50 Cognitive Biases in the Modern World

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.
Automation Bias
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.

The Head of State of Each Country By Age and Generation
How many world leaders are in each generation?
This visualization by Edit Gyenge visualizes the ages of every nation’s head of state as of March 22, 2023, comparing them with the median population of the respective country. It uses data from the CIA World Factbook and Wikipedia.
Editor’s note: This visualization looks specifically at heads of state. It should be mentioned that depending on the system of government in a country, heads of state shown here may or may not have actual political power. In some countries, the head of state may be a ceremonial position that does not impact day-to-day governance.

Though ages vary across countries and regions, Africa has both the oldest and youngest heads of state in the world today.
Last month, Cameroon’s president Paul Biya celebrated his 90th birthday, making him the oldest head of state in the world in a country that has a median population age of just 18.5 years. The African continent is home to about one-third of the world’s silent generation heads of states.
At the other age extreme, 35-year-old Ibrahim Traoré became the youngest head of state in Burkina Faso after a coup d’etat in September 2022.
Traoré is not the only millennial head of state out there. He is joined by others including Chile’s Gabriel Boric, and North Korea’s well-known Kim Jong-un.
Baby Boomers Lead the Way
Born between 1946 and 1964, the baby boomer generation dominates the world’s state leadership roles today.
Over 58% of the world’s heads of state are in this generation, including the UK’s King Charles III who is the head of state of 15 total nations.
Boomers also make up the largest share of women leaders in the top state positions today. While only around 10% of the world’s nations have women head of states, 65% of them are in this generation.
Included in this subset are heads of state such as Peru’s president Dina Boluarte, Honduras’ president Xiomara Castro, and India’s president Droupadi Murmu.
Where Gen X Takes the Lead
According to historical trends, one might expect to see an American president from Generation X in office sometime soon, but that has not yet materialized for various reasons.
However, this generation has made their mark in other parts of the world as heads of state, especially in Europe.
The presidents of Ukraine (Volodymyr Zelenskyy), France (Emmanuel Macron), and Hungary (Katalin Novák) are in Gen X, and are also Europe’s youngest heads of state.
