It’s been a few years since my math lectures at university and I don’t remember these two being explained so simple and straightforward (probably because I wasn’t used to the syntax in math at the time) so thanks for that! This’ll definitely stick in my brain for now

It depends how obsessed you are with it. For my wife and me it’s similar: both paychecks go into the same account, but we split off our pocket money into our own accounts accordingly - although I take a bigger sum in this proportion, if I don’t spend it it’ll just be transfered to an account that is play money for vacation, hobbies etc. And that happens idk every quarter or so

In my perspective IQ only has so many consequences, due to the limitations of the method. Nowadays we know to separate different forms of intelligence and also that transferring skills between those forms can have an impact on overall ‘performance’ . That being said, it can be a good indicator for stuff but as you point out, it’s often misused as divider instead of an accelerator.

Although it is reasonable to assume that every marriage ritual in early societies had some kind of ‘blessed be this couple’ aspect, it originated out of civil necessity (structuring inheritance) before the Jesus Club took over and changed the meaning
