50 Cognitive Biases in the Modern World

Cognitive biases are widely accepted as something that makes us human.

Every day, systematic errors in our thought process impact the way we live and work. But in a world where everything we do is changing rapidly—from the way we store information to the way we watch TV—what really classifies as rational thinking?

It’s a question with no right or wrong answer, but to help us decide for ourselves, today’s infographic from TitleMax lists 50 cognitive biases that we may want to become privy to.

In the name of self-awareness, here’s a closer look at three recently discovered biases that we are most prone to exhibiting in the modern world.

Automation Bias

AI-infused applications are becoming incredibly good at “personalizing” our content, but will there come a time when we let algorithms make all of our decisions?

Automation bias refers to the tendency to favor the suggestions of automated systems.

Take Netflix, for example. Everything we see on the platform is the result of algorithms—even the preview images that are generated. Then, to harness the power of data and machine learning, Netflix categorizes its content into tens of thousands of micro-genres. Pairing these genre tags with a viewer’s history allows them to assign several of over 2,000 “taste profiles” to each user.

And while there’s nothing wrong with allowing Netflix to guide what we watch, there’s an enormous sea of content standing by. Estimates from 2015 claimed it would take nearly four years to watch all of Netflix’s content. Thousands more hours of content have since been added.

If we want to counter this cognitive bias, finding a new favorite series on platforms like Netflix may require some good old-fashioned human curiosity.

The Google Effect

Also known as “digital amnesia”, the aptly named Google Effect describes our tendency to forget information that can be easily accessed online.

First described in 2011 by Betsy Sparrow (Columbia University) and her colleagues, their paper described the results of several memory experiments involving technology.

In one experiment, participants typed trivia statements into a computer and were later asked to recall them. Half believed the statements were saved, and half believed the statements were erased. The results were significant: participants who assumed they could look up their statements did not make much effort to remember them.

Because search engines are continually available to us, we may often be in a state of not feeling we need to encode the information internally. When we need it, we will look it up.

– Sparrow B, et al. Science 333, 777 (2011) 

Our modern brains appear to be re-prioritizing the information we hold onto. Notably, the study doesn’t suggest we’re becoming less intelligent—our ability to learn offline remains the same.

The IKEA Effect

Identified in 2011 by Michael Norton (Harvard Business School) and his colleagues, this cognitive bias refers to our tendency to attach a higher value to things we help create.

Combining the Ikea Effect with other related traits, such as our willingness to pay a premium for customization, is a strategy employed by companies seeking to increase the intrinsic value that we attach to their products.

For instance, American retailer Build-A-Bear Workshop is anchored around creating a highly interactive customer experience. With the help of staff, children (or adults) can assemble their stuffed animals from scratch, then add clothing and accessories at extra cost.

Nike also incorporates this bias into its offering. The footwear company offers a Nike By You line of customizable products, where customers pay a premium to design bespoke shoes with an extensive online configurator.

While there’s nothing necessarily wrong with our susceptibility to the Ikea Effect, understanding its significance may help us make more appropriate decisions as consumers.

What Can We Do?

As we navigate an increasingly complex world, it’s natural for us to unconsciously adopt new patterns of behavior.

Becoming aware of our cognitive biases, and their implications, can help us stay on the right course.

Interactive: Comparing Military Spend Around the World

Which countries have the highest military spend relative to their economy? This visual breaks down the amount spent in each country by GDP.



A map showing countries' military spend as a percentage of their gross domestic product.

Comparing Military Spend Around the World

One of the easiest ways to identify a nation’s priorities is by tracking its expenditures, and military spend is no different.

Usually spending is measured, and ranked, in absolute amounts. For example, countries around the world collectively spent $2.1 trillion on their militaries in 2021, with the most coming from the U.S. ($800 billion), China ($293 billion), and India ($77 billion).

But these eye-popping figures are best understood in the context of each country’s economy. Using data from the Stockholm International Peace Research Institute (SIPRI), Varun Jain has visualized 158 countries’ military expenditures, both as a percentage of their total GDP as well as in average per-capita spend.

Countries’ Military Spend as a Percentage of their Economy

To begin, Jain identified three categories of military expenditure as a percent of GDP, using the five-year (2018‒2022) average for more consistent data:

Military Spend% of GDPCountries
HighAbove 5%7
LowBelow 2%107

Under this categorization, the stand outs are the countries spending an outsized amount of their economic output on military, rather than the highest total spenders in absolute terms.

At the top of the table is Ukraine, which has earmarked a staggering average of 9.46% of its total economic output on defense over the past five years. That’s well ahead of second-place Saudi Arabia, which is slightly above 8%.

In Ukraine’s case, its high ranking shows how quickly priorities can change. From 2018 to 2021, the country spent 3.2-3.8% of its GDP on its military, but the outbreak of war with Russia saw its expenditures jump to one-third of economic output.

Other countries from the Middle East and North Africa follow in this tier, with Oman third at 8.11% and Qatar fourth with 5.88%. Rounding out the top seven high spenders are Algeria, Kuwait, and Israel.

The medium group consists of 44 countries and is led by four nations (Jordan, Armenia, Azerbaijan, and Lebanon) that all spend more than 4% of their GDP on their militaries. Other familiar countries known to have large military budgets, like Russia, Pakistan, the U.S., India and the UK, are also in this category.

The low spend group has a total of 107 countries, but also contains some surprises. For example, China, France, and Germany—all in the top 10 countries by absolute military spend—actually have similar amounts of military spend as a percent of GDP as Georgia, Cyprus, and North Macedonia respectively.

At the bottom of the table are countries with either low military importance, or strange technicalities. For example, Mauritius is one of the countries with the lowest military budgets because it doesn’t officially have a standing military, instead relying on two paramilitary forces (a special mobile force and a Coast Guard).

Similarly, Iceland allocates 0% of its GDP towards military spending. In place of a standing army, the country maintains a specialized peacekeeping force, a substantial Coast Guard, and relies on security alliances within NATO, of which it is a member and provides financial support to.

Ranking Defense Spending Per Capita

While the measure above equalizes military spend on economic strength, per-capita military spending shows how much countries allocate while accounting for population size.

On a per-capita basis (again using a five-year average), Qatar leads the ranks with a per-capita spend of $4,564, well-ahead of Israel at $2,535, and Saudi Arabia at $1,928.

Measured this way, we get a perspective of how small defense budgets can be per person, even if the total expenditure is large.

For example, India has the fourth-highest total defense expenditure in 2022, but because of its massive population only sets aside $53 per resident for its military, putting it solidly at the bottom third of the per-capita rankings.

Patterns Revealed By Measuring Military Spend

Changing how we look at a country’s military budget can reveal a lot more than just looking at absolute numbers.

For example, the Middle East is the region with the highest spenders on defense as a percentage of their GDP, giving us insight into regional security concerns.

Countries from the medium group of military spending—including parts of Eastern Europe, sub-Saharan Africa, and South Asia—highlight past or recent conflict zones between neighbors, countries with internal strife, or countries wary of a regional aggressor. Ukraine’s average per capita military spend, for example, was just $122.4 from 2018 to 2021. The next year, it jumped nearly 10 times to $1,018.66 per person after Russia’s invasion.

In fact, European military spending saw its sharpest one-year jump in 30 years as a direct result of the war.

Alongside European anxieties, ongoing tension between China and Taiwan has also contributed to increased military spending in Asia and Oceania. Will these budgets continue their dramatic ascent or will they rise evenly alongside their relative economies in 2023?

Data note: For these comparisons, the creator is calculating five-year averages (using data from 2018-2022) for military spending as a percentage of GDP and per-capita military spending for each country. The military expenditure data is pulled from Stockholm International Peace Research Institute.

Data for some countries is missing or may vary significantly from official figures. Countries with up to
two years of missing data had averages calculated on the years available, while countries with three or more years of missing data have been removed from this dataset, including: Djibouti, Eritrea, North Korea, Laos, Libya, Somalia, Syria, Turkmenistan, UAE, and Yemen.

Please see SIPRI’s methodologies page for more details on how they collect their data and create estimates.
