Final answer:
The exact number of participants who would leave a room filling with smoke in the presence of confederates who ignore the danger is not provided.
Step-by-step explanation:
The experiment described resembles the classic studies on conformity and obedience, such as those conducted by Asch and Milgram. When seated with ten confederates who ignored the smoke, the behavior of the actual participants in such a setup is influenced by the concept of social conformity. Based on the similar past social psychology experiments, we can infer that a significant portion of participants may comply with the group's inaction despite the potential danger. However, without specific data from the experiment described, the exact number of participants who would leave immediately is not provided.
Referring to Milgram's controversial study on obedience, it was found that a large majority, precisely 65%, were willing to administer what seemed to be lethal electrical shocks to another person under the authority's direction. This percentage talks about participants' propensity to follow orders even when they might cause harm to others. Asch's experiment on social conformity also revealed that many subjects conformed to a group's incorrect answer, further highlighting how social settings can heavily influence individual behavior.
