Conspiracy: Making Distinctions

June 2, 2020 by Joycelyn Campbell 1 Comment

While the brain is quite good at categorizing, it is not very adept at making distinctions. (Much like the human brain, neither is Google.)

We encounter this problem in the area of personality or temperament. Just because behavior X is a characteristic of a particular group of people doesn’t mean that every individual in that group will demonstrate behavior X. Believing that everyone in a group demonstrates all of the same characteristics is the basis of stereotyping.

So the problem also routinely arises in regard to ethnicity, gender, nationality, religion, age, and political preference, among others.

Categorizing is an automatic System 1 (unconscious) process. Distinguishing is a System 2 (conscious) process that requires intention, attention, and effort. Categorizing is easy; confirmation bias makes it feel right. Eventually tracks are laid down in the brain that carry us along effortlessly. We have no reason to question our perception. Distinguishing is hard and generates cognitive dissonance, which does not feel good.

Making distinctions after those tracks have been laid down in the brain is called change. Changing our perception of another person or group of people may alter our perception of ourselves, as well. Our sense of self is a construct; our beliefs are one of the things that contribute to that construct. And our brain takes our sense of self very seriously. Changing a belief, therefore, is not a small matter.

What Is Up with Conspiracists?

All of that is by way of getting to some recent thoughts about conspiracy theories currently being floated and about those who have bought into them so completely that they see “evidence” for them everywhere. These people appear to be living in a very different world than I’m living in. If I didn’t already know something about the extent to which we create our own reality, I would have concluded either they are delusional or I am.

But I know that our brains do not allow us to experience reality first-hand or directly. We have to be trained even to be able to see what’s out there. So while there are no doubt extreme conspiracy theorists who are—or border on being—delusional, most of them are simply processing the world differently from the way I process it. And that interests me.

When I started exploring the subject from a psycho-social, neurological, philosophical, and historical perspective, I accessed a few resources I already had. And then I turned to Google, which does a great job of categorizing everything related to conspiracy, but is absolutely abysmal at distinguishing between conspiracy and conspiracy theory.

They are definitely not the same thing. Conspiracies do exist. Conspiracy theories are speculations. Furthermore, the word theory has a broad definition. A conspiracy theory is not the equivalent of a scientific theory, which is the result of research, evidence, and consensus. Good scientists modify or even abandon their theories when new information is uncovered. Conspiracists either reject conflicting information out of hand or expand the theory to incorporate it. More importantly, scientific theories are falsifiable; conspiracy theories are not.

Understanding the Concepts

Here are some definitions (from freedictionary.com):

Conspiracy: (1) an agreement to perform together an illegal, wrongful, or subversive act, (2) an agreement between two or more persons to commit a crime or accomplish a legal purpose through illegal action, (3) a joining or acting together, as if by sinister design.

Examples of conspiracies: Watergate, The Tuskegee Syphilis Experiment, the 1980s Savings and Loan Crisis

Conspiracy Theory: a theory seeking to explain a disputed case or matter as a plot by a secret group or alliance rather than an individual or isolated act.

Examples of conspiracy theories: JFK’s Assassination (various), Moon Landing (didn’t happen), Illuminati (alien shapeshifters who run the world)

Looking for Answers

Some of the questions I’m hoping to answer for myself include:

Who believes conspiracy theories? Are some people more temperamentally inclined to believe them than others?
If a large percentage of a population believes in conspiracy theories, does that have an effect on actual conspiracies (committing or uncovering them, for example)?
What’s going on in the brains of conspiracists vs. non-conspiracists?
Are different groups of people more inclined to believe particular conspiracy theories than others—and does it matter?
How do conspiracy theories affect real-world outcomes?
How can we distinguish possible from highly improbable conspiracies?

I’ll share what I learn. I’m compiling some useful articles on the topic that I will eventually put into a shareable format for anyone who is interested.

I believe this is a timely subject that bridges brain, behavior, and change. And I hope that exploring it may lead to some measure of understanding. We could surely use more of that in our troubled world. What do you think?

You Can’t Live Anywhere
BUT in a Bubble

October 28, 2019 by Joycelyn Campbell Leave a Comment

A character in a story I wrote a long time ago imagines zipping himself closed inside a transparent bubble. As it turns out, we are all living inside our own transparent bubbles; most of us just don’t realize it. We take our experiences at face value. We assume everyone accesses the world the same way we access it, pays attention to what we pay attention to, sees the same colors, and has the same understanding of basic concepts.

Yes, we disagree with some people, but they’re so obviously wrong. The rest of us are on the same page, right?

The topic of the Monthly Meeting of the Mind (& Brain) this month was imagination. One of the participants commented that he has difficulty creating and sustaining visual mental images. The inability to form mental images is called aphantasia. It was identified in the 1880s but only named a few years ago, perhaps because it affects such a small percentage of the population. I can’t imagine being unable to create mental images! Visual mental imagery is an integral aspect of my sense of self and of how I function in the world. I couldn’t be me if I couldn’t do that.

Several years ago I learned about misophonia, also called soft-sound sensitivity. For people with this condition, ordinary sounds the rest of us easily tune out, such as chewing noises, tapping, or rustling paper, can be deeply disturbing. People with misophonia may have such strong physical and emotional reactions to certain sounds they curtail their activities to avoid them. Many more people are affected by misophonia than by aphantasia.

A few months ago I created a handout with a chart using four different colors, including a dark green. So many people saw the color that was clearly green to me (and my computer program) as black or gray or brown that I changed the shade for subsequent copies. These weren’t instances of color blindness, just different visual interpretations.

And then there’s the experience of anger. A lot of people believe anger to be a negative emotion, to be avoided, mitigated, or managed—certainly contained. But others, including me, find that anger can be energizing and even motivating at times. When I described getting angry about an aspect of my health/heart conditions to a friend earlier this month, she tried to persuade me of the value of acceptance. (If you know me, feel free to laugh now.) But I often experience anger that is about something—as opposed to anger at someone—as productive rather than destructive.

That Pesky Four-Letter Word

Lastly there’s a word common to all of us, and whether we use it or someone else uses it, we assume we know exactly what it means. The word is goal. In The Paradox of Choice, Barry Schwartz begins one of his chapters* with this paragraph:

Choosing wisely begins with developing a clear understanding of your goals. And the first choice you must make is between the goal of choosing the absolute best and the goal of choosing something that is good enough.

Does this paragraph make sense to you? Did you sort of nod (at least mentally) in agreement? Apparently it made sense to him.

You could call what Schwartz is talking about a preference, a strategy, a drive, an inclination—you could call it a lot of things, but goal is definitely not one of them. The definition of goal is:

the state of affairs that a plan is intended to achieve and that (when achieved) terminates behavior intended to achieve it.

A goal has an end point. (Visualize a goal post if you can.) It represents a significant change from your current state of affairs, which is why it requires a plan. Once you reach that end point, you no longer need to keep taking the steps you outlined in your plan to get there.

Semantics, you may say. So what?

Well, Schwartz is talking about taking an action that involves choosing something. The most important thing to determine when you’re choosing something is what is your desired outcome not what is the method you are going to use to make the choice. And that’s a lot more than semantics.

So you may know what a goal is and how to set and achieve one. Or you may think getting gas on the way home from work—or making the absolutely best choice—is a goal. In any case, you probably assume others define the word the same way you do.

My Particular Bubble

I can and do create vivid mental images (don’t have aphantasia). I’m bothered by the reverberating bass sounds coming out of speakers in cars next to me at stoplights or the apartment next to mine, but I don’t have misophonia. I can distinguish dark shades of green from black or brown. I don’t experience anger as an entirely negative emotion. And I have a good understanding of what a goal is and how to achieve one.

These are all things I now know are not the same for everyone else. But there are hundreds, maybe thousands, of things I must assume to be the norm for everyone. It’s part of the human condition. It’s also one of the reasons I have always been interested in learning about temperaments or personality types—not for the purpose of “putting people in boxes” but to understand perspectives that are so different from my own.

Your view from your bubble, like my view from mine, is unique. The conditions inside your bubble, like the conditions inside mine, create our personal experience. Rather than taking everything at face value and assuming our experiences or interpretations are valid for everyone else, we might be better off adopting the perspective of one of my former clients, which is:

Isn’t that interesting?

*The subject of this chapter of Schwartz’s book will also be the subject of my next blog post.

The Pleasure of Beauty

August 30, 2019 by Joycelyn Campbell Leave a Comment

The brain takes pleasure in beauty; therefore, it finds beauty rewarding.

No matter where our brain finds beauty—in the natural world, a face or body, a song or work of art, a mathematical equation, or a perfect slice of tiramisu—it responds by activating the same neurological processes. Dopamine signals that a stimulus is rewarding and initiates the motivation and the muscle movements we need to move toward it. Mu-opiod and cannabinoid receptors then work together to produce the experience of pleasure.

We may have our own theories about why we like and take pleasure in some things and not in others. But all our aesthetic experiences are rooted in these processes that take place deep inside the brain.

Although we’re consciously aware of only a tiny fraction of them, our brain processes around 11,000,000 bits of information at a time, most of which are related to vision. The objects in our visual field, whether we’re aware of them or not, have an effect on us. As John Medina says in Brain Rules:

Visual processing doesn’t just assist in the perception of our world. It dominates the perception of our world.

But while it’s often said that beauty is in the eye of the beholder, it’s much more accurate to say that beauty is in the brain of the beholder. Consider a few of the many things we can’t see that we can experience as beautiful, such as:

passages of music
scents and aromas: oranges, jasmine, fresh baked cookies
birds singing in the morning
the warmth of the sun on your skin
an embrace
laughter
rain (the scent, the sound, and the feeling of it)

When an epileptic seizure left painter John Bramblitt legally blind, he learned new ways to carry on with his work.

When you break it down the eyes really only do two things for a painter; they allow you to know your placement on a canvas, and they allow you to determine color. … Basically what I do is replace everything that the eyes would do for a sighted artist with the sense of touch.

The result:

Pleasures are more than simple reflexive reactions to desirable things. —Anjan Chaterjee

Many of our aesthetic preferences—including preferences for sugar, for faces and bodies, and for places in nature—developed during the Pleistocene era. The things we experience as beautiful today connect us not only with each other but also with all of our human ancestors.

Our hard-wired aesthetic preferences are an excellent example of how unconscious processes in the brain operating outside our awareness affect us on a daily basis. We think we’re unique in our preferences and beliefs and in the actions we think we’re choosing to take. Because we don’t understand how and why they developed, we come up with explanations that are bound to miss the mark—and can even lead to strife rather than to cooperation.

However, because we find beautiful things pleasant, they activate the reward system in our brain. The purpose of the reward system is to help us learn and remember things, places, people, and experiences that will contribute to our survival. This makes me hopeful. In our modern splintered world in which humans are continually engaged in various forms of brinksmanship, anything that can help us see ourselves as ultimately part of the same species might yet contribute to our ability to survive.

Aesthetics refers to our appreciation of what is beautiful. Neuroaesthetics is the study of the cognitive (mental) and affective (emotional) processes that underlie aesthetic experiences from a combined neurobiological, psychological, and evolutionary perspective.

How Your Mindset Sets You Up

April 8, 2019 by Joycelyn Campbell Leave a Comment

A mindset is the set of ideas, beliefs, or attitudes with which you approach situations or people—or through which you view them. It determines how you interpret situations and respond to them. Mindsets have something in common with habits since they tend to be habitual, which means largely unconscious. They are a type of mental shortcut; they operate based on assumptions, and they generate expectations.

You can have mindsets about yourself, other people or groups of people, places, situations, events, political organizations, types of music—actually just about anything. A mindset can have surprisingly deep and far-reaching effects.

Mindsets Are Self-Reinforcing

You’ve probably heard someone described as having a victim mentality, which is the same as having a victim mindset. If you have a victim mindset you would tend to:

feel that others are to blame for your misfortunes
believe you are powerless to alter your circumstances
have a primarily external locus of control
be disinclined to take personal responsibility
distrust other people
fail to take positive action on your own behalf

The first three attitudes and beliefs lead to the subsequent three behaviors—which, in turn, confirm the attitudes and beliefs. Like any mindset, a victim mindset causes you to view situations, events, and interpersonal relationships through a distorted filter. It leads you to believe your perception isreality. That’s one of the ways your mindset sets you up.

A Few Other Mindsets (Labels)

I’ve written about the productivity vs. creativity mindsets. Here are some others to consider.

Survivalist
Globalist
Entrepreneurial
Lifelong Learner
Achiever
Maker
Activist
Liberal
Conservative
Libertarian
Progressive
Outsider

Recognizing and Changing a Mindset

When examining a mindset, it’s important to know what it is, when it’s in effect, and how it affects your perception, interpretation, and response. But trying to understand where it came from or how it developed is a side trip that won’t get you closer to altering it. (It doesn’t matter how you came to possess the diffusion filter for your camera lens. Once you install it, it affects what you see when you look through the lens.) Instead, focus on determining your mindset’s attributes: what beliefs, attitudes, personality traits, etc. are part of it?

One of the best ways to catch your mindset in the act is to notice when your expectations of a person or a situation are not met. Instead of pausing to consider the source of your expectations, your brain is more likely to jump into action to find a suitable explanation that will allow you to comfortably fit the experience into your ongoing inner narrative. Unfortunately, even when reality conflicts with your mindset, your brain’s tendency is to interpret what happens in a way that reinforces your mindset.

After you develop an understanding of a mindset you want to change:

Clarify why you want to change it.
Determine your desired outcome.
Identify one situation to change.

Remember that it’s easier to focus on and change a behavior (what you do) than it is to focus on and change a thought, a thought pattern, or a belief. Create an intention to change your behavior in one situation and apply repetition and perseverance until the new behavior or response becomes the status quo.

It isn’t easy to recognize or change a mindset, but if you focus on the mechanics (what, when, and how), you can do it. And it’s worth the effort to open your mind, shift your perspective, and learn how to adjust your personal camera lens filters so you aren’t stuck with whatever lenses you happen to have developed over the course of your life.

Do You Want a Resilient Brain?

March 18, 2019 by Joycelyn Campbell Leave a Comment

The greater your cognitive reserve, the more resilient your brain will be. Brain reserve—or cognitive reserve*—helps your brain adapt and respond to changes and resist damage. It gives it the ability to improvise and find alternate ways of doing a job or performing a task.

Your cognitive reserve begins to develop in childhood and gets stronger as you move through adulthood. If you continue to learn, embrace new activities, and develop new skills and interests, you will continually build and maintain your cognitive reserve.

This is another reason to aim for challenging yourself rather than taking it easy and following the path of least resistance. You don’t know when you’re going to need your cognitive reserve, so it’s good to have as much of it as possible “in the tank.”

Protection from Damage

The concept originated in the 1980s. Researchers discovered that some people who were found at autopsy to have brain changes consistent with advanced Alzheimer’s disease had displayed no apparent symptoms of dementia before they died. These individuals had enough cognitive reserve to offset the damage to their brains to allow them to continue functioning as they always had.

Cognitive reserve can also help stave off degenerative changes associated with other brain diseases, such as Parkinson’s disease, multiple sclerosis, or a stroke.

Even if you’re fortunate enough to never experience any of these diseases, you can still benefit from developing cognitive reserve. It can help you function better—and for longer—when you experience unexpected and stressful life events, which tend to require more effort from your brain.

You can’t prevent yourself from aging or insulate yourself from all stressful, unexpected, or life-altering events. You don’t have total control over what kinds of diseases or deficits your genes might predispose you to develop. But you can do something to moderate how much these challenges affect you, your well being, and your ability to function.

Learning, Curiosity, and Dopamine

Even if you don’t develop neurological or psychological disorders, brain circuits that rely on dopamine tend to decline in function with aging. But curiosity prepares your brain for learning by activating the reward system, enhancing memory and motivation in the process. When you’re learning something you’re deeply—as opposed to idly—curious about, you’re more likely to recall and retain what you learn about that topic. You’re also more likely to retain unrelated information you encounter at the same time.

Curiosity may put the brain in a state that allows it to learn and retain any kind of information, like a vortex that sucks in what you are motivated to learn, and also everything around it. —Matthias Gruber, UC Davis Center for Neuroscience

Curiosity, challenge, and complexity seem to define the path that leads to strong cognitive functioning and a more active and enjoyable life now—and to greater cognitive reserve whenever you may need it.

Have your education, work, and leisure activities challenged you over the years? If so, they have contributed to your cognitive reserve. If not, there’s no time like now to reverse course if you want to do as much as you can to maintain your memory and your cognitive skills for as long as you can. Engaging in a variety of activities—physical, mental, and social—with differing levels of complexity have a synergistic effect. So the more things you do in these areas, the better—for both you and your brain.

*“Brain reserve” is sometimes used to refer to physical changes in the brain such as an increase in neurons and synapses (aka the “hardware”). “Cognitive reserve” is sometimes used to refer to the brain’s capabilities and skills in regard to completing tasks, learning new things, or recall (aka the “software”). These distinctions are really two sides of the same coin, and research is currently being conducted on the relationship between them.
