Biases and human intelligence

• People who are aware of their own biases are not better able to overcome them. Our intuitive thinking is just as prone to overconfidence, extreme predictions, and the planning fallacy.
• According to scientists, intelligent people have a larger bias blind spot. They can spot systematic flaws in others, but not in themselves. They will excuse their own minds but harshly judge the minds of other people. 

We’re not nearly as rational as we like to believe. When we face an uncertain situation, we fail to evaluate the information or to look up relevant statistics carefully.
Instead, we depend on our mental shortcuts which may lead us to make rash decisions.
