In the present study, we investigated the influence of the presence of others and goal support on the performance of goal-directed behavior across different levels of self-control. Our analysis included survey data from 3,972 respondents across four countries. The results of the analysis revealed four important findings. First, high goal support increased the performance of goal-directed behavior when in the presence of others during decision-making. Second, self-control had a positive effect on goal-directed behavior only when individuals were by themselves. Third, while the effect of goal support significantly increased goal-directed behavior independent of self-control ability, people with low self-control reaped the most benefits from having goal support. Finally, we observed that although people with low self-control gained the most benefits from goal support, they were also less likely to be positioned in goal-supportive environments.
