Quantum Theory May Explain Wishful Thinking
explosivejared writes "Humans don't always make the most rational decisions. As studies have shown, even when logic and reasoning point in one direction, sometimes we chose the opposite route, motivated by personal bias or simply 'wishful thinking.' This paradoxical human behavior has resisted explanation by classical decision theory for over a decade. But now, scientists have shown that a quantum probability model can provide a simple explanation for human decision-making — and may eventually help explain the success of human cognition overall."
The same mathematical model does not necessarily mean that thought processes are driven by anything quantum mechanical. Quantum theory uses probability models as do psychological models. They are defined by probability theory and not the other way round. i.e. quantum theory uses models that existed before the discretization of energy was even considered.
Or is that just wishful thinking?
The musings of just another geek and his junk.
which is why I make sure every cat I put in a box has been killed beforehand. Suck on that, Schrodinger.
I'm not sure you're looking at this the right way. The abstract does not suppose that this phenomenon results from a quantum physics effect, though I don't know if the research does. Rather, the abstract and the linked article are applying the mathematical models behind quantum theory to problems in cognition. The brain could very well compute these results using classical physics.
I have seen the future, and it is inconvenient.
It's all well and good to use the mathematical techniques of quantum mechanics in other fields but the math by itself is not quantum theory. I get really annoyed with the "Ohhh something weird and mysterious we don't understand it must be because of QM" nonsense. Hello, decoherence anyone? Outside of carefully prepared states, large collections of particles behave classically. You know, that's why we discovered classical physics first.
In other news: a recent study by the American Wave Mechanics Society suggests wishful thinking may explain quantum mechanics.
I'm sure I'm not the first to think of this, but I wonder if wishful thinking is just a way of implementing a particular strategy for survivial. What I suggest could be applied to running a business or living in a Darwinian world.
There are a couple of ways to go about survival in a highly competitive enviornment.
The most straightforward is to be better than everybody else at one or more things. If your competitors run at 3-4mph and you can run at 5mph then you're going to be the one that catches the gazalle and has dinner. The problem with this approach is that EVERYBODY is trying to catch that gazelle and EVERYBODY is out on the track every morning trying to run a little faster. If you succeed at all it will only be by a little bit, but a little bit is enough, so I think this is the predominant method of survival.
The other approach is to just try to do something completely differently. Most likely you'll fail and starve and your genes won't be passed on (directly - though your cousin might pass them on), but just maybe you'll succeed. If you do succeed there is a good chance that it won't be just by an incremental margin.
So, if I were designing an ultimate survivor species, I'd have it do a grinding incremental evolution (approach #1) most of the time. However, I'd also have members of the species occassionally take huge risks for a possible huge reward. As long as families are big enough and these risks aren't frequent then even if the odd member of the family dies the genes that convey these tendencies will still be passed on. If a family member gets lucky then it will be at the top of the food chain for generations.
Perhaps wishful thinking is just an artifact of the brain that we call "wishful thinking" when things go wrong, and "creativity" or "innovation" when that crazy idea that everybody knows won't work actually does work?
