I had an idea for explaining the PhD process, a picture in my head that I described to my wife:
Me: “PhD candidates are like salmon, swimming upstream to the source of ideas. It’s a difficult journey, long and tiring, but at the end-”
Mrs R: “They’re eaten by bears? Are examiners like bears?”
Me: “Erm, no. Well, I guess you could say-”
Mrs R: “I think a lot of salmon don’t make it. I’m sure I read that. Swimming against the current kills some salmon just for trying.”
Mrs R: “And then some of the salmon that make it get eaten. By bears.”
There are lots of metaphors and analogies that work in describing the PhD journey and the viva. They’re useful because they give us something to hook into. They can set expectations or help us through tough times. Find one that helps you.
But please don’t be a salmon.
