What is it about people who write or speak for a living? You often hear them proudly announce that they can’t do math. Which really means they are admitting they’re not properly educated.
It has consequences. If journalists are innumerate, they can’t do their job well. Anyone with an agenda can easily mislead them, and in…

Dear Albertans
Harry Shannon
I sent the article below to the Calgary Herald as a possible contribution to their Opinion page. I haven’t even had an acknowledgement.
Some context: I wrote this after hearing the Alberta Premier Jason Kenney on the news. Kenney and his government have tried to keep the province’s economy open during the COVID-19 pandemic.…
Emerald is Not a Gem
Harry Shannon
This morning I got an email from Emerald Publishing, publishers of hundreds of academic journals. The email began:
“In August 2020, we commissioned a global survey to gather views on change within the academic sector. The survey was sent to a random selection of 172,033 academics, librarians and students within …
How big a wealth gap is too much?
Harry Shannon
I wrote this letter to Prime Minister Justin Trudeau, and several members of his cabinet:
There is a lot of talk about a wealth tax and about billionaires, but it’s hard for most people to understand just how much money the ultra-wealthy have. Even as a statistician, I have trouble getting to grips with the numbers. So I wan…
Who is most at risk for COVID-19?
Harry Shannon
Data just released show that “Black people and other people of colour make up 83 per cent of reported COVID-19 cases while only making up half of Toronto's population.”
Quick now – how many times more likely are these racialized people to get COVID-19 than the rest of the Toronto population, i.e., white people? 1 ½ ti…
Which do you trust: The numbers or your impressions?
Harry Shannon
I'm a big fan of football/soccer (your choice about what to call it). In particular, Manchester United of the English Premier League. I have supported them ever since I was about six or seven years old, when Gordon, the boy next door who was a year older and therefore knew everything, told me they were the team to go for.
So wh…
Are you a swinger?
Harry Shannon
I was listening to CBC radio this morning. A reporter was talking about the popularity of Ontario Premier Doug Ford, and said that a year ago Ford’s approval rating was -49% [if I remember correctly]. Today, his rating is +39%. The reporter continued, saying that this represented an 88% swing.
This, of course, is wrong. To un…
Models and COVID-19
Harry Shannon
We all want to know how the pandemic will play out. Sorry, I don’t.
But some groups are doing mathematical modelling to try to predict what will happen. The statistician George Box famously noted that all models are wrong but some are useful. His point was that a model is an attempt to describe some aspect of the world in mat…
“We’re Number One” – Trump
Harry Shannon
As the number of deaths from COVID-19 in the U.S. climbed above the total in Italy to become the highest in the world, Donald Trump claimed: ‘Thanks to me, we’re number one.’
In a rambling press conference, Trump said: ‘Several other countries have tried to beat us, but they haven’t succeeded. Countries like Ita…
A post on, you guessed it, coronavirus and COVID-19
Harry Shannon
Some thoughts on the coronavirus and its impact.
I am not paying attention any more to the number of new confirmed cases. That’s because, as far as I can tell, whether someone is tested is rather arbitrary: has the person sought care; does the person have symptoms; how severe are the symptoms; are there enough testing kits; h…
