Brain gets in the way of thinking

Everyone must have had that experience when you know the word, but suddenly can't remember it, and you say, "It's on the tip of the tongue."
I think of a brain like of a computer with a huge database - the memory. The "tip of the tongue" failure is like a bad link or a search error. Usually if you wait and rest your brain (reboot) or think of just the right clue, you remember the word.

If you have a difficult decision to make and ask someone for advice, people usually tell you, "Follow your heart". The folk wisdom recognizes that a brain shouldn't be relied on in important matters.

The brain stores everything in categories and subcategories in a very orderly way, just like a computer would, to make learning, storing and retrieving information easier. But that creates problems such as stereotyping and discrimination, because when it retrieves data, it comes up packaged in a particular category. So in order to be truly objective we would have to understand how a brain gets information and take it completely out of the context of a category the brain stuck it in.
If we learn to delay and to do that every time we see something, like, for instance, if we see a dirty man stumbling along the sidewalk, we wouldn't immediately label him as "a drunk" and allow for a possibility that he maybe hurt and needs help. Or if we see a spider on the wall we wouldn't automatically scream "danger" and smash that spider with a shoe, but would take a second to consider if this spider is indeed dangerous, and if so, what is the safest method of killing it. Actually, a spider is not such a good example, because even if not dangerous, we may not want it in our living room anyway. The drunk look-alike was a better one, because our brain's automatic response may cause us to walk away from a hurt person.

The brain needs to be used with reservation. I believe its complexity leads people to overestimate its intelligence. But just like with any database, 'garbage-in, garbage out' still applies. We assume that when a brain thinks, it is equivalent to us thinking, but it isn't always the same thing. Most daily activity of the brain is automatic, and thank god it is, because our lives would be hell if we had to think about every step we take and every muscle we need to use during the step. And it makes us capable of learning a huge amount of stuff daily. But when it comes to actually thinking originally and objectively, relying too much on our brain can be detrimental, because it is most likely going to skew and bias our thoughts. Most of the time we have no idea our brain is doing that, and if we are smart enough to suspect it, we don't know what belief system in our programming is distorting our thinking.
