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 have a tendency to think in particular 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 five examples of how these types of biases can affect people in the business world:

1. 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.

2. 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.

3. 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.

4. 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.

5. Gambler’s Fallacy: A venture capitalist sees a portfolio company rise and rise in value after its IPO, far behind what he initially thought possible. Instead of holding on to a winner and rationally evaluating the possibility that appreciation could still continue, he dumps the stock to lock in the existing gains.

Visualizing the Average Lifespans of Mammals

While smaller animals such as weasels typically live 1-2 years, larger counterparts can thrive for decades.

Mammals, though comprising a small fraction of Earth’s creatures, hold vital ecological roles globally. They are crucial for maintaining ecosystem health through services like pollination, seed dispersal, and predator-prey dynamics.

In this visualization, we depict the average lifespans of mammals, using data from Discover Wildlife and the United Nations.

Human Lifespans on the Rise

Defined as warm-blooded creatures with hair or fur, mammals nurse their young with milk from mammary glands. While smaller animals such as weasels typically live 1-2 years, larger counterparts like elephants can thrive for decades, and bowhead whales can live for 200 years, or even longer.

Notably, human lifespans have experienced a remarkable surge. According to the UN Population Division, the global average life expectancy has surged from 47 years in 1950 to 72 years in 2022, marking a 25-year increase. This is attributed to advancements in nutrition, medication, and essential resources.

However, as human longevity flourishes, it can have an adverse effect on wildlife mammal populations. To put this into numbers, over the past 100,000 years, the surge in human population has precipitated an 85% reduction in wild mammal biomass.

Today, livestock dominates 62% of the world’s mammal biomass, with humans accounting for 34%, while wild mammals comprise only 4%.

Despite a decline in mammal diversity, the total biomass of terrestrial mammals has significantly increased, expanding approximately ninefold over the past 10,000 years.
