Granted, because of my field the students I encounter are science types to begin with, so my experience is limited in that regard - but I know some pretty sharp young people and I'm comfortable thinking that someday they'll be in leadership and decision-making positions.
I will grant you that kids are smarter because of the Internet, but researching skills don’t translate into mechanical skills. Example: Measuring the torque applied to an object.
The three students in the lab were setting up this experiment. They read the directions, set up every thing according to directions, but they could not get a reading of the torque. They called over my TA instructor friend. He took one look and asked them where the cord used in the setup was? Puzzled looks. The TA had to explain the experiment was to measure torque on an item and the cord was necessary to connect the measuring equipment. Stunned looks.
Moral: All read the instructions and followed the setup, except they left out the most critical item to complete the experiment. The problem is not so much brilliance, but lack of attention to detail and mechanical ability.
