Or even visiting a museum? Being questioned by your child as to why something is? Deciding wo to vote for? I could go on.
What if you're taking a history class?
These are all matters of interest.
If you are interested in history you are more likely to take history classes, have a conversation about history, or visiting a museum.
This is for you leisure time, like literature.
How is literature useful?
It isn't, but it is part of the "culture", and people are interested in it.
example : History is determine to decide your support and vote for a president that is pro Israel government or not pro Israel government, or not to support any of it at all.
To make a fair judgement or treatment about someone ideology, religious believe, etc so you don't act upon prejudgement or paranoid attitude hence from your poor history knowledge or your wrong understanding about their history.
Even to understand most of knowledge you sometime need to know the history about this certain knowledge, so you can get a better grasp understanding about it.
Your character and your perspective that make you who you are is a result on how you understand and believe what happen in the past that make you what you are now in present and what you aim in the future.
And arguably most public miss perception, violent, and civilization clash also results on wrong understanding of history, or manipulation toward history or how the authority dictate their story as history.
A problem between Chinese peoples, Korean with Japanese, the sentiment and all that stuff also regarding on how difference they see history. And you can add another example, which are many.
So history is not just good story that is not right at all you try to degrade it too much, then what is the difference between "Man and super man" novel by Bernard Shaw which I consider funny and nice with historical book? if it the same, tell me how is it the same?
History is an important part that shape ideology or way of life that is why it useful.
In fact, we need more historian, a good honest apolitic and fair historian.
There is a difference between the narrow and minimal knowledge of history you need as a normal man who votes, to a real knowledge in history.
For example, the knowledge I need as a citizen in order to vote in Israel is very minimal.
Just a little about the founders of the state and Zionist activists, some more the Holocaust, a little about the biggest political events in Israel in the last 30 years, and about wars between Israel and neighboring Arab states. That's it.
Of all the global history, this is what I need in order to form my political view.
(Of course I'm not like that, but this is my choice, and most people are more like what I mentioned above)
If you want to be a visionary you will need some more, but I don't believe you'll need anything earlier than WWI, and even in those 100 years, you'll only need to know about the Middle East/Europe/USA.
Because the rest didn't affect you at all today
(from Israeli point of view, as an example..)
(It technically did affect you because one thing led to another, but I'm talking about ideology and politics)
And of course it is not only in Israel.
I can't claim to know it for sure, but it doesn't seem to me that an American needs to know much as well.
Very little about the existence of pre-columbians, very little about the colonialism / early USA, and more about post civil war America (including recent Europe history - WWs and cold war).
What else is needed for a regular American citizen?
I'm not talking about people who have interest in history.
Deep history is not being taught in order to make the world a better place.
It has cultural or national motives.
And it is also part of men's curiosity, and pride - to discover more and more.
People who are interested in history can see it as more than that, and it is understandable.
But most people doesn't
have to know
much history.
