Are we smarter than cavemen?Published May 16, 2018
Perhaps we have better tools than cavemen, as we no longer have to concern ourselves with starting a fire or hunting for food, but when it comes to our actions, it is without a doubt that we haven’t evolved much.
Cavemen, as the stories go, had to react quickly in order to eat or to not be eaten. Gone are the days that we need to react so quickly in order to survive.
Cavemen probably practiced, probably at times not willingly, the art of hunting over and over as well as the ability to evade predators. This was built into their natural system of reactions, which made them automatic when it came to acting out these tactics. Think of an NBA player dribbling the ball so much during practice that it becomes automatic for them, regardless of how hard we non-NBA players think it is. This can be compared to the 10,000 hour rule, written about by Malcolm Gladwell in his book, Outliers: The Story of Success, which says that 10,000 hours of practice could make anyone become an expert in a given field. Of course there is opposition to this, but it remains that this amount of deliberate practice holds for fields that do not require much change, like basketball, or being a skilled hunter.
Getting back to our inability to surpass cavemen when it comes to cognitive evolution, I believe it is best described by Daniel Kahneman in his book, Thinking, Fast and Slow. Kahneman discusses System 1 and System 2 processes, where System 1 is responsible for the quick reactions (our immediate responses) and System 2 is responsible for our more mature reactions, after we’ve had time to process the situation and think through it. Cavemen survived with System 1. We no longer have to.
Often, our emotions get the best of us and prevent System 2 responses. I believe Daniel Goleman describes why the best. He is credited with the phrase, ‘amygdala hijack,’ from his book, Emotional Intelligence, which means that the center part of our brain, the amygdala, reacts before the cerebral part of our brain. This was very useful when it came to the stories of cavemen and survival, the automatic actions that often benefit them. But today, when survival isn’t ‘eat or be eaten’ for the overwhelming majority of us, an amygdala hijack often results in us not controlling our emotions.
This happens quite often on Twitter. Simply observing an argument gives someone the ability to see when one party is victim to an amygdala hijack, as they wouldn’t respond that way given time to think. System 2 responses, as Kahneman called them, seem to be few and far between on Twitter, those rare discussions that result in understanding from both parties.
Twitter is a microcosm of the real world. Sure, both parties are behind a computer screen, but their reactions and feelings are very real. If we can’t learn to control our System 1 responses that all too often result in sarcasm and insults, will we ever get past an amygdala hijack and be smarter than the humans who lived tens of thousands of years ago?
