B: Can a presenter really change his/her image from presentation to presentation? If so, how? Is it ethical? Try to think of an example in which this might happen or has happened. What are/were the results?

Presenters are constantly trying to represent themselves as experts of the knowledge they are conveying to their audience. Often, the topics presenters must cover vary by the needs of the business being represented, conference agenda, and audience. As topics vary, the depth of presenter knowledge also varies. In attempt to gain credibility, the presenter may make attempts to boost their image as a subject matter expert....

I've seen speakers use references to organizations and companies that give the illusion that the speaker is somehow affiliated with them or has specialized knowledge that they don't actually have. I've also seen speakers change their job titles from presentation to increase credibility and try to mask the fact that they are giving a vendor pitch rather than impartial commentary. and, I've also witnessed speakers trying to "wing" answers to questions when it's apparent that they have no idea what they are talking about. This type of behavior is not ethical and, typically, the audience sees behind the facade and is not receptive to the presenter.
