This study is observational. There are a number of possible confounding factors. One confounding factor may be the subject’s personality type. If subjects are able to choose whether to make a decision immediately or deliberate, subjects that are considered “leaders” who have strong decision-making skills may be more inclined to opt to make a decision immediately, while less leadership-inclined individuals may be more likely to deliberate their decision.

If the study were to be redesigned, subjects should not be given the option of how they want to make a decision, but rather half be told to make an immediate decision and the other half to make a deliberate decision.
