Knowledge Ventriloquism
Ken Zeichner takes us inside the teacher prep war echo chamber

Ken Zeichner: It’s a particularly useful concept these days. Basically what you have is an echo chamber effect where think tanks and other advocacy groups just keep repeating each other’s claims until they become true. There’s a research component too, except that the research isn’t independent. In fact, you can usually predict what the findings are going to be be based on who is doing the research. Cherry picking is another essential component of *knowledge ventriloquism.* Advocates of a particular position or program will selectively choose certain findings and ignore others. The problem is that by the time any of this reaches the mainstream media and the headlines, any nuance or complexity is lost.
