Every Single Cognitive Bias in One Infographic

The human brain is capable of incredible things, but it’s also extremely flawed at times.
Science has shown that we tend to make all sorts of mental mistakes, called “cognitive biases”, that can affect both our thinking and actions. These biases can lead to us extrapolating information from the wrong sources, seeking to confirm existing beliefs, or failing to remember events the way they actually happened!
To be sure, this is all part of being human – but such cognitive biases can also have a profound effect on our endeavors, investments, and life in general. For this reason, today’s infographic from DesignHacks.co is particularly handy. It shows and groups each of the 188 known confirmation biases in existence.
What is a Cognitive Bias?
Humans tend to think in certain ways that can lead to systematic deviations from making rational judgments.
These tendencies usually arise from:
- Information processing shortcuts
- The limited processing ability of the brain
- Emotional and moral motivations
- Distortions in storing and retrieving memories
- Social influence
Cognitive biases have been studied for decades by academics in the fields of cognitive science, social psychology, and behavioral economics, but they are especially relevant in today’s information-packed world. They influence the way we think and act, and such irrational mental shortcuts can lead to all kinds of problems in entrepreneurship, investing, or management.
Cognitive Bias Examples
Here are four examples of how these types of biases can affect people in the business world:
Familiarity Bias: An investor puts her money in “what she knows”, rather than seeking the obvious benefits from portfolio diversification. Just because a certain type of industry or security is familiar doesn’t make it the logical selection.
Self-Attribution Bias: An entrepreneur overly attributes his company’s success to himself, rather than other factors (team, luck, industry trends). When things go bad, he blames these external factors for derailing his progress.
Anchoring Bias: An employee in a salary negotiation is too dependent on the first number mentioned in the negotiations, rather than rationally examining a range of options.
Survivorship Bias: Entrepreneurship looks easy, because there are so many successful entrepreneurs out there. However, this is a cognitive bias: the successful entrepreneurs are the ones still around, while the millions who failed went and did other things.
These Powerful Maps Show the Extremes of U.S. Population Density
The U.S. population is spread across a huge amount of land, but its distribution is far from equal. These maps are a unique look at population density
America’s 328 million people are spread across a huge amount of territory, but the population density of various regions is far from equal.
It’s no secret that cities like New York have a vastly different population density than, say, a rural county in North Dakota. Even so, this interactive map by Ben Blatt of Slate helps visualize the stark contrast between urban and rural densities in a way that might intrigue you.
How many counties does it take to equal the population of these large urban areas? Let’s find out.
New York City’s Rural Equivalent
New York City (proper) Population: 8.42 million
New York City Population density: 27,547 persons / mi²
New York City became the largest city in the U.S. back in 1781 and has long been the country’s most densely packed urban center. Today, 1 in every 38 people living in the United States resides in The Big Apple.
For the northwestern counties above to match the population of New York City, it takes a land area around the size of Mongolia. The region shown above is 645,934 mi², and runs through portions of 12 different states.
In order to match the population of the entire New York metropolitan area, which holds 18 million people and includes adjacent cities and towns in New York state, New Jersey, and Connecticut, the above equivalent area would have to be even more massive.
Los Angeles County’s Rural Equivalent
LA County Population: 10.04 million
LA County Population density: 2,100 persons / mi²
Los Angeles County is home to the 88 incorporated cities that make up the urban area of Los Angeles.
Even excluding nearby population centers such as Anaheim, San Bernadino, and Riverside (which are located in adjacent counties) it is still the most populous county in the United States, with over 10 million inhabitants.
To match this enormous scale in Middle America, it would take 298 counties covering an area of 471,941 mi².
Chicago’s Rural Equivalent
Chicago Metropolitan Area Population: 9.53 million
Chicago Metropolitan Area Population density: 1,318 persons / mi²
Next up is America’s third largest city, Chicago. For this visualization, we’re using the Chicago metropolitan area, which covers the full extent of the city’s population.
To match the scale of the population of the Windy City, we would need to add up every county in New Mexico, along with large portions of Colorado, Arizona, and Texas.
Turning the Tables?
Conversely, what if we transported the people in the country’s least densely populated counties into the middle of an urban center?
|1||Kalawao County, Hawaii||86|
|2||Loving County, Texas||169|
|3||King County, Texas||272|
|4||Kenedy County, Texas||404|
|5||Arthur County, Nebraska||463|
As it turns out, the total population of the five least populated counties is just 1,394—roughly the same amount of people that live on the average Manhattan block.
Visualized: Comparing the Titanic to a Modern Cruise Ship
The sheer size of the Titanic was a sight to behold in 1912, but over 100 years later, how does this vessel compare to a modern cruise ship?
Remembering the Tragedy of the Titanic
When the Titanic was completed on April 2, 1912, it was the largest and perhaps most luxurious ship in the world. The vessel could hold over 3,300 people including crew members, and boasted various amenities including a swimming pool and squash court.
The Titanic’s impressive size attracted many of the world’s wealthiest individuals, and on April 10, 1912, it set out on its maiden voyage. Just five days later, the ship sank after hitting an iceberg, resulting in more than 1,500 deaths.
It’s been over 100 years since the Titanic’s demise, so how have passenger ships evolved?
To find out, we’ve visualized it beside Royal Caribbean’s Symphony of the Seas, currently the world’s largest cruise ship.
The Size of the Titanic, in Perspective
The following table lists the dimensions of both ships to provide a better understanding of the Titanic’s relative size.
|RMS Titanic||Symphony of the Seas|
|Length||882ft (269m)||1,184ft (361m)|
|Width||92ft (28m)||215ft (66m)|
|Height||175ft (53m)||238ft (73m)|
|Internal volume||46,328 gross register tonnage (grt)||228,081 gross tonnage (gt)|
Source: Owlcation, Insider
Note: Gross register tonnage (grt) is a historic measure of a ship’s internal volume. This metric was replaced by gross tonnage (gt) on July 18, 1982.
One of the biggest differences between these two ships is width, with the latter being more than twice as wide. This is likely due to the vast amenities housed within the Symphony of the Seas, which includes 24 pools, 22 restaurants, 2 rock climbing walls, an ice-skating rink, and more. With accommodations for 6,680 passengers, the Symphony of the Seas also supports a crew that is 147% larger.
The Symphony of the Seas clearly surpasses the Titanic in terms of size, but there’s also a substantial difference in cost. When converted to today’s dollars, the bill for the Titanic equates to roughly $400 million, less than half of the Symphony of the Seas’ cost of $1.35 billion.
Lessons Learned from the Disaster
Inadequate safety preparations were a contributor to the Titanic’s high death toll. During its journey, the vessel carried enough lifeboats to accommodate just 33% of its total passengers and crew. This was legal at the time, as regulations based a ship’s number of required lifeboats on its weight, rather than its passenger capacity.
To make matters worse, investigations determined that the Titanic’s lifeboats had not been used to their full capacity, and that a scheduled lifeboat drill had been cancelled by the ship’s captain. These shortfalls, among others, paved the way for numerous improvements in maritime safety regulation.
These include the creation of the International Convention for the Safety of Life at Sea Treaty (SOLAS) in 1914, which is still in force today. Regarded as the most important international treaty on ship safety, SOLAS has been updated numerous times and is followed by 164 states, which together flag 99% of merchant ships (by gross tonnage) on the high seas today.
