More than anything, what I see on a day-to-day basis is simple lack of reasoning. Whether it be deductive reasoning at figuring out how to do something without having someone personally spend an hour holding your hand or more complex things like troubleshooting or improvisation.

I spend a lot of my time at work improvising on-the-spot solutions to problems after having to troubleshoot said problems. I've seen things that would make your head spin.

Like a technician installing a device that has an adjustable address wheel that goes from 1 to 5. And he's already lost the directions, and we've never installed one like it before. I arrive to help, it's set to address 1 and it isn't working. I change the address to 2, no go, 3, no go, 4, now it works. How hard was this?

I see every day that simple tasks like changing a tire or replacing a fuse just wreck a lot of people's day. So many people just get the "deer in the headlights" look the minute anything out of the ordinary happens.
