Derrick's confidence is based on the misconception that communication maximizes understanding.
Communication refers to the transfer of message or information between the sender and receiver using both verbal and non-verbal cues that are understandable to both parties.
However, being a good communicator means that one has enough confidence to speak and pass messages to an audience. But to aid effective communication especially that which is targeted at a specific audience , it is imperative that one prepares for such.
In Derrick's case, he feels confident speaking without preparation because he feels that communication is an art and once one becomes good at it, one has attained perfection.
However, it is also imperative that one is very conversant with the subject one is speaking about in other to ensure that good and useful knowledge is passed on to the audience.
Hence, Derrick's misconception is that since he is already a good communicator, his understanding has been maximized and hence, he does not need to prepare for speeches.
