I have read in a few places, for example here, that a 20-minute presentation (or indeed, any presentation at a conference) is an advertisement for the paper or research program in question. I had never thought of it this way and have tended to worry that I have not been technical enough. I now see that this is probably a mistake.
I want to incorporate this advice, but I'm still faced the problem of determining the best way to translate a full-length paper into a 20 minute presentation. That is to say, I want to get some idea of the process by which a paper is "converted" into an "advertisement" for presentation. I am wondering about which of the following, for example, is advisable:
- Presenting all of the arguments and objections in the paper, but in a more surface way.
- Limiting the paper to a few key points.
- Leaving certain questions open by spending more time motivating the question and then suggesting or gesturing at the answer that the paper gives (this fits with the idea of an advertisement).
I realise that answers will likely take be "all of the above" or "it depends", so really what I'm interested in are additional suggestions, some idea of priorities, and some way of figuring out given the situation how to make the decision.
P.S. My discipline is philosophy.
