Your Antiquated Mind: The Evolution of Fear

Analyzing and deconstructing fear to rationally subdue or ignore it when appropriate.

Have you ever imagined jumping off a building? How about jumping out a window? As you think about jumping, what height feels comfortable without a significant fear of being injured? How far do you think you could jump before it would kill you?

I’d be sort of okay with jumping from a second story window and think I’d be fine as long as I landed right. When I startled an intruder in my living room, he jumped out through a second story window and almost hit the ground running. Then again, I was holding a gun AND he landed on grass… maybe that’s not the best example.

The fear Nazis out there are fond of making declarations of fearlessness in the face of any danger. Most people roll their eyes at such claims, brushing them off as misguided attempts to display courage. And for the most part, people who claim not to have any fear are just showing off. However, it may be true that some people have relatively low instances of fear. They’re rather rare for one simple reason… The genes of people with no fear get weeded out by evolution.

The rest of us have genes that give us a relatively healthy level of fear. Unfortunately, many of our fears are antiquated. Sure, they may still have some value, but the level of fear we have for various things is not correlated with the things most likely to cause us harm in our modern world.

Most Common Fears

From Forbes.com (in no particular order):

  • Heights
  • Speaking In Public
  • Bugs (especially Spiders, Scorpions, Bees)
  • Water
  • Snakes
  • Bridges
  • Mice
  • Bats
  • Public Transportation
  • Storms
  • Closed Spaces
  • Tunnels
  • Crowds

Heights

Let’s think about heights again. What’s the real fear? There’s a cliched quip about a fear of heights that’s something like, “I’m not afraid of heights, I’m afraid of falling”. This is an attempt to get at the underlying cause, but it can be deconstructed even farther. We’re not really afraid of falling or we’d never learn to walk. The root of the fear is high-speed impact with immovable objects.

Most people would experience some fear responses if perched on the ledge of a tall building. Hitting the ground from a 19 story fall is roughly equivalent to smashing into a solid brick wall while driving 75 mph. Compare that to the impact speed of jumping from the roof of a 2 story building at about 25 mph. To put that in perspective, the highest recorded speed for a human is 29.8 mph. So, while jumping off a building of that height may cause serious injury or death, it is a human scale measurement that our evolutionary ancestors would have been comfortable with.

The important thing is this: We experience a fear of heights because of the implied speed of impact, but we really do fear heights because of the context of height. For the vast majority of people, 75 mph is a comfortable driving speed. The consequences of impact are similar to the fall. However, most of us would keep on driving happily, but back up from a ledge.

This can be examined on an even deeper level by comparing the sensation and reaction of riding in a modern, well-sealed car compared to a motorcycle. Is it really high wind that we’re afraid of? Maybe the higher noise levels in an unsealed environment?

We didn’t experience speed in our evolutionary past. For our tribal ancestors, the only way to achieve high-speeds was to fall from great heights. Unfortunately, this was not an experience one could repeatedly experiment with. There was no way to feel rapid acceleration or deceleration either. Therefore, we never had an opportunity to evolve a rational fear of speed based on speed itself. We instead evolved a fear of ledges and vertical distances.

The Holy Trinity of Fear

Rational fears generally evolved in response to one of thee following three negative forces. Comparing them to the list above does result in a mixture of various combinations. And of course it will vary by person.

  • Death
  • Social Degradation
  • Unpredictability

It’s easy to see why people (and other animals) would involve a fear of things that can kill us. The other two are intuitive from our experiences, but not quite so easy to explain.

The fear of negative social feedback includes layers of avoiding the punishment of violating social rules (including physical punishment and death). It also has reproductive implications as the potential to lower group status increases linearly with the size of the group. Further, the communication of social foibles to those not in attendance increases geometrically with the size of the group. Social status is a huge factor in attracting high value mates so this concern can be amplified. Even the most seasoned speakers and performers talk about being nervous in the initial moments of interacting with a new group.

The unpredictability factor functions as an amplifier of any existing negative potential. Unidentified creatures moving unpredictably messes with our threat analysis systems. Identified threats moving unpredictably amplify our threat analysis systems. Group dynamics also implies an increased level of unpredictability. There are other nuances, but understanding that unpredictability is the root cause of fear is probably going far enough.

Don’t Be a Crazy Person (WARNING: This may be a a little too close to self-development pap)

Crazy people are dominated by the disconnect between their behaviors in relation to inputs. In this sense, our antiquated minds have the potential to make us all crazy within the modern context. We may react strongly to things that were persistent threats to our ancestors, but are no longer threats today. Standing against a glass wall looking down 100 stories may induce a fear response (or vertigo) despite the relative safety. Driving at high speeds may feel perfectly safe despite traffic fatality statistics being much more serious than accidentally falling out of your apartment statistics.

I’m not going to analyze each fear in its modern context for you. But for every fear you know you have a tendency to experience and every fear you experience in the future, thinking about whether or not your response is rational in modern times is worthwhile.

Other People Are Crazy

This is also extremely useful in examining fears implied or communicated by others. Fear spreads easily. Fear is so well known to cause reactions in people AND so well studied, that fear easy for others to employ it as a method of applying stultifying control.

Is it rational for a mother to fear terrorists are going to harm her child in rural South Dakota?

It’s also useful to examine the converse.

Is it rational for an employee in a company to feel job security? Is the wall of information between company owners and employees eerily soothing?

Some people let fear completely dominate their lives. Others let fear impact them in more subtle ways. Since our brains are flawed by effective anachronism, it makes sense to bend the rules of fear to our advantage.
