Our intelligence is always imperfect.
To err is human, to persist is diabolical.
The original latin: Errare humanum est, sed perseverare diabolicum.
No man so wise that he may not easily err if he takes no other counsel than his own. He that is taught only by himself has a fool for a master.
Our perceptions are fallible. We sometimes see what isn't there. We are prey to optical illusions. Occasionally we hallucinate. We are error-prone.
My experience is that our intelligence officials try to do the right thing, but even with good intentions, sometimes they make mistakes. Sometimes they can be overzealous.
Errors using inadequate data are much like those using no data at all.
Everybody generalizes from one example. At least, I do.
Making mistakes is human ... repeating 'em is too.
People and companies make mistakes. I guarantee we'll make a mistake next quarter. So what? Businesses make mistakes. Hopefully smaller, and fewer.
We never are definitely right, we can only be sure we are wrong.
I don't think that we are a species or a people that can exist without making mistakes somewhere along the line.
I am indeed amazed when I consider how weak my mind is and how prone to error.
Men were not intended to work with the accuracy of tools, to be precise and perfect in all their actions.
I make mistakes like the next man. In fact, being--forgive me--rather cleverer than most men, my mistakes tend to be correspondingly huger.
... the fallibility of human brains is in nothing more obvious than in proof reading.
In no other branch of mathematics is it so easy for experts to blunder as in probability theory.
Objectivity consists in understanding that the only one who never makes a mistake is the one who never does anything.
It is much easier to meet with error than to find truth; error is on the surface, and can be more easily met with; truth is hid in great depths, the way to seek does not appear to all the world.
Hurry n: The dispatch of bunglers.
When it comes to their capacity to screw things up, computers are becoming more human every day.
All men are liable to error; and most men, in many points, by passion or interest, under temptation to it.
Any verbose and tedious solution is error-prone because programmers get bored.
I have so often been mistaken that I no longer blush for it
If you are doing something wrong, you will do it badly.
Always there should be a little mistake here and there - I am for it. The people who don't do mistakes are cold like ice. It takes risk to make a mistake. If you don't take risk, you are boring.
