Week 5: Personality and Consequential Outcomes Flashcards
Why might personality predict life outcomes
Direct effects — from the general to the particular
Indirect effects — statistical mediation ’ – where some intervening variable or process forms a link in the chain between personality & outcome. E.g. via situation selection
Interactive/conditional effects — person x environment interactions
History of prediction: The Lexical Hypothesis
- important personality characteristics will, over human history, be coded in language.
§ Personality characteristics will be important if they enable us to make predictions about what other individuals are going to do.
§ For example, who might help us, who might hurt us, who will offer leadership, who is reliable
Formal assessment of personality and abilities…
•Educational contexts
•Binet and Simon (1905, 1908, 1911): identification of children who may benefit from alternate education…
•Development of the Scholastic Aptitude Test (SAT) in 1926
Formal assessment of personality and abilities
•Occupational contexts
•Military selection and placement under Robert Yerkes (1915)
•1950s-1970s: Diversification and mobility of work
•Growth of Human Resources Management
The Prediction of Achievement
Job Performance
•Schmidt & Hunter (1998) conducted a meta-analysis of 85 years of research
•Predictors included abilities, personality traits, work experience, references, etc.
•Criterion was job performance—typically measured in terms of supervisory ratings (but other indicators too – e.g., sales records)
Result from Schmidt & Hunter (1998)
•Years of education, r = .10
•Job experience (years), r = .18
•Reference checks, r = .26
•Employment interviews, r = .38-.51
Personality…
•B5 Conscientiousness: r = 0.31
•‘Integrity tests’ (blend of C & A):r = 0.41
Conclusion from Job Performance prediction
•Strongest individual differences predictor was cognitive ability(or ‘intelligence’)…
•But… personality adds to predictive validity of cognitive ability…
ØCognitive ability alone; r = .51
ØCombining cognitive ability with conscientiousness; R = .6o
ØCombining cognitive ability with an integrity test; R = .65
Achievement at Work
Barrick& Mount (1991, 1998):
•Meta-analyses focussed just on the big five:
•Conscientiousness predicts performance across all occupations: r = .20-.23
•For effort-related (as opposed to skill-related) criteria:r = .42
•Extraversion predicted performance well in two specific job areas:
•Management: r = .18
•Sales: r = .15
Achievement at Work
Hurtz& Donovan (2000):
•Updated meta-analysis to check replicability of earlier findings…
•Key findings:
•Conscientiousness again predicts broadly (r ~ .20)
•Agreeableness, Openness/Intellect, and (low) Neuroticism predicts performance in customer service roles
•Extraversion and (low) Neuroticism predicts in management and sales roles
Achievement at Work
Wilmot & Ones (2019):
•A recent meta-synthesis focussed on conscientiousness and job performance…
•Combined 2,500 individual studies
•Total of >1.1 million participants
•Examined a broad range of performance related criteria
•Overall relation between C and performance: r~ .20
•Stronger in jobs characterised by lower occupational complexity.
Achievement at Work
“Occupational success”
•Indices typically reflect popular views of job desirability or ‘prestige’, related to wages, years of education required, etc.
•e.g., ‘Duncan’s Socioeconomic Index’ (Duncan, 1961)
•Typical top scorers include Doctor, Dentist, Lawyer, etc.
•Predictive validity for
•Openness/intellect: r = .18 (Sutin et al., 2009)
•Extraversion: r = .16 (Roberts et al., 2003)
•Conscientiousness: r = .15 (Roberts et al., 2003)
® Personality predicts various indicators of occupational success (income, promotion etc.) up to 47 years later.
Educational Achievement predicying factor
•Educational performance (Grade Point Average; GPA)
•A combination of cognitive ability and conscientiousness predicts achievement across programs (Kuncel et al., 2001)
Educational Achievement Poropat (2009):
•Predicting school/university GPA from…
•Cognitive ability: r = .25
•Conscientiousness: r = .22
•Openness/intellect: r = .12
•Agreeableness: r = .07
•Of personality measures, only conscientiousness adds to prediction above cognitive ability
Educational attainment predictor
•e.g., highest level completed / years spent in full time
education
•Strongest B5 predictor is openness — r ~ .35
How does openness preiducit education achivement
•Openness also predicts…
•intrinsic motivation (interest and enjoyment of study topics) in university students; r ~ .35
•breadth/depth of reading; r ~ .25
Educational Achievement
Choice of college major…
•Extraversion; Economics, Law, Political Science, and Medicine
•Neuroticism; Arts, Humanities, and Psychology
•Agreeableness; Medicine, Psychology, Sciences, Arts, and Humanities
•Conscientiousness; Science, Law, Economics, Engineering, Medicine, and Psychology
•Openness/Intellect; Humanities, Arts, Psychology, and Political Science
Why does conscientious personality predict achievement?
- Direct effects: Conscientiousness predicts most strongly for effort-related criteria
- Indirect effects: conscientiousness and extraversion predict ‘occupational success’ (higher wages etc.) viachoice of major (e.g., law)
- Interactive effects: extraverts may respond well to the interpersonal challenges of leadership and management roles
Indirect effects on educational achievement via study strategies Conscientiousness
Corker et al. 2012:
•Conscientiousness assessed in 347 US college students at the beginning of semester
•Various study strategies assessed the week before exams, e.g.,
•Deep processing (e.g., “I try to think through topics…”)
•Persistence (e.g., “…I work my hardest to learn it”)
•‘Achievement’ based on exams and coursework
•Use of effortful study strategies explained the relation between conscientiousness and educational achievement
