Water - all it's cracked up to be!

In 1966, Dr. Paul Irena did a study at Johns Hopkins where one class of math students drank nothing but water for a week, while another math class also drank water, but was paid $1 for every glass they drank. A third group was not given advice on what to drink, but was paid anyway. While this was going on, the test scores were being closely monitored in all three groups to see if hydration or monetary compensation had any influence on test scores. The controversial results were that water seemed to improve test scores independent of money. Big business interests seized upon this result as a way to justify not giving raises to improve productivity, but rather "watering down" their staffs.
In 1967, the study was revealed to be a hoax by an overhydrated grad student. Outraged employees demanded higher wages. Water coolers were smashed. A class action suit managed to hush up the whole situation.

What conclusions can we draw from this unhappy situation?

Clearly, we need to be hydrated, but also not to be exploited in the workplace. everyone should have frequent water breaks. But the exact experiment has not been retried due to the sensitive nature of the suit.
