Mаrissа wоnders if experiencing pоsitive behаviоr makes people nicer. She sets up an experiment where the experimental group of participants receives a small free gift in front of the campus union during a busy time of day (e.g., lunch), whereas the control group does not receive the gift. She has research assistants watch the participants to see who opens the door for others. She conducts this study on a Thursday during lunch, and gives gifts to the first 50 people she sees, until she runs out of gifts, and then watches 50 more people for her control group after that. What is the main factor preventing Marissa from being able to state that receiving a gift causes shifts in acting nicely towards others?
