Is expectancy in Vroom's expectancy theory synonymous with subjective probability?

Expectancy in Vroom's expectancy theory is closely associated with the individual's belief in the likelihood that their efforts will lead to desired performance levels. This concept can indeed be likened to subjective probability, as both involve personal judgment regarding how likely a particular outcome is based on an individual’s experiences, perceptions, and observations.

In Vroom's model, expectancy specifically reflects a person's assessment of the relationship between effort and performance; if someone believes that by exerting a certain level of effort, they can achieve a desired performance outcome, then their expectancy is high. This subjective evaluation is influenced by various factors, such as past experiences and the perceived difficulty of the task.

Therefore, since expectancy reflects this individual perception of probability regarding the success of their effort leading to performance, it can be seen as synonymous with subjective probability.
