This is contrary to the common sense belief that groups tend to be more conservative than their individual members. Complete the questionnaire again individually. The risk of failure is spread around. If someone gets injured as a result, no one individual can be held responsible. The risk was a group decision.
People lose their sense of self-awareness and individuality in the group context.
As with group polarization, this can be positive or negative, depending on the values and principles of the group. When team members compromise to achieve goals consistent with their organization's purpose and mission statement, the effects of deindividuation are likely to be beneficial. But deindividuation can lead to abandoning fundamental individual constraints and to less careful or less safe decisions and behaviors. Deindividuation is facilitated when group members wear uniforms and cut their hair in similar ways, as in prisons, cults, monasteries, and the military. Work teams certainly don't experience this degree of deindividuation.
