I found the conclusion of this author, and, presumably, the scientists, to be questionable.

Rather than to praise "the body" for "knowing 40 cards before the brain, which deck was the bad deck", I would submit that no praise is necessary.

We all learn, eventually, to discount failed trials in the experiments of daily survival. We don't quit asking out girls the first 10 times in a row we're shot down. We don't quit fishing the first 10 times we come back empty handed. We don't quit trying to light a fire, the first 10 times the spark from our rock doesn't ignite our dry grass.

We do, eventually, figure out when the game is rigged. When the girls are married, the fish are sleeping, and grass isn't really that dry, we do, eventually, give up. We're not idiots. However, we've learned that the body is not as smart as we are. Too often, it's told us to quit, when, by ignoring it, we've succeeded. The body's responses are the instinctive, reptilian responses of the cortex, while we succeed on this planet by using our mammalian frontal lobe to find less obvious solutions.

So ...

My point is that, the scientists rigged a test, where the reptilian response of our body was the correct one, and then brag about how smart our body is. In this instance, like a stopped clock, it happened to be right. But I'm not trading in my frontal lobe just yet.
