unit bias
You consume the entire portion regardless of the amount.
Unit bias is the tendency to consume a single discrete unit of an item (such as one brownie or one scoop) regardless of its size, whereas the phenomenon of consuming more due to larger plates is known as the portion size effect.
The provided supporting text misattributes the plate-size effect as evidence for unit bias.
Your appetite is governed by the size of your plate, not your stomach.
