Why Don't You Sleep On It?

thefirelane wrote to mention a New Scientist study that indicates your subconscious mind is a better decision maker than you are. From the article: "The research suggests the conscious mind should be trusted only with simple decisions, such as selecting a brand of oven glove. Sleeping on a big decision, such as buying a car or house, is more likely to produce a result people remain happy with than consciously weighing up the pros and cons of the problem, the researchers say. Thinking hard about a complex decision that rests on multiple factors appears to bamboozle the conscious mind so that people only consider a subset of information, which they weight inappropriately, resulting in an unsatisfactory choice. In contrast, the unconscious mind appears able to ponder over all the information and produce a decision that most people remain satisfied with."

      I don't know if it's necessarily working on problems, per-se. However, during REM sleep, your brain is at a very high level of metabolic and electrical activity, and is doing things like reinforcing long term memory. It's possible that this integration process makes for better decision making.

      That said, without seeing the actual research paper, I'd have to say that the results of the study are rather specious. I'm not buying a research metric based on how people judge which "shampoo" is better.

      And, when it comes to the subconcscious, I think I'd have to vote that it would NOT be the best idea to control one's consumer experience solely in that manner. The effects of TV marketing in the USA, and 'mass-consumerism' do not contribute to better buying decisions. I believe that subconscious buying = impulse buying.

      The buying habits of Americans would benefit from change that comes from mindful consideration about what we really need, where things are made, and how we're going to afford things in the long term.

But then I realized in the dream that I was asleep, so saving to a dream drive wouldn't work -- when I woke up again, it would be gone. So the solution was to print it. Somehow, in dream logic, the printout was more persistent.

      The next morning, I knew I had to check the printer for something. Unfortunately, I found nothing there. I couldn't remember why I needed to check, although I felt really let down that there was no print out.

      I gradually reconstructed the dream, and even got back to the solution I had come up with. Turned out to be incorrect, but got me on the right track ...

    This fits in nicely with another finding that seems amazing when you first hear about it, but is obviously true:

    People spend more conscious thinking time on a choice when it doesn't really matter.

    Hard to believe, right? You'd think we would think long and hard about things that matter (in the sense that one or the other of the choices will be far better or worse than the other) and not waste time on choices where the outcome is pretty much the same regardless of what we decided. But that's not, in fact, how we operate.

    If you give people a choice between, say, being paid a dollar or getting hit with a stick, they make up their minds much quicker than if (to choose an example at the other end of the spectrum) you let them pick a candy out of a box of identical chocolates. You can even induce the effect; people will eat potato chips out of a bag one after another without even looking at them, but if you spread the same chips out on the table and ask "which chip do you want to eat next?" so that it becomes something they have to decide they will generally slow to a crawl.

    If they don't know they're going to have to make a choice after their distraction, their subconscious won't do anything special.

    This is just the same old story where if you have a problem, go think about something else & your subconscious will work it out for you. It's nice to see scientific proof for something that I've always considered anecdotal.

    Marketers have known this for years. Marketing departments spend huge amounts of money exploring ways to nudge people into making the 'impulse buy' and trick them into unwise decisions. Grocery stores line their queues with trinkets and small items. Best buy is even worse- forcing people to wind their way through a twisty aisle made of boxes of small, inexpensive items to get to the checkout counter. Once, when shopping for a car, the salesman asked me 'What would it take for you to buy this car today?'. The list goes on... and, it seems to me, we are making worse and less informed decisions as time goes on.

    Trying to find real information on a product is sometimes very difficult. Instead of making better products, companies make a cheaper product and spend a little more on marketing to promote it.

One way or another, most of the people I know seem to be cognizant of the fact that their unconcious is an excellent place to work problems out.

You had to fill each cell with a number from 1 through 8. The challenge was to place the numbers such that no consecutive numbers were adjacent to each other in the horizontal, vertical, or diagonal directions. The guy who showed me the puzzle had supposedly known it for 20 years, but had never solved it. I tried my hand at it quite a bit before bed that night. Finally I just let it go for the moment so I could get some sleep. As I started to drift off, I saw the puzzle in my head. As I watched in my mind, all the numbers dropped into place one by one.

    I popped out of bed, grabbed a piece of paper, and replicated what I had just visualized. Sure enough, it was the solution to the puzzle! My unconcious mind had solved a problem that my concious mind hadn't been able to tackle after hours of trying! After that, I learned to rely more on shoving a problem back into my unconcious, then waiting for a solution to work its way forward. :-)

But no decision was not final until the next day, when the question was reviewed thoroughly in the "cold light of day".

    In this way, a person could get to know the potential business partner or in-law, learn how they do things when their guard was down at least a bit, and find out whether they can get along as people; and get the basic facts and factors of the decision.

    Then, after sleeping on it and 'digesting' the information, they could use their more analytical daytime-brain to go over what they might not have thought of the night before. In the end, one might say that each side of their brain had the chance to contribute to the decision.

  20. Decision making made easy by RealProgrammer · · Score: 3, Interesting

    Well, sort of.

    A complex decision is a whole bunch of trade-offs, profit-and-loss variables. Each variable has a probability associated with it, and they can cascade together. I use a system of "expected value" summations, and it works pretty well.

    For instance, in buying a car there is the price (and the 100% likelihood that you'll have to pay it), a set of features, and a set of unknown costs (maintenance), and a set of emotional value points (prestige, convenience, dependability). Each of the costs has a probability that you'll incur it, and each of the values has a probability that you'll receive it. Some of them are related, and may need to be refactored to make the math work out for you.

    You multiply each of the costs and outcomes (positive and negative) with their value to you (on some scale of your choosing) and their probability of occurring, and sum them all up. That choice gets a score.

    Compare the score from all of the other choices you could make, and your decision is made.

    The nice thing about this system is that by breaking down the fuzzy-factor "value" for each outcome and pairing it with a probability, you see the real cost for each while simultaneously hiding the answer from yourself. Subconciously you will tend to favor the choice you want to make, but be careful that you don't fudge the probabilities.

    As a simple example, consider recreational sky-diving. The value you get from jumping -- a rush, some prestige, and maybe some sex out of it somehow -- compares with a (call it) 99% probability of landing safely and a (call it) 1% probability of landing with a splat.

    For me, I assign a pretty high value to keeping my skin intact. How much would I pay someone not to flatten my skull?

    stay on ground = free + 0 (death from falling) + 0 (fun)
            = 0
    skydiving = -$50 + .01 (death from falling) + .99 (fun)
            = -$50 - 1/100 (very big number) + .99 (small number)
            = (probably something negative, and I have to pay 50 bucks).

    As a side note, you can see that the resultant costs of a decision and the cost to make it happen are just two labels for the same thing. That is, whether something is a cost or benefit is just the sign on the term.
