I have posted links to journalists speechifying (since there does not appear to have been any other studies carried out). In one case I even acknowledged that there would be bias, which I think is more than you have done when telling us the results as per your McKinsey gospel.

But as usual, pick on one thing, lead the actual discussion away from the original topic and bog it down with proving a point, or convincing others your point is valid. I guess one difference would be that you seem to care....I don't. It is just typing.
