You may think that scrolling endlessly through social media is a harmless way to decompress after a long day of work and let your mind relax. And the latest research on the mental and emotional effects of sinking hours into social media suggests that it has a relatively limited effect on your well-being.
While social media may not be the cause for the increasing youth depression rates, it does have a perhaps, more insidious effect on our critical thinking skills. The average adult spends 2 hours and 24 minutes every day on social media. It’s impossible to spend that much time doing a single activity in your day without the repetitive behaviors associated with that activity carrying over into how you do other activities.
How Social Media is Undermining Your Critical Thinking Skills
Said another way, the way you engage with social media is, likely without you knowing it, training you how to think when at work, when interacting with friends and family, and when running into strangers on the street. Patricia Greenfield, UCLA distinguished professor of psychology and director of the Children’s Digital Media Center in Los Angeles, puts it this way: “the mid-21st century mind might almost be infantilized, characterized by short attention spans, sensationalism, inability to empathize and a shaky sense of identity.”
When you thumb through Instagram or Twitter posts, you’re building cognitive habits around how you process and make sense of information. And research suggests that our habits for processing information on social media are far from exemplary. We know this because many people fail to identify fake or false information from true information. In one study, 44% of millennial participants failed to correctly identify whether information was true or false in at least four of nine questions.
The more time people spend on social media, the more likely they are to fall prey to false information. A study sponsored by the Reboot Foundation found that 36% of people who check social media hourly or more frequently held at least one wrong belief about COVID-19, while only 22% of people who checked social media once a week held at least one wrong belief.
Our use of social media limits the development of robust critical thinking skills. Professor Greenfield explains that the visual media we consume on screens “do not allow time for reflection, analysis or imagination — those do not get developed by real-time media such as television or video games.”
While identifying fake news is a key critical thinking-related challenge when it comes to social media, there is another challenge that goes beyond deciphering fact from fake. This is the challenge of determining whether the reasoning that underlies a post or article is rigorous and rationale. Unfortunately, social media is littered with posts that contain critical thinking fallacies. We must learn to identify them or we will fall prey to them not just on social media, but in every area of life.
Here are some examples of common critical thinking fallacies.
Examples of Critical Thinking Fallacies on Social Media
Our goal is not to convince you of any particular point of view found in the examples. Critical thinking doesn’t care about the answer. It only cares about the rigor behind the support for the answer. As we’ve explained, critical thinking is providing a robust answer to a question.
Undermining the Messenger Fallacy:
Many times, people on social media immediately dismiss an idea because of the person sharing it. This is a cognitive shortcut that leads to lazy thinking. There is no law of logic or nature that dictates that if people made statements that are wrong or false in the past, they can no longer make any statements that are right or true.
When you discredit ideas because of their source, you operate out of “stereotype thinking.” Stereotype thinking says that because a certain condition has been statistically probable in the past, it is true in the present. While stereotypes can help people make snap decisions when absolutely necessary, they create significant problems as we can clearly see from the stories of racial inequity that are becoming more visible.
Because most people fall prey to this fallacy, those arguing on social media often resort to a cheap and often irrelevant strategy for dismissing the ideas of those with whom they disagree. Rather than engaging in a debate around the idea shared by their opponent, they simply hurl personal attacks at the opponent. The goal is to discredit the messenger so that we will automatically dismiss the idea.
Here’s a simple, but common example:
@JoeBiden, you & your son Hunter are #MadeInChina pic.twitter.com/0Z3eSM0Bpp— Marla Hohner (@marlahohner) July 1, 2020
The other consequence of this fallacy is that we are much more likely to reject an idea posed by someone we dislike even if we would have supported the idea had it been presented by someone we like – and the opposite is true, we are quick to support ideas shared by our friends even if they aren’t rigorous enough to warrant our support.
Correlation vs. Causation Fallacy
This is a more well-known fallacy that is beat into the head of every statistics student: correlation doesn’t mean causation. Just because two events trend together doesn’t mean that one caused the other. For example, let’s imagine hypothetically that you found data asserting that people drive slower in urban areas when it rains. The conclusion that most people would jump to is that the presence of rain causes people to drive more slowly. If your job is to eliminate the slow-downs, you might try to solve this problem by requiring drivers to go through rain driving training or increasing regulations on tire conditions during vehicle inspections.
However, it’s easy to see that a third factor may be the cause of reduced driving speeds. When it rains, more people in cities are likely to drive (rather than walk, bike, or take public transport and get wet), creating more traffic, which, in turn, could cause people to drive more slowly.
You can see how the tendency to believe that correlation equals causation can cause you to arrive at very different conclusions.
Why don’t you just save time by saying:— Bad Panda 428 (@428Panda) July 1, 2020
ALL Cities run by @TheDemocrats are GONE!
George Floyd died in Minneapolis, with:
DEMOCRAT City Council
But it’s @realDonaldTrump’s fault and let’s defund the Police!
The logic used in this Twitter thread is that Democrats are the cause for riots and racist police brutality because the leadership in those cities and states are largely Democratic. While this could be the case, the data shared in this tweet only establishes correlation, not causation. There are many other possible explanations for how both of these facts can be true without one causing the other.

Wrong Denominator Fallacy
Dividing the incidence of an event by a denominator helps achieve what statisticians call normalization of the data. For example, imagine you take a test that has 200 questions and you get 20 wrong and your friend takes a test with 100 questions and gets 11 wrong. If you simply compare the number of wrong answers, you would think you did worse. But you answered more questions than your friend, so you have to divide the number wrong by the total number of questions:
- 20/200 = 10% wrong
- 11/100 = 11% wrong
When you normalize the data by dividing by the right denominator, you can see the that conclusion is reversed: you did better, not worse.
Sometimes people run into critical thinking fallacies because they don’t normalize the data; that is, they don’t divide by a denominator. But a more subtle fallacy is dividing by the wrong denominator.
