Personal fit

Personal fit is a measure of a person's chances of excelling in a particular job.

Formally, personal fit it may be defined as the ratio of the person's productivity in the job to the average productivity of other candidates likely to take that job. Personal fit is one of the factors in 80,000 Hours' original career framework, as well as a key element in their current list of strategic considerations (Todd 2019).

Personal fit measures a person's absolute advantage in a job. But a person's comparative becomes relevant when coordination is feasible. In such cases, a career with lower personal fit may have a greater community impact (Todd 2018: sect. 3).
