7 Stupid Thinking Errors You Probably Make

7 Stupid Thinking Errors You Probably Make
The brain isn’t a flawless piece of machinery. Although it is powerful and comes in an easy to carry container, it has it’s weaknesses. A field in psychology which studies these errors, known as biases. Although you can’t upgrade your mental hardware, noticing these biases can clue you into possible mistakes.

How Bias Hurts You

If you were in a canoe, you’d probably want to know about any holes in the boat before you start paddling. Biases can be holes in your reasoning abilities and they can impair your decision making.

Simply noticing these holes isn’t enough; a canoe will fill with water whether you are aware of a hole or not. But by being aware of the holes you can devise methods to patch them up. The entire domain of the scientific method has largely been an effort to overcome the natural inclination towards bias in reasoning.

Biases hurt you in a number of areas:

  • Decision making. A number of biases can distort decision making. The confirmation bias can lead you to discount information that opposes existing theories. Anchoring can throw off negotiations by forcing you to sit around an arbitrary value.
  • Problem solving. Biases can impede your creativity when solving problems. A framing bias can cause you to look at a problem too narrowly. And the illusion of control can cause you to overestimate the amount your actions influence results.
  • Learning. Thinking errors also impact how you learn. The Von Restorff effect can cause you to overemphasize some information compared to the whole. Clustering illusions can also trick you into thinking you’ve learned more than you actually have.

Here are some common thinking errors:

1) Confirmation Bias

The confirmation bias is a tendency to seek information to prove, rather than disprove our theories. The problem arises because often, one piece of false evidence can completely invalidate the otherwise supporting factors.

Consider a study conducted by Peter Cathcart Wason. In the study, Wason showed participants a triplet of numbers (2, 4, 6) and asked them to guess the rule for which the pattern followed. From that, participants could offer test triplets to see if their rule held.

From this starting point, most participants picked specific rules such as “goes up by 2“ or “1x, 2x, 3x.” By only guessing triplets that fit their rule, they didn’t realize the actual rule was “any three ascending numbers.” A simple test triplet of “3, 15, 317“ would have invalidated their theories.

2) Hindsight Bias

Known more commonly under “hindsight is 20/20“ this bias causes people to see past results as appearing more probable than they did initially. This was demonstrated in a study by Paul Lazarsfeld in which he gave participants statements that seemed like common sense. In reality, the opposite of the statements was true.

3) Clustering Illusion

This is the tendency to see patterns where none actually exist. A study conducted by Thomas Gilovich, showed people were easily misled to think patterns existed in random sequences. Although this may be a necessary by product of our ability to detect patterns, it can create problems.

The clustering illusion can result in superstitions and falling for pseudoscience when patterns seem to emerge from entirely random events.

4) Recency Effect

The recency effect is the tendency to give more weight to recent data. Studies have shown participants can more easily remember information at the end of a list than from the middle. The existence of this bias makes it important to gather enough long-term data, so daily up’s and down’s don’t lead to bad decisions.

5) Anchoring Bias

Anchoring is a well-known problem with negotiations. The first person to state a number will usually force the other person to give a new number based on the first. Anchoring happens even when the number is completely random. In one study, participants spun a wheel that either pointed to 15 or 65. They were then asked the number of countries in Africa that belonged to the UN. Even though the number was arbitrary, answers tended to cluster around either 15 or 65.

6) Overconfidence Effect

And you were worried about having too little confidence? Studies have shown that people tend to grossly overestimate their abilities and characteristics from where they should. More than 80% of drivers place themselves in the top 30%.

One study asked participants to answer a difficult question with a range of values to which they were 95% certain the actual answer lay. Despite the fact there was no penalty for extreme uncertainty, less than half of the answers lay within the original margin.

7) Fundamental Attribution Error

Mistaking personality and character traits for differences caused by situations. A classic study demonstrating this had participants rate speakers who were speaking for or against Fidel Castro. Even if the participants were told the position of the speaker was determined by a coin toss, they rated the attitudes of the speaker as being closer to the side they were forced to speak on.

Studies have shown that it is difficult to out-think these cognitive biases. Even when participants in different studies were warned about bias beforehand, this had little impact on their ability to see past them.

What an understanding of biases can do is allow you to design decision making methods and procedures so that biases can be circumvented. Researchers use double-blind studies to prevent bias from contaminating results. Making adjustments to your decision making, problem solving and learning patterns you can try to reduce their effects.

7 Ways To Have More Confident Body Language

7 Ways To Have More Confident Body Language

The popular idiomatic saying that “actions speak louder than words” has been around for centuries, but even to this day, most people struggle with at least one area of nonverbal communication. Consequently, many of us aspire to have more confident body language but don’t have the knowledge and tools necessary to change what are largely unconscious behaviors.

Given that others’ perceptions of our competence and confidence are predominantly influenced by what we do with our faces and bodies, it’s important to develop greater self-awareness and consciously practice better posture, stance, eye contact, facial expressions, hand movements, and other aspects of body language.

Posture

First things first: how is your posture? Let’s start with a quick self-assessment of your body.

  • Are your shoulders slumped over or rolled back in an upright posture?
  • When you stand up, do you evenly distribute your weight or lean excessively to one side?
  • Does your natural stance place your feet relatively shoulder-width apart or are your feet and legs close together in a closed-off position?
  • When you sit, does your lower back protrude out in a slumped position or maintain a straight, spine-friendly posture in your seat?

All of these are important considerations to make when evaluating and improving your posture and stance, which will lead to more confident body language over time. If you routinely struggle with maintaining good posture, consider buying a posture trainer/corrector, consulting a chiropractor or physical therapist, stretching daily, and strengthening both your core and back muscles.

Facial Expressions

Are you prone to any of the following in personal or professional settings?

  • Bruxism (tight, clenched jaw or grinding teeth)
  • Frowning and/or furrowing brows
  • Avoiding direct eye contact and/or staring at the ground

If you answered “yes” to any of these, then let’s start by examining various ways in which you can project confident body language through your facial expressions.

1. Understand How Others Perceive Your Facial Expressions

A December 2020 study by UC Berkeley and Google researchers utilized a deep neural network to analyze facial expressions in six million YouTube clips representing people from over 140 countries. The study found that, despite socio-cultural differences, people around the world tended to use about 70% of the same facial expressions in response to different emotional stimuli and situations.[1]

The study’s researchers also published a fascinating interactive map to demonstrate how their machine learning technology assessed various facial expressions and determined subtle differences in emotional responses.

This study highlights the social importance of facial expressions because whether or not we’re consciously aware of them—by gazing into a mirror or your screen on a video conferencing platform—how we present our faces to others can have tremendous impacts on their perceptions of us, our confidence, and our emotional states. This awareness is the essential first step towards

2. Relax Your Face

New research on bruxism and facial tension found the stresses and anxieties of Covid-19 lockdowns led to considerable increases in orofacial pain, jaw-clenching, and teeth grinding, particularly among women.[2]

The National Institute of Dental and Craniofacial Research estimates that more than 10 million Americans alone have temporomandibular joint dysfunction (TMJ syndrome), and facial tension can lead to other complications such as insomnia, wrinkles, dry skin, and dark, puffy bags under your eyes.[3])

To avoid these unpleasant outcomes, start practicing progressive muscle relaxation techniques and taking breaks more frequently throughout the day to moderate facial tension.[4] You should also try out some biofeedback techniques to enhance your awareness of involuntary bodily processes like facial tension and achieve more confident body language as a result.[5]

3. Improve Your Eye Contact

Did you know there’s an entire subfield of kinesic communication research dedicated to eye movements and behaviors called oculesics?[6] It refers to various communication behaviors including direct eye contact, averting one’s gaze, pupil dilation/constriction, and even frequency of blinking. All of these qualities can shape how other people perceive you, which means that eye contact is yet another area of nonverbal body language that we should be more mindful of in social interactions.

The ideal type (direct/indirect) and duration of eye contact depends on a variety of factors, such as cultural setting, differences in power/authority/age between the parties involved, and communication context. Research has shown that differences in the effects of eye contact are particularly prominent when comparing East Asian and Western European/North American cultures.[7]

To improve your eye contact with others, strive to maintain consistent contact for at least 3 to 4 seconds at a time, consciously consider where you’re looking while listening to someone else, and practice eye contact as much as possible (as strange as this may seem in the beginning, it’s the best way to improve).

3. Smile More

There are many benefits to smiling and laughing, and when it comes to working on more confident body language, this is an area that should be fun, low-stakes, and relatively stress-free.

Smiling is associated with the “happiness chemical” dopamine and the mood-stabilizing hormone, serotonin. Many empirical studies have shown that smiling generally leads to positive outcomes for the person smiling, and further research has shown that smiling can influence listeners’ perceptions of our confidence and trustworthiness as well.

4. Hand Gestures

Similar to facial expressions and posture, what you do with your hands while speaking or listening in a conversation can significantly influence others’ perceptions of you in positive or negative ways.

It’s undoubtedly challenging to consciously account for all of your nonverbal signals while simultaneously trying to stay engaged with the verbal part of the discussion, but putting in the effort to develop more bodily awareness now will make it much easier to unconsciously project more confident body language later on.

5. Enhance Your Handshake

In the article, “An Anthropology of the Handshake,” University of Copenhagen social anthropology professor Bjarke Oxlund assessed the future of handshaking in wake of the Covid-19 pandemic:[8]

“Handshakes not only vary in function and meaning but do so according to social context, situation and scale. . . a public discussion should ensue on the advantages and disadvantages of holding on to the tradition of shaking hands as the conventional gesture of greeting and leave-taking in a variety of circumstances.”

It’s too early to determine some of the ways in which Covid-19 has permanently changed our social norms and professional etiquette standards, but it’s reasonable to assume that handshaking may retain its importance in American society even after this pandemic. To practice more confident body language in the meantime, the video on the science of the perfect handshake below explains what you need to know.

6. Complement Your Verbals With Hand Gestures

As you know by now, confident communication involves so much more than simply smiling more or sounding like you know what you’re talking about. What you do with your hands can be particularly influential in how others perceive you, whether you’re fidgeting with an object, clenching your fists, hiding your hands in your pockets, or calmly gesturing to emphasize important points you’re discussing.

Social psychology researchers have found that “iconic gestures”—hand movements that appear to be meaningfully related to the speaker’s verbal content—can have profound impacts on listeners’ information retention. In other words, people are more likely to engage with you and remember more of what you said when you speak with complementary hand gestures instead of just your voice.[9]

Further research on hand gestures has shown that even your choice of the left or right hand for gesturing can influence your ability to clearly convey information to listeners, which supports the notion that more confident body language is readily achievable through greater self-awareness and deliberate nonverbal actions.[10]

Final Takeaways

Developing better posture, enhancing your facial expressiveness, and practicing hand gestures can vastly improve your communication with other people. At first, it will be challenging to consciously practice nonverbal behaviors that many of us are accustomed to performing daily without thinking about them.

If you ever feel discouraged, however, remember that there’s no downside to consistently putting in just a little more time and effort to increase your bodily awareness. With the tips and strategies above, you’ll be well on your way to embracing more confident body language and amplifying others’ perceptions of you in no time.
