I'm not so sure about Ian's application of the Heisenberg principle. Ian
states that trying to observe  (study) a system changes the system. This
does not scale up well from the subatomic. He was talking in the context
of studying the dinos, and I would maintain that a lot of study could be
done WITHOUT changing the system. Hammond's people were observing the island
with satellite derived infrared images; in no way could this ever change
or disturb the system(s) there.

Alot depends on the method of observation and what you're looking for.
For a more modern and relevant example, consider the recent news
stories about companies spying on workers.
