Your Brain’s Shortcut to protect itself
I’m sure you know by now, that we humans, do crazy things. Any studying of psychology and the sub-conscious will quickly show you this. We do things that, in hindsight don’t even make sense. Like-at all. One thing we do that has always fascinated me is called confirmation Bias. By definition it is:
The tendency to search for, interpret, favor, and recall information in a way that confirms one’s pre-existing beliefs or hypotheses. -Webster Dictionary
We try and seek out information that confirms our beliefs about ourselves.
An example of this is when you’re home feeling lonely or bored, you might hop on Facebook and browse pictures of people having fun and being social. You want to confirm to yourself that you’re missing out and lonely. Your brain wants to match your heart, feelings, and emotions for some reason. It’s confirmation bias at work.
Likewise, when you fall in love — all you see is perfection. You don’t care about their flaws, if you notice them at all. Then all the sudden, when you fall out of love, you notice every flaw and think oh I was wrong about them, they aren’t good for me. Your perspective changes to favor and match your feelings of the moment. This happens subconsciously, all the time, day after day — to everyone.
