How Personality Predicts Success in Different Fields

Main summary

Key takeaways

Science and Nature

Scientific concepts and nature of phenomena presented

Personality structure and measurement

  • Self-descriptive adjective ratings: Large groups (e.g., ~1,000 people) rate how well adjectives describe them (e.g., happy, social). The key idea is that these ratings reveal covariation patterns.
  • Factor-analytic “essential dimensions” of personality: Covariation among trait-descriptive adjectives can be used to infer underlying personality dimensions.
  • Big Five–like dimensions mentioned:
    • Extraversion / happiness-like positive emotion: Higher self-rated happy tends to co-occur with higher self-rated social.
    • Neuroticism / negative emotion: Negative emotions “clump together” (e.g., anxiety and sadness co-vary positively).
    • Agreeableness: Described as self-sacrificing, compassionate, polite, conflict-avoidant, cooperative, and oriented toward others’ concerns.
    • Conscientiousness: Diligent, industrious, orderly; linked to better school/work performance.
    • Openness: Associated with creativity, aesthetics, novelty, and fiction/art/music; correlates with intelligence/IQ and with liberal political orientation (as stated).

Cross-cultural and gender differences

  • Agreeableness gender differences: Women score higher than men on agreeableness across cultures, including more egalitarian societies (e.g., Scandinavia). The claim is that gender differences may be larger there than elsewhere.

Personality–politics linkage (mediation via beliefs)

  • Personality predicts political beliefs more strongly when belief measures are more accurate.
  • Proposed mechanism: personality shapes how people simplify the world, which then influences what they believe and how they vote.
  • Orderliness → political conservatism: Orderliness is described as one contributor to this pathway.

“Temperament matching” to environments

  • Niche theory / person–environment fit:
    • People occupy niches where their skills match environmental demands.
    • Extraverts seek social opportunity; introverts seek retreat/alone time.
    • Success depends partly on whether temperament matches environmental demands, and whether society provides niches for that temperament.

Evolutionary distribution idea

  • Traits (e.g., extraversion) are described as having distributions (roughly “normal distribution”).
  • Having fewer people at extremes suggests environments may often match the center, but sometimes match extremes too.
  • Example (hypothesis, not claimed proven): In a tyrannical society, being highly extraverted (high sociability) and low in neuroticism might be maladaptive because it increases visible sociability and reduces inhibition.

Conscientiousness details and learning/scheduling implications

  • Conscientiousness correlates with grades:
    • Correlation with university grades: ~0.4, claimed to explain ~16% of variance.
    • Reported as the second-best predictor after intelligence.
  • Orderliness and disgust sensitivity:
    • Orderliness is associated with disgust sensitivity (e.g., messy environments trigger disgust and a desire to clean/organize).
  • Industriousness biology/psychology unknown:
    • The speaker reports difficulty finding lab measures or animal models that map directly onto industriousness.
    • Industriousness is framed as involving sacrificing present for future, implying the need to conceptualize time.

Learning methodology and memory (applied cognition)

Scheduling to avoid cramming

  • Treat the semester like a job.
  • Use a calendar/scheduler (e.g., a semester calendar / Google Calendar) to improve follow-through.

Spacing and sleep

  • Study in spaced sessions, with sleep, to improve remembering.

Recall practice vs recognition

  • Highlighting and “go over material” are described as less helpful.
  • Preferred strategy: close the book and summarize from memory to practice recall, not just recognition.

Creativity and distribution of creative ability

Openness and creativity

  • Openness/creativity is tied to novelty and aesthetics.

Creative Achievement Questionnaire (CAQ)

  • The CAQ measures creativity across 13 dimensions (examples include writing, dancing, acting, scientific investigation, entrepreneurship, architecture, cooking, singing, etc.).
  • Participants rate self-achievement from 1–10, with 0 indicating no training/proficiency.
  • Reported finding: ~70% score 0 on the CAQ, with a smaller group much higher.

Pareto-like distribution claim

  • Creativity achievement follows a Pareto-like pattern: many near zero, a few far above.
  • Comparison: this resembles money distributions, where a small fraction holds most wealth.
  • Aging claim (as stated): being in the high-performing “tail” becomes more likely because people trade youth for money.

Lists and methodology outlined

Personality dimension discovery via adjective covariation

  1. Collect self-ratings on many adjectives describing the self.
  2. Identify co-variation patterns among adjectives.
  3. Infer latent personality dimensions from those patterns.

Study strategy described (conscientious/industrious practice)

  • Create an upfront schedule (e.g., semester calendar / Google Calendar).
  • Align the plan to upcoming assignments/exams.
  • Prefer spaced study over one prolonged cram session.
  • Use active recall: close the book and summarize without looking.
  • Avoid relying mainly on highlighting/re-reading.

  • No specific researcher names are provided.
  • No external publications are explicitly cited.
