Uncertainty

Some researchers at Edinburgh University have just published a report about how easy it is to buy prescription-only medicines online. They visited sites which they found via Google and Yahoo but they did not take the final step of actually buying the drugs because they felt that would not be ethical. So they were just counting sites which offered drugs.

At the start of this year researchers at Berkeley and San Diego were doing a study into how profitable spamming could be. They set up a fake online pharmacy which was just like the real thing, offering prescription-only drugs. They counted how many people visited the site and added drugs to their basket. The only point at which the customers discovered that it was not actually working was when they submitted their credit-card details, at which point they got an error page.

So, the Edinburgh researchers probably included the Berkeley researchers in their study, and vice versa, unless they warned each other, which seems unlikely. It’s like a collaborative version of Heisenberg’s Uncertainty Principle – Whenever you try to measure something by doing anything on the web you are probably affecting someone else’s measurements at the same time.
