The Expert Advantage: Why Subject-Matter Specialists Are Outperforming Traditional Spokespeople in British Corporate Communications
The Credibility Gap That Training Cannot Close
A pharmaceutical company's communications director handles every media enquiry with textbook precision. Messages are consistent, tone is measured, difficult questions are bridged with practised ease. And yet, when a specialist science correspondent sits down to write her piece, she quotes not the communications director but the company's chief medical officer—a woman who stumbled slightly over her words, asked to clarify one question before answering, and at one point said she needed to check a figure before she could be confident. The resulting article treats the chief medical officer as a credible authority and the company's official statements as background.
This scenario is not unusual. It reflects a shift in how sophisticated audiences—journalists with genuine subject knowledge, institutional investors, parliamentary select committees, sector regulators—evaluate the communications they receive from British businesses. The shift is away from polish and towards substance, and it has significant implications for how organisations approach their public-facing communications.
The traditional model of corporate communications rests on the assumption that a well-trained spokesperson, armed with approved messages and equipped with media skills, represents the optimal channel for an organisation's public voice. It is a model that made considerable sense in a media environment characterised by generalist journalists, short broadcast windows, and limited audience capacity for technical detail. That environment has changed substantially, and the model has not always kept pace.
Why Audiences Have Become More Demanding
Several converging forces have raised the premium on genuine expertise in corporate communications.
The first is the growing specialisation of the media landscape. Many of the journalists who cover complex sectors—pharmaceuticals, financial services, energy transition, artificial intelligence, construction safety—now have deep subject knowledge. They have covered their beat for years, they understand the technical literature, and they are well-positioned to identify when a spokesperson is deflecting rather than engaging. A communications professional who bridges away from a technical question may satisfy a generalist, but will alert a specialist immediately. The specialist will then seek their answer elsewhere, often from a source less sympathetic to the organisation's preferred narrative.
The second force is the expansion of regulatory and parliamentary scrutiny. Select committee hearings, regulatory consultations, and public inquiries have all become more prominent features of the British corporate landscape. These forums are not designed to receive polished messaging. They are designed to establish facts, and the people operating them are specifically trained to distinguish between an answer and an evasion. The organisations that perform best in these environments are invariably those that send people who actually know the subject, rather than people who are skilled at talking about it.
The third force is the rise of investor and analyst engagement that goes well beyond the traditional results presentation. Sophisticated institutional investors increasingly want direct access to the technical and operational minds within organisations they hold or are considering holding. The fund manager who can speak directly to a company's chief technology officer about its cybersecurity architecture, or to its head of regulatory affairs about a pending approval, is extracting information that no communications professional can provide. Organisations that facilitate this access—and prepare their technical experts to engage credibly in it—are building a relationship with the investment community that polished investor relations alone cannot replicate.
The Authenticity Dividend
Beyond the structural changes in audience sophistication, there is something more fundamental at work. Audiences across almost every context have grown more attuned to the difference between genuine engagement and performed communication. The cues are subtle but consistent: the expert who pauses before answering, who volunteers a qualification, who says 'that's a genuinely difficult question' before working through their reasoning, signals something that the media-trained spokesperson almost never can—that the answer they are giving is the answer they actually believe.
This authenticity dividend is particularly valuable in contexts where trust is the primary currency. A chief scientist explaining a product's safety profile with evident personal investment in getting it right is more persuasive than a spokesperson reading from a brief, even if the information conveyed is identical. A chief economist discussing market conditions with the intellectual honesty to acknowledge uncertainty is more credible to a financial journalist than one who delivers only confident projections.
The irony is that many organisations actively train this quality out of their technical experts before deploying them publicly. Media training programmes that focus on message discipline, bridging techniques, and the avoidance of 'difficult' territory can inadvertently strip away precisely the characteristics that make subject-matter experts valuable as communicators. The result is a technical expert who has been taught to behave like a spokesperson—and who is therefore less effective than either.
Preparing Experts Without Diminishing Them
The solution is not to abandon preparation. Deploying a technical expert into a complex media or stakeholder engagement without support is a different kind of error, and one that carries its own risks. The goal is preparation that enhances without homogenising—that equips the expert to communicate effectively without eroding the authenticity and credibility that make them worth deploying in the first place.
Effective preparation for subject-matter experts begins with a clear understanding of the audience and context. A regulatory consultation requires different communication skills from a broadcast interview; a parliamentary committee hearing is a different environment from an investor roadshow. The expert who understands these differences, and has thought through how their expertise maps onto the specific questions and expectations of each context, is significantly better positioned than one who has received only generic media training.
Preparation should also address the specific vulnerabilities that technical experts frequently encounter in public-facing communication. These include the tendency to over-qualify—to hedge so extensively that the core message is lost—and the reverse tendency to assume shared technical knowledge in audiences that do not possess it. Helping experts calibrate their communication for different levels of audience expertise, without condescending to those with less knowledge or oversimplifying for those with more, is a genuine skill that repays investment.
Crucially, preparation should include explicit permission—and encouragement—to say what experts actually think. The subject-matter expert who has been briefed to stay on message will often retreat to that message when challenged, losing the very authenticity that justified deploying them. The one who understands that honest engagement, including the honest acknowledgement of complexity and uncertainty, is more credible than performed confidence will engage far more effectively.
Identifying the Right Experts for the Right Contexts
Not every technical expert is suited to every public-facing communications role, and part of the communications professional's task is identifying who should speak, where, and when. Some subject-matter experts have a natural facility for public communication that requires only light development. Others have the expertise but not the temperament for high-pressure or adversarial environments. The assessment of which experts to develop for which contexts should be as careful as the assessment of what to communicate.
Organisations that do this well maintain a portfolio of credible expert voices—people at different levels of seniority, with different areas of expertise, who have been developed for different communications contexts. The chief executive who speaks to strategic direction, the technical director who addresses operational questions, the scientific adviser who engages with the specialist media—each plays a distinct and complementary role, and the organisation that has developed all three is communicating with a depth and credibility that no single spokesperson, however skilled, can match.
This is, ultimately, a strategic communications question as much as a media relations one. The organisations that are winning the credibility competition in British corporate communications are those that have understood that their most persuasive voices are not always their most polished ones—and have built the infrastructure to deploy them accordingly.
