Line 81:
The lines had an average of six people waiting. The experimenter calmly approached a point between a 3rd and 4th person in line and said in a neutral tone "Excuse me, I’d like to get in here.” Before anyone in the line could respond, the intruder cut in line and faced forward. If the experimental intruder was directly admonished to leave the line, he or she did so. Otherwise, the intruder stayed in the line for one minute before departing. Three female and two male graduate students acted as intruders, with an observer watching nearby to record physical, verbal, and nonverbal reactions to the intrusion. The experiment manipulated conditions by having either one or two intruders break into the line, as well as varying one or two buffers, or experimenters standing passively by in the line. This enabled the researchers to test whether the responsibility of addressing the intruder would extend from the person closest behind in line to the rest of those in line.
 
Broadly, results indicated that others in line objected with greatest frequency (91.3%) when there were two intruders and no buffers. One intruder and no buffer resulted in the next highest frequency of objections (54%). The least amount of objection (5.0%) occurred when there was only one intruder and two buffers. Thus, objections occurred most frequently when there were more intruders and fewer buffers. The researchers noted the following rates for each type of objection: physical action (10%), verbal interjections (21.7%), nonverbal objections such as dirty looks, hostile stares, and gestures (14.7%).<ref name=response /> Verbal responses were the most common, with comments such as, "No way! The line's back there. We've all been waiting and have trains to catch".
 
As reported in Milgram's subway study, experimenters in this study also experienced a high level of [[negative emotion]] associated with the task of intrusion into lines. Experimenters described feeling nauseated, anxious, and struggling to get up the "nerve" to intrude in a line. Milgram reasons that these feelings make up the "inhibitory anxiety that ordinarily prevents individuals from breaching social norms" and indicate that the internal restraints against intruding into lines play a significant role in assuring the integrity of the line.<ref name=response />
