One strength of the situational variables of obedience is that Milgram's findings have been replicated across cultures. A researcher used a more realistic procedure than Milgram's to study Dutch ppts. Ppts were ordered to say stressful things in an interview to confederates who were desperate for a job. Findings show that 90% of ppts obeyed. Additionally, a researcher replicated Milgram's variation of proximity. Findings show that when the person giving the orders was absent, obedience decreased.
