Ever wondered about the adequate portion size of a glass of soda or juice? A bowl of cereals? Or spreads for your sandwich? Maybe you do think about this from time to time, maybe you don't. Chances are, however, that cues around you have implicitly seduced you (they "nudged" you) to have a certain portion size because they set anchors on which you rely to make your own choices. One such cue could be provided by social comparison: you tend to derive information from what others do. For instance, you'll take a bit more than a smaller person or somebody you know to be dieting. These are quite valid cues. But we are also surrounded by biased cues on food packaging. Next time you open the fridge or you're sitting at the breakfast table, you better take a good look and then think about this post.
