Truth in Presentations: Why “Alternative Facts” Destroy Credibility

Why is lying in business presentations so dangerous?

While it seems obvious we shouldn’t lie, the political world has normalized terms like “alternative facts” (Kellyanne Conway) and “truthful hyperbole” (Donald Trump). But in business, exaggerations or half-truths erode trust immediately.

How does today’s environment affect audience trust?

  • We are bombarded daily with fake emails, scams, and misinformation.

  • Audiences have become battle-hardened sceptics.

  • Any exaggeration by a presenter triggers doubt in everything else they say.

What happens if presenters exaggerate?

  • The audience doubts not just that point, but every subsequent word.

  • They may warn colleagues and peers to avoid us.

  • Our professional reputation can be permanently damaged.

How can we maintain credibility as presenters?

  1. Back up every claim with proof. Use verifiable data, references, case studies, and testimonials.

  2. Include sources on slides. Even if 99% won’t check, assume they will.

  3. Separate facts from opinions. Clearly signal when something is your personal view.

  4. Keep data fresh. Outdated statistics undermine credibility.

  5. Distribute supporting documents if needed, to reinforce reliability.

What’s the golden rule for presenters?

👉 “If in doubt, leave it out.”
Anything unverifiable, outdated, or exaggerated will damage your credibility more than it helps.

Summary & Key Points:

  • Never use exaggeration, “truthful hyperbole,” or “alternative facts.”
