Markov Chains explained visually
Markov chains, named after Andrey Markov, are mathematical systems that hop from one "state" (a situation or set of values) to another. For example, if you made a Markov chain model of a baby's behavior, you might include "playing," "eating", "sleeping," and "crying" as states, which together with other behaviors could form a 'state space': a list of all possible states. In addition, on top of the state space, a Markov chain tells you the probabilitiy of hopping, or "transitioning," from one state to any other state---e.g., the chance that a baby currently playing will fall asleep in the next five minutes without crying first.

Why statistical discrimination is higher than is either socially optimal or Bayesian rational - Marginal REVOLUTION
But now introduce a further assumption.  There are multiple layers of evaluation, and at each layer people, and institutions, wish to be seen as successful talent spotters, mentors, and coaches.  High schools wish to promote students who will get into good colleges.  Colleges wish to invest in students who will get into best grad schools, or get the best jobs.  Firms wish to hire workers who will rise to CEO, even if elsewhere.  And so on.  Let’s say there are ten levels to this “game.”

Houston Rockets GM Daryl Morey calls LeBron James best ever by a big margin
Houston Rockets general manager Daryl Morey is a stats guru. He says he has checked the numbers and there's no question: LeBron James is the best player in the history of the NBA "by a bit of a big margin."
Talking Wednesday in an appearance on The Dan Patrick Show, Morey said, "You look at his ability to generate wins and championship probability over time, and you basically break that down. You don't need all the numbers. You can watch as well and see that.
"But if you basically isolate that and also look at the career he's had, frankly I think at this point it's become a bit of a big margin, actually, where he's come out ahead. I know that's a little controversial."

Women in Technology | Facts | How to stop women mid-career leaving tech
It didn’t surprise me that women were leaving tech mid-career. Anecdotally, I hear it a lot. But there’s nothing like empirical evidence to bring the message home.  The number of women leaving tech mid-career is double that of men. What’s more, they’re not leaving to stay at home and mind the kiddies. The majority of women either leave to work outside of tech or go to start their own business. This suggests that though we may have a pipeline issue in attracting women to technology, we have a bigger retention issue.

85% of women in technology say they love their work. Women aged 25-35 cite ‘dissatisfaction at their tech career prospects’ with lack of role models as one of the reasons why.
