Leadership beliefs vs leadership behaviour: why development starts with what leaders believe

Why feedback alone rarely changes behaviour

Every Head of Talent knows the scene. The 360° report is on the table, the leader nods, recognises themselves, resolves to do better. Six months later the team experiences the same behaviour. That is rarely a lack of insight. It follows from the fact that behaviour is only the end of a chain – and feedback almost always describes only that end.

The research here is sobering. Smither, London and Reilly (2005) meta-analysed 24 longitudinal studies and found that ratings from direct reports, peers and supervisors improve only a little on average after multisource feedback; the authors explicitly caution practitioners not to expect large, widespread improvement. Improvement became more likely when the feedback signalled that change was needed, when leaders had a positive orientation to feedback, saw the need themselves, believed change was feasible, set appropriate goals and took action. Every one of those conditions is a matter of belief, not of information.

What a behaviour-only 360° cannot see by design is set out in What a behaviour-only 360° misses. This essay steps further back, to the assumptions from which behaviour arises.

Beliefs are operating assumptions, not values

DefinitionBelief (leadership belief)

A usually unspoken assumption about how leadership works and what happens if one behaves differently – "if I don't check it myself, it will go wrong", or "conflict costs more than it earns". Unlike values ("quality matters to me"), beliefs are if-then rules that steer everyday decisions without being consciously retrieved. In the LEADBeyond 360° model, Belief is the first layer in the chain Belief → Capability → Trigger → Behavior → Outcome, with Well-being as the cross-cutting energy buffer.

The distinction matters in practice. Values can be professed in a leadership charter without anything changing. Operating assumptions decide at 5:40 pm whether the leader rewrites the client presentation one more time or lets it go out the way the team built it. Without knowing the assumption, all you see is the result: a leader who "can't let go".

Robert Kegan and Lisa Lahey coined the image of an immunity to change for this mechanism: a sincerely held improvement goal is kept in equilibrium by a hidden, competing commitment – and beneath that lies a big assumption the leader has never tested, because it never felt like an assumption, only like reality. As long as the assumption stands, the old behaviour is the rational choice. Which is why mirroring it back achieves so little.

Limiting tendencies were once success strategies

The second reason behavioural feedback bounces off: the patterns that limit a leader today are what got them where they are. The consultant who stood out for uncompromising quality became a manager because he checked every number. The one who navigated gracefully around conflict was promoted because clients liked her. The belief underneath was confirmed for years – with praise, bonus, promotion. It is not an error; it is a formerly correct answer to an earlier role.

That is also why these tendencies intensify under pressure. When a project starts to go wrong, a leader does not reach for what they learned in the last workshop, but for what has rescued them before. LEADBeyond 360° measures seven such limiting tendencies – from perfectionist control through harmony-seeking to decision avoidance – with two Belief and two Behavior items each, so that assumption and observed behaviour sit side by side. What pressure does to leadership is the subject of Leadership under pressure.

A worked example: from a control belief to a passive team

In the report that is a constellation worth more than any single number: the leader's strong agreement with the Belief items behind perfectionist control and micromanagement – both belong to the Over-Control pattern in the model – behaviour that others experience as control, and a self-image that differs from it. How to read such self–other differences is explained in Self–other gaps in leadership.

Why only the leader rates beliefs – and what that means

Supervisors, peers and direct reports can observe what a leader does. What the leader believes, they can only guess. That is why in LEADBeyond 360° only the leader answers the 31 Belief items, while raters assess capability, behaviour and outcomes. Three consequences follow.

• A Belief score is an indicator, not a verdict. A single statement a leader agrees with proves nothing – it is a prompt for a conversation. Meaning emerges only when it is set against the behaviour others observe.
• The leader can be mistaken, but cannot be "wrong". Agreeing with a control assumption is not a failing; it is an honest answer. That is why this layer belongs in development, never in appraisal.
• The comparison is the actual diagnostic. The report sets the Belief self-ratings against observed behaviour and flags where the two diverge – explicitly as a hypothesis, not a finding. Self-efficacy in Bandura's sense – believing one can actually do something – is captured separately as Capability; the gap between knowing and doing is the subject of The gap between capability and behaviour.

How a debrief works with a belief

Working with a belief follows a simple sequence in our debriefs. It never begins by asking the leader to drop the belief – like knocking out a load-bearing wall without knowing what rests on it.

1. Name it without judging it. The consultant reads out the Belief statement the leader agreed with and asks: where do you know this sentence from? In which role was it right?
2. Honour what it earned. What has this assumption made possible for the leader? Only once the gain has been spoken can the price be discussed.
3. Show the price through the raters' eyes. Now the raters' behaviour scores and the free text come in – not as a verdict, but as a description of what the assumption triggers around the leader today.
4. Restate the assumption as a hypothesis. "If I don't check, it goes wrong" becomes "I assume it goes wrong if I don't check". Same sentence, different status.
5. Agree a small, safe experiment. One document, one meeting, one week without the old safeguard – small enough that the leader can risk it, large enough that the assumption gets data.

Why so careful? Because the effect of feedback weakens as soon as it shifts attention from the task to the self – the central proposition of the feedback intervention theory of Kluger and DeNisi (1996), whose meta-analysis found that feedback interventions improve performance on average, but that more than a third of them made it worse. A belief is the most personal thing a 360° touches – which is why it belongs in a facilitated conversation, not in an automated text block.
