Syllabus: How Should We Understand Personality?
Compare stable aggregate differences with variation in reported states. Then ask what a distribution retains and what it loses about the situations in Mischel and Shoda's account.
Why you’re reading it. Connect a process question with a feasible method for studying daily experience, while separating description from explanation.
A question to consider. If Sam and a colleague have the same mean sociability but different spreads, what situational information would help explain the difference rather than merely redescribe it?
Why this reading
A broad trait need not mean acting the same way throughout the day. Fleeson uses repeated reports of everyday states to show how substantial variation within a person can coexist with reliable differences between people. The distribution of someone's states becomes an object of study, rather than treating every departure from an average as noise.
Before you read
A state describes how someone is acting or feeling at a particular time. Experience sampling collects repeated reports during daily life. A density distribution summarizes how often different state levels occur; its average and spread describe different features. Keep variation within one person separate from differences between people's averages.
Read for
- Follow how repeated state reports become a distribution and how the paper assesses the reliability of its characteristics.
- Compare the amount of within-person variation with the consistency of aggregate differences between people.
- Examine the reporting schedule, self-report measures, missing observations, and sampled situations before interpreting what the distributions represent.
Consider afterwards
- Two people have the same average sociability, but one stays near that average while the other ranges widely. What information would an ordinary trait score miss, and what would you need to know before explaining the difference?
Editorial context
The three studies concern repeated self-reports over weeks, largely among students. Reliable aggregate patterns over those observations are not evidence of stability over decades. State adjectives are reports rather than independent observations of every behavior, and associations with situations do not by themselves establish causes. The paper provides a bridge between trait descriptions and everyday variation; it does not supply a complete theory of why each state occurs.
