Before the 2010 Gulf oil spill people on the crew had concerns about the safety of what they were doing but no one spoke up. This is an example of what?

This situation is an example of "groupthink," where the desire for harmony and conformity within a group leads to irrational decision-making and the suppression of dissenting opinions. Crew members may have felt pressured to remain silent due to fear of backlash or a belief that their concerns would not be taken seriously. This phenomenon can result in critical safety issues being overlooked, ultimately leading to disastrous outcomes, such as the Gulf oil spill.
