One of my favorite popular science books is Jared Diamond’s Guns, Germs and Steel. Some didn’t appreciate it as much yet it does a fantastic job of asking big questions. These are the questions most worth asking. The Importance Of Geography Guns, Germs, and Steel is packed with fascinating details, has a great tempo, and…

Good And Bad Profits
Fred Reichheld is best known for his (over) exuberant advocacy of the Net Promoter Score. Introducing Net Promoter he suggests a difference between good and bad profits; an interesting, though theoretically imprecise, idea. Are All Dollars In The Same? Short of outright fraud, isn’t one dollar of earnings as good as another? Certainly, accountants can’t…
Marketing State Of Mind
Marketers often brag about understanding external customers. They often do this while ignoring internal customers. To be a great marketer understanding the end consumer isn’t enough. Having a “marketing state of mind” means trying to solve the problems of your internal customers. Why is that? Internal Customers Of Marketers Imagine a simplified firm: the accountants…
Regression to the Mean
Daniel Kahneman likes to explain an epiphany he had teaching decision-making. (The story is so good you realize you’ll never come up with as perfect an illustration, but then comparing yourself to a Nobel prize winner is never good for the ego). Kahneman was instructing the Israeli Air Force. He announced that rewarding good performance…
Understanding Numbers

Numbers Allow You To Understand Magnitude When I managed the finances of a political party the BBC’s political editor explained on TV that donations totaling 6 million pounds would run my…
Inequality And Efficiency
What do we know about inequality and efficiency? Inequality And Efficiency Is there an equality-efficiency trade-off? Is greater inequality just the price we pay for more efficiency? Economic theory has proven, one hears, that any but cosmetic modifications of capitalism in the direction of equality and democratic control will exact a heavy toll of reduced…
Measuring Competition 2: The Bendle Panda Index
The Herfindahl Index covered in the prior post is an excellent way of measuring competition. Sadly it involves squaring market shares. This seems too much math so in the spirit of simple metrics I’m suggesting a new measure of competitiveness; the BPI or The Bendle Panda Index. It makes Net Promoter look complex and Gigerenzer…
Measuring Competiton 1 The Herfindahl Index
The competitiveness of any industry matters. One way to measure competitiveness is the Herfindahl Index, also known as the Herfindahl-Hirschman Index. Competition Changes Market Outcomes Consumers usually get a bad deal in “concentrated” markets. This is because markets with fewer significant players usually mean less competition. This matters to managers too. If you are considering entering…
A Reason To Be Cheerful
This post from 2013 is a hopeful one about declining overt bias found in polling. While we have had reasons to worry in the intervening years I still stand by the idea that declining overt bias is a good thing. We may not be perfect. I think this is pretty obvious to all, but, at…
Nostalgia
Nostalgia is a major problem for human beings. No, things weren’t better when you were a kid. You just didn’t notice the problems. The Better Angels of Our Nature If the past is a foreign country, it is a shockingly violent one. It is easy to forget just how dangerous life used to be, how deeply brutality…
