To be honest I don’t think intelligence can be boiled down to a single number. Like somebody or something can have a slow processing speed but can do a lot of different things, versus something or someone that is incredibly fast but limited in it’s usage. To some extent this actually happens inside human minds with things like system 1 vs system 2 in psychology having different roles within the brain/mind of a human and being suited to different things (flexible but slow and single tasking vs dumb but fast and parralel in this case).
Also I am considered by my society to have a mental disability. So regardless of how far right of this distribution I might be there are still things I don’t understand that more average people can. You could argue that those things are only domain-specific forms of intelligence but I don’t know if that’s actually true or not. There are too many variables and anomalies we don’t understand.
