Aggression vs. Altruism: Crash Course Psychology #40

[@JaeEnceeti]

Just finished watching all 40 episodes and wanted to give a quick shout out to the graphics team Thought Cafe, the animations and graphics are awesome and I love all the references!

[@quinnross88]

I love how on 4:46 he casually threw in "Okay? Okay." from the fault in our stars reminding me of that painful, painful book made by his brother

+Musicyay12 psych is fun interesting but not for the faint hearted. We do it for the love of it, if you don't love the field don't do it

[@Rabbitthat]

+Musicyay12 it depends on the course you do, the university, and the country you do it in, my university gives books to first years that americans study as postgrads.. I am not bragging.. it is TERRIBLE. They use terms that they expect you to know because they were written for postgrads, terms so obscure you can't even find them on google we then get exams that test you on remembering the most minute detail rather than understanding of overall ideas

[@Rabbitthat]

so far I've been scraping a pass. Except with social psychology, aced that :D.. Thanks for your well-wishes! Musicyay12

[@kelseyrankin73]

Bummer that the Psychology course is coming to an end. I would love to see a series on educational psychology-- many viewers of Crash Course are teachers or college students on their way to becoming teachers. Please consider it! Love you guys!

And one cram of all 40 weeks squeezed into the two days before the AP Psychology exam finally comes to a close. Thanks to Hank, I am feeling pretty good about a five. Thank you for this awesome program you put on, whether or not I am a bit late

[@cobalteagle328]

Gravity Wave Did you get that 5?

[@ToxisLT]

done, all 40 in one lazy sunday - can I print my degree now?:)

[@MasterPoppers]

+Toxis This series is merely the tip of the complicated iceberg of psychology, much like the conscious.

[@ToxisLT]

MasterPoppers still not a science though, not yet.

[@Rabbitthat]

+Toxis i want a 6 and a half hour degree too!

[@tyleroconnor3035]

+Toxis Do you know what science is? Pop culture tends to slap the word 'psychology' on any cute little idea involving the mind, but psychology is a true and effective science. Psychologists use the scientific method and control experiments just like any science does. Complex variables can skew results, but that is true of any complex science. The mind can't be viewed directly, but neither can many particles -- physics is never questioned in its validity.

[@ToxisLT]

Tyler O'Connor yes, except that is not what happens, at least according to the people who recently tried to replicate 100 published psychology experiments and found that more than half of them failed. And not according to Paul Bloom, the Yale psychologist, who said (on Sam Harris podcast) that psychology right now is basically at the same place astronomy was before Copernicus. So yes, I wish psychology was science, and it is going to be someday, but right now, I always said, psychology is our last alchemy. And there was nothing wrong with alchemy, but it was not a science until it became Chemistry.

[@leahfrazier4910]

Dear PBS you literally are the best online study tool Ive come thus far online. You make learning for me exciting and fun, sounds cheesy but its that simple. I'm an ART major so the animation you use is very stimulating in your lectures. A+ I love this guy.

[@Thiefree]

The bystander effect has always really concerned me. I mean, I would have said something, but nobody else seemed that worried, so...

[@MrCoolguy106]

That's what I was thinking. I probably wouldn't have said something not because its all part of my malicious plan to be the only survivor of a fire and let the other 2 people fend for themselves, but because they didn't seem that worried, so maybe its a regular thing, or part of the test that i somehow missed.

[@TheAureliac]

I think we're worried that we'll look foolish.

[@youcefsb4708]

THANK YOU Hank and all Crash Course Team, that's the least thing someone can offer you back, Thank you so much (after finishing History, Philosophy, Economics, Sociology and Psychology)..

[@andresymedio625]

I have come to love these videos in a way I can't even explain. Every night I'd get to the PC, check the youtube page and see if there was a new video on the psychology course. These videos have somehow become a big part of me, they have been very useful for my college studies, but not just htat, they have helped me to understand people better, and of course to understand myself too. I'd like to deeply thank you for doing this, Can't believe it's been almost a year of Crash Course psychology!

[@mattiasfagius5116]

I just wanted to say thank you to Hank and Crash Course for the psychhology-series! I have seen the 40 episodes and gained lots of insights about both myself and others, as well as opened myself to the world of psychology. Most likely I´ll watch many of these episodes again to understand things better, and maybe read more in chosen subjects to deepen my knowledge and understanding. To publish such great content for free like you do on the internet is a truely awesome thing, keep it up Hank and John and all the others working for this project! Greetings from Sweden!

[@orca8439]

iIwish they would have kept going tho.:(

[@Steelerbacks]

Thank you for all the psychology help! I watched all 40 videos and I found them to be good refreshers of old information as well as great sources to new info. With the AP exam tomorrow, this was exactly what I needed, and now I feel prepared to get a 5!

[@cassiedunford6101]

Hank you have to continue this series!! I’ve been using it since it began for my university exams! Today’s exam is Social Psychology and Just watching a couple of relevant videos before the exam really jogs the memory of the revision I’ve already done!

[@alannar.8701]

Thanks for basically giving me all the sources I needed to prove that Lord of the Flies is an inaccurate model of society for my research paper. You guys are the best.

[@alannar.8701]

Oh hey you said Lord of the Flies how did you know

[@RavemastaJ]

Except that it was totally how things were going until an outside force stepped in to change it. Without co-operative goals being created and dropped onto a group from on high, there is no reason to stop the aggression. Competing for limited resources (time on the basketball court, baseball diamond, seats in the cafeteria) will always lead to conflict, until you completely destroy barriers and assimilate both groups into one group. This is very easily done in children...but not so easily in adults. In fact, this is generally only done after the complete destruction of a culture (see the Native Americans for an example).

[@alannar.8701]

ravemastaj Co-operative goals like... building shelters? Getting food? Getting off the island?

[@RavemastaJ]

Alanna R. None of those are co-operative goals. When you go to the bathroom, do you go with 10 other people? If you built one, would it be a communal latrine? No, you probably think of a single toilet in a small room with running water. Building a shelter is either for you, or the friends that helped you build it. At that point, they are in your "in-group," and everyone outside of it is in your "out-group." That's why Lord of the Flies became increasingly violent as the story went on - one side tried to use socialism and group goals to help the little children who couldn't do anything (think of the conch shell), while the older kids broke off and did their own thing, like killing pigs for food and fun (think of the little "in-joke" they created after the hunt). The "co-operative goals" you have described only work in the context of a single group. As soon as there are two competing groups, the dynamics fall apart into chaos. Like I stated in my first comment, you have to destroy barriers and make both groups assimilate before they can be considered ONE group, which is generally a messy process.

[@alannar.8701]

ravemastaj No? Either you don't understand LotF or you don't understand the experiment. This experiment even had an in-group and out-group to start with, whereas LotF didn't (they eventually formed, but weren't there from the start). The shelters can be compared to, say, the water tank (idk if Hank talked about it in the video, I read up on the experiment after I saw this). It's a thing that everyone needs, and that is more easily accomplished in large numbers. Your argument could be just as well be used for the water tank, and the experiment disproves its validity. And yeah, no. They didn't destroy barriers first. To use the water tank example again, it was like, "Hey, this water tank is broken. Fix it." They did nothing to make both groups assimilate. Besides, there was only one group by the time they were, say, building shelters.

[@level5productions]

I have loved these. I am taking psychology at A level here in the UK with the hopes of getting involved in counselling psychology as I have experience with mental illness (I have OCD) and I want to help people who struggled like I have with mental health. These are so fascinating and I love them, I also get a nice feeling when you mention something that I recently learned in a lesson about which is funny :D

[@vinhvu95]

Keep learning, there's no point stopping

[@level5productions]

Oh I intend to ;D I love psychology and find it so interesting as well as just having a yearning desire to help others

[@ThatGuyYouArent2]

level5productions Just try not to alanyse yourself too much, especially not your present self. That can lead to a LOT of distress.

[@Kronecraft]

I'm ADHD.

[@christine1902]

Shawn Kroner I have bipolar disorder, and I loved the episode about bipolar and depressive disorders. I didn't learn a thing with that video due to good psychoeducation but I shared it with friends who didn't understand the disease very well. I loved the rest of this crash course and I'm kinda sad it's over now.

[@heavyweaponsgaming]

This can't be the end! How can it be a psychology crash course series without even mentioning ADHD? It's one of the most complex, common, and misconceived psychological phenomena out there.

[@permutationsofdumbideas6967]

heavyweaponsgaming I know right!

[@gperson1967]

Oh come on, special snowflakes much? I have ADHD and, with the right amount of doctor mandated meth substitute I do fine. 👍🏻and have for 30 years.

[@lovelyfrenzy1]

heavyweaponsgam I get​ agreed. To this day I am still bothered by it, to the point were I lost a bit of respect for them.

[@MMurine]

While the topic certainly deserves discussion, I don't believe ADHD warrants the same attention that most of the other disorders presented previously did. In my experience, the condition is only functional. What I mean is that it impedes my ability to pragmatically function, but doesn't directly cause any form of emotional struggle. It makes life hard, not painful. Admittedly, my experience with ADHD is likely limited in comparison to yours, seeing as I'm only 14, but I believe it best to state my thoughts on the matter.

[@nicklewis470]

heavyweaponsgaming you forgot misdiagnosed as well

[@小島淳之介]

Thank you very much for all 40 episodes! I really appreciate the animations, graphics, and, of course, Hank's explanations. They have definitely sparked my interest in the field of psychology. Good luck to all learners!!

Thank you so much for this series. I absolutely love the way you present the material. Although I love my Psych 101 prof, I think you do an even better job of really getting my mind to wrap around these concepts. Keep up the good work on this channel. :)

[@jochembroodhuys7273]

It's only fair to say that I really enjoyed this psychology crash course. It's absolutely amazing how you managed to put in a motivational phase and a table of contents (besides the actual curriculum) in only ten minutes. The motivational phase really gets us hooked, the lovely visual support also helps to keep the attention. The table of contents or the summary as you will is really helpfull to check whether you really understand or if you need to watch it one more time. I will definitely start donating when I'm financial stable. But for now let's start an other course.

[@pachabee]

Wrote summaries for each video in this series, for extra credit in my community college class. Was enjoyable, though took a whole semester, haha. Thank you.

[@nadiact-ie5hy]

+Calvin Zero Who knows, it could increase all humans altruism. and we may start teaching out kids to do the same and life gets better i believe an alien invasion would be catastrophic, yet a lesson to pass down.

[@MgaMan-mr9pw]

Pokemon Trainer I say that we just start over in a place that doesn't have children on it yet, like another planet or a small isolated group of people, and experiment on them. Inform them that they have to tell a tale of alien catastrophe and see where it goes from there. The people would of course have to volunteer. There's no sense dragging people out of their homes to lie to their future children in isolation.

Thank you for keeping the fire alarm sound effect low. Unintentional altruism! My dog has a very adverse reaction to that sound so we both appreciate it!

[@leigha.b.1875]

I don't think the experiment with the 1 or 3 people in a room thing. I think a big fact in the one with the oblivious actors would be that the actors are oblivious. The person probably would think "maybe I'm just seeing things" or "maybe these two know something I don't. They don't react so maybe I shouldn't either" which could account for the low percentage.

[@skellymom]

Or, peer pressure. Humans of all ages succumb to it. And, you don't even have to know the people around you very well.

[@peterDcontact]

he didn't say they were unreasonable for doing that, but the fact is that if there is a smoke in a room that doesn't suppose to have smoke, there is a high percentage that there is danger and you aren't loosing anything if you mention it to people around you

[@Twosocks42]

Actually, you nailed it. :) In those experiments, what they found is people looked to others for cues, and were overestimating how good at reading themselves the others were. So, if "Bob" were in the room with "Jill" and "Todd", Bob would look over to Jill and Todd to see if they noticed anything. If neither of them seemed really aware of it, he would assume he might be wrong and go about his business. In the case with other real people. *sometimes* they caught on, but a lot of times they did not. However, with actors who are feigning complete ignorance, a person was much more likely to assume that they really were just imagining it, because the other two people seemed completely oblivious to it.

[@erraticonteuse]

Twosocks42 And this is why we need autistics and aspies and other congenitally socially awkward people, to freak out about the fires everyone else is pretending not to see, because it doesn't occur to them to also pretend not to see it.

[@leigha.b.1875]

lexidizzle but testing on people who dont have that reaction wouldnt tell us the actions of people who DO pretend not to see these these things, I only made the orginal comment because i wasnt sure if that was a factor in the experiment or not.

[@philconnors5692]

[@PSspecialist]

I don't believe anything we do is ever selfless. I believe there's always self-interest involved. I don't care what you do. You can give your entire life's savings to charity, you can donate your kidney to someone you don't know or whatever. You're doing it for recognition or for that feeling of "I did something awesome today, I should feel proud" or even because you believe in heaven. (ESPECIALLY if you believe in heaven, you're never really altruistic. If you believe in eternal life after death of course you're gonna be nice, especially considering the alternative to heaven.)

[@aquakairi10]

While it is rare to find true selflessness, I have seen it. I've seen plenty of people do selfless acts for absolutely nothing. I've done it a few times myself.

[@BrianBors]

ScarlettHorror But you got a good feeling from it right?

[@Timasaurus007]

I agree with you, we can lie to ourselves, but truthfully, we're just commiting self-interest, but is that so bad? I mean we get a good feeling out of it and the individual we help is better off, so is it an issue that it is all for personal gain?

[@error2k2]

I don't know about you but I've found wallets with loads of money, lost iphones and smartphones plenty of times. Even though I could have taken them, I decided to return them to their rightful owner every time(one time my colleague was like "keep it!"). One time, my gf had $300 in her purse and she forgot it in a Target store, someone found it, counted the money and left it with customer service making note how much was there so the employees wouldn't take the money. Unfortunately, the amount of aggressive and selfish acts I've witness outnumber the kind and selfless acts. But I hope when someone sees a kind act they will be inspired to do the same. *edit* oh and I'm an atheist and I don't believe in life after death (heaven or hell).

[@skellymom]

So you only doing something good rests with avoiding eternal torment in hell from an angry god? In your point of view its the fear and blackmail that really makes a person "altruistic". I don't believe in hell or gods judgement. Sometimes I do good things because I can empathize with a person whose predicament is dire. It bothers the crap out of me to see people struggle horribly, so I intervene. While I may not personally know that individual, I understand what its like to suffer. I think that's called empathy.

In my psychology class we were given a gruesome example of the Bystander effect. A woman was raped and stabbed in the middle of a street late at night. The people in the buildings nearby had heard her but no one called the cops. The attacker came back and raped her again and then escaped. The woman ended up dying. When the police finally got there and asked why no one had called the cops, the summarized response was "We thought someone else would do it".

[@catief1031]

Probably. It's been a good number of years since I heard about the case so I can't quite remember the woman's name.

I'm sad to see the end of this course because as a psychology student who learns best with visual aid and examples this course was really helpful although it only touched on the basics

Crash course psychology season 2 please!

[@MegaFenix1234]

+Pata Fea That would be helpful when I take psychology next school year. I wish he made videos on sociology.

[@Rabbitthat]

There are entire sociology courses available online. Crash course is only a few hours long and just gives you a brief overview. But yes, crash course sociology would be cool. If you want something as exciting as crash course (rather than dry video tapes of college lectures) try the School of Life, they have a lot of sociology videos.

[@MegaFenix1234]

Yea I agree, and thanks for the recommendation

[@Rabbitthat]

There's also an online social psychology course by Rob Willer, spread between psychological social psychology and sociological social psychology, it's really fantastic. Of course there are hundreds of courses online, but I recommend this one because it's funny and therefore doesn't require the levels of willpower that others do.

[@MegaFenix1234]

Thank you so much for the recommendation and I appreciate the time and effort you took for this. I watched one of his video and it was relevant to one of the topics in my sociology textbook, and I enjoyed it.

With all the things happening in Ferguson, this episode has been enlightening. Thank you.

I have done many things for others, so much I ruined my own life protecting others. Being honest and trying to be good is hard because there is a price in the society we live in. Very few will be there to catch you when you fall for doing good but they are always around to reap a reward from you or because of you. At first I did this being a traditional Native American, then, I do it because wether there is a God or not, I refuse to be just like the social norm in America of rugged individualism, self centeredness, materialism, and thinking GOD gave you riches while the same God turns a blind eye to murder and People starving.Sometimes I wish I could be one of those mean folks I described above but it is just not in me to be that way. Sure, I can get quite mad at selfish folks who try and do that to me and others but as far as ruining their life or beating them no.

[@gperson1967]

Good for you! A life well lived is its own reward if, at the end of the day, you can look back on all you have done and felt deeply that you have done well. And that may be your only reward.

[@WardhaMuneeb]

Amazing content! Finished watching all 40 episodes! Thank you again.

[@julianm.9980]

I want to tell my parents i think I have mild anxiety but I'm too scared that they are going to say you are making excuses for yourself what should I do?

[@julianm.9980]

I also think I have mild add because I have many symptoms of this as well

[@koopatroopalove]

I don't know your parents of course, but as adults, I'm sure they'll understand. Everyone has experienced anxiety in their life. If you don't feel comfortable telling your parents yet, you can talk to a friend or a trusted adult, like your school councilor (assuming that you go to school). It helps a lot talking to someone and getting all your problems off your chest. Good luck with your anxiety! :)

[@julianm.9980]

+koopatroopalove thank you so much I appreciate it a lot!

[@leahscrivs]

Julian Markevicius quite honestly, I think you should show them some research and possibly show the, some crash course videos. Maybe show them what a psychologist would classify as mild anxiety. Good luck! I myself have mild to severe anxiety but I take medication. Hope your parents can understand! Took me a year and a half to educate my parents on it. Even if they don't comply immediately, continue doing whatever you need to, to educate them on anxiety and let them know it's not to get attention or to make yourself interesting. Hope that helped!

[@beepboopblorp]

I can't believe this series is over! It has definitely been my favorite out of the crash course series :(

[@WrathOfMega]

8:23 Please never say 'Boo' in that context again. It's stupid enough when my peers do it.

[@MrFloobis]

At least he didn't say bae

[@DelaneyMB]

***** Regarding how you hate how people over simplify, I really don't think it's intentional most of the time. The truth resists simplicity. If people wanted to be as correct add they could all the time, they would either have to have an asterisk after everything or say so much that the original point could easily be lost. Simplification is just much quicker and easier. Whether it's better is debatable.

[@IceMetalPunk]

Boo comes from beau, which is the French word for boyfriend. So it's not really "stupid", it's just linguistic evolution.

[@WrathOfMega]

IceMetalPunk I don't dislike it because it 'isn't a word', I dislike it because it sounds like a desperate attempt to sound cute (combined with my pre-existing disrespect for most of my peers' maturity levels, which only compound how childish it sounds).

[@IceMetalPunk]

WrathOfMega What makes a French-derived word sound overly cute or immature to you? O_O
