This question already has an answer here:
At at TV quiz game they claimed that about 16 millions adult Americans believe that chocolate or cocoa milk drinks are milked from brown cows.
As it is unbelievable I've quickly searched for it and found other similar claims. For instance https://www.google.com/amp/s/www.independent.co.uk/life-style/food-and-drink/american-chocolate-milk-brown-cows-study-us-dairy-innvoation-adults-a7793016.html%3famp
Is that possible/true? Is the source of the study a reliable one or this is just time killing humorous and somehow it got mirrored by the Internet or entertainment TV channels?
