This ties into the penguin theory of learning. Whenever one finds themselves in something like initial new training, it applies. The new hire's brain is like a chunk of ice, just floating there. The penguins are ALL the information, just swimming around and trying to hop on the ice chunk. The ice chunk (brain) can only handle so many penguins (information). Once it gets full, penguins start falling off back into the water, it can only handle so many penguins. Maybe if the penguin is good/important enough he'll get back on the ice chunk. Hopefully he doesn't fall off, get eaten by a polar bear, and sh1t into the ocean and never to be seen again.

The guys that try to memorize useless information, or try to throw it out in study sessions are coming dangerously close to having all the wrong penguins on the ice chunk. As well the possible collateral effect of putting too many penguins on their fellow classmates ice chunks.

It's all about managing the penguins.
