Embrace meta-rationality. Know the limits of your own understanding, know when to consult experts, which experts to defer to, and when to admit that something is impossible for anyone to know.
Allow for uncertainty. Confident statements seem more promising but are open to hidden risks.
Seek fingerspitzengefühl, roughly translated as intuitive knowledge. We all have some areas where we have a deep knowledge. We have to learn not to overestimate our own knowledge. To avoid overconfidence bias, learn more about your field of expertise.
Build in a margin of safety. When an engineer designs a bridge that can support up to 100 cars at a time, they plan to hold a multiple of that amount, 200 or 300, as a margin of safety.
Unconscious bias refers to unconscious forms of discrimination and stereotyping. Unconscious bias often leads to discrimination, be it deliberate or unintentional.
Unconscious bias is different from cognitive biases. Cognitive biases relate to our brains' particular wiring, while unconscious bias refers to perceptions between different groups and are specific to different societies.
The curse of knowledge is a cognitive bias that causes people to fail to account for the fact that others don't know the same things that they do. Essentially, this means that people who are more knowledgeable than others in some domain will generally struggle to act in a way which properly takes this difference in knowledge into account.
