The only reason people do not know much is because they do not care to know.

There are young men and women up and down the land who happily (or unhappily) tell anyone who will listen that they don’t have an academic turn of mind, or that they aren’t lucky enough to have been blessed with a good memory, and yet can recite hundreds of pop lyrics and reel off any amount of information about footballers. Why? Because they are interested in those things. They are curious. If you are hungry for food, you are prepared to hunt high and low for it. If you are hungry for information it is the same. Information is all around us, now more than ever before in human history. You barely have to stir or incommode yourself to find things out. The only reason people do not know much is because they do not care to know. They are incurious. Incuriosity is the oddest and most foolish failing there is.

We don’t know enough about ourselves. I think it’s better to know that you don’t know, that way you can grow with the mystery as the mystery grows in you. But, these days, of course, everybody knows everything, that’s why so many people are so lost.

The trouble with the world is not that people know too little; it's that they know so many things that just aren't so.

And yet all I have said is but from common reading. And, let me ask, why, because we know but little, we are to be supposed to know nothing?

People not only don't know what's happening to them, they don't even know that they don't know.

People don't care how much you know unless you know how much you care

The problem ain't what people know. It's what people know that ain't so that's the problem.

much of what other people know isn’t worth knowing.

How it is we have so much information, but know so little?

Yet like many other human traits that made sense in past ages but cause trouble in the modern age, the knowledge illusion has its downside. The world is becoming ever more complex, and people fail to realise just how ignorant they are of what’s going on. Consequently some who know next to nothing about meteorology or biology nevertheless propose policies regarding climate change and genetically modified crops, while others hold extremely strong views about what should be done in Iraq or Ukraine without being able to locate these countries on a map. People rarely appreciate their ignorance, because they lock themselves inside an echo chamber of like-minded friends and self-confirming newsfeeds, where their beliefs are constantly reinforced and seldom challenged.
Providing people with more and better information is unlikely to improve matters. Scientists hope to dispel wrong views by better science education, and pundits hope to sway public opinion on issues such as Obamacare or global warming by presenting the public with accurate facts and expert reports. Such hopes are grounded in a misunderstanding of how humans actually think. Most of our views are shaped by communal groupthink rather than individual rationality, and we hold on to these views out of group loyalty. Bombarding people with facts and exposing their individual ignorance is likely to backfire. Most people don’t like too many facts, and they certainly don’t like to feel stupid. Don’t be so sure that you can convince Tea Party supporters of the truth of global warming by presenting them with sheets of statistical data.

« You only think you know, as a matter of fact. And most of your actions are based on incomplete knowledge and you really don’t know what it is all about, or what the purpose of the world is, or know a great deal of other things. It is possible to live and not know.

Most fools think they are only ignorant.

Ignorance lies not in the things you don't know, but in the things you know that ain't so.
