A simple way to evaluate a company's potential

Quoting from Darci Riesenhuber's quoting of Tom Peters on the Top Peters! blog: "LOOK AT A DAMN PICTURE OF THE BOARD OF DIRECTORS IN THE ANNUAL REPORT ..."

For a bit more explanation, see "Firms With More Women on Boards Perform Better Than Those That Don’t." Yes, I know: correlation and causality are different things. I suspect that the changes in a company's culture that would be necessary to get more diversity on a board are also those that would drive the changes that would lead to the reported results.

Other data, anyone?
