FEEDBACK PEDANTRY….Vikas Bajaj of the New York Times explains the financial crisis:

The technical term for it is “negative feedback loop.” The rest of us just call it a panic.

I know that a lot of people use this term during a crash because “negative” is the same thing as “down,” but I don’t think this is right. It’s a positive feedback loop he’s talking about, where every action in a particular direction feeds back to cause even greater action in the same direction. In a bubble, it means that the market going up causes buyers to get ever more excited, causing the market to go up even more. In a panic, it means that the market going down causes sellers to get ever more hysterical, causing the market to go down even more. It’s bad news in both directions, and it’s a positive feedback loop whether that direction is up or down.

Unless, of course, this is some kind of weird term of art in the finance biz. Which would probably serve me right. Anyone know?

DEMOCRACY DOES NOT EXIST...

without free and fair elections, a vigorous free press, and engaged citizens to reclaim power from those who abuse it.

In this election year unlike any other—against a backdrop of a pandemic, an economic crisis, racial reckoning, and so much daily crazy—Mother Jones' journalism is driven by one simple question: Will America will move closer to, or further from, justice and equity in the years to come?
