When a presentation is delivered to a large group, important information can get lost.
The information often needs to be reworded and repeated for the group to understand it. This could be resolved by any one of them asking the presenter to repeat their point. However, given that the group is large, it is awkward to admit one’s ignorance. The bigger the group, the larger is the probability of information getting lost. But the bigger the group, the more hesitant people are to ask a ‘stupid’ question.
It take courage and generosity to interrupt a presentation. If we haven’t understood something, we are often not alone, and we are doing everybody else a service.
