10 Ways Your Brain Makes you Dumb

10 Ways Your Brain Makes you Dumb

The human brain is an impressive yet bewildering thing. Although it only weighs about three pounds, this organ processes information amazingly fast. The slowest speed is 260 mph. That’s the same speed as the fastest car on Earth! Our highly evolved brains are what differentiate us from other animals. However, as much as our brains help us function, we’re still susceptible to being tricked.

Here are 10 ways our brains make us surprisingly “dumb.”

1. You Filter Out More Information Than You Realize

We all want to think that we are aware of everything, all the time. However, the truth of the matter is that we are not. Our brains use about 20-25% of our body’s energy, so it’s important that our brains act as efficiently as possible. In order to do this, the brain filters out a lot of “noise” in our environment, focusing our attention on the things we deem important by using the reticular activating system (RAS).

Have you ever considered buying a particular car and then noticed it everywhere? It’s not that everyone bought that same exact car the same day, your RAS was in action and was focusing your attention on that specific car. Since your brain was focused on the new car purchase, your RAS took note of it, making you even more aware of that car in your environment.

The RAS is an essential network in the brain that helps us parse through the massive amount of information we are exposed to everyday. Since it’s such a great tool, it’s surprising to realize that you’re filtering out a lot of information.

2. Your Brain Can Be Primed

Do you ever go shopping, flip over a tag, and find a great deal you can’t resist? The shirt you’re considering buying used to be $200, now it’s only $20 — it’s a no brainer! Is it really a good deal, or is your mind primed to think so because you saw the giant “x” over the original price? This shows how an initial stimuli can have huge affects on our subsequent decisions or behaviors.

In an interesting study, subjects were primed with words related to elderly people. After hearing those words, the subjects were found to walk slower when leaving the experiment compared to the control group who wasn’t primed. The same study showed that when subjects were primed with words related to rudeness, they were more likely to interrupt the experimenter.

3. Too Many Options Lead To Indecision

You may think that having a variety of options is a great thing — it’s not. Although it may seem advantageous to have a variety of options to make the best decision, your mind actually gets overwhelmed, thus decreasing your odds of actually making a choice.

Have you ever been browsing Netflix at night and just felt totally paralyzed? We’ve all been there, flipping through the endless choices presented to you. That’s the paradox of choice in action.

A fascinating experiment in a grocery store examined a stand with 24 different varieties of jams for shoppers to test and buy. Those who sampled got a $1 coupon towards any purchase. The 24 jam display got a lot of interest as people wanted to taste-test different flavors. A similar table was set up the next day, but this time it only had six jams to try. Although the smaller table wasn’t as popular, when it came to buying the jam, people who saw the smaller display were ten times more likely to purchase.

Why is that? Having too many options can lead to indecision or inaction. Even worse, when we face too many options we feel even less satisfied with the choice we made.

4.  You View Your “Future Self” As A Stranger

Do you ever pig out on a Friday, then justify eating your way through your weekend because on Monday you’re going to start that new diet? We tend to think of our future selves as totally different people, causing us to weaken the connection of the pain or sacrifice that our “future self” will have to go through just to burn off those weekend calories.

Numerous studies have shown that our brain thinks of our future selves as entirely different people. So much so, we may as well be thinking of a celebrity! In a study conducted by Hershfield and his colleagues, when imagining their future selves a subject’s neural activity was similar to when they described celebrities like Matt Damon! The experimenters took this a step further, asking their subjects to either look at themselves in the mirror or look at a photo of their future selves (by way of digitally making their face look older). Afterwards, they were asked how they’d spend $1,000, those exposed to their “older self” said they’d put twice as much money into a retirement account compared to those who saw their current self in the mirror.

5. You Grow Attached To Objects You Touch More Often

Every try spring cleaning but get stuck holding onto things with sentimental value because you just can’t fathom throwing them away? Research has shown that the more often you touch something or spend time with it, the more value you place on it.

This study shows that the more time someone spends with an object the more “pre-ownership attachment” they will associate with it. They figured this out by allowing subjects to examine and touch basic coffee cups prior to being auctioned. When they were auctioned off, those who spent more time examining the cup were more likely to overbid on the coffee cup. That’s why retailers want you to try clothes on, take a test drive, and eat taste-testers.

6. Lack Of Willpower Leads To Bad Decisions

Willpower is like a gas tank. It starts off full but gets depleted throughout the day, by either making decisions or exercising self control. What happens when that gas tank is running low? Well, you probably guessed it, it’s way harder to exercise self-control and make good decisions.

In a remarkable study, researchers studied over 1,000 court rulings regarding whether or not the judge granted a criminal parole. They found that the number one factor in whether the criminal would get parole or not was based on the time of day… not their crime or their record — the time of day!

They figured out that the earlier in the day the trial took place, the better chances the criminal had at getting parole. It turns out that the judges suffered from “decision fatigue” towards the end of the day. The easy decision to make after being fatigued was to simply say “no.”

7. You Don’t Panic When You Should

Have you ever felt a minor earthquake in the middle of the night? You may wake up alarmed for a few seconds, but then you roll over and fall back asleep. That’s the normalcy bias at play. This bias occurs when there’s a disaster going on and instead of getting into “fight or flight” mode you convince yourself that everything is totally normal, leading to inaction.

This bias leads to a lot of unnecessary deaths and injuries such as Hurricane Katrina where residents never thought the levees would break. When they actually did, they were stuck at home, faring the worst.

Scientific hypotheses suggest this occurs because it takes our brains 8-10 seconds to process information. Adding stress to the equation slows this down even more.

8. You Make Bad Assumptions

The “availability heuristic” is a mental shortcut we take. It’s when we believe something is common place if we have an example to reference or are already familiar with it. For example, if we have a lot of friends with iPhones, we assume that everyone has iPhones!

An experiment from the University of Zurich showed that people who had been affected by flooding (or knew someone who was) were more likely to perceive higher risk about flooding probabilities in their neighborhood compared to those who never had such experiences. Those affected by flooding had memories “available” to them to reference, causing them to perceive a much higher risk than those who never experienced it, even though the probabilities were exactly the same.

9. You Use Emotions In Making Decisions

Even though we’d all like to trick ourselves into thinking we make decisions based on black and white logic, research shows otherwise.

Thomas Damasio, a University of Iowa neurologist, has shown that decision-making happens in more than one part of your brain. Prior to his research, most neuroscientists believed that decision-making only occurred in the rational and most highly evolved part of our brains, the prefrontal cortex.

Although that is the case, there’s another interesting part of the brain at work: the limbic system. This area is a much older part of our brain responsible for emotions. It’s the part of our brain where we make value judgments regarding experiences and memories. These various parts of the brain work together to make decisions.

10. Your Memories Are Wrong

Do you and a friend ever recall a memory you shared, but argue over the details? When you guys first heard about 9/11 it was at your house… or was it at school… or the gym?

You’re 100% sure he was at your house, but he’s saying it was at school, and you are both sure of it. It turns out that the more emotional a memory is, the more confident we are around recalling that story accurately.

In 1986, the Challenger space shuttle exploded. It was a memorable day for many Americans. The next day, Ulric Neisser, a Professor at Emory, handed out a questionnaire to his students asking them to reflect on where they were and who they were with, as well as other details at the time of hearing about the Challenger explosion.

Two and a half years later, Professor Neisser handed out the same questionnaire to the same group of students. The average accuracy of these memories was a measly three out of seven. However, what was even more fascinating is that when asked about how “confident” they were in recollecting their memory the average rating was a whopping 4.17 out of five!

We tend to be confident about an event and the details surrounding it even though we are actually way off. This is because we tend to have “tunnel vision” on the major event and the minor details associated with the memory tend to be forgotten.

Productivity Boost: How to start your day at 5:00 AM

Productivity Boost: How to start your day at 5:00 AM

I have been an early-riser for over a year now. Monday through Friday I wake up at 5:00 AM without hitting the snooze button even once. I never take naps and rarely feel tired throughout the day. The following is my advice on how to start your day (everyday) at 5:00 AM.The idea of waking up early and starting the day at or before the sunrise is the desire of many people. Many highly successful people attribute their success, at least in part, to rising early. Early-risers have more productive mornings, get more done, and report less stress on average than “late-risers.” However, for the unaccustomed, the task of waking up at 5:00 AM can seem extremely daunting. This article will present five tips about how to physically wake up at 5:00 AM and how to get yourself mentally ready to have a productive day.

Many people simply “can’t” get up early because they are stuck in a routine. Whether this is getting to bed unnecessarily late, snoozing repetitively, or waiting until the absolute last possible moment before getting out of bed, “sleeping in” can easily consume your entire morning. The following tips will let you break the “sleeping in” routine.

Relocate your alarm clock.

Having an alarm clock too close to your bed is the number one reason people simply cannot get up in the morning. If your alarm clock is within arms reach of your bed, or if you can turn your alarm clock off without getting out of bed, you are creating an unnecessarily difficult situation for yourself. Before I became an early-riser, there were many times that I would turn off my alarm without even waking up enough to remember turning it off. I recommend moving your alarm clock far enough away from your bed that you have to get completely out of bed to turn it off. I keep my alarm clock in the bathroom. This may not be possible for all living arrangements, however, I use my cellphone as an alarm clock and putting it in the bathroom makes perfect sense. In order to turn off my alarm I have to get completely out of bed, and since going to the restroom and taking a shower are the first two things I do everyday, keeping the alarm clock in the bathroom streamlines the start of my morning.

Scrap the snooze.

The snooze feature on all modern alarm clocks serves absolutely no constructive purpose. Don’t even try the “it helps me slowly wake up” lie. I recommend buying an alarm that does not have a snooze button. If you can’t find an alarm without a snooze button, never read the instructions so you will never know how long your snooze button lasts. Not knowing whether it waits 10 minutes or 60 minutes should be enough of a deterrent to get you to stop using it.

Change up your buzzer

If you use the same buzzer day in and day out, you begin to develop a tolerance to the sound. The alarm clock will slowly become less effective at waking you up over time. Most newer alarm clocks will let you set a different buzzer tone for the different days of the week. If you change your buzzer frequently, you will have an easier time waking up.

Make a puzzle

If you absolutely cannot wake up without repetitive snoozing, try making a puzzle for yourself. It doesn’t take rocket science to understand that the longer your alarm is going off, the more awake you will become. Try making your alarm very difficult to turn off by putting it under the sink, putting it under the bed, or better yet, by forcing yourself to complete a puzzle to turn it off. Try putting your alarm into a combination-locked box and make yourself put in the combination in order to turn off the alarm — it’s annoying, but extremely effective!

Get into a routine

Getting up at 5:00 AM is much easier if you are doing it Monday through Friday rather than sporadically during the week. I recommend setting an alarm once that repeats everyday. Also, going to bed at about the same time every night is an important factor to having a productive morning. Learn how much sleep you need to get in order to not feel exhausted the following day. Some people can get by on 4-6 hours while most need 7-8.

Have a reason

Make sure you have a specific reason to get up in the morning. Getting up at 5:00 AM just for the heck of it is a lot more difficult than if you are getting up early to plan your day, pay bills, go for a jog, get an early start on work, etc. I recommend finding something you want to do for yourself in the morning. It will be a lot easier to get up if you are guaranteed to do something fun for yourself — compare this to going on vacation. You probably have no problem waking up very early on vacation or during holidays. My goal every morning is to bring that excitement to the day by doing something fun for myself.

As I previously mentioned, I have been using these tips for a very long time. Joining the world of early-risers has been a great decision. I feel less stressed, I get more done, and I feel happier than I did when I was a late-riser. If you follow these tips you can become an early-riser, too. Do you have any tips that I didn’t mention? What works best for you? Let us know in the comments.
