The 2026 Edelman Trust Barometer - And What It Means for Cross-Selling in Law Firms

The 2026 Edelman Trust Barometer reinforces a theme that has been building for several years: trust is personal and earned rather than institutional.

Across markets, respondents continue to place greater trust in experts than executives, in “someone like me”, and in demonstrated expertise over brand reputation. Institutions are no longer automatically credible.

For professional services firms, and particularly law firms, this shift has important internal implications.

Trust Is Personal - Even Inside Institutions

Edelman’s findings show that trust concentrates around individuals who demonstrate expertise and reliability. People want proof. They want familiarity. They want to see how someone thinks before they rely on them.

That dynamic mirrors how client relationships function in law firms. Clients may instruct a firm, but they trust a partner. Trust is localised, personal, and hard-earned.

Cross-Selling Is a Trust Transfer

When a partner introduces a colleague to a client, they are not simply expanding scope. They are transferring trust. They are attaching their own reputational capital to someone else’s expertise.

That transfer carries risk:

• Reputational risk: ‘will this colleague reflect well on me?’
• Relationship risk: ‘will this introduction strengthen or destabilise my client relationship?’
• Performance risk: can they deliver at the level my client expects?

In a low trust environment where scrutiny is constant, these risks are real.

Awareness Is the Foundation of Trust

One of the most consistent findings in the Trust Barometer is the premium placed on visible expertise. Trust flows toward people who demonstrate their thinking, articulate their judgement clearly, and show evidence of competence.

The same logic applies internally.

If I do not clearly understand:

• What you actually specialise in,
• How you approach risk,
• How you communicate with clients,
• How you think about complex issues,

…then introducing you to my client feels speculative.

Awareness and trust are not separate barriers to cross-selling. Awareness is the precondition for trust. 

Without familiarity, perceived risk remains high.

And in professional services, where relationships are the product, perceived risk drives behavior.

The Internal Trust Deficit

Law firms often assume that because they operate under one brand, internal trust is implied. But Edelman’s broader findings suggest that institutional affiliation alone no longer guarantees confidence.

Trust is built through exposure and evidence.

Within many firms, lawyers operate in concentrated trust networks:

• Within their practice group,
• Within their office,
• Among colleagues they have worked with before.

Beyond those networks, familiarity drops. And when familiarity drops, perceived risk rises.

This creates a structural friction point for cross-practice collaboration.

Not because lawyers are resistant to growth. But because they are protective of trust.

Risk Sensitivity in a Low-Trust Environment

The 2026 Barometer highlights rising grievance, economic anxiety, and systemic scepticism. In uncertain environments, people become more risk-sensitive. They default to known relationships. They avoid unnecessary exposure.

That psychology applies just as much inside organisations as it does externally.

Introducing a colleague to a client is optional. Protecting a trusted relationship is not.

In volatile or highly scrutinised markets, partners will instinctively prioritise preservation over expansion unless confidence in the colleague is strong.

Cross-selling therefore fails because the perceived trust exposure outweighs the upside.

What This Means for Law Firm Leadership

If we view cross-selling through a trust lens rather than a sales lens, the strategic implications shift. Incentives and compensation structures matter. But they cannot compensate for a trust deficit.

Improving cross-selling requires strengthening the internal architecture of trust:

• Making expertise visible across the firm.
• Creating clarity around who does what, and how they do it.
• Increasing exposure to colleagues’ thinking and judgement.
• Reducing uncertainty around performance quality.

When expertise is there to see, introductions feel sensible rather than risky. When colleagues are familiar, collaboration feels safer. 

A Broader Reflection

The 2026 Edelman Trust Barometer tells us that trust is no longer a passive asset. It must be demonstrated continuously through competence, transparency, and credibility.

For law firms, that insight has both external and internal relevance.

• Externally, clients expect proof of expertise.
• Internally, lawyers require reassurance before extending their own trust.

Cross-selling is not primarily a revenue challenge. It is a trust challenge.

Firms that invest in visibility, clarity, and demonstrated expertise will find collaboration easier - not because they push harder, but because the risk of saying “yes” feels lower. In 2026, growth in professional services is about strengthening the internal conditions under which trust can travel.
