Let’s assume for a moment that I were going to tell you a story – a story that might happen on a television drama.
I might even start out with the cliche, “Once upon a time …”
Then I launch into the story. It’s not a science fiction story, and it requires you to engage no extraordinary belief systems. However the story isn’t exactly like daily life. We know this to be true due to the fact that if television were just like daily life, we wouldn’t watch. Thus, television must be more exciting than daily life.
Off of the top of my head, I’m thinking of an episode of Desperate Housewives that I saw somewhat recently. One of the characters killed a man in her living room, but there was soon — like very soon — to be a part in that living room.
They had to dispose of the body.
Now I’m going to go out on a limb and suppose that you’ve never found yourself in such a situation. Nor, I’m guessing, have any of your friends or family told you a similar story that actually happened to them.
So we’re in new territory here. We’re weaving a tale that is completely outside of your comfort zone and beyond your realm of personal knowledge.
Despite this foreignness, a decade of research in our lab shows that you can make snap-second judgments about the plausibility of events as they unfold.
If, for instance, we were to lean the body against the wall and put a lampshade on his head to pretend he is a lamp during the party, you would quite rightly say, “That would never happen!
My question is this: where does that come from? That is, how you decide what is implausible in the world of the unlikely?
Yet hundreds — perhaps more than 1,000 by now — of participants in our lab show that they make these decisions easily, quickly, and consistently.
The same is true to things highly likely to happen. That is, if the story were to have continued that the women stuffed the corpse into a spare bedroom, you likely would have surmised that this could have happened.
If either case, you would have made the decision quite quickly. Our data show, however, that you would have made the decision about the implausible even slightly more quickly.
For someone interested in the brain, however, this presents a challenge.
How did you actually make that decision?
From the standpoint of what’s in the brain, they are fundamentally different processes. We can argue that for the highly likely scenario, you can drawn upon actual experiences. That is, there are actually memories stored in the network of your brain that suggest that this could happen.
Yet for the implausible case, almost by definition, such memories cannot reside in the brain.
Yet you make the decision equally as quickly — perhaps even faster.
How?
We’ve tried many methods to infuse the decisions with cognitive roadblocks to make it more difficult, but precious little light has been shed.
These cognitive roadblocks can be thought of as slow-motion video, where we slow down the process to get a better look. Still no clear pattern emerges.
Even more interesting are the cases where the next event in the story might or might not happen. These do slow people down, but when we force them to decide under time pressure, they seem to be able to speed things up while coming to the same conclusion.
We are not totally lost here. We have some insight, yet these hypotheses become much more difficult to test. We’re lining up two new studies as we speak to delve once again into the process of reality in an attempt to force the brain to reveal its secrets.
I’ll keep you posted in this space. Experience tells me that we’ll learn a little bit while stumbling upon new questions that had not yet occurred.
The human mind remains the most complicated object in the known universe, and its recursive hold on my imagination is as firm as it ever was.
