MIT has been conducting a study on disfunction for thirty years. In it the participants are assigned to different levels of distribution. As the experiment goes along, the subjects experience greater and greater scarcity of the product they’re shipping.

Nine times out of 10, this results in the participant blaming the person(s) above her in the process. The retailer blames the wholesaler. The wholesaler blames the factory. And it all comes back to bite the customer, who is just trying to buy her toothpaste.

Blame puts up dividers. It’s a great, easy and cheap way to build walls.
