Negative feedback feeds part of a system's output, inverted, into the system's input; generally with the result that fluctuations are attenuated. Many real-world systems have one or several points around which the system gravitates. In response to a perturbation, a negative feedback system with such point(s) will tend to re-establish equilibrium.
In many physical and biological systems, qualitatively different influences can oppose each other. For example, in biochemistry, one set of chemicals drives the system in a given direction, whereas another set of chemicals drives it in an opposing direction. If one, or both of these opposing influences are non-linear, an equilibrium point(s) results.
In Biology, this process (generally biochemical) is often referred to as Homeostasis; whereas in Mechanics, the more common term is equilibrium.
In Engineering, Mathematics and the Physical and Biological Sciences, common terms for the points around which the system gravitates include: attractors, stable states, eigenstates/eigenfunctions, equilibrium points, and setpoints.
'Negative' refers to the sign of the multiplier in mathematical models for feedback. In delta notation, -Äoutput is added to or mixed into the input. In multivariate systems, vectors help to illustrate how several influences can both partially compliment and partially oppose each other.
In contrast, positive feedback is a feedback in which the system responds in the same direction as the perturbation, resulting in amplification of the original signal instead of stabilizing the signal. Both positive and negative feedback require a feedback loop to operate, as opposed to feedforward, which does not rely on a feedback loop for its control of the system.

“Jane, you ignorant slut.” No one who heard Dan Ackroyd make that statement on the early Saturday Night Live shows had any doubt that he was about to strongly disagree with whatever Jane Curtin had just said. The problem was he was going to disagree not with what was said, but with who said it. That's not the way to give negative feedback.

Here's How:
Get your emotions under control. You don't want to critique someone else's actions when you are angry or upset. You are likely to say something you don't really mean or to react poorly to something that is said to you.
Find a private place. No one wants to receive negative feedback in front of others. Sometimes it is unavoidable, but that should be a last resort. Take a meeting in your office, call the person into a vacant conference room, step into the lunch room if it is vacant.
Focus on their actions, not on the person. You create an immediate barrier when you criticize the person. Focus instead on what you want to change. Focus on their performance.
Be specific. It does no good to tell someone 'you have a bad attitude'. You need to identify specific actions the person took or specific things they said if you want them to understand.
Be timely. Negative feedback should be given as soon as possible after the event. If you see an employee being rude to a customer, don't wait until their annual performance review to tell them. How many other customers will they have angered in the meantime? Call them into your office right away.

Good feedback is rare. It can take a long time to find people who know how to provide useful criticism, instead of simply telling you all the things they think are “wrong” with you or whatever you've made. A good critic spends as much energy describing what something is, as well as what it isn't. Good criticism serves one purpose: to give the creator of the work more perspective and help them make their next set of choices. Bad criticism uses the opportunity provided by someone else's work to make the critic feel smart, superior or better about themselves: things that have nothing to do with helping the recipient of the critique (Or in the case of movie reviews, the reader of the critique). Given the difficultly of creative work, it would seem that giving and receiving useful feedback should be an important part of what designers, writers, programmers and others are taught to do. This essay attempts to serve that purpose.
Assumptions bad critics make
There are four fundamental assumptions bad critics make:
There is one universal and objective measure of how good and bad anything is.
That the critic is in sole possession of the skill for making these measurements.
Anyone that doesn't possess this skill (including the creator of the work) is an idiot and should be ridiculed.
That valid criticisms can and should always be resolved.

Abstract
This article discusses why it is so hard for people to benefit from negative feedback. We examine
factors involved in the effective use of negative feedback. Our analysis suggests that the main
obstacles to the effective use of negative feedback stem from the failure to obtain it and the failure to
conduct an accurate appraisal of it. This is in contrast to research indicating that the main obstacle to
the effective use of positive feedback lies more in avoiding its detrimental consequences after repeated
exposure to it than in obtaining it or appraising it.
1. Introduction
Feedback research is a mature field of inquiry that offers excellent literature reviews of
specific stages of the feedback process. However, although the feedback literature considers
sign to be one of the most important characteristics of the feedback message, theoretical
models give little attention to the specific issues raised by positive versus negative feedback
(Fedor, 1991; Ilgen, Fisher, & Taylor, 1979; Larson, 1989; Morrison & Bies, 1991). Yet,
empirical evidence suggests that positive and negative feedback affect people quite differently.
For example, research shows that the sign of the message affects the availability of
feedback in that negative feedback is less sought after and less readily provided than positive
feedback (Fisher, 1978). Other work indicates that individuals are generally receptive to
positive feedback but tend to discredit negative feedback concerning their performance
(Baron, 1993).
Acknowledging the importance of feedback sign in the feedback process, this paper
focuses on factors that prevent people from benefiting from negative feedback. We develop a
three-step model of the processes underlying the effective use of negative feedback and
identify some of the critical contingencies affecting such processes. Our theoretical analysis
revolves around the three following aspects: (1) the search for negative feedback; (2) the
appraisal of negative feedback; and (3) the action taken in response to negative feedback.
To anticipate our conclusion, our theoretical analysis suggests that the main obstacles to
the effective use of negative feedback stem from the first two factors, the failure to obtain it
and the failure to conduct an accurate appraisal of it. This is in contrast to the research which
indicates that the main problem in effectively using positive feedback lies primarily in
avoiding the detrimental consequences resulting from repeated exposure to it (for a review,
see Kluger & DeNisi, 1996). It must be noted that our review of previous work is selective
rather than exhaustive. We limit our task to identify some of the unique problems posed by
negative feedback.
We begin by reviewing previous work on the search for negative feedback. We then move
the analysis to the other two steps, appraisal of and the action response to negative feedback.
We conclude with a discussion of theoretical and practical implications and directions for
future research.

Giving negative feedback sucks. Period. It's uncomfortable for you and it's uncomfortable for the person hearing it. But no matter how much you twist and turn to avoid it, giving negative feedback may be the kindest way to change behaviour. And believe it or not, there are ways of delivering it that make it less painful for all parties involved.

Your team is complaining - Tony's smelly feet are putting them off their work. What do you do? Ignore it? Open the window? Or do you talk to Tony?
So you decide to ignore it. What happens then? Your team thinks you don't listen to them and gradually your communication channels shut down. Ignoring the issue is not going to make it go away.
You decide to open the window, as you don't want to embarrass Tony. Problem is that most modern office windows don't open so that the air conditioning works. Even if you could open the window, you've avoided tackling the real problem.
So you pluck up the courage to have a chat with Tony. From this you discover he has recently split up from his partner and has been sleeping on a friend's couch and living out of a ruck-sack. No-one in the team knew this, and Tony didn't know how to mention it. You chat about the situation and Tony feels better for it. Bet you didn't expect that to happen!
(This is a real example - names have been changed to protect identities.)
This conversation could have gone horribly wrong. But it didn't as it's possible to give negative feedback well.
