The Role of Expectation On Taste

This is especially the case with foods. Over time, we've seen plenty of studies that show how our expectations change our perception of taste.

For example,one study published in Food Quality and Preference tested the role of expectation on taste using smoked salmon flavored ice cream (yes, you read that correctly).

They found when people read the label "ice cream", they disliked it and found it salty and savory. When they labeled it "frozen savory mousse," people liked it more because they weren't expecting the usual sweetness of ice cream.

The way we anticipate something changes the way we perceive it... It suggests that the way the brain works is to influence our perception. If our perception has been established without the information from the brain, the information of the brain is no longer relevant...

If you think about it more generally, there's a question about how our preconceived notions color our view of reality... what happens when we view the world with glasses that are strongly tinted by our preconceived notions?

 What these results suggest is an interesting connection between the body and the mind... it suggests our mind tries to predict the future... by anticipating the future the mind actually changes our physiology... it prepares us for that future. By doing so the mind basically gets us to experience the reality that we anticipate.
