Given how much HN loves to bring up the studies that show people fail at tasting wine, it's surprising that nobody has talked about how double blind studies consistently reveal that there's no perceptible taste difference between different types of eggs (once color is controlled for): Washington Post: > The egg industry has been conducting blind tastings for years. The only difference is that they don't use dish-towel blindfolds; they have special lights that mask the color of the yolks. "If people can see the difference in the eggs, they also find flavor differences," Curtis says. "But if they have no visual cues, they don't." > Only one factor can markedly affect an egg's taste, and that is the presence of strong flavors in the feed. "Omega-3 eggs can sometimes have a fishy taste if the hens are fed marine oils," http://www.washingtonpost.com/wp-dyn/content/article/2010/06/01/AR2010060100792.html http://www.washingtonpost.com/wp-dyn/content/article/2010/06... Serious Eats: > It was pretty clear evidence that as far as eggs go, the mindset of the taster has far more bearing on the flavor of the egg than the egg itself. http://www.seriouseats.com/2010/08/what-are-the-best-eggs-cage-free-organic-omega-3s-grocery-store-brand-the-food-lab.html http://www.seriouseats.com/2010/08/what-are-the-best-eggs-ca... Journal of Product and Brand Management: > Respondents indicated that darker yolk color results in better taste, whereas results of a blind taste test indicated that consumers were not able to distinguish any significant difference in the taste of different types of eggs and yolk colors (Fearne and Lavelle, 1996b). Similarly, respondents indicated that brown regular and specialty eggs are tastier than white regular eggs. Fearne and Lavelle (1996b) reported that in a blind test consumers could not make a distinction between the tastes of regular and specialty eggs. http://ps.oxfordjournals.org/content/90/5/1088.full http://ps.oxfordjournals.org/content/90/5/1088.full It's an extremely potent example of confirmation bias since even people who are normally quite science minded and skeptical somehow find loopholes that exempt their personal experience as not conforming to the data when confronted with evidence that their fancy eggs taste no better.
