“If you judge a man, do you judge him when he is wrapped in a disguise?”
Seneca (4 BC – 65 AD)
The mind has a few habits that we should pay attention to when we are trying to maximize our learning. Everyone is susceptible to these thought patterns and it would be advantageous to find where these patterns occur within our own lives. Without understanding these habits we could subconsciously close ourselves off to information that could be important to our education. I like to refer to these habits of the mind as Cognitive Biases. Officially, they can be thought of as systematic errors in thinking as a result of subjective perception. Cognitive Biases act as filters between us and the outside world. We view the world through whichever lense our minds naturally applies to a situation. If we don’t see the world objectively, then we see the world through our biases and that can prevent us from learning information that we don’t know we need. Understanding our cognitive biases, or unconscious filters, is our best shot at keeping them at bay so we can be best prepared for the worst that Fortuna has to throw at us. (I’ve been reading a lot of stoic philosophers recently)
Understanding these biases helps with critical thinking development. We all have biases and it’s difficult, maybe impossible, to remove them completely, but we can develop more reliable ways of learning through our bias. This could be achieved through seeking out people who will challenge and critique our ideas. Not learning about our own biases will keep us in a bubble. Our minds will filter out important information because we believe it to be useless. Through understanding our biases of the world and ourselves, our education falls into our control rather than having our minds unconsciously run the show.

Types of Cognitive Bias
Below are a few examples of cognitive biases that, if understood well, could help us maximize our learning and make our minds an ally rather than an enemy:
Disconfirmation Principle
This principle describe the phenomena where people tend to accept new information that support their already held beliefs, and are more likely to refuse new information that challenge their beliefs.
I try to pay attention to any current beliefs that I have now and what new information I quickly reject because it doesn’t align with my beliefs. Just because something supports what we already believe doesn’t mean it’s true or that it will help us. It’s important for us to do a detached analysis of all the information we are presented with. Its healthy to keep a small degree of skepticism, but it’s useful to consider that we may just be dismissing something simply because we don’t agree.
Confirmation Bias
This describes the tendency to interpret new information as evidence to support your already existing beliefs.
This is different than disconfirmation principle. Confirmation bias is saying that we will look at information and try to make it support our already held beliefs. This is dangerous because it can lead to overconfidence and overconfidence can tank our test scores and lead us to make terrible decisions. The overconfidence comes from seeing constant validations everywhere we go. Thinking that everything supports our ideas can delude us into thinking that we always come to correct conclusions. It is important to be aware of this “mind habit” and remain objective, as we can be, when obtaining new knowledge.
Belief Preservation
The tendency to keep believing an initial belief even after receiving new information that contradicts or disproves the initial belief.
This reminds me of a mentally ill patient I once had who honestly thought the sky was green. When we took her outside, she saw that the sky was grey (it was raining that day) and refused to believe that the sky wasn’t green. Now it’s easy to think that since she’s not completely alert and oriented, she’s not going to follow the same conventions as everyone else but even if we are open minded, we have a natural tendency to keep holding on to our beliefs even if everything around us tells us we‘re wrong. The best way to prevent belief preservation from hindering our growth is to recognize it’s there when it comes up and try to look at new information regardless of your personal feelings.
Conviction Bias
This bias is best summed up with the statement “I believe it strongly, so it must be true.”
We are so strongly captured by some of our beliefs that we mistake them to be truth. In order to remain open, we must constantly question the beliefs we tend to hold as truths. (I do think a little too often sometimes and wonder if I’m crazy but there is an optimal balance to be achieved) We cannot become too attached to our beliefs. Who we are and what we believe do not have to be the same thing. Learning something to be false that we believe so strongly has a punishing feel and has consequences deeper than we can see. It’s totally possible to be so rooted in our ways that we sacrifice who we could be for who we are.
Appearance Bias
This has less to do with incoming information and more to do with people that we encounter. This bias describes the assumption that we know and understand the people that we deal with and that we see them for who we are.
It is important to understand that we do not see people for who there are, but we see them as they appear to us. It’s a great piece of knowledge to bring with you throughout life but can also bring us success in the academic world. Do not think that you know a teacher, or a professor, or a student based on what you can see. Everyone is just as, or even more, complicated as you. Keep an open mind and notice when you start to think that you have someone figured out. They may know something you don’t and that knowledge may bring you incredible insights into the world. In order to maintain a grip on my appearance bias, I try to listen to people as if they always have something they can teach me.
Group Bias
This is regarding the lie we tell ourselves when we are in groups; we have our own ideas and don’t listen to the opinions of a group. Within a group, our thoughts are rarely our own, but are of the group and its very likely that the group will come to a conclusion that is incorrect. We are social creature and NEED to conform. This is the basis for groupthink and group polarization and can lead to dangerous outcomes. This is not to say that group work isn’t great. We can get far more done as a group than as an individual, but that trade isn’t for free. We sacrifice a bit of autonomy and individualized thinking.
Group bias is something we should look out for when we are group studying or working on group projects. Make sure that the group does not lead you astray by learning incorrect information. Its very easy to think that you understand a concept because you understand how the group looks at it, but it’s very possible that everyone in the group is incorrect. Group bias and confirmation bias can be a deadly combination, I learned this lesson the hard way when I took Physical Chemistry at Cal State Long Beach. I studied with a group and we all thought we understood what was going on, but we all ended up failing the test.
Blame Bias
The idea that we pretend that we learn from our mistakes but actually hate to look at our imperfections closely, which limits our ability for introspection and reflection.
Learning from our mistakes is usually the best way to learn anything but keep in mind that we cannot learn from our mistakes all on our own. It’s best to look to someone who knows more about your endeavor so they can help you explore why you made those mistakes in the first place. We all have blind spots and we need others to help us see them. We are a social creature after all! Additionally, being aware of this bias allows you to have a slightly deeper insight into your errors than you naturally would have.
Superiority Bias
The idea that we believe that we are different, more rational, and more ethical than other people.
Most people probably wouldn’t say this out loud but deep down we believe it. This is why we get so upset when we see other people make dumb mistakes or think “everyone else” is so terrible. It is important to keep in mind that we are more similar to other people than different and pitfalls that most people can fall into are probably a danger to us as well. Everyone believes that they are smart, capable, independent, and good. Keep in mind that you are not as superior as you might think and you will go very far in life and in learning. Humility removes a lot of unnecessary friction and coming to terms with our own delusions of grandiosity helps with our progress.
Fundamental Attribution Error (FAE)
When we attribute other people’s errors to internal factors, and our own errors to external factors.
An example of this would be when someone cuts you off while driving. It’s easy to think that they cut you off because they are a terrible person. But if you were the one who would have cut them off, it would have been because “you had to” or “you were in a rush” and it’s not because you are bad person. FAE is a type of Self-Serving Bias, which are a set of biases that protect our self esteem or where we see ourselves in an overly favorable manner. Knowing this can help you be more patient with others and you can catch yourself when you start to think that one of your mistakes may be due to outside circumstances.
Neglect of Probability
The tendency to disregard probability when making a decision under uncertainty.
During my time in school I’ve always wondered why I had to learn something and didn’t bother learning a lot of it because I figured that most of that information would never come up. Turns out, I used more of it than I expected, like all the advanced math I use daily because I’m a math tutor. When we’re presented with new information we make a choice to learn it based on if we think it will be useful to us in the future, but this bias demonstrates that we naturally disregard actual the probability that it can come up again. It’s difficult to predict if it will come up at all and if we knew the probability, chances are we’d ignore the raw data and believe what makes feel good. This is true not just with learning but with many of the decisions of our lives. We should try to think about how often we may need the information we may learn and not be satisfied with a surface level analysis or even with what other people will tell us. Academic topics taught earlier on are taught for a reason and topics later will very likely build upon the assumption that you proficiently learned all of the topics prior, and the answers to the problems of life require a sophisticated synthesis of all the information you’ve been exposed to and internalized.
Availability Heuristic
We determine how likely something is by how easily we can recall events of it happening in our brain.
An example of this would be a medical assistant who is working in a stroke center believes that strokes occur more often than they actually do because they can remember many instances when someone had a stroke. Another could be a psychiatrist who specializes in ADHD can easily view a patient’s pathologies and conclude ADHD because they believe it is highly probable that the patient has ADHD, but the psychiatrist only believes that ADHD is highly probable because he can recall many events of people having ADHD. Just because we can recall an event easily, doesn’t mean it has a high probability of occuring often.
Dunning-Kruger Effect
This is a theory that suggests people tend to believe their cognitive ability is higher than it actually is.
My explanation above suggests the relationship between knowledge and perceived ability is linear but it’s more nuanced. As we learn more about a subject, our perceptions adjust from the initial ignorant and confident position following the graph below. I love graphs because they explain concepts better than I can with words.

Priming Bias
Our tendency to be included by what someone else as said or made to create a preconceived idea.
This happens to me all the time with meal ideas. Someone will mention an In-N-Out double double in a conversation and a few hours later if someone else asks me what I want to eat, I’ll say I want a double double from In-N-Out and I will have completely believed this was my own idea. This is a big reason why I try to limit my social media use, I don’t like the idea that my thoughts could be decided by someone else’s poorly thought-through comment or that the standards for my life and myself could be created by other people’s standards. Our ideas aren’t always our own, and it’s useful to recognize that.
Hindsight Bias
Also known as the “I-knew-it-all-along” effect which is our tendency to see events in the past as highly predictable.
Hindsight is 20/20 and it’s easy to wonder why we didn’t act differently when we were younger. “Last year, I couldn’t have even fathom the depths of my ignorance” is the phrase I’m telling myself every year and I tend to be a harsh judge of younger Chris’ choices. The truth is, in the present moment it’s difficult to know which is the path most aligned with our Jungian Self. When we reflect back on our decisions, it’s important to keep that in mind that our past selves were trying to make the best choices they could at the time, unless you know they weren’t. Hindsight bias makes the past make sense and with the knowledge comes a harsh judgment on our past selves. Hindsight bias gets in the way of compassion for yourself and can distort your narrative. Watch it closely, we never really knew it all along.
A big part of managing cognitive biases is taking a little extra time to recognize the patterns and reevaluating what we really think about something. Cognitive biases are strong forces in the mind, but we can overcome them by taking a little time and slowing down.
There are a huge number of cognitive biases that can help you with your learning and life in general and I recommend taking time to learn more of them. These were just a few of the biases that I have found relevant to student success and my own life. Understanding these biases, or “mind habits,” will give us power over our natural tendencies to filter information. Be aware of them when they come up and approach all new knowledge with an open mindset and healthy skepticism.
