Expectancy-Value Theory: Why You Try (or Don’t)

The two-factor model of motivation and how to intervene on each factor specifically

Why do people pursue some goals energetically and avoid others even when they care about the outcome?

Jacquelynne Eccles’s expectancy-value theory proposes that motivation to pursue a task is jointly determined by two factors: expectancy (your belief that you can succeed) and value (how much you care about success). Both are required — high value with low expectancy produces anxiety and avoidance; high expectancy with low value produces competent indifference. The theory has a substantial empirical base primarily in academic achievement contexts, with reasonable generalisation to broader life domains.

Most motivation advice treats "motivation" as a single variable to increase. Expectancy-value theory, developed by Jacquelynne Eccles and colleagues through decades of research on academic achievement, decomposes motivation into two distinct factors that require different interventions. Knowing whether you are stuck on "I can’t do this" versus "I don’t care enough about this" determines which lever to pull. The practices below are grounded in Eccles’s published framework, with honest notes on what is directly evidenced versus applied.
