Public Speaking Pointers


 

 

 

 

 

 

 

 

 

 

One common type of advice for speakers is to give them pointers on what to do. The other type of advice to discuss mistakes, and how to avoid them.

 


 

 

 

 

 

 

 

 

 

 

 

 

 

 

There is a long, excellent article by Paul N. Edwards from October 2014 titled How to Give an Academic Talk, v5.2. It is a 14-page pdf which descended from a 5-page pdf article from 2001 titled How to Give an Academic Talk: Changing the Culture of Public Speaking in the Humanities. He has a table with worse or better rules of thumb, as shown above. There also are six gray boxes with advice on:

 

Preparing Your Talk

About Vocal Technique

About Presentation Software

About Timing

Handling Questions

Murphy’s Law applies directly to you:

  plan for disaster

 

And there is a 7-page pdf article by Christine Blome, Hanno Sondermann, and Matthias Augustin in the GMS Journal for Medical Education on February 15, 2017 titled Accepted standards on how to give a Medical Research Presentation: a systematic review of expert opinion papers. They analyzed 91 articles! Their thirty recommendations and their percentages (shown in their Table 1 and greater than 20%) are to:

 

 1] Keep your slides simple - 62.6%

 2] Know your audience - 52.7%

What’s an eggcorn?


 

 

 

 

 

 

 

 

 

 

 

 

The Oxford English Dictionary say that an eggcorn, which first appeared in 2003, is:

 

“An alteration of a word or phrase through the mishearing or reinterpretation of one or more of its elements as a similar-sounding word.”

 

And the Wikipedia page for it says that:

 

“An eggcorn is the alteration of a word or phrase through the mishearing or reinterpretation of one or more of its elements, creating a new phrase that is plausible when used in the same context. Thus an eggcorn is an unexpectedly fitting or creative malapropism.” 

 

There is an article by Merrill Perlman at the Columbia Journalism Review on December 11, 2019 titled ‘Eggcorns,’ and other incorrect homophones. He noted that the eggcorn ‘another thing coming’ had replaced the original ‘another think coming, and the eggcorn ‘hone in’ replaced ‘home in.’

 


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Another article at The Drum on November 20, 2025 is titled This clever Specsavers campaign tackled hearing loss stigma. They came up with a 7-page pdf article titled The Misheard Manifesto, which has the ten eggcorns shown above in a table.

 

My eggcorn was assembled from an egg and corn at OpenclipArt. I also got an acorn from there.

Displaying risks from vaccines and other dangers


 

 

 

 

 

 

 

 

 

 

 

 

There is an interesting article from Edzard Ernst on July 16, 2025 titled Yes, vaccination risks are real – but how do they compare with other dangers? In order to show the range from the tiny one in a hundred million for the MMR vaccine to one in 1,100 for drowning (and up to one) we need to use a chart with a logarithmic scale - as is shown above. I had discussed risk in a post on November 12, 2024 titled I am not going to throw out my black plastic spatulas.

 

Also, back on January 13, 2010 I had blogged about How thin is “extremely thin”? and used a table with a powers of ten for comparing thicknesses over a range in centimeters from one to one in ten to the minus eighth power.

8 presentation mistakes: how to avoid them and fix them

 

 

 

 

 

 

 

 

 

 

 

  

 

 

 

 

 

 

There is a useful post by Naba Ahmed at the Prezi Blog on October 15, 2025 mistitled 8 presentation mistake: how to avoid them and fix them. Those mistakes are:

 

1]  Don’t read directly from your slides.

2]  Avoid overwhelming slides with text.

3]  Create a clear visual flow.

4]  Give your presentation a solid structure.

5]  Pace your speaking.

6]  Use confident body language.

7]  Learn to read audience cues.

8]  Don’t underprepare.

 

Regarding her first point, back on June 10, 2015 I blogged about Don’t annoy us by reading your PowerPoint slides.

 

The article also has advice on How to design slides that connect:

 

Guide the eye with visual hierarchy.

Use color and contrast with purpose.

Choose your fonts wisely.

Select powerful, relevant images.

Balance your visuals and text.

 

I blogged about balancing visuals and text in a post on February 19, 2014 titled Assertion-Evidence PowerPoint slides are a visual alternative to bullet point lists.

 

And the article has sections on how to Master Audience Engagement and to Perfect Your Delivery.

The Idaho Freedom Foundation made a thoughtless proposal to completely eliminate the Idaho Commission for Libraries


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

There is an article by Brett Farruggia at the Idaho Freedom Foundation on November 21, 2025 titled Ending Bureaucratic Excess in Idaho. It also was posted on November 22, 2025 at the Gem State Patriot News blog. It has a totally  thoughtless proposal – to completely eliminate the Idaho Commission for Libraries:

 

“Further savings can come from eliminating unconstitutional agencies that promote DEI ideology such as the Hispanic Commission ($557,283) and the Library Commission ($6,947,300).”

 

Back on September 1, 2025 the Idaho Freedom Foundation had an article titled Public Recommendations to Idaho’s DOGE Task Force to Increase Government Efficiency which listed the Idaho Commission for Libraries at #5 under recommended Agency Eliminations, but left off the DEI claim.

 

The Idaho Commission for Libraries is responsible for Libraries Linking Idaho (LiLI) which has databases with magazines and newspapers for public libraries in the state. It’s our public utility for information - a critical set of research tools for keeping the public informed. Back on February 23, 2020 I blogged about Finding speech topics and doing research. LiLI databases include, among others these 26 from EBSCOhost:

 

Academic Search Premier

Business Source Premier

Computer Source

Consumer Health Complete

ERIC – Educational Resource Information Center

GreenFILE

Health Source: Consumer Edition

Health Source: Nursing/Academic Edition

History Reference Source

Legal Collection

Literary Reference Source

MAS Ultra (for high school students)

MasterFILE Premier

MEDLINE

Middle Search Plus (for middle school students)

Military and Government Collection

Newspaper Source Plus

Primary Search (for elementary school students)

Professional Development Collection

Psychology and Behavioral Sciences Collection

Publication Finder

Religion and Philosophy Collection

Small Business Source

Teacher Reference Center

TOPICsearch

Vocational and Career Collection

 

Based on a state population of 2,032,120 that expenditure ($6,947,300) is only $3.42 per person – and a tiny part of the overall budget for Idaho.

 

Mr. Farruggia has the combination of arrogance and incompetence I have come to expect from the Idaho Freedom Foundation. I suspect he does not know much about what vital services the Commission for Libraries provides.

If you only have a hammer, then everything looks like a nail


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The Savage Chickens cartoon for November 18, 2025 by Doug Savage is titled The Amazing Hammer and is shown above. It illustrates a proverb Wikipedia terms the Law of the instrument. Some web sites attribute versions of it to Mark Twain:

 

Goodreads - “To a man with a hammer, everything looks like a nail”

 

AZ Quotes“If your only tool is a hammer, everything starts to look like a nail.”

 

Quotefancy - “To someone with a hammer, everything looks like a nail.”

 

At Quote Investigator on May 8, 2014 Garson O’Toole discussed it in an article titled Quote Origin: If Your Only Tool Is A Hammer Then Every Problem Looks Like a Nail. He found no evidence for Mark Twain, and rather found a 1962 version by Abraham Kaplan:

 

“Give a boy a hammer and everything he meets has to be pounded.”

 

There also are a 1964 version by Abraham Maslow:

 

“Give a small boy a hammer, and he will find that everything he encounters needs pounding.”

 

and another 1966 version:

 

“I suppose it is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail.”

 

Update November 23, 2025

 

Adam Savage’s 2019 memoir Every Tool’s a Hammer: Life is what you make it discusses the converse. In Chapter 12 Hammers, Blades, and Scissors, on pages 266 and 267 he writes about his friend, Mark Buck:

 

“He was a man with an aversion for fools and a love of tools. If he walked by your workbench and he saw you looking too long for something in your toolbox, he’d instruct you in an almost solemn tone, like a sifu, ‘Remember, in every tool, there is a hammer.’ What he meant was that every tool can be used for a purpose for which it wasn’t intended, including the most basic of operations, like hammering. He also meant that until you learn to see what tools can do beyond their stated purpose, you can’t quite be a maker. Truer words have rarely been spoken.”

What if a commencement speech told you to assume the worst?


 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

  

 

 

 

 

 

 

 

There is a brief and humorous book from 2018 by Carl Hiassen titled Assume the Worst: The graduation speech you’ll never hear. Amazon has sample of first eight pages. It’s just 64 double-spaced pages, with hilarious cartoon illustrations by Roz Chast. Here’s a paraphrase from it:

 

 “This commencement address will never be given, because graduation speakers are supposed to offer encouragement and inspiration.

 

That’s not what you need. You need a warning.

 

After an uncommonly long career observing and writing about misbehavior, I have one piece of advice as you launch yourself from college: assume the worst.

 

Based on the last six thousand years of human history, it’s the only sensible way to proceed. Lowering your expectations will inoculate you against serial disappointments. It will also set you up for heart-lifting surprises on those occasions when someone you meet turns out to be unexpectedly honorable, generous and selfless.

 

…. 1. Live each day as if it’s your last.

      As wise and appealing as this might sound, it’s actually terrible advice. If you live every day as if it’s your last, you won’t accomplish a damn thing. You’ll soon run out of money, your car will get repossessed, you’ll be evicted from your apartment, and the person you’re living with will dump you for somebody with a mid-level management job at BrandsMart.

 

…. 2. If you set your mind to it, you can be anything you want to be.

     Total bullshit. Nobody can be absolutely anything they want to be – no matter how hard they wish, pray or try. I wanted to play major-league baseball like Willie Mays but unfortunately, I couldn’t run, catch or hit like Willie Mays. And I tried. Really hard. By eighth grade I’d bagged the whole fantasy and moved on.

 

…. 3. Try to find goodness in everyone you meet.

     Another waste of time. Relationships aren’t supposed to be reclamation projects. The humane qualities of any new acquaintance should be evident in the first five minutes of conversation – ten minutes, tops.

 

…. 4. Don’t be quick to judge others.

     Are you kidding? If you don’t learn how to judge others – and judge fast – you’ll get metaphorically trampled from now until the day you die.

 

…. To sum up.

     Figure out what you’re good at, and get better at it. Along the way, don’t waste your time on people whose decency isn’t apparent when you first meet for a cup of coffee. Be an astute judge of character, and learn to judge quickly.

 

Read the news. Pay attention. Always aspire to act in a way that cancels out someone else’s cruel or stupid behavior.

 

Never stop worrying. Live each day as if your rent is due tomorrow.

 

And always, always be the one who sleeps near the campfire – the one who would make Darwin proud.”
