Can you judge the book by its cover?

The common wisdom tells us that you can't. But yet it's so commonly practiced, out of necessity. If there are hundreds of books you need to digest, can you read all and judge it by contents? If there isn't even enough time for you to digest, can you spare additional time to judge it by contents? It's not impossible if you have endless energy and time.

Yet you cannot just simply judge the book by its cover and that's it. There's only two possible outcomes, you either judge it correctly, or wrongly. It's important to know why is that so. Maybe you can include other factors like thickness, published year, where you get it from and ec cetera. Case after case, you may have develop a database (experience) to help you make better judgement. I think this is essential to help me to deal with people more efficiently.

It's actually similar to what has been described in previous article, it's the feedback that is most important.

Perhaps I did too much analysis on closed loop feedback system. :)

Just my two cent thought.
