Didn’t happen like that to me at all, but that might have to do with from where you’re coming when getting introduced to it. If your expectations are that it’s more like astrology and less like astronomy then I can see someone going “Hey, there is really something to this”.
For me it was more like going from walking to riding a bike to driving a car. You know each will get you there faster; but that doesn’t come as a surprise. Plus, it’s not like a magic pill… you yourself actually have to put effort into it… just like learning the alphabet to be able to read and write.
Maybe that’s also something different. I never considered people without the same skill set peers, so I only compared my performance to people I met at competitions. To go with the above image, of course I’m faster on my bike than people that don’t have one and have to walk. However, that does not mean you’ll win the Tour de France any time soon.
I actually ended up writing an app that is a tutorial to teach calendar calculation (weekday for a date) because a lot of people do see it like a magic trick or they…
It’s unfortunate that not even the basics are taught in school, which in turn would make the whole thing more mainstream (less of a magic show). It wouldn’t even matter if the teachers did a good job at it or not… just like with foreign langue classes, not everyone will come out speaking on a native level, but they’ll know the basics at least.
