Do we really need proof for common sense?

This is STUPID!

why do we need to have such an experiment?
conclusion: when u watch-and-learn, u really learn something.

of coz u do...that's what u call learn through imitation..baby does that, kids does that and even adults do it, its universal and i dare say its encoded in the genes that this is the BASIC learning ability long recognised.

if science is able to conduct such a study to proof the already proven and obvious i don't think i will ever have any problems with a career as a researcher!
