There’s always a chance you’re wrong about something. There’s always a possibility your examiners believe you’re wrong. Until they ask they won’t be able to know either way.
Being wrong or being asked something because you might be wrong is not comfortable. It invites all sorts of feelings and worries.
Did you make a mistake in your research? Did you write something up incorrectly? Did you misunderstand? Were you unclear?
- You’re not perfect.
- Your research can’t be perfect.
- Your thesis won’t be perfect.
There’s a chance that you’re wrong in some way but a much greater chance that if you are then you can make it right.
You can do the work. Do the work in your prep to figure out how to correct things. Do the work in the moment in the viva to clear up what you mean. Do the work while you talk to your examiners to explain something. Do the work to correct your thesis after the viva.
You might be wrong, that’s human – as is working to make things right.
