Do You Judge a Book by Its Cover? Be Honest.

[Heaven]

No, I don't think that's a good thing because you didn't read the book deeply and you don't know what it says, and most people judge someone in real life that you don't know.
This is the same question for you?

[Shawn]

I think when it comes to actual books, I do.

I don't with people, though.

I'm probably missing out on some good books, too.

[Heatman]

Yes, I do. You can't have a book with good content killed off with a bad cover.

The book's cover is more like what invites someone to take a look/glance and then proceed to buy and read it.
