Good judgement is one of the most valuable qualities in management in general and leadership in particular. But how do you know if yours is up to scratch? And what can you do to improve it? Sir Andrew Likierman, former Dean of LBS, has been examining how to answer these questions. In his new book Judgement at Work: Making better Choices, he distils the results of his work on how you can improve your own judgement and recognise it in others.
Understanding how to make the most of your own judgement – both in a work context as well as in private life – is a subject that has interested Sir Andrew from an early age. He recalls that his grandfather moved countries twice to avoid persecution, the second time to England aged 60, even though did not speak the language. “His qualities, including his judgement in anticipating problems, always impressed me”.
But the spur to his current work stems from his earlier research on performance measurement, particularly the challenge of assessing things that are difficult to measure. “Judgement is really significant in making choices,” he commented.
So how do you know if someone has good judgement? “Bad judgement is obvious when things go wrong but identifying good judgement has always been seen as more elusive. I’ve worked in many different environments and seen first-hand how critical good judgement is in each of them.”
These environments are indeed diverse. His career spans commercial, public and academic sectors, including working in Australia, Germany, the UK and the US. He has been Head of the UK Government Financial Service, Director of the Bank of England and Chairman of the UK National Audit Office and was knighted in 2001 for his services to the public sector. It is this background of diverse experience, together with more than 800 interviews and a search across many different literatures, that has provided the foundation for the book.

"Bad judgement is obvious when things go wrong but identifying good judgement has always been seen as more elusive"
"There’s a vast body of work on decision-making, but very little that focuses specifically on judgement. There’s not even clarity about how to define it,” said Sir Andrew.
This realisation set him on a voyage of discovery. What he found from his search of literature and interviews was that one of the reasons judgement isn’t studied is because it’s so difficult to research. If each judgement is context-specific it’s difficult to apply statistical techniques. “Also, it’s a subject that crosses many disciplinary boundaries, making it challenging to publish in academic journals.”
So what exactly is judgement? Sir Andrew defines it as “the combination of personal qualities with relevant knowledge and experience, either to make decisions or to form opinions.” It’s not just about decisions, he adds: “We make judgements when we form opinions too.”
The framework to enable judgement to be used as a process is set out in the book. He described the six elements below.
Sir Andrew particularly emphasises the dangers of overconfidence in judgement. “Being optimistic is one thing and generally people know if they have a tendency to be overoptimistic. You might even need someone in your team who you trust who brings a more cautious perspective. But overconfidence is quite another matter. It’s particularly dangerous because it means people overestimate what they know, don’t take in what’s going on around them, don’t bother to consult, take bigger risks than they should and so make poor choices.”
So how can organisations cultivate a culture that values good judgement? Sir Andrew suggests integrating judgement into hiring, appraisal and promotion. “When hiring, assess a candidate’s judgement as well as their other qualities. After all, you are going to have to work with them and having someone in your team who has no judgement is, frankly, a nightmare. During annual appraisal, provide feedback on elements of the judgement framework where they can improve, for example gaining more experience in a new area or understanding the dynamics when choices are made in a team or group.”
He also highlights the importance of diversity in decision-making. “You need people who can challenge accepted ideas and can provide diverse perspectives to stop getting stuck in a particular way of thinking. Bad judgement can also mean a missed opportunity because nobody thought about including a crucial option.”
In an era where artificial intelligence is increasingly used to aid decision-making, Sir Andrew argues that human judgement remains indispensable. “AI can do many wonderful things and perform many tasks far better than humans. But human beings are more than machines with brains which are collections of neurons. So there are limits to what a machine can do - you can’t outsource morality for example. And because judgements are context specific, it’s unrealistic to expect AI to be able to exercise judgement without being able to specify the outcome in particular circumstances.
"As AI takes over many tasks, judgement is one of the things that human beings have to offer"
He sees all this as meaning that, in an age of AI, judgement will be an increasing part of what human beings provide. “As AI takes over many tasks, judgement is one of the things that human beings have to offer, so the ability to exercise it becomes even more critical.”
In conclusion, Sir Andrew advises: “Treat judgement as a process, whether you’re making a decision or forming an opinion, particularly when the stakes and/or the risks are high.”
His new book will serve as a guide to the importance of identifying and improving judgement, and not just at work. He suggests it also applies to some big choices in our private lives, such as health and finances.
“Approaching judgements with a sense of structure will not only stack the cards in your favour. It could also be a big relief for those who are concerned that they may not have done all they could in the way they approached a difficult choice,” he adds.
Sir Andrew’s book serves as a reminder, in a world where decisions are often rushed, of the importance of thoughtful, balanced judgement.
