These days, in our ever complex society, it's becoming increasingly important to be able to think critically, in particular with young minds that can be easily molded. Understanding cognitive biases, logical fallacies and mental models at an early age may well give them and us the hope of a better and brighter future. The Decision-Making Blueprint by Patrik Edblad lists 45 of these important tools, though I will only focus on several that young learners in particular struggle with.
The status quo bias and the homeostasis model work hand in hand with many students. The status quo bias is the tendency to prefer things stay the same, while homeostasis is the state of a system that wants to maintain internal stability. For example, kids who say they don't like art or PE or math, continue to maintain that viewpoint. This could have come about because of confirmation bias, where people tend to favor information that confirms their existing beliefs. So if a student does poorly on a math quiz, that confirms the "fact" that they are poor at math. All of these ways of thinking run counter to the growth mindset, where effort and dedication will lead to success, which is what teachers try to instill in learners. Connected to this idea is that of compounding. Most kids have trouble seeing too far into their future, but modest gains on a daily or weekly basis can achieve dramatic results, according to James Clear, author of Atomic Habits. If you memorize your times tables 5 minutes, 3 times a week, for one week, the results might be negligible. However, if you maintain that for a whole year, then you will probably memorize them quite easily.
In some cases, students suffer from the Dunning-Kruger Effect, which is the tendency to be more confident the less you know. "If you're incompetent, you can't know you're incompetent," says David Dunning. I think the simple graphic organizer, K-W-L, helps visualize the gaps in learning. Also, the W, which represents "want" is critical. What do students want to learn? Curiosity is one of the main bulwarks to remaining ignorant or incompetent.
Young kids also suffer from self-serving bias. For example, if a student gets a good mark, it's because of their effort or intelligence, but if they do poorly, it's because of the tough teacher or unfair tests. This goes hand-in-hand with the fundamental attribution error: when someone else makes a mistake, it's their fault entirely, but when you make an error, it's due to circumstance. A classic example would be if you hit a student in the head with a dodgeball; it was an accident and the ball slipped out of your hand or they ducked at the inopportune time. But if they hit you in the head, it was intentional and mean-spirited. This aptly segways into Hanlon's Razor (a subset of Occam's Razor), which is to never attribute to malice what can be explained by neglect. However, when you listen to countless arguments between kids, this is often the mental model that they base their thinking on. In addition, the availability bias, is a contributing factor--basing our judgments on what easily comes to mind. Kids (along with adults) often keep a mental record of all the wrongs done to them. Instead of a pattern of behavior, Hanlon's Razor would treat each as an isolated occurrence.
The 80/20 Principle, developed by Italian economist Vilfredo Pareto in the late 1800s, has proven to be a valuable principle today--essentially that 80% of the effects come from 20% of the causes. It would be wise and valuable to figure out what that 20% is in the classroom, which would result in 80% of the learning. It could be the basics of the curriculum--reading, writing and math; or it could be instilling curiosity, hard work, passion, self-directed learning, and the growth mindset. Or maybe which 20% of the students need the most support. Or something entirely different in another classroom.
On a final note, of course there are caveats for all of these biases, logical fallacies and mental models. Sometimes the opposite can be true. They are not 100% accurate all the time, so treat them as principles or guidelines, not laws or commandments.
