decision database in your brain
Our decisions are greatly affected by our past experience and knowledge. I noticed that at work, more senior engineers often see bigger picture i.e. of problems we encounter. Because they might have come across then previously, they can act very fast when necessary. On the other hand, we know that our beliefs might be biased.
How does one gain knowledge that is not biased? Is it the case of always acting on data and using it in the future only if the situation is roughly the same? I guess this might be it, I remember that my manager told me once:
if I told you it is raining, you go and check it yourself and then you might say it is raining.
