The idea that 7% of American adults like lying on surveys is more believable to me than the idea that people think chocolate milk is not from added chocolate.

That would be a relief. The number of customers that will continue to bank at Wells Fargo, however, suggests not only that the respondents didn't lie, but that the model was likely too conservative.

This is technically correct (the article notes this). Milk of all kinds comes from all cows. Some fraction of chocolate milk comes from brown cows.

Aren't some cows brown?
