A Visual Guide to Human Emotion
Despite vast differences in culture around the world, humanity’s DNA is 99.9% similar.
There are few attributes more central and universal to the human experience than our emotions. Of course, the broad spectrum of emotions we’re capable of experiencing can be difficult to articulate. That’s where this brilliant visualization by the Junto Institute comes in.
This circular visualization is the latest in an ongoing attempt to neatly categorize the full range of emotions in a logical way.
A Taxonomy of Human Emotion
Our understanding has come a long way since William James proposed four basic emotions – fear, grief, love, and rage—though these core emotions still form much of the foundation for current frameworks.
The wheel visualization above identifies six root emotions:
From these six emotions, more nuanced descriptions emerge, such as jealousy as a subset of anger, and awe-struck as a subset of surprise. In total, there are 102 second- and third-order emotions listed on this emotion wheel.
Reinventing the Feeling Wheel
The concept of mapping the range of human emotions on a wheel picked up traction in the 1980s, and has evolved ever since.
One of these original concepts was developed by American psychologist Robert Plutchik, who mapped eight primary emotions—anger, fear, sadness, disgust, surprise, anticipation, trust, and joy. These “high survival value” emotions were believed to be the most useful in keeping our ancient ancestors alive.
Another seminal graphic concept was developed by author Dr. Gloria Willcox. This version of the emotions wheel has spawned dozens of similar designs, as people continue to try to improve on the concept.
The more we research human emotion, the more nuanced our understanding becomes in terms of how we react to the world around us.
Researchers at UC Berkeley used 2,185 short video clips to elicit emotions from study participants. Study participants rated the videos using 27 dimensions of self-reported emotional experience, and the results were mapped in an incredible interactive visualization. It is interesting to note that some video clips garnered a wide array of responses, while other clips elicit a near unanimous emotional response.
Here are some example videos and the distribution of responses:
The data visualization clusters these types of videos together, giving us a unique perspective on how people respond to certain types of stimuli.
Much like emotion itself, our desire to understand and classify the world around us is powerful and uniquely human.
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.
