The 7 Deadly Sins of Public Speaking


Some speaking sins, like the occasional “ah” or “um”, will not doom your presentation. With good content, you can earn forgiveness from the audience for those sins.

Other speaking sins are so grave that when you commit them, your speech or presentation is certain to fail. This article reveals the seven deadly sins of public speaking.

7 Deadly Sins of Public Speaking

Deadly Sin #1: Sloth

Sloth, or laziness, is committed by speakers who fail to prepare.

Speaking in public, whether formally or informally, is an essential activity that requires effort. Yet, the majority of people expend no effort to improve their effectiveness as a speaker. Tragically, they are content to drift from one frustrating presentation to the next.

Speaking in public, whether formally or informally, is an essential activity that requires effort.

You can avoid sloth in a number of ways:

  • Enroll in a public speaking course
  • Read public speaking books
  • Read public speaking blogs
  • Join Toastmasters or another local speaking club
  • Study great speakers
  • Hire a speaking coach

(By reading this article, you’re making the effort to improve. Sloth has no claim on you!)

Failing to prepare for life by improving your speaking skills leads to a chain of excuses, characterized by…

Deadly Sin #2: Envy

Envy is characterized by a false belief that great speakers are simply lucky to have been born with natural speaking skills.

You’ve heard the excuses from your colleagues, haven’t you?

  • “She’s so lucky! She’s a natural speaker!”
  • “Hmph! It’s so easy for him to speak in front of people.”
  • “No, I couldn’t deliver the proposal. I’m not a speaker.”

People who are envious of the “natural” skills of others are more likely to apply misguided solutions when confronted by an unavoidable speaking situation:

  • They steal stories and anecdotes from others rather than creating original ones
  • They copy PowerPoint slides from others even if they don’t quite apply
  • They mimic the oratorical style of others and lack authenticity

Because of bad habits like this, speakers suffer from lack of confidence. They know the stories, the slides, and the words are not their own. Nervousness results because they fear being exposed, and this nervousness leads to crazy behaviors like…

Deadly Sin #3: Lust

Please don’t picture the audience naked, especially if I am in your audience.

The lustful speaker attempts to calm their nerves by applying the common (yet terrible) advice to picture the audience naked!

Please don’t picture the audience naked, especially if I am in your audience.

In theory, picturing your audience naked makes them seem as vulnerable as you feel. It may provide a brief lighthearted moment to feed your teenaged appetite, but it won’t help you speak better.

More likely, it will cause an additional distraction and impede your efforts to connect with your audience. Consider this: how easy is it for you to communicate something meaningful to a room full of naked people? Can you inspire them? Impossible.

Nervous speakers who avoid this lustful deadly sin are, unfortunately, still prone to committing another deadly sin…

Deadly Sin #4: Gluttony

Gluttony is exhibited by speakers who believe that more is always better.

More slides, more bullets, more examples, more facts, more numbers, more details, more words — more of everything.

Packing all possible material into your presentation and then speeding through it is flawed, despite your best intentions to provide maximum value. More is (usually) not better. Cognitive research shows that people have a limited capacity to absorb information (see Kosslyn’s Clear and to the Point and Mayer’s Multimedia Learning). Overloading that capacity will reduce their ability to absorb anything at all! Quantity is no substitute for quality.

It is better to focus your presentation on your core message, select only the very best support material (facts, slides, anecdotes), and speak at a reasonable pace. Supplementary material, if necessary, belongs in a handout.

All of this gluttony — too many slides, too many stories, too many details — leads the speaker down a dark and dirty path towards…

Deadly Sin #5: Greed

Speaking for more than your allotted time violates the contract you have with your audience, and that’s never a good thing.

Greed is the deadly sin of excess, and is committed by a speaker who goes over time.

Does this sound familiar?

  • “Oh, is that clock correct? I’m only halfway through…”
  • “I haven’t gotten to the good part yet…”
  • “Are there any objections to cutting our lunch break in half so I can finish this?”

Speaking for more than your allotted time violates the contract you have with your audience, and that’s never good. People are busy and do not appreciate having their time wasted. Nobody will complain if you finish a few minutes early.

If you go over time, negative emotions begin to fill the room, making you more susceptible to experience…

Deadly Sin #6: Wrath

Wrath, or uncontrolled anger, is committed by a speaker who handles problems in the worst possible way.

As a speaker, you should always remain in control. No matter how bad your presentation is going, keep calm. Don’t let these frustrations provoke you:

  • When you make a mistake (even a big one), resist the urge to draw more attention to it by cursing yourself in an attempt to draw pity.
  • When an audience member is disrupting the room, resist the urge to “solve” it with sarcasm.
  • When the room or venue logistics fail, don’t start blaming the organizers or anyone else. Instead, roll with in and move on.
  • When an audience member is heckling you, do not take the bait.

Getting angry — whether at yourself, someone in the audience, or some other factor — is one of the worst things you can do. Your audience will feel uncomfortable and your credibility will be diminished considerably.

Finally, the first six speaker sins are all symptoms of the deadliest speaking sin of them all…

Deadly Sin #7: Pride

Pride is committed by a speaker who believes that public speaking is about them.

It’s not.

  • It’s never about you.
  • It’s never about your impressive accolades in your introduction.
  • It’s never about your dazzling delivery where you channel Churchill.
  • It’s never about your sumptuous slides which prominently feature your company logo beside dazzling 3-D pie charts.

Public speaking is always about the audience and the message you want to convey. Failing to put the audience first will kill any presentation. You need to perform audience analysis to discover how best to structure your presentation and deliver the message.

It’s never about you. Public speaking is always about the audience and the message you want to convey.

Avoid this sin by starting to analyze your presentation from the audience’s perspective. Amazingly, most of the other speaking sins will go away.

  • You’ll recognize that you need to prepare. (Sloth)
  • You will realize that you are uniquely capable of delivering your message to this audience. (Envy)
  • You will trim all of the fluff to deliver a message which is focused and easy-to-understand. (Gluttony)
  • You will respect the time your audience has given you. (Greed)
  • You won’t saddle your audience with your problems. (Wrath)

As for Lust when speaking, well… that’s just silly.
