Absence Blindness is a cognitive bias that prevents us from identifying what we can’t observe. Our perceptual faculties evolved to detect objects that are present in the Environment. It’s far more difficult for people to notice or identify what’s missing. Examples of Absence Blindness are everywhere. Here’s a common example: great Management is boring — and often unrewarding. The hallmark of an effective manager is anticipating likely issues and resolving them in advance, before they become a problem. Some of the best managers in the world exhibit a quiet sort of competence: there’s little drama, and everything gets done on time and under budget. The problem is, no one sees all of the bad things that the great manager prevents. Less skilled managers are more likely to be rewarded, since everyone can see them “making things happen” and “moving heaven and earth” to resolve issues — issues they may have created themselves via poor Management.

Experience helps in terms of being able to do the job in a satisfactory manner so when people see your experience play out, ideally they acknowledge your skillset and give you more opportunities.

The value of experience is not in seeing much, but in seeing wisely.

Experience - the wisdom that enables us to recognise in an undesirable old acquaintance the folly that we have already embraced.

Experience is what you get when you didn't get what you wanted. And experience is often the most valuable thing you have to offer.

We all have blind spots in our knowledge and opinions. The bad news is that they can leave us blind to our blindness, which gives us false confidence in our judgment and prevents us from rethinking. The good news is that with the right kind of confidence, we can learn to see ourselves more clearly and update our views. In driver’s training we were taught to identify our visual blind spots and eliminate them with the help of mirrors and sensors. In life, since our minds don’t come equipped with those tools, we need to learn to recognize our cognitive blind spots and revise our thinking accordingly.

Experience is a keen teacher;

Experience enables you to recognize a mistake when you make it again.

Experience is indeed essential to science, but its role is different from that supposed by empiricism. It is not the source from which theories are derived. Its main use is to choose between theories that have already been guessed. That is what ‘learning from experience’ is.

Advice can never take the place of experience. That which advice can sometimes do is to make experience more fruitful of good; to help us the better to understand the lessons of life; and when those lessons are sharp and unwelcome, to bear them with an even and unruffled mind.

The power to guess the unseen from the seen, to trace the implication of things, to judge the whole piece by the pattern, the condition of feeling life, in general, so completely that you are well on your way to knowing any particular corner of it — this cluster of gifts may almost be said to constitute experience, and they occur in country and in town, and in the most differing stages of education. If experience consists of impressions, it may be said that impressions are experience, just as (have we not seen it?) they are the very air we breathe. Therefore, if I should certainly say to a novice, "Write from experience, and experience only," I should feel that this was a rather tantalizing monition if I were not careful immediately to add, "Try to be one of the people on whom nothing is lost!"

What is the one asset, the one benefit you have today over yesterday? The answer, of course, is experience.

"They keep telling you, when you’re older, you’ll have experience — and that’s supposed to be so great. What would you say about that, sir? Is it really any use, would you say?"

"What kind of experience?”

“Well — places you’ve been to, people you’ve met. Situations you’ve been through already, so you know how to handle them when they come up again. All that stuff that’s supposed to make you wise, in your later years.”

“Let me tell you something, Kenny. For other people, I can’t speak — but, personally, I haven’t gotten wise on anything. Certainly, I’ve been through this and that; and when it happens again, I say to myself, Here it is again. But that doesn’t seem to help me. In my opinion, I, personally, have gotten steadily sillier and sillier and sillier — and that’s a fact.”

“No kidding, sir? You can’t mean that! You mean, sillier than when you were young?”

“Much, much sillier.”

“I’ll be darned. Then experience is no use at all? You’re saying it might just as well not have happened?”

“No. I’m not saying that. I only mean, you can’t use it. But if you don’t try to — if you just realize it’s there and you’ve got it — then it can be kind of marvelous."
