Why does the theory of planned behavior vary in its predictive ability by behavior type?​

A) ​Risk-taking behaviors are more predictable than healthy behaviors.
B) ​Situation-specific behaviors are more predictable than planned ones.
C) ​Situation-specific behaviors are less predictable than planned ones.
D) ​The theory was not designed to predict ongoing individual choices.

The theory of planned behavior suggests that behavior depends on three factors: attitude, subjective norms and perceived behavioral control. Situation-specific behaviors, which are those that are not planned and depend on the situation, are less predictable than planned behaviors. This is because the individual's attitude, subjective norms and perceived behavioral control may differ depending on the situation, making it harder to predict their behavior. Planned behaviors, on the other hand, are more predictable as the individual has made a conscious decision to engage in the behavior and their attitude, subjective norms and perceived behavioral control are likely to remain consistent.
