In part two of a series exploring the skills driving excellence in legal practice, which AI cannot replicate, Michaela Hardwick turns to influence literacy. How do the six universal principles of influence apply to practice at the Bar?
Think of the last professional decision that felt more certain than the evidence actually warranted. Not the case where you were right and knew why. The one where the certainty arrived first and the reasons followed; where you were more persuaded than informed. What was the persuading factor?
The first article in this series reasoned that professional judgement rests on self-awareness, knowing your own patterns before they make decisions for you (‘The human barrister (1) – Your judgement advantage’, Counsel, September 2026). This second article shifts that focus outward. Self-awareness tells you how your mind tends to move; influence literacy tells you what moves it, and what you are moving in others when you advocate, negotiate or advise. A barrister who understands one but not the other is only half informed.
The question at the top is uncomfortable, because the honest answer is rarely ‘the facts’. More often it is one of a small set of psychological triggers that operate on all of us, lawyers included, below the level of conscious notice. Dr Robert Cialdini set out six of them in his New York Times bestseller Influence: The Psychology of Persuasion (HarperBus: 2007). A seventh, unity, was added later; the original six remain the reference point in the field and are the six this article uses. Every one of them is legitimate. Every one of these so-called ‘weapons’ is exploitable; on you as much as by you.
The Bar Standards Board’s (BSB’s) Professional Statement for Barristers puts this plainly. Competence 2.1 requires barristers to act with the utmost integrity and independence at all times, and specifically to recognise the explicit and implicit pressures to behave otherwise, resisting them even against personal interest. Influence literacy, in other words, is not a soft add-on to advocacy skill. It is what competence 2.1 is asking all practising barristers to do.
Reciprocity is the pull to return what we have been given, a favour, a concession, a kindness, before we decide to repay it. At the Bar it is easiest to see in the relationship between a barrister and their clerk. A clerk who has fought hard for a good fee, or found space in an impossible diary, has given you something real, and the pull to reciprocate, to take the next brief you would rather decline, or to hold a rate you should renegotiate, is genuine and rarely examined. Recognising the obligation does not mean refusing it. It means noticing when the relationship, not the brief, is making the decision.
Commitment and consistency is the drive to act in line with choices already made, so a small first step makes a related second step feel obligatory. An early position, taken in conference or a skeleton argument, creates its own momentum. Once stated, a view becomes harder to revise, not because the evidence has stopped moving, but because consistency with your earlier self starts to feel like a professional obligation in its own right. Client anchoring works the same way in reverse: a client’s early, confident framing of their case can quietly become yours. It can also entrench the client. The longer a position has been held, the harder it becomes to hear anything that complicates it, often why a conference stalls.
Social proof is the tendency to look to others, particularly people like us, for the correct way to act when uncertain, assuming that what many people do must be right. ‘What most barristers would do’ is a powerful heuristic and a genuinely unreliable one. It has a newer variant, the professional success visible on LinkedIn and elsewhere, curated rather than representative. A feed full of wins tells you what people choose to post, not the base rate of wins. Treating visible success as evidence of typical success is social proof doing exactly what it is designed to do.
Authority as a ‘weapon of influence’ is the tendency to defer to those who appear to hold expertise or legitimate power, without testing whether the deference is warranted. Deference to silk, to the bench, and to ‘what the AI recommended’ all draw on it, and the AI variant is newest and least examined. A confident, fluent AI output carries none of the earned authority of a senior colleague’s judgement, yet it can produce the same reflexive deference. Judicial authority is its own case again. Reading the room correctly is advocacy; treating a judge’s evident view as settling the legal question before argument has finished is something else.
Liking is our tendency to say yes more readily to people we like, and to people who appear to like us in return. It is where the risk is least visible, because warmth toward a client is not a flaw. It is often the relationship working as it should. The BSB’s own disciplinary record offers a stark illustration of what happens when that warmth, or the loyalty it produces, goes unchecked. In April 2026 a disciplinary tribunal disbarred a barrister, called in 2005, after she admitted three charges of professional misconduct arising from a Family Court hearing in June 2024. In conference on 5 June that year, her client told her a child, subject to a court order, had already been moved to a new nursery in breach of it. At a hearing a fortnight later, she advanced an application that gave the impression the move had not yet happened, and did not correct that impression for the court. The BSB’s published finding records the breach as engaging Core Duty 1, the duty to the court, and Core Duty 2, the duty to act in the client’s best interests; she was ordered to pay costs of £3,210, and the finding remains subject to appeal. Nothing in that finding turns on Cialdini’s terms, but the shape of it; a barrister drawn incrementally toward protecting her client’s position rather than correcting the court, is the risk liking presents in smaller, more survivable form, to every practitioner who likes their client.
Scarcity is the pull of things that appear rare or about to disappear, valued more highly for that reason alone. Genuine deadline pressure is real and worth respecting. Manufactured urgency, the ‘I need this by end of day’ that turns out not to have been true, is a different thing wearing the same clothes, and the two are worth telling apart.
AI adds a new authority heuristic to all of this: confident, fluent, and entirely capable of being wrong. A lawyer who defers to a persuasive output without interrogating it is not exercising judgement. They are being influenced by it, exactly as Cialdini described. The obligation under Core Duties 1 and 4 to exercise independent judgement does not pause because the source of the pressure is a machine rather than a person.
Recognising these six principles will not make you immune to them; nobody is. What it gives you is the ability to notice, in the moment, when a decision is shaped by something other than the merits, and to ask whether that is the decision you would make anyway. That pause is where independent judgement lives.
