality traits being based on genetic differences is TRUE. The Big Five model includes extraversion, neuroticism, conscientiousness, agreeableness, and openness, capturing basic dispositional traits that are relatively stable over time and influenced by genetics.
Step-by-step explanation:
The statement that in the year 2000 the scientific community reached a consensus that personality consists of basic, genetically shaped differences in dispositional traits such as extraversion, neuroticism, conscientiousness, agreeableness, and openness is TRUE. Personality traits are indeed believed to be influenced by genetics and are relatively consistent over one's lifespan. The Big Five personality factors, or the Five Factor model, encompass these traits, providing a comprehensive description of personality dimensions along a continuum.
Theory and research have evolved to a more quantitative approach, focusing on measuring these traits and how they interact to predict a person's behavior in different contexts. The Big Five factors have been recognized as a valid framework that encapsulates the range of human personality. These factors are not static but allow for individual variation within a range that is influenced by both genetic and environmental factors. It is also important to consider the cultural influences on personality, as cultural norms and values can affect the expression of these traits.
