Feedback is factual information that we give back to people or that we receive from the environment with respect to an action we have taken or a certain decision we have made. It does not concern the person and his attributes, and it is specific, that is, it refers to something that happened at a precise moment and in a well-defined context.

However, feedback and criticism are often placed on the same level. Criticism, understood as praise when it is positive or, as blame, when it is negative, is a personal judgement on behaviour or a result that almost never has the effect of allowing the recipient to understand something more about himself.

This is why we are reluctant to ask for information and to accept any advice that will end up calling into question our image and our abilities. Criticism is a reason for personal failure. If an individual, adult or child, is judged or penalised excessively harshly for his/her mistakes and failures, he/she will tend to reinforce his risk aversion and make superficial and prudent choices.

Feedback, on the other hand, is “the breakfast of champions”. The nourishment of growth, a cognitive support, because it allows us to think together, in a dialogue, to correct mistakes and prevent any failures. Failure is itself feedback that points people in the right direction.
Feedback needs to be frequent and targeted. In fact, a broad consensus of literature on the subject confirms that the two characteristics capable of making learning through feedback effective are content and timing.

Feedback given incorrectly, infrequently and of doubtful quality may be the cause of counterproductive results. Not giving proper feedback or refusing to accept it may compromise our chances of success. People who are not willing to question themselves fail.
