At best, a lack of skepticism and critical thinking in our society will leave humanity uneducated, insipid animals. At worst, it will be the cause of our ultimate demise.
To begin, I would argue that critical thinking (disciplined thinking that is clear, rational, open-minded, and informed by evidence) is related to and facilitates the process of skepticism (the method of suspended judgment or systematic doubt). In order to be skeptical, you must be able to systematically pick apart problems with the concept or idea. By utilizing critical thinking in one’s skepticism, we can challenge fixed beliefs and continue to advance our society with scientific, artistic, social, and other pursuits. Additionally, employers strongly value critical thinking in their potential employees and critical thinking skills are positively correlated with GPA.
Despite the obvious importance of advancing mankind, some individuals are actually opposed to teaching this kind of thinking. The Republican Party of Texas’ Official Platform explicitly stated they were against the teaching of critical thinking in public school classrooms (quoted from their platform: “We oppose the teaching of… critical thinking skills”). It is astonishing that these elected politicians would even consider such a position, let alone have it in their official platform.
This certainly reflects a problem in American society with regards to the values of critical thinking and skepticism. In his book The Demon-Haunted World, Carl Sagan discusses the problem with not valuing these types of thinking in our society. He mentions that even people who may want to study science can be overwhelmed by pseudoscience, and science is “often filtered out” before it reaches us.
The fact that scientists like Sagan are critical of our scientific inadequacies would not mean much if it not for the data that backs up their statements. Americans have embarrassingly low scores in worldwide comparisons of scientific literacy, science, and math. Skepticism and critical thinking are simply not valued in American society, and the data supports it.
Because skepticism and critical thinking are not cultivated in American society, many Americans cannot tell when they encounter something that is pseudoscience (such as homeopathy or astrology). Someone may want to learn about scientific research, but due to our society’s scientific climate, people are inundated with pseudoscientific claims. Furthermore, with the advent of the internet, there is so much information about everything so you can find arguments for any position–with sound evidence or without.
However, a keen understanding of science makes it easy to determine which claims have a substantial amount of evidence. For example, climate change has been documented as a real and problematic phenomenon by many, many researchers. But a few vocal people have found “evidence” against climate change that makes people think twice–as they should when presented with conflicting data. However, any scientifically literate person should be able to see that the overwhelming evidence is that climate change is a real phenomenon and the few studies against it are outliers, poorly done, or cherry-pick data based on their biases.
These biases also impact how people deal with scientific claims in general. People may blindly follow someone who they think is in charge or an expert without analyzing things for themselves (see Milgram’s obedience study). People also see others following these “experts” and are likely to try to conform (see Asch conformity studies). When many people are already blindly following perceived authority figures, it is likely to continue because people do not want to be nonconformists, and the cycle continues. It takes more of a psychological effort to research things for oneself as it is, but couple this with a cultural environment that does not foster critical thinking, skepticism, or science, and we have a legitimate problem.
Furthermore, science in general is often misrepresented in the media. My own field of psychology is often decimated by its public representation and perception. I am technically getting a PhD in experimental psychology, but if I say the word “psychology” to an average person on the street, they think I will psychoanalyze them on a couch, read their mind (though, ironically, my research is actually like mind reading in a scientific sense), or engage in some other pseudoscientific method they saw on television. So I often tell people I study neuroscience because it has less stigma compared to psychology–though people are less likely to know what neuroscience even is!
Most other sciences deal with these issues, as well. The average American is simply not inclined to research or understand scientific concepts because skepticism and critical thinking are not valued in our society. Listening to what people say on television is often good enough for most people. It may not directly impact one person who doesn’t know what an experimental psychologist actually does, but that mindset of incessantly accepting information without challenging it can have catastrophic consequences. We are left with a critical mass of people who do not challenge information presented to them. They blindly follow what perceived authority figures tell them without a second thought.
Critical thinking allows people to dissect and analyze information, and skepticism prompts them to question the information that’s being presented to them first. So I ask, I plead, whoever is reading this–please stand up for the importance of skepticism and critical thinking. Write to your local politicians telling them about it. Do not let someone say something mindless and unfounded without challenging them. We need to foster an environment in which people feel comfortable challenging ideas and concepts. Once this happens, many more people will be thinking critically about our society’s problems and greater progress will occur.
