50 Cognitive Biases in the Modern World
Cognitive biases are widely accepted as something that makes us human.
Every day, systematic errors in our thought process impact the way we live and work. But in a world where everything we do is changing rapidly—from the way we store information to the way we watch TV—what really classifies as rational thinking?
It’s a question with no right or wrong answer, but to help us decide for ourselves, today’s infographic from TitleMax lists 50 cognitive biases that we may want to become privy to.
In the name of self-awareness, here’s a closer look at three recently discovered biases that we are most prone to exhibiting in the modern world.
AI-infused applications are becoming incredibly good at “personalizing” our content, but will there come a time when we let algorithms make all of our decisions?
Automation bias refers to the tendency to favor the suggestions of automated systems.
Take Netflix, for example. Everything we see on the platform is the result of algorithms—even the preview images that are generated. Then, to harness the power of data and machine learning, Netflix categorizes its content into tens of thousands of micro-genres. Pairing these genre tags with a viewer’s history allows them to assign several of over 2,000 “taste profiles” to each user.
And while there’s nothing wrong with allowing Netflix to guide what we watch, there’s an enormous sea of content standing by. Estimates from 2015 claimed it would take nearly four years to watch all of Netflix’s content. Thousands more hours of content have since been added.
If we want to counter this cognitive bias, finding a new favorite series on platforms like Netflix may require some good old-fashioned human curiosity.
The Google Effect
Also known as “digital amnesia”, the aptly named Google Effect describes our tendency to forget information that can be easily accessed online.
First described in 2011 by Betsy Sparrow (Columbia University) and her colleagues, their paper described the results of several memory experiments involving technology.
In one experiment, participants typed trivia statements into a computer and were later asked to recall them. Half believed the statements were saved, and half believed the statements were erased. The results were significant: participants who assumed they could look up their statements did not make much effort to remember them.
Because search engines are continually available to us, we may often be in a state of not feeling we need to encode the information internally. When we need it, we will look it up.
– Sparrow B, et al. Science 333, 777 (2011)
Our modern brains appear to be re-prioritizing the information we hold onto. Notably, the study doesn’t suggest we’re becoming less intelligent—our ability to learn offline remains the same.
The IKEA Effect
Identified in 2011 by Michael Norton (Harvard Business School) and his colleagues, this cognitive bias refers to our tendency to attach a higher value to things we help create.
Combining the Ikea Effect with other related traits, such as our willingness to pay a premium for customization, is a strategy employed by companies seeking to increase the intrinsic value that we attach to their products.
For instance, American retailer Build-A-Bear Workshop is anchored around creating a highly interactive customer experience. With the help of staff, children (or adults) can assemble their stuffed animals from scratch, then add clothing and accessories at extra cost.
Nike also incorporates this bias into its offering. The footwear company offers a Nike By You line of customizable products, where customers pay a premium to design bespoke shoes with an extensive online configurator.
While there’s nothing necessarily wrong with our susceptibility to the Ikea Effect, understanding its significance may help us make more appropriate decisions as consumers.
What Can We Do?
As we navigate an increasingly complex world, it’s natural for us to unconsciously adopt new patterns of behavior.
Becoming aware of our cognitive biases, and their implications, can help us stay on the right course.
Visualizing Two Decades of Reported Hate Crimes in the U.S.
Hate crimes across the U.S. have been on the rise since 2014. Here’s a look at the most common types of offenses over the years.
Visualizing Two Decades of Reported Hate Crimes in the U.S.
Across the U.S., thousands of hate crimes are committed each year, with many different motivating biases.
In 2020 alone, more than 10,000 unique hate crime incidents were reported to the Federal Bureau of Investigation (FBI)—and it’s likely that thousands more were committed that didn’t get reported to law enforcement.
What are the most commonly reported motivating biases, and how have hate crime rates evolved over the years? This graphic uses data from the FBI to visualize two decades of reported hate crime incidents across America.
What is Considered a Hate Crime?
Before diving in, it’s important to determine what constitutes a hate crime.
According to the U.S. Department of Justice, a hate crime is a crime that’s “committed on the basis of the victim’s perceived or actual race, color, religion, national origin, sexual orientation, gender, gender identity, or disability.”
These types of crimes are a threat to society, as they have a broader impact on communities than other types of crimes do. This is because hate crimes can foster fear and intimidate large groups of people or marginalized communities, making them feel unwelcome, unsafe, or othered.
Hate Crimes on the Rise
Hate crimes have been rising across the U.S. in nearly every year since 2014. By 2020, reported crimes across America reached record-level highs not seen in over two decades.
|Year||Number of Reported Incidents||% Change (y-o-y)|
And sadly, these figures are likely a vast undercount. Law enforcement submit this data to the FBI of their own volition, and in 2020, thousands of agencies did not submit their crime statistics.
Race-Related Hate Crimes are Most Common
Historically, the most reported hate crimes in the U.S. are related to race. In 2020, about 66% of incidents were motivated by discrimination against the victim’s race or ethnicity.
|Type of Bias||Total Number of Crimes (2020)||% of Total|
While race is the most commonly reported hate crime, incidents related to gender and gender identity are on the rise—in 2020, there was a 9% increase in gender-related incidents, and a 34% increase in gender identity-related incidents, compared to 2019 figures.
Visualizing the Relationship Between Cancer and Lifespan
New research links mutation rates and lifespan. We visualize the data supporting this new framework for understanding cancer.
A Newfound Link Between Cancer and Aging?
A new study in 2022 reveals a thought-provoking relationship between how long animals live and how quickly their genetic codes mutate.
Cancer is a product of time and mutations, and so researchers investigated its onset and impact within 16 unique mammals. A new perspective on DNA mutation broadens our understanding of aging and cancer development—and how we might be able to control it.
Mutations, Aging, and Cancer: A Primer
Cancer is the uncontrolled growth of cells. It is not a pathogen that infects the body, but a normal body process gone wrong.
Cells divide and multiply in our bodies all the time. Sometimes, during DNA replication, tiny mistakes (called mutations) appear randomly within the genetic code. Our bodies have mechanisms to correct these errors, and for much of our youth we remain strong and healthy as a result of these corrective measures.
However, these protections weaken as we age. Developing cancer becomes more likely as mutations slip past our defenses and continue to multiply. The longer we live, the more mutations we carry, and the likelihood of them manifesting into cancer increases.
A Biological Conundrum
Since mutations can occur randomly, biologists expect larger lifeforms (those with more cells) to have greater chances of developing cancer than smaller lifeforms.
Strangely, no association exists.
It is one of biology’s biggest mysteries as to why massive creatures like whales or elephants rarely seem to experience cancer. This is called Peto’s Paradox. Even stranger: some smaller creatures, like the naked mole rat, are completely resistant to cancer.
This phenomenon motivates researchers to look into the genetics of naked mole rats and whales. And while we’ve discovered that special genetic bonuses (like extra tumor-suppressing genes) benefit these creatures, a pattern for cancer rates across all other species is still poorly understood.
Cancer May Be Closely Associated with Lifespan
Researchers at the Wellcome Sanger Institute report the first study to look at how mutation rates compare with animal lifespans.
Mutation rates are simply the speed at which species beget mutations. Mammals with shorter lifespans have average mutation rates that are very fast. A mouse undergoes nearly 800 mutations in each of its four short years on Earth. Mammals with longer lifespans have average mutation rates that are much slower. In humans (average lifespan of roughly 84 years), it comes to fewer than 50 mutations per year.
The study also compares the number of mutations at time of death with other traits, like body mass and lifespan. For example, a giraffe has roughly 40,000 times more cells than a mouse. Or a human lives 90 times longer than a mouse. What surprised researchers was that the number of mutations at time of death differed only by a factor of three.
Such small differentiation suggests there may be a total number of mutations a species can collect before it dies. Since the mammals reached this number at different speeds, finding ways to control the rate of mutations may help stall cancer development, set back aging, and prolong life.
The Future of Cancer Research
The findings in this study ignite new questions for understanding cancer.
Confirming that mutation rate and lifespan are strongly correlated needs comparison to lifeforms beyond mammals, like fishes, birds, and even plants.
It will also be necessary to understand what factors control mutation rates. The answer to this likely lies within the complexities of DNA. Geneticists and oncologists are continuing to investigate genetic curiosities like tumor-suppressing genes and how they might impact mutation rates.
Aging is likely to be a confluence of many issues, like epigenetic changes or telomere shortening, but if mutations are involved then there may be hopes of slowing genetic damage—or even reversing it.
While just a first step, linking mutation rates to lifespan is a reframing of our understanding of cancer development, and it may open doors to new strategies and therapies for treating cancer or taming the number of health-related concerns that come with aging.
