We need feedback, they say. Not when you’re on the radio, of course, the delay through the transmission process will cause your own voice to return later and echo through the same process. Not when you’re singing on stage, either, as you’ll get a high pitched tone as the mic and amplifier picks up its own signal from the speakers, causing a positive feedback loop. That’s no good. But all other times, feedback is what we want. Is that right? We want feedback?
If the bad kind, on stage, in broadcasting, is bad because it is
positive feedback, then what is
negative feedback? That’s all over the place too — technology is full of negative feedback systems, for correcting deviations, etc. Aircraft navigation and flight controls use negative feedback to ascertain how far off course we are, how far out of the desired steering the plane is, etc. At home, the central heating has a thermostat which uses negative feedback — is it at the correct temp yet? No, then keep heating. Is it at the correct temp yet? No, then keep heating. Is it at the correct temp yet? Yes, then stop doing what it’s doing — stop heating. Most systems we use all day use negative feedback for correction and control, it’s an essential part of modern system design, from
cybernetics to signal theory (see
Claude Shannon’s work, if you’re interested in that sort of thing).
What about us? In business, in real life? Do we need feedback? Which sort? Are we
cybernetic systems, designed to operate through error correction via a negative feedback loop? I would suggest it’s not that simple. Yes, we operate mechanistically in many ways, but not totally. We are subject to the mass reinforcements of feedback that amplify, exaggerate and ramp up the input to increase the output that are all typical of an out-of-control positive feedback loop. When we’re told of news of a bank that’s perhaps on shaky ground and there’s a slight risk that in the distant future it may fail, we all queue up at the doors to get our money out, and guess what, the bank fails. It’s that horrid positive feedback again, isn’t it.
What about negative feedback. Our lives are full of that. You need not look any further than our partners or spouses to find a constant and reliable source of negative feedback. Corrective criticism designed to adjust what we’re doing can obviously improve the outcome. Anyone involved in quality control in mass production knows this — if there’s an issue or fault, detecting it, measuring it, and bringing this evidence to the source of the error as negative feedback will hopefully adjust and correct the error, so that subsequent production is within tolerance. That’s pretty normal for modern production in most industries.
However, although the negative feedback loop indubitably works so well for keeping systems under tight control, is it the way humans work? To a certain level, yes of course. If you’re learning something, or training someone, highlighting errors or incorrect actions will hopefully cause subsequent attempts to occur within acceptable boundaries. Learning a musical instrument, a language, a sport, etc. You want to know what you’re doing wrong, and in quite significant detail, otherwise you’ll continue doing it, perhaps never knowing why things aren’t turning out quite right.
However, as hinted at in reference to partners, there’s a tendency to think that if negative feedback achieves so much good, then just keep doing it, and doing it more! Not just partners, but work colleagues, everyone we are in contact with in fact. Of course, that falls into the category of positive feedback and escalates to a level of saturation representing the most that we can put up with. Occasionally, though, that top level is reached and broken, so people split up, people walk out of jobs, people shout at customer service workers, people even go out on strike and have marches.
What about positive feedback as the antidote? If used carefully, it can be a good thing, it can be a reinforcement, an encouragement, and an ingredient for growth. As referred to earlier, 100% positive feedback is no use. Telling someone they’re fantastic all the time when they’re not is really unproductive and can be damaging, but never telling people they’re doing okay when they’re doing okay is also unhealthy. You can achieve a lot with negative feedback but you can’t go all the way with just nothing but criticism, and similarly you can have quite damaged outcomes with nothing but positive feedback but used now and then it’s quite a good ingredient.
What about no feedback at all? Well, there I think is the biggest problem. People working alone or at home or teleworking or setting up new businesses on their own, are at risk of having absolutely no feedback at all. Most feedback you’ll get from the Internet is simply non-existent — no feedback at all — you’ll be totally ignored. You don’t exist. Your efforts add up to nothing.
The next level of feedback is simply a simple “+” or a “like”, which might well only indicate that the person reading it didn’t disagree with it and wants some way of remembering it later, on that fictitious day that they’ll come back to everything they’ve ever bookmarked and read some of it again (I don’t know, maybe the
Internet firehose dried up that day, nobody posted new stuff, so we all have to read some old stuff). The Internet is a strange and unintuitive system when it comes to feedback design principles. There’s a lot of positive feedback tendencies about it — things can ramp up out of control very quickly, “
going viral” as they say (in reality it’s more like a
stampede than a virulent outbreak) and then it’s old news, buried forever like
Crazy Frog or
All Your Base Are Belong To Us. There’s no shortage of negative feedback on the Internet either — you don’t have to look far to find maximum criticism occurring any day of the week.
But the risk of working on your own is that there’s absolutely no feedback at all — your efforts might be good, or might need adjustment, but the particular response curves of the system are simply not linear (technically, there’s
hysteresis, which is partly the reason things can go viral) and this lag or disconnection can be disconcerting, depressing and give the impression that you’re being completely ignored.
We need feedback — to tell if we’re on the correct path or not. Without feedback we might think we’re doing okay but we’re really heading off in an incorrect direction. Or worse, without feedback we don’t get any validation that what we’re doing amounts to anything worthwhile at all, so we stop wasting our time on it and do something else instead, or at least, slow down, in case it turns out to be a waste of time.
If you’re doing your own thing, if you’re working alone, if you’re not part of a group, then there’s an additional resource drain of having to have faith that what you’re doing might one day add up to something. Even when in the face of things, there’s nothing complete right here and right now, and the whole world is ignoring you, giving no feedback at all — neither positive nor negative — just nothing. It’s under those circumstances that we must remember what we’re doing and fix our sights on the eventual outcome — the goal, the destination, the thing we’re doing it all for. We have to be our own feedback loop.
