Making Vs Having
I feel that many PhD candidates expect they will have to argue a lot in the viva.
Arguing can feel like a loaded term. There are lots of negative associations with the word argument so we need to be clear for viva expectations.
The viva is supposed to be a discussion. Maybe you need to make an argument – presenting ideas and evidence and reasoning – but there should never be a situation where you have an argument.
The idea of having an argument is persistent. Some candidates expect that they will be countering points and questions that their examiners put forward. They feel they will defend their thesis by protecting what they have done and what they have written.
At times you might need to make an argument in the viva: make a case, lay out your thoughts and reasons. Put your view across and listen for your examiners’ thoughts.
Don’t expect that you’ll have to have an argument to be heard.
