On Weakness

No research programme can’t be improved. Sometimes sacrifices have to be made or limits imposed. Sometimes experiments or investigations don’t work out the way you hope they will. That doesn’t mean your thesis is fundamentally flawed, or your research is weak.

Still, a lot of PhD candidates ask me, “How do I talk about weakness in my viva?”

If there’s really something that could be better then you can discuss it by being honest, being clear and by talking about what’s great in your research and thesis.

  • Be honest: don’t try to hide or bluff and hope that your examiners will move on.
  • Be clear: set out the facts and your reasons, what they mean and why.
  • Talk about what’s great: not to distract, but to honestly persuade.

If there’s something you consider weak about your thesis or research, you don’t have to bring it up as you start the viva. You do have a responsibility to have thought about it and be willing to engage with your examiners. That’s no different to anything else in your research though.

You can’t write a perfect thesis. But you can’t get to the end of the PhD by accident either.

Remember: just because you think something is weak, it doesn’t mean that it is. If your examiners frame something as being weak, and you disagree, it doesn’t mean that they are right.

“Weakness” is a shorthand that people use for limitations, lack of time, doubts, worries and uncertainty. By all means consider how things could be improved or be different, but perhaps consider using a more accurate word to describe what you’re thinking about.

Blank Feels Bad…

…but it doesn’t mean something is wrong with you or wrong with the viva.

You go blank and it’s uncomfortable: doubt, anxiety or fear. It’s not that common an occurrence though.

In the unlikely event it happens, breathe. Pause. Take a sip of water. Ask yourself the question again, or think about what’s just been said. And whatever you need will come to you.

A momentary memory lapse or glitch is not comfortable, but it’s not the end of the world, even in the viva.

Pop Quiz!

The viva begins…

Quick! Ten words or less, what’s the main contribution in your thesis?

DING!

Why did you follow the methodology that you did? Hurry!

DING!

Rush, rush! What would you do differently if you started again?

DING!

…and so on.

Have you heard of a viva like this? No? Nor have I, and yet candidates worry about pausing before they answer. The viva’s not a rapid fire exam, a game show or a straight test of memory. Examiners are looking to explore, to host a discussion.

Get ready for a conversation, not a quiz.

Just Think

A Common Viva Problem: thinking you have to know and give a definitive answer to every question an examiner asks in the viva.

There may be many cases where this is impossible! While there are lots of questions a candidate can answer swiftly and completely, they do not have to do so for every request. If you’ve not considered Theory X or Idea Y before, how can you give a complete answer immediately? You can’t. So what can you do?

Just think.

Be reasonable with yourself. Your examiners don’t know everything. They know you don’t know everything. They’re asking questions for many reasons. To generate discussion. To explore. To clarify. Because they’re interested.

If you need time to think, take it. If you need to talk through an opinion, do so. Your examiners do not expect you to know everything. They do expect you to think in the viva.

Rehearsal

The mock viva is generally valuable because of the kind of practice it provides. Your supervisors might have some clear ideas about what a mock should be like. But if you think about it, the mock is a sort of test run for later success.

So think: what do you need to succeed?

  • Are you looking for certain types of questions or a particular focus for the discussion?
  • Do you want practice or pressure?
  • What kind of feedback would be most useful from the experience?

Think about what might help you. Everyone has different needs. It’s not wrong to think about how you can make the most of the opportunity.

Probing & Specific

I’ve built up a small library of notes, slides and documents about the viva from a variety of sources. On a scrap of paper I found the thought that “viva questions can be probing and specific.”

This is really worth remembering and preparing for. Your examiners are not typically looking for soundbite answers, they want explanations. A probing and specific question is looking for details and a demonstration of understanding and competence.

But that’s alright!

  • You are competent: you did the work!
  • You know the details: they might not be perfectly organised but you can take time to think.
  • The viva is a discussion: you don’t have to jump to a conclusion.

Remember too: your research and thesis are built on probing and specific questions. You’ll be able to answer similar questions in the viva.

Expect The Unexpected

Hindsight is wonderful. Before my viva I worried about whether or not I would forget things in the moment; would I be able to explain this process or that proof, things I knew really well…

…what if, what if, what if…

It never occurred to me that my examiners might ask me questions that, well, had never occurred to me.

I didn’t expect that they would ask questions about the background of my field. I didn’t expect that they would ask questions to explore things which I thought were obviously true. I didn’t expect them to question why I had included a chapter exploring a topic that had produced negative results.

I didn’t expect that they would only ask a fraction of the questions that I had expected.

Your examiners will ask you questions you could plan for, but they will probably also ask questions that you can’t anticipate – because you’re not them, you think differently, have different experiences and knowledge and are approaching the viva with a different agenda.

That doesn’t mean that you can’t be prepared for them.

  • Use the valuable opportunities of a mock viva or conversations with friends to get comfortable answering questions you haven’t considered before.
  • Read through your thesis and try to imagine how someone other than you might read it. What would they be thinking? What could they ask?
  • Realise that your examiners are not asking unexpected questions for fun: they’re exploring your work to drive the process of the viva.

It’s impossible to anticipate every question in the viva. It is possible to engage with every question that your examiners ask.

Record Your Mock Viva

I came across this tip while listening back to episodes of the podcast: if you have a mock viva, record it so that you can review it later.

Listen to check whether or not you paused to think about answers. Listen to think about whether or not there were other things you could say. Listen to see if, with hindsight, there were questions which surprised you or which you might want to practise further.

Listen to hear someone who is just around the corner from passing their viva.

Highly Unlikely

Twice recently I’ve been asked, “Is it possible to submit a perfect thesis but then fail your viva?” I’ve written about the impossibility of the perfect thesis in the past, so let’s modify it slightly: can you fail if your thesis is really good?

I wouldn’t say it’s impossible, but it’s got to be highly unlikely. Right? How do you submit a really good thesis? Only by doing really good research. You have to have built up a talent for asking and answering questions. You have to have built up a talent for doing practical research in your field. Even if you don’t like being in situations like you imagine the viva to be, you’re going to be able to meet the challenge.

Can you fail if your thesis is really good?

This question comes out of worry, anxiety and fear. Find the root concern and you can address the problem. Worried that you’re treading on an examiner’s research? Find out more about it, so that you know more. Anxious that your mind will go blank? Read your thesis carefully and make summaries to help you think it through. Afraid your examiners will have harsh comments? Ask friends about the tone of their vivas to reassure yourself.

It’s understandable to be worried. Find the cause and think about how to address it. Do that, and the question will disappear.
