People are so lucky to have had irl lectures with Dr Sapolsky. All of us virtual learners are as equally lucky! Thanks Stanford for putting these up online.
I love how the professor has these really humble moments where he made a little mistake or something, then goes back to being someone who knows more about psychology than I can even imagine.
This isn’t psychology tho
@@psychedandelevated2854 why not? There is not any pencil line between chemicals and resulting mental states and behaviour. He is teaching boichem/genetics and pyschology/sociology at the same time. As they are in our lives.
the only mistake I recall him making was calling men and women 'the 2 species', Freudian slip, funny and telling.
All whites are racist!!!!
It seems like psychology is really important to you guys.
I could listen to him read cereal boxes and be fascinated.
😂😂😂😂🤣🤣🤣🤣🤣🤣😂😂😂😂😂🤣🤣🤣😂😂😂😂😂😂😂😂
Whoaaa
For real
Sure thing.
im sure you love watching paint dry as volunteer work... i unno why it @'d who it did
If I were to attend Stanford, I would take EVERY course instructed by Dr. Sapolsky. He creates such an interest in what he is about to say, where you gladly join him in his journey through his lecture.
And he has such an amazing way of breaking down his topics in very palatable terms that translate perfectly in layman terms- which shows he has true mastery of the knowledge he possesses.
@Maria Callous this is his bio 150 class. This is an introductory course that is supposed to be a medley of scientific courses, so that students can get an idea of what the upper level curriculum will look like.
I love how Dr Sapolsky teaches everything with nuance. For any topic, he suggests x leads to y except with z. A good way to keep his students from seeing the world in black and white and instead a colorfully complex system
A few nights ago, I fell asleep with one of his lectures playing. I entered a dream in which I heard his voice as it played over the RUclips video, and I saw myself physically in his class and I was understanding things.
Lmao!!!

Stanford may I please have free tuition? I think I can contribute to our species’s advance in knowledge. Let me know when I can’t start. Please and thanks.

thank you for posting this course
also would like to have free tuition as I see there is a demand for it, so I am next in this line
Can you please add his depression and biology of religiosity lectures to the playlist? People are missing out on those wonderful lectures.
I had a certain understanding of evolution that I carried along for a long time and I used to always argue with and the picture was of a uniform linear model. advantageous traits simply would keep evolving rapidly through the selection of more magnified and amplified version of genes replacing the weaker ones. but the realm of social evolutionary biology is much much more complex than that. I wish I can have the honor of thanking doctor sapolsky personally as this course was one of most enjoyable experiences I had on youtube, and it truly changed the way that I view the world. Thank you doctor sapolsky. Abdulkader from syria
I am enjoying this excellent course too. Corey from Canada.
Oh my, completely relatable! I can't even sleep right because i always think of his lectures. This course completely changed the way i am. I swear to god, when i graduate senior high(I'm a HUMMS student BTdubs), I'm going to take Biology.
this video is so fucking out of date its not funny..
have a look at the most recent mummy DNA findings and yr about to realise its even less like you thought it was..
its looking more and more apparent now that the various prehistoric hominid species were in fact NOT various stages of evolution, but in fact separate, co-existing and interbreeding species, and that the various levels of interbreeding between these species are what resulted in the marked differences between the races.
so instead of being a linear progression, its looking more and more like a shuffled deck.. less like a game of monopoly, and more like a game of snakes and ladders
Sapolski
thank you grayham for demonstrating your stupidity by assuming a correction needed to be made where everyone else already knew what was meant.
What a delivery. No nonsense and well paced but with sprinkled with occasional humour. Commands attention so well that it's difficult even to pause it momentarily. Brilliant.
Response to 51:26 There was a young lady from Asia
With adrenal-based strong hyperplasia.
They soon realized
She was androgenized,
Which her mom thought was only a phase. Yeah.
Darn I'm proud of this, and no one may ever read it.
I read it and loved it! You should be proud
@51:17 .... challenge accepted.
There once was a hirsute young geisha,
Whose beard was renowned across Asia,
She replied to the query
As to why she was hairy:
Congenital adrenal hyperplasia.

You live a miserable existence.
@@ao9297 that escalated quickly
I shaved 2 minutes ago , my head as well 🤔
He probably thought about it for a sec lololol
Robert Sapolsky is great! :) I'd love to sit in for one of his lectures. It'd be like a rock concert for smart people. xD
so it would be exactly like a rock concert
very well put
Hahah I love this comment
i am addicted to science and this professor like my best friend, these type of people i love to hangout around and learn , for me he is the best Doctor and i kinda teach and explain for people the same way he uses
This series of lectures is just breathtaking. The clear structure, the recent information, so easy to follow, that I'm unable to stop watching.
57:00 onwards is hilarious. "Made the people jump off buildings".... "Half the people quit and went to business school" - nice to see that other fields also aren't considering economics as real science xD

Kind of a leap you took there, huh?
This lecture is mindbending, the amount of things we're told our whole lives about sexuality that's utter bullshit is staggering
Big up for Stanford to help us be less stupid and hour an a half at a time
hear hear 🍻
most things we hear are bs.
This is so good! He presents the research literature on humans and animal sexual behavior in such an instructive, yet fun and funny way.
Soo mind blowing, and the way he connects the aspects with his amplified view shows his dedication, an amazing experience to hear all these magnificent studies. I have so much appreciation for his job, gives clarity in such complex realms as it is behavior in the many forms it comes, and has to be explained in a neurological way to be trully understood. Must thank Standford for giving such magnific material to the RUclips community. Greets from Colombia.
Yes, I googled it. (on the farm), Mrs. Coolidge was taken to a large enclosure with a henhouse, filled to capacity with hens and little chicks, but she could see only one rooster. When she remarked about it, the farmer boasted of his “prize” rooster - one able to “service” the entire lot. She queried, “Just how many times a day does this prize rooster ‘copulate’?” When told that rooster could mate perhaps 35-40 times a day, Mrs. Coolidge twinkled to her host, “You must be sure to tell that to President Coolidge when he passes this way.”
Sure enough a half hour later, the President and his escorts passed that same henhouse, and was given Mrs. Coolidge’s “message.” Coolidge nodded, and was his usual silent self, until they were about to leave the area.
“Hmmmm. Thirty or forty times a day,” he twanged. “Same hen?” “Oh no,” said the farmer, “he services them all.” Coolidge didn’t miss a beat. “You be sure to tell that to Mrs. Coolidge,” he added. (From Presidential History Blog)
Patricia Heil hah, the professor was off here, that was a very witty reply by Coolidge
Patricia Heil so many of these kind of stories turn out to be apocryphal. But, whether it actually happened or not, it is awesome.
Human evolution
Please don't become a stand up comedian. That joke could have been told in three short sentences.
@@SnapCracklePapa I wonder why you felt the need to criticize when it was not necessary.
I watch these lectures as background noise to my projects, and still get caught up in his engaging presentation and interesting materials on umpteenth watch.
Coming from someone that spent more than 10 years at various secondary and university educational institutions (studying completely different fields) . . .
This guy is a brilliant lecturer.
I Can relate, this guy trumps most of the teaching staff i have came across in my university experience (which has also pushed the 10 year mark of uni xD)
1:22:59 Sadly he got this fact wrong; chastitybelts weren't actually used, as they were unhygienic.
They were satirically depicted; like joking that the husband would have a key and the secret lover would have the spare key.
I'm so grateful to whoever makes these available. Im uber grateful to Prof. Sapolsky. Thanks very much!
"You and me baby ain't nothin' but mammals
So let's do it like they do it on Discovery channel"
he doesn't include social evolution etc though so it's a pretty one sided view at human behaviour
I really must say I love this mans lecture. It is well delivered and well rounded.
These lectures would make an incredible docu-series
This guy is so interesting. One video started to autoplay and now I'm on my 5th vid.
Dr. Sapolsky is an absolutely perfect looking college professor!!...Oh, and he is an excellent lecturer as well :)
god damn hippy

As someone who is far more interested in mathematics and physics I'm surprised how interesting I'm finding this.
I majored in analytical Chem. a hundred years ago. Obviously, narrow and boring in hindsight. However, In my defense, I did almost flunk out from chasing skirts and associated activities. Neurochem./ bio. is fascinating but this series shows yet again...it is a Godsend to have virtually any subject presented by a passionate, knowledgeable, high energy and funny teacher. with no agenda....
Mind blowing stories i heard here.. Thank you Dr Sapolsky
Listening to him makes me so happy...
Would you let him inseminate you?

I want to see this guy and Irving Finkel duke it out in some kind of awesome fiery debate with a tantalizing visual of dueling beards. Is there any kind of venn diagram overlap between babylonian history and behavioral biology?
hey!! film the charts on the board! dont always need a close up on him!! but... either way.. thanks!! appreciate the vids!!
Love these videos. I listen while doing puzzles. I'm always vaguely thinking about whether it's the same person coughing in every one of his videos haha.
Me too. Im worried for them lol
😂This was 12 years ago im sure they're doing alright now.
The coolest professor ever
We need more of this sort of analysis sementically and chemicaly.
The cameraman is a legend at panning
The Coolidge effect is a biological phenomenon seen in animals, whereby males exhibit renewed sexual interest whenever a new female is introduced to have sex with, even after cessation of sex with prior but still available sexual partners. To a lesser extent, the effect is also seen among females with regard to their mates.
Or, in modern parlence, the "new and strange" syndrome that every guy will admit to.
@@geoffreybermingham454 what’s that

Sexuality in general was not repressed and it was embraced and nurtured. Through their myths, relegion, festivals, art, literature and sports.

Nothing I love more then free knowledge.

Best lecturer Ever!
does anybody know if I can find the handouts for this lecture?
lowkey "wallow in the world of pheromones" is one of the most fire lines of 2010 (and i am including all rap published in the same year) x
Which literature does he suggest? Is there any with this nice depiction which ends in behavior he wrote on the board? Thanks in advance
Look up the books Robert Sapolsky published. In addition to the content in his books, there are meticulous references to sources, like 50% of the book is references. Enjoy!
this one was confusing and there was lot of stuff to take in, have to rewatch
Anybody found those classics by Dr.Anonymous?
The correlation between sexual behaviour, aggression and testosterone in males is wildly fascinating to me from a sociological perspective
Hope the student tape his lectures, lotsa info to learn and digest!
Fun thing to know is that Wellesley effect or, correctly, McClintock effect, has been proven to not exist, so pheromones (or anything else) does not synchronize women menstrual cycles, it is just a coincedence that sometimes they converge. The corresponding systematic review was conducted in 2013, 3 years after this lecture, so Prof. Sapolsky or anyone else in 2010 did not know this.
the emotional roller-coaster i got with this one 😰
So helpful to learn about the world’s biology / thanks so much
Dr. Sapolsky is the consummate professor.
2011 I was just entry to university and no have computer and less my english was not enough... OMG I have been in darkness. Congratulations and thank you to share this excellent material.
Me encantaria enseñarte. Soy maestro hace doce años y siempre busco a estudiantes quien intetesan las mismas cosas que me...la majoria de mis estudiantes son psicologos, neurologo, psiciatres o estudiantes de psicologia. Pero obviamente, no podemos usar español, porque no hablo tan bien, asi que tienes que ser...de menos nivel a2.
Coolidge Effect 18:00... an old joke about Calvin Coolidge when he was President ... The President and Mrs. Coolidge were being shown [separately] around an experimental government farm. When [Mrs. Coolidge] came to the chicken yard she noticed that a rooster was mating very frequently. She asked the attendant how often that happened and was told, "Dozens of times each day." Mrs. Coolidge said, "Tell that to the President when he comes by." Upon being told, the President asked, "Same hen every time?" The reply was, "Oh, no, Mr. President, a different hen every time." President: "Tell that to Mrs. Coolidge."
Hey guys, which Sapolsky book should I read first? I love these lectures!!! Thanks!
Zebras book was very good, but i think that A primate's memoir is a more personal one.
Thank you!
@Stanford do not ever remove these lectures.
"All bonobo chimps play the guiter & sing soulfully" 😂 Sapolsky you're a hell of a comedian! 😂
What is exclude to you tube in the last two lectures?
Clearly explains sexuality. Even throws in humor.
Hmm…Stress and fear reduces sexual behavior and activity. This is interesting in the first few years of the ‘20s.
this is a good discussion.
The perfume study makes me so curious because there are so many types of perfume. How many in this current day actually have those “male hormones”?
Olfactory senses in rodents are highly evolved in comparison to humans.
In that the neurological pathways to said region to amygdala illicit massively different nature's. Albeit similarities do give a slightest inclination on the senses and processes involved in humans .
Great lectures 👌
The shade toward Jeffrey Miller was just fantastic.
I keep waiting for him to say, "And the answer is.... a Daily Double!"
37:58 All fascinating, but... did he just define "perinatal, before birth; prenatal, after birth; postnatal, very early development"?? If I'm not mistaken, I thought "prenatal" is before birth, "perinatal" is around time of birth, and "postnatal" is after birth. Can someone please chime in?
Can someone tell me what the readings are?
My question is; because we model our primal existence, and can continue our specific primal actions, what SHOULD we do for an optimal human future existence? If a goal of future human existence is to continue and expand the enabling of violence and chaos, I suppose our present course should continue.

I had a first long term relationship with a beautiful young woman who was born with adrenal hyperplasia and hypothyroidism. She was very open about her condition - perhaps too much for the ignorant early 1980’s and this then-ignorant mate - and had multiple predictable side effects. Beside the misfortunes of her familial “upbringing,” my stupidity about how to have a successful human relationship, her life was not all that it could or should have been…
I wish in retrospect that I had accessed additional information on her endocrine conditions and their attendant overt symptoms.
She was a good person.
people may think i’m listening to taylor swift...but i’m actually listening to Stanford 16. Human Sexual Behaviour II
A whole bunch of ovulation research he quotes has failed to replicate, unfortunately, which makes it hard to sort through which parts of what he's saying is true and which part isn't.

I wonder if "conscious" could simply be the constant to and fro of the PFC and the Limbic System
and perhaps our ability to successfully think abstractly is inextricably linked to PFC using emotional reactions (limbic system) as a means to assess thoughts.. and our true "cleverness" is caught up in intelligent/complex emotional responses, rather than in the PFC itself.. ie. intuition
aaah never woul've guessed that, thank you!
Thank you Sir.
I’d love to read the IRB the lap dance researcher submitted 😂😂😂. I’m pretty sure they didn’t have IRBs then but it would have been great, no doubt.
@JAYDUBYAH29 If you look in the suggestions now it is up . I think they just uploaded it in the wrong order.
Best flow in the game
And what of a female who flies solo??? What internal balance or imbalance occur???? And would that make it then difficult to engage into groups or rather make them more promiscuous???????
the transcript is hilarious - clearly this was not remotely edited!
Does anyone know where I can find that paper by doctor anonymous and beard growth?
yo, what is up with that chart at 1:21:21 ???
Thank you very much.
23:00 For the second rise in female sexual receptivity, does this take into account if a female does not keep count of when her period is about to come/when she last had her period? (without the mindset of "my period is about to come now I can have sex more safely")

Do you keep track of how many heartbeats you have? Not consciously, but your brain does.
Somebody know which book he mentions at 16:15 -ish?
Why Zebras Don't Get Ulcers
I've always been wondering: whats that word he uses quite frequently, it sounds to me like "dicotomous"?
greetings from abroad
dichotomous. from Greek dicho- and -tomy A division of something into two things/groups/classes.
if you like these videos you might also like contrapoints I think the way they give information is similar. Topics have some common themes but much more political
how more lectures is there
its really interesting to me that hormones and gonads affect tactile reception.
Testosterone - what casual relationship with dopamine in the male and oxytocin in the women creates a "bonding" for the male and drives sexually addictive behaviour?
This is interesting to say the least...somewhat detailed for the hour in which I listen (3.31am) however, mental note to self to pay closer attention to the knowledge he is so generously sharing with all of us on this platform.
Now that's awesome!
If I were a Stanford student paying big bucks to attend these lectures, I'd be very annoyed of their widespread availability, lol. Suffer!! This guys information deserves big audiences, thank you to whomever responsible for sharing, much gratitude.
When I was 33, my endocrinologist prescribed this Testosterone gel, even though I was already at a slightly elevated level.
I can confirm not only did I feel far better, the level of sexual behavior is definitely causal!
I think he's not quite right on Bonobos. They are less violent than chimps toward other Bonobos, but they can be rather harsh against intruders. Also, the sex isn't totally free. Male to male sex is usually very momentary and rarely leads to sexual satisfaction. Usually, one female is the most desirable, and the males face a hierarchical pecking order of how desirable they are to females, who they seem to enjoy sex with much more than with each other. Otherwise, Bonobos show a colony pattern like other primate groups, in which makes form a periphery with females in the core. But that core is the dominant part of the colony. It is extremely amusing to watch them constantly getting it on! Sex to quell aggressions when they're hungry. Sex when they find food. Sex while they eat. Sex to celebrate having had food. Sex to celebrate having chased of an intruder. Sex for no reason at all. Btw, I absolutely love this lecture series!
40:20 - 40:35 What book? The Jungle book?
Chastity belts likely never really existed in the way they have been imagined. There is an article on Atlas Obscura.
