The Observer Effect, from Jeff Watson
June 21, 2011 |
I was reading about the famous double slit experiment and then thinking about the Heisenberg uncertainty principle, the math, and the observer effect. I wonder what types(if any) of market implications could be attributed to the observer effect.
Ken Drees writes:
Interesting. I was contemplating this more than a few weeks ago too, but let it drop. It made me think of Schrodinger's Cat:
Schrödinger's cat is a thought experiment, usually described as a paradox, that Austrian physicist Erwin Schrödinger devised in 1935. It illustrates what he saw as the problem of the Copenhagen interpretation of quantum mechanics applied to everyday objects. The thought experiment presents a cat that might be alive or dead, depending on an earlier random event. In the course of developing this experiment, he coined the term Verschränkung (entanglement).
I was considering how a trade is alive and real only when one puts it on or opens the box and everything else is meaningless– the counting, the theory, the expected outcome– all meaningless unless you commit and then make it real and apart of consciousness, reality, an entity.
Michael Cohn adds:
Schrodinger's kitten's also interesting as a thought experiment across space and time. What I recently learned about the uncertainty principle was that there is a different way to think about it. I always thought about it in terms of how the observer may be creating the uncertainty in measuring both mass and acceleration with the instruments. What I now understand is because of quantum uncertainty these particles actually don't really know exactly where they precisely are at a given point in time beyond a prob distribution so if they don't know where they are I certainly can't help them as much as I would likes to be able to do so…
Jim Sogi comments:
2 closing related issues:
There's the insidious cursor and key watcher viruses.
Another related aspect is the inadvisable practice of putting your cursor over the execute button onscreen and having it execute without having touched the mouse, or accidentally touching the mouse or keyboard at the wrong time triggering the trade. Been there, done that.
There is also the issue of order field depth, which is a form of "disclosed" watching, and other order related manipulation issues perhaps posing, perhaps honest bid, perhaps flow bashing or bandwidth hogging, flashing. Lack surely can speak to many of these techniques he sees in individual stocks.
Russ Sears adds:
If risk is defined as what is not known in the future that if it happens would hurt you, than imagination of what could happen causes you to avoid and prevent that perception.
Done to extremes this creates new risks from the over abundance of care and lack of focus on any other risks even to the point of altering the minds ability to cope. Think interest rate duration management and the creation of the tranches in the securitization process and modeling of those securities. Done in mass this creates bubbles, hysteria, or pop-stars. ( I believe this is the "Lady Gaga" "Apple" link. It is not mysticism but the creation of popular mystic.)
Much of psychology is the study of how unrealistic risk perception creates a difficult life and alters their reality for the fearful and anxious. Why should the markets be immune?
Ken Drees comments:
Lady Gaga is to Apple as Amy Winehouse is to Rimm.
