They literally don’t teach it at school and I’m pretty sure my grandpa couldn’t tell the difference either so quite literally nobody taught me until I got a screwdriver kit that had both PH and PZ.
Even worse is JIS, where it seems that its explicit and singular goal was to make a screw that would be instantly obliterated the moment a Phillips driver touched it. Fun fact, JIS drivers work far better on Phillips than Phillips drivers do, and I’ve yet to strip one since using JIS drivers almost exclusively
I think a lot of people who strip screws do so because no one told them that Phillips and Posidriv are different and incompatible

I learned about JIS this year when I got my first motorcycle. Honestly maddening how similar they look.
Screws were stripped into fucking circles by the person who tried to fuck with one part before me.
I’ve not tried to use a JIS screwdriver on a Philips head, but thanks for the tip!
Is that what the PZ means, Posidriv?
It’s spelled with a z (“Pozidriv”), hence this short form.
