Do you know the feeling you get in the pit of your stomach when you're wrong?

That's not what it feels like.... that's what it feels like after you learn you were wrong. There's no difference in feeling between being right or wrong. So, if you want to be right more often (a proxy for being "smarter), I suggest the following.

Write down predictions somewhere, along with your view of the world, things you're worried about, etc. Keep it private, but be as descriptive as you can to yourself, as time goes on, you can then retrospectively see where your biases and fears have distorted your thinking, and find clues to the things you were right about, but too afraid to follow up on. Over time, you should gain both perspective and wisdom, and perhaps a bit of "smarter" as well.
