In a world of information overload, we can fall victim to all sorts of cognitive biases. Since they can lead us to generate false conclusions, it’s particularly important to understand what these biases are and how they work, as the consequences can become quite drastic.
Confirmation bias, sampling bias, and brilliance bias are three examples that can affect our ability to critically engage with information. Jono Hey of Sketchplanations walks us through these cognitive bias examples, to help us better understand how they influence our day-to-day lives.
One of the most-commonly encountered and understood, you’re likely to have already heard about confirmation bias. This cognitive bias affects the way we test and evaluate hypotheses every day.
In simple terms, confirmation bias is the tendency to seek out or interpret evidence in such a way that supports our own strongly-held beliefs or expectations. This means that, given access to the same set of data and information, different people can come to wildly differing conclusions.
Feeding into confirmation bias can lead us to make ill-informed choices or even reinforce negative stereotypes. For this reason, it is important to remember to seek out information that both confirms and contradicts your presumptions about a certain topic.
Sampling bias is a kind of bias that allows us to come to faulty conclusions based on inaccurate sample groups or data. Generally, the cause of sample bias is in poor study design and data collection.
When polling individuals for survey questions, it is important to get a representative picture of an entire population. But this can prove surprisingly difficult when the people generating the study are also prone to human flaws, including cognitive biases.
A common example involves conducting a survey on which political party is likely to win an election. If the study is run by a professor who only polls college students, since they are around and therefore easier to collect information from, the poll will not accurately reflect the opinions of the general population.
To avoid sampling bias, it is important to randomize data collection to ensure responses are not skewed towards individuals with similar characteristics.
Brilliance bias is another common cognitive bias that makes us more likely to think of genius as a masculine trait. This is in part due to the lack of female representation in both traditional academic and executive positions.
In fact, The Journal of Experimental Social Psychology published an in-depth study on brilliance bias in 2020. It suggests that a likely source of this bias is in the uneven distribution of men and women across careers typically associated with higher level intelligence.
While this distribution is a remnant of historical factors that limited access to education and career choices for women in the past, its presence has made us (wrongly) conclude that women are less brilliant instead. Naturally, as the cycle perpetuates the uneven distribution of women in these careers, it only reinforces this bias.
Other Cognitive Bias Examples
These few examples from Jono Hey give a good overview of some of the biases we face when trying to understand the data given to us, but they are just the tip of the iceberg.
It is important to be cognizant of these biases in an era where we are constantly engaging with information, especially if we want to combat some of the harmful consequences they entail.

*Inflation rates based on the latest available data.
As price pressures mount, 33 central banks tracked by the Bank of International Settlements (out of a total of 38) have raised interest rates this year. These coordinated rate hikes are the largest in two decades, representing an end to an era of rock-bottom interest rates.
Going into 2023, central banks could continue this shift towards hawkish policies as inflation remains aggressively high.
The Role of Energy Prices
Driven by the war in Ukraine, energy inflation is pushing up the cost of living around the world.
Since October 2020, an index of global energy prices—made up of crude oil, natural gas, coal, and propane—has increased drastically.
Compared to the 2021 average, natural gas prices in Europe are up sixfold. Real European household electricity prices are up 78% and gas prices have climbed even more, at 144% compared to 20-year averages.
Amid global competition for liquefied natural gas supplies, price pressures are likely to stay high, even though they have fallen recently. Other harmful consequences of the energy shock include price volatility, economic strain, and energy shortages.
“The world is in the midst of the first truly global energy crisis, with impacts that will be felt for years to come”.
-Fatih Birol, executive director of the IEA
Double-Digit Inflation: Will it Last?
If history is an example, taming rising prices could take at least a few years yet.
Take the sky-high inflation of the 1980s. Italy, which managed to combat inflation faster than most countries, brought down inflation from 22% in 1980 to 4% in 1986.
If global inflation rates, which hover around 9.8% in 2022, were to follow this course, it would take at least until 2025 for levels to reach the 2% target.
It’s worth noting that inflation was also highly volatile over this decade. Consider how inflation fell across much of the rich world by 1981 but shot up again in 1987 amid higher energy prices. Federal Reserve chair Jerome Powell spoke to the volatility of inflation at their November meeting, indicating that high inflation has a chance of following a period of low inflation.
While the Federal Reserve projects U.S. inflation to fall closer to its 2% target by 2024, the road ahead could still get a lot bumpier between now and then.
Visualized: The Many Shapes of Bacteria
We introduce the visual diversity of bacteria and illustrate how they are categorized by appearance—from a single cell to an entire colony.
Invisible Diversity: The Many Shapes of Bacteria
Bacteria are amazing.
They were the first form of life to appear on Earth almost 3.8 billion years ago.
They make up the second most abundant lifeform, only outweighed by plants.
And most interesting of all: they exist in practically every environment on our planet, including areas where no other lifeforms can survive. As a result, bacteria exhibit a wide variety of appearances, behaviors, and applications similar to the lifeforms we see in our everyday lives.
The incredible diversity of bacteria goes underappreciated simply because they are invisible to the naked eye. Here, we illustrate how researchers classify these creatures on the basis of appearance, giving you a glimpse into this microscopic world.
A Life of Culture
Though bacteria may look similar to other microorganisms like fungi or plankton, they are entirely unique on a microscopic and genetic level.
Bacteria make up one of the three main domains of life. All life shares its earliest ancestor with this group of microbes, alongside two other domains: the Archaea and the Eukarya.
Archaea are very similar to bacteria, but have different contents making up their cell walls.
Eukarya largely consists of complex, multicellular life, like fungi, plants, and animals. Bacteria are similar to its single-celled members because all bacteria are also unicellular. However, while all Eukarya have nuclear membranes that store genetic material, bacteria do not.
Bacteria have their genetic material free-floating within their cellular bodies. This impacts how their genes are encoded, how proteins are synthesized, and how they reproduce. For example, bacteria do not reproduce sexually. Instead, they reproduce on their own.
Bacteria undergo a process called binary fission, where any one cell divides into two identical cells, and so on. Fission occurs quickly. In minutes, populations can double rapidly, eventually forming a community of genetically identical microbes called a colony.
Colonies can be visible to the human eye and can take on a variety of different shapes, textures, sizes, colors, and behaviors. You might be familiar with some of these:
Superstars of a Tiny World
The following are some interesting bacterial species, some of which you may be familiar with:
This species is unusually large, ranging from 200-700 micrometers in length. They are also incredible picky, living only within the guts of sturgeon, a type of large fish.
D. radiodurans is a coccus-shaped species that can withstand 1,500 times the dose of radiation that a human can.
Despite being known famously for poisoning food and agriculture spaces from time to time, not all E.coli species are dangerous.
Down in the depths of a South African gold mine, this species thrives without oxygen, sunlight, or friends—it is the only living species in its ecosystem. It survives eating minerals in the surrounding rock.
Known for causing stomach ulcers, this spiral-shaped species has also been associated with many cancers that impact the lymphoid tissue.
Most living things cease to survive in cold temperatures, but P. halocryophillus thrives in permafrost in the High Arctic where temperatures can drop below -25°C/-12°F.
‘Bact’ to the Future
Despite their microscopic size, the contributions bacteria make to our daily lives are enormous. Researchers everyday are using them to study new environments, create new drug therapies, and even build new materials.
Scientists can profile the diversity of species living in a habitat by extracting DNA from an environmental sample. Known as metagenomics, this field of genetics commonly studies bacterial populations.
In oxygen-free habitats, bacteria continuously find alternative sources of energy. Some have even evolved to eat plastic or metal that have been discarded in the ocean.
The healthcare industry uses bacteria to help create antibiotics, vaccines, and other metabolic products. They also play a major role in a new line of self-building materials, which include “self-healing” concrete and “living bricks”.
Those are just a few of the many examples in which bacteria impact our daily lives. Although they are invisible, without them, our world would undoubtedly look like a much different place.
