“Media understanding about probability, margin of error and uncertainty is very poor,”

I've been saying for years that you should have to take at least two semesters of stats for a degree in journalism... then I found out that in most programs, they ARE. So now I've changed my requirement to say that you have to actually PASS. Because when I read even "good" journalism, it is clear that most journalists can't do any stats beyond calculating percentages, and in at least 1/4 of the cases, they don't even use percentages right (i.e. they are blind to built-in assumptions and obvious bias).

I think, sadly, most journalists are basically innumerate.

He gave Hillary Clinton roughly a 7 in 10 chance of winning, with Trump at about 3 in 10.

People kept saying "Trump doesn't have a chance" and I kept trying to point out that to come up with that number, 538 ran the election simulation 10,000 times and over 3,000 times Trump won, which means that, yes, he does stand a chance. To me, those types of numbers make it a nailbiter.

I like to ask people something like: "You have a revolver that holds 10 bullets. It's loaded with 3. How much do I have to pay you to play Russian Roulette with that gun?" The all of the sudden people start to think 3 in 10 is pretty high probability.

What I found interesting was that Silver said the polls were good.  I thought they were somewhat off the mark ....or maybe that's how they were being represented by the media that was reading them with a bias.

> How much do I have to pay you to play

In senior-level college courses I took an experimental course, Decision Theory, in lieu of stats. Best course ever.  Basically, you had to assign "much do I have to pay" to each branch of a decision tree.

The issue is not just a lack of understanding, but also more incendiary & absolute headlines are more likely to be spread by home team (who love it) and away team (who are outraged by it).

The guy who mentions

The margin of error on the poll between x and y is 3% and the vote appears to be in a near dead heat with 44.9% for x and 55.1% for y



that guy will get nowhere near the spread / virality of his story as the person who slants coverage to talk about how this person is racist or historically the vote has been this way and the key vote segment z etc etc etc

ultimately people want to read people rooting for their side, so that's what they get.

and thousands of local newspapers disappear
