Past, Present, Future
I can’t remember who said it, but;
Feedback is information given in the present about behavior in the past that can be used to modify behavior in the future.
Just because feedback can be used to modulate future behavior doesn’t mean it actually will be used. Depending on the quality of the relationship between the feedback provider and the feedback receiver, the feedback may be taken to heart or it may be ignored. If the feedback receiver has little respect for the feedback provider, regardless of whether the provider is the receiver’s so-called “superior”, the feedback will be ignored. Oh sure, the receiver’s behavior may appear to superficially change out of fear, but counterproductive behind-the-scenes behavior will be guaranteed if the feedback is delivered as an “or else” ultimatum. On the other hand, if there is a two way connection of respect and trust between provider and receiver, the receiver’s behavior may change – if the receiver agrees with the provider’s assessment and it strikes an emotional chord within the receiver’s being.
Emotional energy, not logical deduction, is the driver of behavior. So stop being puzzled when people don’t behave “logically”.
