I like to break down reality into different layers. There’s physical reality, biological reality, social reality, and emotional reality.
“Physical reality” includes not just abstract theories about physics but also our embodied intuitions of how the physical world works, e.g. that I can’t walk through a wall, travel backwards in time, or move clouds with my mind. These are assumptions I need not test repeatedly to see whether they’re still true
It’s safe to assume that you are going to age and die and that you need food and water to survive. But the parameters can be tuned quite a bit—some people get by with extreme fasting or very little sleep, and plenty of people think we’ll eventually cure aging, cancer, and other biological problems.
Social and emotional reality are the most malleable, and I think these are the areas where people take too many things for granted.
Remember that all of our rules, laws, and social conventions are made up. Even the literal concept of a corridor is something that a guy came up with in 1597.
it’s not just that there are exceptions to the pattern, it’s that the pattern applies to people in the past, and social reality is always changing.
In particular, social reality is changing more quickly than ever because of the internet. Most people still don’t appreciate how much power the internet gives us: for accessing information, for sharing ideas, for connecting with people who share your interests and goals.
Examples of social realities that people take for granted but which are subject to change (and have already changed a lot):
I need to go to college in order to have a well-paying career
I need to pay for a course in order to learn about X
The broadest form of this is “I need permission from someone with authority in order to do what I want to do”. I guess we can be forgiven for believing this, since this is what elementary school looked like for many of us: you had to get a hall pass in order to leave the classroom to drink water. So of course you’ll believe that “getting permission” is the default mode of navigating the world.
