Leadership Principles

What actually makes people follow you — and what destroys trust overnight. Evidence-based, no platitudes.

Updated April 2026

Leadership Is Behaviour, Not Title

You don't become a leader by being promoted. You become a leader when people choose to follow you — when they trust your judgement, feel safe around you, and believe you have their interests at heart. A title gives you authority. Behaviour gives you influence. Authority makes people comply. Influence makes people commit.

Psychological Safety

Google's Project Aristotle studied 180+ teams to find what made the best teams effective. The number one factor wasn't talent, experience, or resources — it was psychological safety: the belief that you won't be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes.

How to Build It

  • Admit your own mistakes first. When the leader says "I got that wrong," it gives everyone else permission to be fallible. If you never show vulnerability, no one else will either.
  • Reward the messenger. When someone brings bad news, thank them. Publicly. If people learn that raising problems leads to blame, they'll stop raising problems — and the problems will get worse in silence.
  • Ask, don't tell. "What do you think?" is the most powerful leadership question. It signals that you value input and that dissent is welcome.
  • Respond to failure with curiosity, not anger. "What happened? What can we learn? What would we do differently?" not "Who's responsible? Why did you let this happen?"
  • Follow through. If someone raises a concern and you do nothing, the message is clear: speaking up is pointless. Act on input, or at minimum explain why you chose a different direction.

The Paradox of Safety and Performance

Psychological safety doesn't mean no accountability. It means accountability plus trust. The highest-performing teams have both high psychological safety AND high performance standards. Safety without standards is comfort. Standards without safety is fear. You need both.

Decision Authority

One of the most common leadership failures is unclear decision authority — nobody knows who's deciding, so either nobody decides (paralysis) or everybody decides (chaos).

The RACI Framework

RoleMeaningKey Rule
ResponsibleDoes the workCan be multiple people
AccountableMakes the final decision, owns the outcomeMust be exactly one person. Never a committee.
ConsultedProvides input before the decisionTheir input is sought but not binding
InformedTold about the decision after it's madeNo input needed, just awareness

Commander's Intent

From military doctrine: communicate the objective and constraints, not step-by-step instructions. "Take that hill by sunset without crossing the river" gives the team enough direction to adapt when things go wrong (they always do) while preserving flexibility.

In business terms: "We need to reduce customer churn by 15% this quarter. Budget is £50K. Method is your call." This is leadership. "Send an email to churned customers on Tuesday with subject line X and body text Y" is micromanagement.

Giving Feedback

Most feedback is either too vague to be useful or too harsh to be heard. Effective feedback is specific, timely, and actionable.

The SBI Framework

  • Situation: "In yesterday's client presentation..."
  • Behaviour: "...you interrupted the client three times while they were explaining their concerns..."
  • Impact: "...which made them visibly frustrated and I think reduced their confidence in us."

No judgement about character ("you're rude"), no vague generalisation ("you need to be more professional"), no sandwiching between false praise. Just: here's what happened, here's the effect, let's discuss.

Receiving Feedback

  • Listen without defending. Your instinct will be to explain, justify, or counter. Resist it. Just listen.
  • Thank the person. Giving honest feedback is uncomfortable. The fact that someone cared enough to tell you the truth is valuable.
  • Separate the signal from the noise. Not all feedback is equally valid. But there's almost always a kernel of truth, even in poorly delivered feedback.
  • Decide what to do with it later. You don't need to accept or reject feedback in the moment. Take it away, sit with it, and then decide.

Leading Under Pressure

How you behave when things go wrong reveals more about your leadership than how you behave when things go right.

  • Stay calm visibly. Your team calibrates their panic to yours. If you're visibly stressed, they'll be more stressed. If you're composed (even if you don't feel it), they'll be calmer.
  • Communicate more, not less. In a crisis, silence breeds anxiety and rumour. Even if you don't have all the answers, communicate what you know, what you don't know, and when you'll know more.
  • Focus on the next action. Not the blame, not the root cause analysis (that comes later), not the existential crisis. What is the single most important thing to do right now?
  • Protect your team from external pressure. Your job in a crisis is to be the buffer between external chaos and your team's ability to focus. Shield them from politics, from executives demanding updates every 5 minutes, from scope creep.
  • Debrief honestly afterward. Once the crisis has passed, conduct a blameless post-mortem. What happened? Why? What do we change? The goal is learning, not punishment.

What Destroys Trust

Trust is built in drops and lost in buckets. The fastest ways to destroy it: taking credit for others' work, blaming your team for your mistakes, saying one thing and doing another, playing favourites, withholding information to maintain power, and being nice to people's faces and harsh behind their backs. One incident of any of these can undo months of trust-building.

The Leadership Compounds

The final insight: leadership compounds. Every good decision you make, every time you handle pressure with grace, every time you give honest feedback with care, every time you admit a mistake — it builds. People notice. Trust accumulates. Reputation grows. Opportunities appear.

And it compounds in the other direction too. Every broken promise, every moment of cowardice, every time you choose politics over truth — it erodes. Slowly at first, then all at once.

Choose the compounding direction wisely.

The One-Line Leadership Test

Would your team voluntarily follow you to a new company? If the answer is yes, you're leading. If the answer is no, you have a title.
