Q: Does anybody listen to the speaker?
Here is a mathematical answer: only 18.5% of the audience listens to more than 31% of a speaker. Only 4.86% of the speakers listens to other speakers for more than 27% of the time. But when the speaker refers to the work of another speaker, the speaker referred to listens to at least 58% of the talk. Listeners — whether speakers or not — decide within the first 2.86 minutes whether to concentrate on the talk or not. If a listener decides that the theme of the talk is ideologically variant with her, then she completely stops listening after 3.42 minutes.
So who is the speaker really speaking to?
