Mortality Trends

We read mostly bad news in the newspapers today. Here is a really gratifying chart from The Economist about mortality trends and their decline over the past 40 years.


The decline in mortality is greatest in low income countries, and the gap in mortality between low income and high income countries has shrunk. Yet there's still an obvious gap to be closed there.

It's been shown that high mortality rates, particular among children, lead to high birth rates, so this decline in mortality would seem set to contribute to a plateauing of human population growth.

Data for Insight

Big Data. It's the newest Big Thing in business. Delve into your company's massive database of consumer actions and extract valuable insights - insights that can influence future shopping behaviour.

Aiden and Michel, the authors of Uncharted, turn to a different dataset, Google's database of 30 million digitized books (about one quarter of all books ever published), and a different kind of analysis they call culturomics.

They examine patterns of word usage over the history of all these books to shed light on word origins and usages, politics, history and culture. Actually,  to be perfectly accurate, they examine Ngrams, which are sequences of characters that could be words, phrases, or numbers or whatever. Then they plot the frequency of those Ngrams over time across all books in the database.

This is a simply incredible database to explore. Of course, it doesn't capture all culture shifts, because the dataset does not include any publications except books, and, of course, it totally misses the increasing dissemination of information through video. Nevertheless, it's a pretty powerful lens on history.

Obviously, the dataset is a treasure trove of insights  for the linguist. Consider the graph for chortle, galumphing and frumious,  three words introduced by Lewis Carroll in Jabberwocky, published in 1871.



But such analysis yields insights way beyond mere linguistics. Uncharted discusses who gets famous and the idea of the half life of fame. One chapter explores the revealing disappearance of artists' names during a period when they were politically suppressed, either by the Nazis or the Hollywood black list. The Ngram viewer confirms and provides evidence of the suppression, sort of history as demonstrated by a quant!

The Ngram viewer tool used by Aiden and Michel is available to anyone at Google's Ngram viewer and here are just a few of the charts from the book and others that caught my fancy. (Be careful, this site can be addictive!)

Consider the trend in our environmental thinking, as our terminology shifted from greenhouse effect, to global warming, to climate change.

The Ngram viewer makes clear our shift from tea to coffee.



If you didn't already know it, Ngrams would demonstrate the collapse of Detroit's hegemony in the automobile business.


And what do you think of this chart?

There's been a lot of controversy over Google's book digitization project - impassioned arguments about copyright issues, versus the value of such a database. This application skirts the issue of copyright by restricting itself to meta-analysis of the books.

Have fun playing with the Ngram viewer yourself. By the way, the response time for doing a search like the one above "Plot me the frequency of the words men and women in 30 million books published since 1800" is truly amazing when you think about it. We take Google's extraordinary search capability for granted sometimes, but this just highlights the powerhouse in those Googleplexes.

Jab, Jab, Jab, RIght Hook

Give value before you ask. That's the advice of fast-talking social media expert Gary Vaynerchuk, author of Jab, Jab, Jab, Right Hook. Vaynerchuk was a speaker this week at Rotman and he was energetic and frenetic. He was promoting his new book, which he described as being full of specific strategic and tactical advice for succeeding in social media, wrapped around about a hundred case studies.

In a world saturated with content across all manner of media, you have to work hard to get attention. And you do that by providing people with value. Provide that value and build a relationship before you seek a transaction: to buy your product or to make a donation. In other words, Jab by providing content before you put out the Hook.

Don't use social media sites like Facebook primarily to attract people to your web site: build your relationship there, where people already are. For instance, don't start your own hashtag; jump onto an existing one. Get used to the idea that you don't own your content: once you release it, whether it's in an ad or a YouTube video, it belongs to the world.

Vaynerchuk is very excited - and, believe me, his excitement is very transparent! - about the ability to target very specific segments on Facebook. TV segmentation is about 27% accurate, whereas Facebook segmentation is about 92% accurate. He recommends going for depth, not breadth. Wouldn't you rather connect with 1,000 people highly likely to buy your product rather than 100,000 who aren't at all interested? Use Facebook dark posts to target these people; through them you can get your message out subtly without putting something right on your Facebook page*.

Vaynerchuk's strongest recommendation was this: Become a media company. Provide valuable content to build a relationship, and then slip in your message among the rest of the media. Frankly, I found this advice disingenuous: if every organization becomes a media company, the content market will become even more saturated. Only the early birds are going to catch this worm!!!

The format of this session was mostly Q&A, which worked quite well despite the fact that Vaynerchuk was participating through two-way video. His most common advice to the people with tactical questions was 'become a media company'.

* I definitely have to do more research to fully understand these dark posts. Vaynerchuk's talk was liberally sprinkled with acronyms and was clearly aimed at people who already knew a lot about social media.

112 Weddings


Very good


Doug Block is a documentary filmmaker who supports his documentary 'habit' with a side business filming weddings - 112 of them to be exact over the past 20 years. Block revisits a handful of couples to interview them about their marriages, and how those marriages stack up against their expectations on wedding day. At the same time, he delves into the expectations of a couple preparing for an upcoming wedding.


The ten couples share their ever-after stories, what happened after the wedding. There's a wide range of outcomes - happiness, divorce, stress of children, even one couple who officially marries after years after the life partnership ceremony originally filmed. The short clips are short, varied and oh so revealing. That was the charm for me, seeing into a broad range of marriages, and into the characters of the people involved.

Best lines of the movie: A rabbi says that weddings are usually very happy days, not surprising given the amount of money and liquor being splashed around. He continues that of course the application of liquor and money during the marriage leads to great unhappiness.
