We are each entitled to our own personal world view.
Unfortunately, when it comes to interpreting information and making objective sense of reality, human brains are hard-wired to make all kinds of mental mistakes that can impact our ability to make rational judgments.
In total, there are 180+ cognitive biases that mess with how we process data, think critically, and perceive reality.
Flawed Human Reasoning
There is no simple way to get around these basic human instincts, but one thing that we can do is understand the specific mistakes we make and why.
Today’s infographic comes to us from School of Thought, a non-profit dedicated to spreading critical thinking. The graphic describes 24 of the key biases that warp our sense of reality, providing useful examples along the way.
At the beginning of the infographic, you may have noticed illustrations of two gentlemen.
In case you were wondering, those happen to represent Daniel Kahneman and Amos Tversky, two of the leading social scientists known for their contributions to this field. Not only did they pioneer work around cognitive biases starting in the late 1960s, but their partnership also resulted in a Nobel Prize in Economics in 2002.
Biases Distorting Reality
Here are a few examples of particular biases that work to warp your perception of what is real:
You remember the past as better than it was, and expect the future to be worse than it is likely to be. This is an interesting one, since statistically this is one of the most peaceful and prosperous times in history – yet the 24-hour news cycle rarely reflects this. (For a good example how the world is improving, see these six charts)
Just World Hypothesis:
Your preference for a just world makes you presume that it exists. Of course, it’s uncomfortable to think that the world is unfair, but by understanding this you will make more accurate judgments about people and situations.
If a conclusion supports your existing beliefs, you’ll rationalize anything that supports it. In other words, instead of willingly looking at new information, we are primed to defend our own ideas without actually questioning them.
Context and delivery can have a big impact on how a story is interpreted. We must have the humility to recognize that we can be manipulated, and work to limit the effect that framing has on our critical thinking.

The Shape of the World, According to Old Maps
What did ancient maps look like, before we had access to airplanes and satellites? See the evolution of the world map in this nifty infographic.
The Shape of the World, According to Ancient Maps
A Babylonian clay tablet helped unlock an understanding for how our ancestors saw the world.
Dating all the way back to the 6th century BCE, the Imago Mundi is the oldest known world map, and it offers a unique glimpse into ancient perspectives on earth and the heavens.
While this is the first-known interpretation of such a map, it would certainly not be the last. Today’s visualization, designed by Reddit user PisseGuri82, won the “Best of 2018 Map Contest” for depicting the evolving shapes of man-made maps throughout history.
AD 150: Once Upon A Time in Egypt
In this former location of the Roman Empire, Ptolemy was the first to use positions of latitude and longitude to map countries into his text Geographia. After these ancient maps were lost for centuries, Ptolemy’s work was rediscovered and reconstructed in the 15th century, serving as a foundation for cartography throughout the Middle Ages.
1050: Pointing to the Heavens
The creation of this quintessential medieval T-and-O Beatine map is attributed not to an unknown French monk, but to the Spanish monk Beatus of Liébana. Although it shows several continents—Africa, Asia, and Europe—its main objective was to visualize Biblical locations. For example, because the sun rises in the east, Paradise (The Garden of Eden) can be seen pointing upwards and towards Asia on the map.
1154: The World Turned Upside Down
The Arabic geographer Muhammad al-Idrisi made one of the most advanced medieval world maps for King Roger II of Sicily. The Tabula Rogeriana, which literally translates to “the book of pleasant journeys into faraway lands”, was ahead of the curve compared to contemporaries because it used information from traveler and merchant accounts. The original map was oriented south-up, which is why modern depictions show it upside down.
1375: The Zenith of Medieval Map Work
The Jewish cartographer Abraham Cresques created the most important map of the medieval period, the Catalan Atlas, with his son for Prince John of Aragon. It covers the “East and the West, and everything that, from the Strait [of Gibraltar] leads to the West”. Many Indian and Chinese cities can be identified, based on various voyages by the explorers Marco Polo and Sir John Mandeville.
After this, the Age of Discovery truly began—and maps started to more closely resemble the world map as we know it today.
1489: Feeling Ptolemy and Polo’s Influences
The 15th century was a radical time for map-makers, once Ptolemy’s geographical drawings were re-discovered. Henricus Martellus expanded on Ptolemaic maps, and also relied on sources like Marco Polo’s travels to imagine the Old World. His milestone map closely resembles the oldest-surviving terrestrial globe, Erdapfel, created by cartographer Martin Behaim. Today, it’s preserved at the Yale University archives.
1529: A Well-Kept Spanish Secret
The first ever scientific world map is most widely attributed to the Portuguese cartographer Diego Ribero. The Padrón Real was the Spanish Crown’s official and secret master map, made from hundreds of sailors’ reports of any new lands and their coordinates.
1599: The Wright Idea
English mathematician and cartographer Edward Wright was the first to perfect the Mercator projection—which takes the Earth’s curvature into consideration. Otherwise known as a Wright-Molyneux world map, this linear representation of the earth’s cylindrical map quickly became the standard for navigation.
1778-1832: The Emergence of Modern World Maps
The invention of the marine chronometer transformed marine navigation—as ships were now able to detect both longitude and latitude. Jacques-Nicolas Bellin, a French geographer, was responsible for the 18th century’s highly accurate world maps and nautical charts. His designs favored functionality over the decorative flourishes of cartographers past.
Finally, the German cartographer and lawyer Adolf Stieler was the man behind Stieler’s Handatlas, the leading German world atlas until the mid-20th century. His maps were famous for being updated based on new explorations, making them the most reliable map possible.
Is There Uncharted Territory Left?
It is worth mentioning that these ancient maps above are mostly coming from a European perspective.
That said, the Islamic Golden Age also boasts an impressive cartographic record, reaching its peak partially in thanks to Muhammad al-Idrisi in the 11th century. Similarly, Ancient Chinese empires had a cartographic golden age after the invention of the compass as well.
Does this mean there’s nothing left to explore today? Quite the contrary. While we know so much about our landmasses, the undersea depths remain quite a mystery. In fact, we’ve explored more of outer space than we have 95% of our own oceans.

The Extreme Temperatures of the Universe
From the Big Bang to the Boomerang Nebula, this stunning data visualization puts the extreme temperatures of our universe into perspective.
The Extreme Temperatures of the Universe
For most of us, temperature is a very easy variable to overlook.
Our vehicles and indoor spaces are climate controlled, fridges keep our food consistently chilled, and with a small twist of the tap, we get water that’s the optimal temperature. Of course, our concept of what’s hot or cold is actually very narrow in the grand scheme of things.
Even the stark contrast between the wind-swept glaciers of Antarctica and the blistering sands of our deserts is a mere blip on the universe’s full temperature range. Today’s graphic, produced by the IIB Studio, looks at the hottest and coldest temperatures in our universe.
But First: What is Temperature Anyway?
Before looking at this top-to-bottom view of extreme temperatures, it helps to remember what temperature is actually measuring – kinetic energy, or the movement of atoms.
Hypothetically, atoms would simply stop moving as they reach absolute zero. As matter heats up, it begins to “vibrate” more vigorously, changing states from solid to gas. Eventually, plasma forms as electrons wander away from the nuclei.
With that quick primer, let’s dig into some of the hottest insights in this cool data visualization.
Highs and Lows on Planet Earth
Earth’s lowest air temperature, -135ºF (-93ºC), was recorded in Antarctica in 2010. Since then, scientists have discovered that surface ice temperatures can dip as low as -144ºF (-98ºC).
The conditions need to be just right: clear skies and dry air must persist for several days during the polar winter. In surroundings this cold, human lungs would actually hemorrhage within just a few breaths.
On the other end of the spectrum of extreme temperatures, the hottest surface reading on Earth of 160ºF (71ºC) occurred in Iran’s Lut Desert in 2005. In fact, the Lut Desert clocked the highest surface temperature in 5 out of 7 years during a 2003-2009 study, making it the world’s hottest location. The desert’s dark pebbles, dry soil, and lack of vegetation create the perfect conditions for blistering heat.
There are very few organisms that can withstand such temperatures, but one fascinating phylum makes the cut.
The Amazing Tardigrade
Commonly known as a “moss pig” or “water bear”, the one-millimeter long tardigrade is extremely resilient. While most organisms need water to survive, the tardigrade gets around this by entering a “tun” state, in which metabolism slows to just 0.01% of its normal rate.
When water is scarce, the creature curls up and synthesizes molecules that lock sensitive cell components in place until re-hydration occurs. Beyond dry conditions, the tardigrade can also survive both freezing and boiling temperatures, high radiation environments, and even the vacuum of space.
This video courtesy of TEDEd explains more about the hardy critter:
Testing the Limits
For better or worse, humans have pushed the limits of temperature here on Earth.
At MIT, scientists cooled a sodium gas to half-a-billionth of a degree above absolute zero. In the words of the Nobel Laureate Wolfgang Ketterle, who co-led the team: “To go below one nanokelvin (one-billionth of a degree) is a little like running a mile under four minutes for the first time.”
Not all experiments are conducted out of simple curiosity. Conventional bombs already explode at around 9,000ºF (5,000ºC), but nuclear explosions take things much further. For a split second, temperatures inside a nuclear fireball can reach a mind-bending 18,000,000ºF (10,000,000ºC).
The highest man-made temperature ever recorded is 9,900,000,000,000ºF (5,500,000,000,000ºC), created in the Large Hadron Collider at CERN in Switzerland. It was achieved by accelerating heavy lead ions to 99% the speed of light and smashing them together.
Highs and Lows of the Universe
While humans have been able to manufacture extremely hot and cold temperatures, the universe has created these extremes naturally.
Undoubtedly, the creation of the universe is made of the hottest stuff of all. The temperature of the universe at 10⁻³⁵ seconds old was a whopping 1 octillion ºC. Moments later, it “cooled down” to 1,800,000,000ºF (1 billion ºC) when the universe was less than two minutes old.
On the other end of the spectrum, the coolest natural place currently known in the universe is the Boomerang Nebula at -457.6ºF (-272ºC). It’s found 5,000 light years away from us in the constellation Centaurus, and it is currently in a transitional phase as a dying star.
As space exploration goes further than ever, these extreme temperatures may one day reach even hotter or colder heights than we can imagine.
