Terrible instructor. He can't teach very well. I learned nothing from him, only from tutors. His exams are ridiculous. He grades by top 50% of the class will get a B. The class average was a 62% but 50% got Bs, the rest Failed the class.

Terrible person who will do anything to make sure a student does not earn an A. Finals are impossible with stuff on their that he never covers. Miserable class!!

Awful professor. He goes on random tangents and doesnt explain anything. He seems to know a lot but cant communicate the knowledge to anyone. He's like a robot. If you can avoid taking this class with him, do it. Try online or at a different school. He just doesnt care. By far the worst class/professor I've ever had.

There's a lot of information and formulas to memorize and review each week. Do ALL of the homework. The textbook gives the answers, with work shown, so you shouldn't have any excuses. Study problems from the hw or previous day for the quizzes, they're usually similar. Study weeks before the midterm and final! GO TO THE TA HELP ROOM

Are you bored with how easy college classes are? Think it's absurd everyone doesn't have a 3.5 GPA? I mean OBVIOUSLY they just don't work as hard as you. OH, wait, people can have memorization and not be lazy? HA. Know what, tell me why, how, or what makes a stats formula work. You can't? Right. Here: Prob (HAUGluv just how much you suck

WORST TEACHER EVER. He gives quiz at every beginning of the class so don't be late, but even if you go to class and pay attention you will still miss most of quiz points because they are very difficult and he only teach some nonsense during the class. If you have a chance DO NOT choose this guy, save yourself.

His lectures are not interesting, and he will go off topic most of the time. He used to be in Law school and LOVES talking about Law; however, you must go to lecture since there is a quiz every class. Quizzes are mostly memorizing formulas and guessing what he wants you to answer. Only good thing about this class is that there is never homework.

AVOID THIS PROFESSOR IF YOU CAN!!!! he is useless in class, has impossible expectations of his students, and will threaten you with academic misconduct if you ask him for help as he believes that you should not be asking him for help since you should have either read his syllabus better or learned better.

Terrible teacher. Not clear at all what he is teaching. Goes off topic and doesn't actually teach you what to do. Gives you a ton of case studies then expects you to understand how to actually do the problem on the final. Also you only take the final, no other tests. Not helpful at all.

Not good.

I liked the fact that Mr. Haug teaches you to learn the material outside of class and prepares you for your future career. However, I also want to be successful and pass his class. I worked my butt off for this class, went to SI instructions, went to his office hours( not helpful), etc, and none of it paid off, and ended up with a C.

AWFUL instructor. Takes a philosophical approach to teaching statistics- hardly teaches necessary formulas. A novel about being "the-best-version-of-yourself" was assigned instead of a textbook. Quizzes and final are a combination of actual statistics he never taught us and metaphysical questions. Went into the final with an 83%, came out with a D.

Worst professor. I went into the final with a guaranteed C and thought I'd end up with at least a B but NOPE. I took AP Stats in high school so I came into the class with a background in the class and it helped somewhat. I studied the previous lecture beforehand for the quiz and it helped. Haug wastes his time during lecture with pointless stories.

Lectures for an hour in an ambiguous abstract fashion over a simple core concept that takes minutes to explain if he ever cared to teach the concept. Don't expect to learn from lecture. Preparing for quizzes is a guessing game. Final was ridiculous. Really smart guy, should not be teaching.

Haug is obviously a smart guy, but a professor is the last thing he should be. He philosophically babbles in lectures that are hard to follow and take notes to. Also, the quizzes he gives are impossible to study for and are meant to trick you. He needs to spend less time trying to inspire and more time teach the concepts of INTRODUCTORY stats.

Lectures are hard to follow. No notes given online. No textbook TA's are not helpful He isn't helpful during office hours and he wouldn't make an appointment with me outside of office hours. The syllabus is unclear so make sure you read the fine print. He's not a good teacher and doesn't seem to care about his students.

Mark is a very smart person but his teaching is confusing, he often talks about things irrelevant to just learning the formulas.

Beware this guy will accuse you of cheating . He has more than 85% of all the Academic Misconduct charges in the entire School of Business, almost all coming from DSCI202, Ask the Dean of the Business school or Andy Fost, the custodian of Public Records at KU. Take the summer school session or Get at DSCI degree at Rockhurst

Ive taken two classes from this guy and he is equal parts genius and sadist. He is not a good instructor. No text book only his Power Point slides. During Lecture he will call out a name then ask a question, he'll belittle your answers, he thinks it is Socratic, it just him being a bully.

DSCI202 is an ENTRY LEVEL business stats class. Haug treats it like its his PHD thesis defense. Take a JuCo class somewhere else and transfer it in. Quiz every lecture period. Lectures are off the wall material. No text Book, Hes no help during office hours. TAs are your best shot of passing. Grading comes down to Final which is really hard.

Haug might be smart but he's a terrible lecturer. Use the TAs during the lab. Go to class, keep your quizzes to study from. He is no help during office hours.

No text Book, Quiz every class, I only had 2 homework / lab assignments. Use TA in lab to ask questions. If you ask ?'s during class you get heightened observation during quizzes and Final. Take Stats at a JuCo.

Grading: mainly quizzes a couple of homework problems (3) and the final (30% of grade). You can accumulate enough extra credit points to have an A going into the final. All you need is a 13/20 on the Final to get a B, if you have maxed out the quizzes and homework. Very few people get a good grade in the class. Some ? on final were never covered.

Lectures and quizzes every period, Final is a beast. No text book, so self-study is a challenge. Think of it as a Metaphysical Stats class. His lectures are just confusing. I tried 3 times for an appointment during office hours & struck out. Pay attention to fine print in Syllabus.

Most demeaning prof I've ever had. He lets his view of the world interfere with teaching a basic stats class. If you can take something from the Math dept. instead of this class, do it, that use to be an option in KU B-school, I'd ask. No text book, only electronic slides. TAs are not helpful. He is too busy to keep office hours.

I would never take another class from this guy. He is probably the main reason KU cannot get a Decision Science degree program off the ground. I voted with my feet and am currently getting a Masters in Decision Science from Rockhurst College In Kansas City.

Quiz almost every Class. Lectures are a mix of intro to stats and his ideas about life. He's is kind of Cultish with his TA's so be careful asking questions in Discussion period.

Instructor is a Dr, Moonbeam candidate. get another instructor if you can

This is a basic stats class, with a prof that needs some serious help in his teaching methods. Subject matter is straight forward, but he wants you to put his PC spin on it and how you approach the work.

Intro stats class, Haug makes it incomprehensible with his teaching style. take it somewhere else and transfer in.

class has a stated purpose and he is very enthusiastic about what he teaches but even though its organized in a manner he understands. As a student its hard to understand what to study when it comes to the final. He has a hard time relating to students and in order to get an A in the class, one must take a written exam for the final.

Mark is the worst. He's so demeaning in class too. He questions why people don't know the answer to a question when he hasn't even explained it. Mark saved his rating by giving half of the class A's on the final. Also, go to the TA hours if you don't understand the homework. It really does help

Most difficult professor I've ever had. 202 was the hardest class I've ever taken, and 302 is not much easier despite what people say. Forget about an A unless you are a real whiz. I'm a straight-A student and I got a C in 202 and B in 302. I respect Haug's outlook on life and am grateful for some of what I learned, but I would never take him again

Haug is the WORST professor at KU. He is so smart but he doesn't know how to teach and makes you feel like an idiot for not knowing the answer. The labs are only 20 minutes long and are meant for 8 year olds, but the tests are IMPOSSIBLE. Multiple choice from A-K and things you have never seen. I studied for weeks for the final and got a 50%

I have already have Masters in Statistical methods from Tex A&M, but KU made me take this class to get my Masters in Business. He might as well be teaching in a different language. I've had lots of Stats already and this teaching method of his is full of trickery and belittling students.

Considering Haug teaches two REQUIRED stats classes for all business students, they a ridiculously hard classes. He's too smart to teach a lecture of over 400 different types of students. His class is set up to make you feel like an idiot. I felt just as miserable in this class as I did when I was in the engineering school.

Quiz 95% of the time, nearly impossible to get an A, didn't take away much useful knowledge from this class

He's the kind of guy I wouldn't mind being seated next to on a short flight and getting to know. Definitely not the type of person I want as a professor.

If you take this class, take HQL points seriously. Most people don't realize how important they are until it's too late to recover. Study for every quiz and never miss class. Do not take this class if it isn't required for you. Only a very slim percentage of students in this class get A's. Most students, even quite smart ones, only get out with C's

The class is pure insanity. Mark expects his students to think and then give the answer. If you are expecting A or a B in the class would recommend to attend every HQL you can and see the TA in their office hours and start working on the final review when he posts it online. The questions are sort of similar but less chances of getting right.

The average on the final was a 9/20 and when he went over the questions he kept saying he didn't understand why the scores came about to be like that. Honestly, I don't know if he understands that there's a correlation between his teaching and test scores. He may be a smart guy but that means nothing if he can't teach properly. He needs to change.

worst teacher in Ku

Most frustrating experience at KU. Haug constantly references how this course is designed to teach one to solve a problem, but unfortunately his needlessly convoluted lectures make it so your TAs are your best bet. Haug is a nice man and is clearly a very intelligent professor, but his teaching style doesn't adequately support the difficulty level.

Spends most of lecture on a philosophical adventure. He teaches a little statistics, but reserves a majority of class time convincing us that statistics is important in marketing and finance through random case studies. The daily quizzes are full of tricks, and you're chances of a decent grade equal a coin toss, from a statistical perspective.

Haug constantly interrupts explanations of core formulas with unnecessary details in case studies or philosophical anecdotes/poetry. If Haug wants students to learn to solve a problem, then he should actually teach them the material first, and use the case studies designed to truly test understanding after people understand the base process.

Haug did not teach the material well at all. Had to rely on TA to learn everything from. He is a teacher that likes to trick his students on tests and quizzes.

No textbook, rambling lectures that consist of 80% unrelated material and 20% content most days. Grading scale designed to be as hard as possible to pass (1000 points, 600 from quizzes/labs, 100 from midterm, 300 from final). No textbook. The only book assigned/used has nothing to do with statistics. Not enough time given for quizzes and tests

Haug is by far the WORST professor I have ever had. Stats should be taught as a math class, not an idiotic philosophical take on life. Does a poor job of teaching the material. Goes over the simplest form of equations in the notes and then practice problems have content that we haven't gone over in class. Terrible terrible terrible terrible man.

I'll give it to Mark; he is brilliant. However, the class is entirely arbitrary. The point system makes it very hard to pass with a decent grade. If you're looking to get a good grade in this class be prepared to struggle. Go into class with the mindset of surviving, because that is the best option you have to pass.

The worst professor at KU. This is simply a weed out class for the business school. Be careful about skipping you will not do well. There is a quiz basically every day but the class does get a little better after spring break. Mandatory seating chart and no laptops allowed in class is a bummer.

You must go to every class because it basically has at least one quiz. And you can't predict quiz's content. He likes to speak questions orally, so you have to listen carefully. I feel that Mark's thinking is very jumping, so sometimes I don't understand what he wants to express. Hard to get a high score.

Honestly I feel like I've learned nothing from this class. Boring lecture and tough exam

The worst formatted class I have ever taken in finishing my first undergrad degree or in the one currently working on. It is designed to make it as hard as possible to pass. Little is explained in class due to his rambling lecture style. Egotistical in the extreme and likes to belittle students whenever possible.

This class is a colossal waste of time. Little to no stats actually taught and most of the class periods are spent on philosophical adventures and whatever stories he makes up. No text book, little to no actual explanation of problems and how to do them and a really bad grading policy make this class much harder than it needs to be.

Has zero understanding of how to teach/help students build understanding of basic and complex topics. Most of his lectures are more or less stories with minimal amount of content. Examples done in class Are the simplest form possible which makes the more complex problems in the practice sheets more difficult. Not looking forward to 302 at all.

Lectures never made any sense in this class yet we had quizzes every single day, sometimes up to 3 quizzes in one class. Make sure to go to all the classes at the beginning of the semester to get all the HQL points, youll need them. Midterm is easy but final is impossible. You never actually learn math in this class and have no prep for the final.

Calls on students by full name daily and unjokingly belittles them in front of 400+ kids if they can't answer. Once told a student he should consider dropping the course around the third week of classes - a required course for the b-school, that only he teaches, that most of his students are nearly 2 years into obtaining. Demotivational to no end.

Hes a very intelligent person, but his teaching skills are just SO bad. He expects people to be an expert on 35 formulas he talks about for 2 minutes during lecture, he spends more time talking about stories that relate to the problem than actually doing the problem. Utilize your TAs, do the study set problems and STUDY, lots and lots of studying

Poor teaching strategy.

Mark Haug is a very poor communicator. This complicates many things about his statistics class. 1) He does not clarify key points in class, so be ready to learn everything you cover in class on your own 2) He'll tell long stories in class that aren't relevant to the topic 3) He will not give sufficient answers to questions asked in lecture 0/10

Mark Haug is one of those professors who just are too smart to teach. He moves too quickly and doesn't understand why we don't get his lecture. I relied ENTIRELY on TAs because they actually know what you're going through - Mark is just too unapproachable. It's like he already knew statistics coming out of the womb...

This was the worst class I've ever taken. Nothing I learned in class and lab or studied was on the final. He is a terrible professor and doesn't have to care because he makes bank.

I spent 18+ hours studying for his final from the review packet that he gave us just to show up to the final and have it been on everything except for what he gave us to study.

That's an unfair grading system. Everyone stands at the same starting line, 600 points and competes for the final exam. If you failed to get 300 points, we lost A!! Mark is the most terrible professor. You learned nothing from him. You definitely should break with people who recommend this guy to you!!

Mark is suck, he sets the final exam to 40% of the total grade, and the answer options are from a to i. Would it seem smart to you to do this? No, if you need to examine what you want, you should tell us in your daily homework, but you didn't do it! All my classes are A, DSCI202 I got B, irrational setting caused the final exam to count on luck!

Throughout my college career, Mark Haug is by far the most intelligent professor Ive ever had, but that intelligence does not translate to his teaching abilities whatsoever. He makes the final impossibly hard, out of the 60-some pages of practice problems, zero (or anything similar) were on the final exam. Getting all 600 HQL points is a MUST.

This class is awful. I absolutely can not stand him as a professor, he doesn't care about the students AT ALL. He doesn't teach anything and assumes you already know it. Too bad KU doesn't offer another professor to teach this class because everyone is stuck with him. The final is multiple choice and 20 questions where it equals 30% of your grade.

Does not lecture anything specifically on tests. Many people say he just makes you work for it, but attending every class and trying your best does not mean you should get a C. Having to teach yourself is not just "working for it" the professor should teach what he is testing,

He's the worst professor I ever had. Mark totally not understand how to teach students. Almost nobody can follow his lecture. You will find that even though you are listening very carefully, you never know how to do your quiz. However, in summer quiz has 100% of your grade. GG my friend. Now BCCC opened this course as STAT1845. Go barton!!! No Mark

he is trying to to really catch cheaters so he makes the whole class suffer with his material and his lectures are vague. they won't really be straight forward and he makes it hard to understand.

He is the worst professor ever and has the most difficult grading scale. He does not care about his students success and I truly believe he wants to see them fail.

This is one of the worst classes I have ever taken. Between unfair time limits, lengthy video lectures, and a final that determines your grade whether you like it or not, it is clear to see that this man does not know how to run a class.

To even be allowed to take the final, you must have an equivalent of a B or above. However, then to get an A you need 9/10 on the final, which is multiple choice with 8 answers per question, no partial credit. The score on the final is the grade you get overall. You can skip the final and get a C, or take it and possibly get a D or F overall.

This class is probably the worst class I have ever taken. It is very lecture heavy with long complicated lectures and the professors seem to not care about their students. Also, the final exam is pretty much your entire grade. I do not see the point in one test being your entire grade. Good luck if you take this class

The final exam decides your grade, and it isn't fair for people who have an A or B the whole class. The people who have a C stay a C if they do not take the final. But the people who have an A or B if they do not take the final end up with a C even though they worked hard all semester. The exam is difficult and determines your grade.

Prof. Haug's BSAN 202 is one of the worst courses that I have ever had the misfortune of taking. The grading system is ridiculous - I've never seen one like it in 14 years of schooling - and inherently creates barriers to student achievement. The blatant disinterest in the success of his students is shocking and unbecoming of a KU instructor.

Made it almost impossible to get an A in the class. Practically sets up students for failure. Bad professor, even worse grading setup. Would never take his class again.

Lengthy lectures were just Prof Haug reading numbers off a slide, no explanations. This class is nearly impossible for people with no prior statistics experience. Ridiculous grading, only matters what you get on the final (don't take it if you're not confident). Rely on your TA because that's the only teaching going on. Do the lab work before lab.

I never had a C in my life until I took this class, I had a perfect score on the HQLs so I thought the exam would be similar to the quizzes and labs from the class. I was wrong, the exam was way different from what I expected and ended having a C.

Worst class I have ever taken and by far the hardest. But it wasn't the stats that made it hard. We had 12 hrs only every Wed. to watch hours of lectures and take multiple quizzes. Haug is a smart guy, but so smart that he can't dumb it down for the rest of us. Just try to get as many points as possible and opt out of the final to keep the C.

Worst class I've ever taken. If KU cared about their students, they would fire this guy. Entire class is taught through excel, but the final worth 40% of your grade and is pen and paper.

Class is taught through excel and the final is 20 multiple choice. Went into the final with 100% and got a B in the class. Class setup is unfair. No matter how well you prepare for the final you still will struggle to get an A. Haug taught both of the only classes I've ever gotten Bs in. Man shouldn't be teaching and is disrespectful about COVID.

Where do I begin? He's entitled, rude, and unhelpful. He thinks that statistics is the end all be all of the world. His lectures don't teach anything because all he does is go through case studies. If you wan't to learn anything you have to find extra material to work on outside of class. Your best bet is doing that and utilizing your TA.

I consider myself mathematically inclined, I am pursuing a math minor alongside my degree. Mark is the worst 'math' teacher I have ever witnessed. Mark Haug is a pseudo mathematics teacher with nowhere near the education required to teach mathematics. Mark seems obsessed with appearing to be smart. Pathetic class from a business & math perspective.

I am not saying prof haug is a bad person, I think he has good intentions. However, he is simply way too smart to be teaching a lecture hall full of college students statistics. The way he explains things makes no sense. I tune out lecture every time because whenever I try to listen, all it sounds like is random numbers and jibberish.

It is truly a wonder that Professor Haug is still teaching at KU. He refuses to change his curriculum, and offers no help to students. The way the class is structured is terrible, and something needs to be done about it. This is a required class to enter the business school, yet only 40% of the students who take it pass.

The worst professor at the University of Kansas. All Mark cares about is finding different ways to screw you over. KU should fire him, I hope he ends up working at Checkers someday.

There is an equivalent class offered at JCCC, just take it there. Mark is terrible. Class structure is the worst I've seen in my almost 15 years of schooling. Final exam practically decides your grade. My advice: try as much as you can on the Freq. Exams and labs/ HWs, then just pray you pass after the final. Wish I could give him 0/5.

Mark Haug does not teach BSAN he gives you the equations with no explanation and then rambles about topics that do not even relate to the equations. Most of the time 2/3 of the class leaves right after his daily frequent exam. Save yourself and do not get Mark Haug

This class will bore you half to death but will end up being extremely difficult. If you miss lectures you will not pass the class, but lectures seemed irrelevant- many tangents. Lab is the only time I felt like I learned anything. Grade is completely determined by your final. Hardest class in the B school by far, you are set up to fail.

There are 20 pop quizzes and one lab quiz a week which are the ONLY grades (plus a final). This was the worst class I have ever taken at KU. The lectures made no sense but lab was extremely helpful. As for the final, good luck guessing. There are answer choices a-j

There's not enough space here to say everything that I want to say. It's a hard class. If you work hard you can do well. Mark is a psychopath. He makes everything hard on purpose, and his goal is for you to not get an A in this class. He's also too smart to teach.

One of the hardest and most ridiculous classes I've ever taken. The format sets you up to fail.

Worst professor I have ever had. Class is set up to make you fail and he loves it. Entire grade depends on final exam.

This guy goes on nonsensical tangents for an hour and 15 minutes and passes it off as a lecture. You wont learn anything of value to the business world, and its shocking that hes still allowed to teach (probably has tenure).

Dude is tuff

Absolutely horrible professor. Acts like his class is the only one that matters. Have an A in the class but my final grade depends all on the final, of which he does not give you a formula sheet, any study material, or let you opt out anymore. One of the worst classes taken

Do not take his class. Wait until they hire a different professor. He is terrible.

This guy went from a 2.7/5 to a 4/5 pretty much overnight. These last 9 comments are probably his TAs or he made 9 accounts. He is awful and this will probably be the worst class you ever take in your life. After every class everyone walks out saying how they hate this guy and how hard the class is.

Worst professor ever! Went to every lab, lecture, office hour and still ended with a D in the class (had an A- going into the final). Terrible and I'm glad he got fired.

I really have no clue what happened in this class. Before the final and the curve I thought I was going to get a D maybe a C and then I ended up with a B, so I am happy about that. However having said that it is very hard to gauge where your grade is at throughout the semester.

He treats the class like he's weeding people out of the business program more than teaching. He made my anxiety issues worse.

Honestly he just is not good. You could have a 99 the whole semester and at final you could fwi

Awful professor. Boring class. Reads off a power point the whole lecture. Rambles about irrelevant information. Nothing good to say about Professor Haug.

EQs will make or break your entire grade

Mark is not the best professor out there. It is very lecture heavy and it does require a lot of outside work to get a decent grade. While I know all classes have work outside his is to a different level. It is very hard course with him. He also just assumes you have all this background knowledge.

I'm a sophomore in 2022 and Haug's BSAN 202 has been the least helpful class ever; so many things wrong w how this class is taught but first and foremost is the final prep work they "give". There isn't any. They have practice problems but they don't provide formulas or answers to see if you did the problem correctly + still on blackboard... alright

This class is known as one of the worst classes in all of KU the teacher is absolutely terrible. The content is easy but he makes it impossible to learn from the boring and pointless lectures. Nothing he says actually makes sense and it is better to just learn it yourself. He doesn't care about his students and blames his students for doing bad.

This class is terrible and don't listen to anyone who says otherwise.People who graded him above a 2 are lying. I have an A in class which doesn't matter because your final grade is based on your final test grade. Which the final is almost impossible.This class is full of in class surprise test questions and bad lectures.He is a terrible teacher.

This teacher does his own ratings because there is no way that anyone likes this teacher. He is by far the worst teacher in the business school and he criticizes all his students for not knowing the content. Bad teaching, boring lectures,bad rambling. Grade = 100% of grade on final. Grade throughout the semester caps what you can get on final.

Whole grade depends on EQs and the final, which sucks.

You're grade doesn't matter until going into the final. I have an A right now, but am shooting for a C on the final. Since its almost impossible to get higher than that. However, If I came in with a C and got 100% on the final then my final grade would still be a C!!! Worst grading system ever. Not a bad guy, but a very bad professor.

This professor dedicates his life to trying to make his students fail. All the people I know wish they hadn't taken his class. Absolute garbage of a teacher and he should be kicked out of KU. I am impressed that with the quality of KU, they still have piece of shit professors.

Mark's goal is to watch students struggle, there is a reason that he is getting fired. He has a systematic approach to teaching and it only fits students whose brains are wired that way. No, the class is not as hard as people say, but you do have to do a lot of work outside of class which a lot of students do not like. The grading system is dumb

Terrible. You can do amazing on the final but it won't help your grade at all. Only make it worse

Final can only hurt you but bro gave the final answers 2 weeks before to save his job

I had an A in the class but the final dropped me to a C, even though I didn't do that bad on it. His grading is messed up a ruined my GPA. If you can avoid it, do not take his class! It's just as awful as everyone says it is - they are not exaggerating.

Worst professor ever! He really does play mind games with his students. You never really know what your final grade will be based on. The final exam will only hurt your grade. His goal is to tank students' GPAs in a 200-level class.

This is by far the worst professor at the University of Kansas and I am a sophomore in the Honors College that was Pre-Med. In his class, you have to get a specific letter grade which is purely based on your Exam Questions (20 pop quizzes) and Labs. Then based on that grade, that is the highest grade you can receive on the final or in the class.

Mark Haug lacks respect for his students. His exams are unnecessarily difficult with answers meant to confuse students rather than test their understanding of the content.

Do not take Bus150 from him. He doesn't teach anything during class, the other teachers do. Other teachers help go over the quiz questions before the quiz (like basically answers) and he does not. He also says he has never read the quizzes and tests so he doesn't have to “lie to us.” The class is designed to be lots of work but he makes it worse.

I am pretty sure I have never hated a professor more. While his class itself wasn't difficult, I don't think that I have ever felt more uncomfortable sitting in class than with him. If you are a minority in literally any way, DO NOT TAKE HIM. The way he covers the materials is very biased to his own beliefs, which can make it difficult to learn.
