Happy Friday! Here are eight cool things I read this week. 


Rob Bennett writes a great piece about rethinking investing beliefs:

Academic Researchers in This Field No Longer Have Confidence in Their Work. Rob Arnott once spoke at a conference of academic researchers in this field and asked how many still believed in the Efficient Market Theory. A tiny number of hands went up. He then asked a follow-up question: How many of the researchers would be using the Efficient Market Theory as the core assumption in the research that they would be doing when they got back to the office on Monday morning? Nearly every hand in the room shot up. Huh?


America now has more prisons than colleges:

We have slightly more jails and prisons in the U.S. -- 5,000 plus -- than we do degree-granting colleges and universities. In many parts of America, particularly the South, there are more people living in prisons than on college campuses. Cumberland County, Pa. -- population 235,000 -- is home to 41 correctional facilities and 7 colleges. Prisons outnumber colleges 15-to-1 in Lexington County, S.C.


WD-40 (NASDAQ:WDFC) -- a company that makes spray metal lubricants -- has an interesting way of describing itself:


As countries get richer, the share of labor devoted to agriculture plunges


ESPN is one of the only major cable networks whose traffic didn't decline in the last year


Oil is now cheaper than water (this article is a few weeks old; oil is even cheaper now): 

Brent crude was trading just below $60 a barrel on Tuesday morning, meaning that it now costs about 24 pence a litre. An oil barrel is 159 litres and currently the British Pound is 64 pence to the dollar.

As Reuters' John Kemp tweeted this morning, that is about 40% cheaper than a bottle of Evian mineral water in British supermarkets, where a six-pack of 1.5 litre bottles sells for £3.80.


Illinois is taking drastic steps to help people retire:

Illinois is taking a novel approach to getting its residents to save for retirement. Starting in 2017, most state residents with jobs who don't already have a retirement plan at work will be automatically enrolled in individual retirement accounts, funded through a 3 percent deduction from their paychecks.
