Studies Show the Value of Not Overthinking

WSJdpatton writes "Fishing in the stream of consciousness, researchers now can detect our intentions and predict our choices before we are aware of them ourselves. The brain, they have found, appears to make up its mind 10 seconds before we become conscious of a decision — an eternity at the speed of thought. Their findings challenge conventional notions of choice, writes WSJ's Robert Lee Hotz."

Not a threat to sentience...

[Fustican]

The test the article discusses seems rather arbitrary -- letters streaming across a screen, and you decide when to press a button. Perhaps what they detected was the buildup of boredom? Analyzing complex inputs and reasoning to a decision is a far more complex thing. In any case, I'm not convinced that all my decisions are predetermined by fate or particle physics.

From personal experience this is a very likely to be the case. In college when I participated in random psych experiments, as required by the class, I would notice gaping errors in testing that completely tainted the results.

Example: I signed up for 1/2 hour experiment, I get there and the tell me it's an hour long and I will be analyzing erotic art with a female student. They emphasized that, which I thought was pretty unnecessary and odd, and there was no girl in the waiting room with me before the experiment. Anyway I put all this together and figured it was just a fake-out and that I wasn't going to be doing any actual analysis. Sure enough the researcher comes in and says "ok she will be coming in soon, rearrange the tables and chairs how you like." Uhuh, yeah this isn't contrived. Anyway I intentionally put the chairs right next to each other just to be contrary, because at this point it was beyond ridiculous to keep playing along. Anyway then they came in, took pictures of the chairs, and told me it was all a trick to see how I would position them - WHO WOULD HAVE GUESSED?!

Anyway, almost all the experiments I did had some kind of fatal flaw in it. I had another one - similar to what you're talking about - in which I was told to look at various numerical matrices which were then taken away and I was asked to answer 5 timed-questions about it. If I finished the question block a new matrix showed up, but the questions were complicated enough that I often could not even finish them before the timer ran out. This went on for ONE HOUR. After 10 minutes I was mentally exhausted and just putting in whatever for answers to get through all my blocks as fast as possible - I had totally stopped caring. At this point I also assumed that this must be the actual experiment - to gauge exhaustion. But no, when the researcher came in he thanked me and that's it - if it had been another experiment he would have had to tell me.

So unless we see the entire experimental procedure written down, it's impossible to determine if their findings were legitimately obtained. Unlike other disciplines, psych/neuro results are particular susceptible to improper experimental procedure. Like you say, they could have just detected boredom.

Re:10 seconds.

The major experiment uses a flawed definition of "decision". If I were the subject it might take me several seconds of unconscious cogitation to formulate a plan: when the next letter flashes I will press the left button, for example. The real decision is made below the level of consciousness, so the letter recorded is the one shown when the action is started, not the one shown when the decision-making process is started.

This is similar to driving a car. When you are driving to a well-known destination, when do you "decide" to turn the steering wheel to enter the parking lot? At the conscious level you decide when you see the driveway, and that there is no traffic in your way. The real decision, however, is made as part of the plan to drive to your destination, which may have been decided minutes or hours earlier.

The experiment is really about the unconscious part of the decision-making process. That is interesting, but it has nothing to do with free will, since our unconscious is as much a part of us as our conscious.

I used to do the same thing.

This study doesn't bring anything new to the table - we've known for a LOOOONG time that what we perceive as "consciousness" is really more akin to a "ghost in the machine."

What is important, however, is that, despite all this, we can actually, with enough thought, make decisions based on logic, as opposed to "feelings" or "what we think is reasonable."

Most of what we do, we do on "autopilot", and our consciousness re-orders the stream of events so that we believe we "decided" to do what we did. Classic example - think of any time when you jammed on the brakes because of someone who rushed in front of the car ... and think back, and you'll realize that you already had braked before you even were aware of the person, because even the half-second lag between perception and stepping on the brake pedal would have been too long.

Your foot is on the brake well before you're aware that the person is there. Otherwise, they'd be road pizza.

It's possible to completely bypass any "consciousness".

One of the earliest reports was about a guy whose skull was cleaved open with an ice axe. They shoved his brains back in, and he "recovered." He would get up, wash, get dressed, go to work, etc. --- but there was "nobody home". All identity had disappeared. He was just an automaton.

Conscious decision-making, or even awareness, isn't necessary for most activities once they're learned.
