The Graying of America (Or Bad Demography)

I never really liked the classic definition of boomers as those born 1946 to 1964. Its overbroad, and well, wrong. That age cohort should really end in 1959. I see why they Demographers made up that range — its so there is a seamless, artificial flow right into to the Gen X group, born 1965…Read More

A Modest Proposal

@TBPInvictus Now for something completely different. That we have become a numbers (and statistics) obsessed society is beyond debate. I’m not sure when it started (Cosmo mag, maybe?), but it’s gotten out of hand. Websites everywhere tell me the X number of things I need to know about Y. Sports, particularly baseball, have gone totally…Read More

Terry Jeffrey, Hack Extraordinaire (Fun with Numbers Again)

@TBPInvictus here. In yet another stunning display of journalistic malpractice, Terry Jeffrey put out the following piece after last Friday’s NFP release:     Because it suited his (political) purpose, Jeffrey jumped on the Household Survey; looking at the Establishment Survey would not have provided such a dramatic headline. Indeed, it would have provided, for…Read More

Media Hall of Shame: Black Friday Reporting

I am writing up my BBRG coverage of the innumerate business reporting of Black Friday and the holiday shopping weekend. The press as per usual got it wrong again this year. Here is the press release from the  NRF, pushing their usual survey silliness as if it were actual retail sales data: “More than 141…Read More

Enjoy Black Friday But Ignore NRF Surveys

Thanksgiving is but a few days away. We celebrate by the giving of thanks for whatever bounty has come your way. It is a warm and wonderful holiday full of family and tryptophan and good cheer. Black Friday, the day after turkey day, is the official kick off of the season I like to call…Read More

In this final interview shot by filmmaker Erol Morris, Mandelbrot shares his love for mathematics and how it led him to his wondrous discovery of fractals.

The Beauty of Mathematics

“Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” —Bertrand Russell   BEAUTY OF MATHEMATICS from PARACHUTES.TV on Vimeo.

About Our “Spending Problem” (Revisited)

@TBPInvictus here It’s a well established fact that the Obama administration has been spending like a drunken sailor since the day he was inaugurated. I first wrote about his spendthrift ways here, toward the end of 2010 (has it already been three years?). Some time has now passed, so how’s it going? Let’s take another…Read More

What Do Hedge Funds Spend On Regulatory Compliance?

Every now and then, I read an article that is factually accurate, technically correct — and utterly misleading. Items like this are “accurate but false” as they leave the reader with an impression of something that is incorrect. Because the world is nuanced and not black and white, the sum of many facts, statistics and…Read More
