"Mistakes" is easy to judge when other do it and difficult to realize when we do it.

Most errors in judgment happen when we don’t know we’re supposed to be exercising judgment.

Good decisions aren’t always rational.

Your first mistake might be assuming that people are rational.
Your second mistake could be assuming that people are eager for change.
And the marketer's third mistake is assuming that once someone knows things the way you know them, they will choose what you chose.

Not only bad decisions are made on false assumptions. Sometimes when things go right, we think we know why, but do we really? That the result went the way you wanted does not mean you can repeat it over and over.

"Mistakes". Easy to judge when others do it and difficult to realize when we do it.

Most people suspend their judgment till somebody else has expressed his own and then they repeat it. Common parlance alludes to this weakness in the frequently heard phrase: PEOPLE DO NOT THINK.

Thinking is difficult, that’s why most people judge.

A mistake constantly made by those who should know better is to judge people of the past by our standards rather than their own. The only way men or women can be judged is against the canvas of their own time.

A mistake in judgment isn't fatal, but too much anxiety about judgment is.

People judge what they do not understand

I often make the mistake of thinking that something that is obvious to me is just as obvious to everyone else.

Sincerely believe that you might not know the best possible path and recognize that your ability to deal well with “not knowing” is more important than whatever it is you do know. Most people make bad decisions because they are so certain that they’re right that they don’t allow themselves to see the better alternatives that exist. Radically open-minded people know that coming up with the right questions and asking other smart people what they think is as important as having all the answers. They understand that you can’t make a great decision without swimming for a while in a state of “not knowing.” That is because what exists within the area of “not knowing” is so much greater and more exciting than anything any one of us knows.

How do people make the judgments and how do they assign decision weights? We start from two simple answers, then qualify them. Here are the oversimplified answers: People overestimate the probabilities of unlikely events. People overweight unlikely events in their decisions.
