24 Cognitive Biases That Are Warping Your Perception of Reality

Published

on

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.

24 Cognitive Biases That Are Warping Your Perception of Reality

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:

Declinism:
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.

Belief Bias
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.

Framing Effect:
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.

As the Worlds Turn: Visualizing the Rotation of Planets

Rotation can have a big influence on a planet’s habitability. These animations show how each planet in the solar system moves to its own distinct rhythm.

As the Worlds Turn: Visualizing the Rotations of Planets

The rotation of planets have a dramatic effect on their potential habitability.

Dr. James O’Donoghue, a planetary scientist at the Japanese space agency who has the creative ability to visually communicate space concepts like the speed of light and the vastness of the solar system, recently animated a video showing cross sections of different planets spinning at their own pace on one giant globe.

Cosmic Moves: The Rotation of the Planets

Each planet in the solar system moves to its own rhythm. The giant gas planets (Jupiter, Saturn, Uranus, and Neptune) spin more rapidly on their axes than the inner planets. The sun itself rotates slowly, only once a month.

PlanetRotation Periods (relative to stars)
Mercury58d 16h
Venus243d 26m
Earth23h 56m
Mars24h 36m
Jupiter9h 55m
Saturn10h 33m
Uranus17h 14m
Neptune16h

The planets all revolve around the sun in the same direction and in virtually the same plane. In addition, they all rotate in the same general direction, with the exceptions of Venus and Uranus.

In the following animation, their respective rotation speeds are compared directly:

The most visually striking result of planetary spin is on Jupiter, which has the fastest rotation in the solar system. Massive storms of frozen ammonia grains whip across the surface of the gas giant at speeds of 340 miles (550 km) per hour.

Interestingly, the patterns of each planet’s rotation can help in revealing whether they can support life or not.

Rotation and Habitability

As a fish in water is not aware it is wet, so it goes for humans and the atmosphere around us.

New research reveals that the rate at which a planet spins is an essential component for supporting life. Not only does rotation control the length of day and night, bit it influences atmospheric wind patterns and the formation of clouds.

The radiation the Earth receives from the Sun concentrates at the equator. The Sun heats the air in this region until it rises up through the atmosphere and moves towards the poles of the planet where it cools. This cool air falls through the atmosphere and flows back towards the equator.

This process is known as a Hadley cell, and atmospheres can have multiple cells:

Hadley Cells

A planet with a quick rotation forms Hadley cells at low latitudes into different bands that encircle the planet. Clouds become prominent at tropical regions, which reflect a proportion of the light back into space.

For a planet in a tighter orbit around its star, the radiation received from the star is much more extreme. This decreases the temperature difference between the equator and the poles, ultimately weakening Hadley cells. The result is fewer clouds in tropical regions available to protect the planet from intense heat, making the planet uninhabitable.

Slow Rotators: More Habitable

If a planet rotates slower, then the Hadley cells can expand to encircle the entire world. This is because the difference in temperature between the day and night side of the planet creates larger atmospheric circulation.

Slow rotation makes days and nights longer, such that half of the planet bathes in light from the sun for an extended period of time. Simultaneously, the night side of the planet is able to cool down.

This difference in temperature is large enough to cause the warm air from the day side to flow to the night side. This movement of air allows more clouds to form around a planet’s equator, protecting the surface from harmful space radiation, encouraging the possibility for the right conditions for life to form.

The Hunt for Habitable Planets

Measuring the rotation of planets is difficult with a telescope, so another good proxy would be to measure the level of heat emitted from a planet.

An infrared telescope can measure the heat emitted from a planet’s clouds that formed over its equator. An unusually low temperature at the hottest location on the planet could indicate that the planet is potentially a habitable slow rotator.

Of course, even if a planet’s rotation speed is just right, many other conditions come into play. The rotation of planets is just another piece in the puzzle in identifying the next Earth.

Visualizing the U.S. Airports with the Worst Flight Delays

With flight travel more than tripling in the past 30 years, we break down the most notorious airports in the U.S. with the worst flight delays.

Visualizing the U.S. Airports with the Worst Flight Delays

They say good things come to those who wait. In the case of flight passengers, however, some may be waiting much longer than others.

With frequent flights comes frequent problems. Unexpected travel irritations, delays, and cancellations are all common issues faced by flyers the world over. Correspondingly, certain airports have developed a reputation for making their passengers wait.

Today’s interactive chart from USAFacts shows the percentage of flights delayed, as well as the average length of those delays, at U.S. airports between October 2018 and September 2019.

The Top 10 Airports With the Longest Delays

In the worst airports across the country, over 25% of all flights get delayed. Here is a list of the top offenders based on percentage of flights delayed and the average delay, according to flight data.

RankCity
AirportPercent of Flights Arriving LateAverage Delay Across Flights
#1NewarkNewark Liberty International 26.5%22 minutes
#2New YorkLaGuardia24.5%19.6 minutes
#3ChicagoChicago O'Hare International 25.5%19.2 minutes
#4BostonLogan International22%17.3 minutes
#5DallasDallas/Fort Worth International23.3%16.5 minutes
#6San FranciscoSan Francisco International22.4%16.2 minutes
#7Fort LauderdaleFort Lauderdale-Hollywood International21.9%16.3 minutes
#8DenverDenver International21.6%15.3 minutes
#9MiamiMiami International21.6%15.3 minutes
#10ChicagoChicago Midway22%13.4 minutes

Newark Liberty International takes the top spot, with 26.5% of all flights taking off late. To make matters worse, it also had the longest average delay time, at 22 minutes per flight. The runner-up is another New York-based airport, LaGuardia, averaging close to 20 minutes per flight delay.

The third worst offender was Chicago O’Hare International airport, where over a quarter of flights arrived late, with an average delay of 19 minutes. Chicago O’Hare International saw more flights than Newark and LaGuardia combined, making average delays more costly.

What’s Behind These Major Flight Delays?

While the New York area hosts two of the worst airports in the country, flight delays are exacerbated by a number of regional factors.

First, it hosts one of the busiest air corridors worldwide. As a result, any unexpected interruption or delay has an outsized effect on flights arriving at their destination on time.

Coupled with this is the commanding presence of United Airlines. As one of the largest airlines in the world, it operates over 401 daily flights at Newark airport. Additionally, United has been known to have operational issues. For example, in June 2019, significant aircraft problems led the Newark airport to suspend flights altogether.

There are four major causes of flight delays: poor weather conditions, late aircraft, carrier related (such as baggage, fueling, or maintenance problems), and airspace system issues.

cause of airport flight delays

According to this data, it’s clear that late aircraft is the most prevalent cause for flight delays that ended up being longer than 15 minutes.

Late aircraft creates a domino effect: when an airplane arrives late at an airport, a following flight that uses the same aircraft will depart behind schedule. In peak months such as July, this contributes to nearly 50% of flight delays.

Worst Months of the Year to Fly

The number of flights on U.S. airlines has more than tripled, from 275 million flights in 1978 to 889 million in 2018.

Along with this, flight activity is typically highest in the summer—coinciding with July’s highest average flight delay of 76 minutes. Months in the summer followed suit, with June averaging 72 minutes per delay and August having an average delay of 71 minutes, among flights that were delayed over 15 minutes.

MonthRankAverage Delay (in minutes)
July176

April471
May570
February669
January

768
September867
March965
November1062
December1160
October1259

Perhaps surprisingly, flights in December bucked this trend. Even as a flight-heavy month, average long delays hovered around 60 minutes during the holiday season.

The 10 U.S. Airports with the Fewest Delays

By comparison, a number of airports appear to have avoided this trap. Data below shows the top airports in the U.S. with the fewest flight delays during the same time period.

#9Salt Lake CitySalt Lake City International13.3%9.7 minutes
#10Santa AnaJohn Wayne Airport-Orange County14.7%9.8 minutes

As the volume of air travel continues to climb, it is clear that some airports underperform others by a wide margin. To break the vicious cycle of delays, it will be vital for airports to get initial flights departing on time in the first place.
