A classic example is probably around things that are considered as ‘common sense’. For example, you might know, either from previous experience or from what you’ve read, that people on the London Underground (tube/train stations) would stand on the right of the escalator and allow other people to walk up on the left side.
(we won’t get into the detail on how this might be harmful to the mechanism of the escalator itself, as that’s a totally different story)
But a tourist who came from a different country may not be aware of the stand-right-walk-left rule, and might be confused when they first see the 'rule’ happening. So you might get tourists doing the complete opposite like standing on the left and creating a chaos or disruption to traffic.
You might be thinking, meh, that’s nothing. But, in real life, once you’ve learnt something, it can be hard for you to understand how it is for new learners. The more knowledgeable you are in a certain topic, the harder it may be for you to connect and relate to newbies.
In my own life, I see this happening a lot since I got married to Aiman. I’ve always done things in a certain way, and arrange my clothes in a certain way. When I got married and we moved in to my parents’ house, I’ve assumed that he would know where things are or understand when I told him to 'check the laundry’, when I’ve never actually told him where the laundry are usually hung to dry.
(this was an actual conversation we had on Friday, fyi)
Being aware of the Curse of Knowledge cognitive bias requires me to be more aware of the knowledge and experience that I have and learn to be more patient when dealing with other people. I have to realize and understand that people might not know what I know, and therefore I need to stop assuming and start explaining myself better. This can help avoid any unnecessary stress or problems due to misunderstanding or confusion.
