Thankyou Brett!! While I was reading your link I thought of how squirrels react to being observed by humans. They are intelligent enough to have a "reaction" to being observed. They "wait" to see what you are intending to do. As an observer, I don't have any malice toward the squirrel, only a curiosity.
Likewise, there may actually be a primitive level of intelligence in the particle/wave entity involved. It would naturally be REACTIVE in nature. Stop and wait is what the squirrel will do. I have seen less reaction in insects, such as bees and ants. The squirrel has an advantage over the insect; more brain power.
Take that to the bank of natural behaviors in the wild.
