[@philj8205]

​@@TheSapphireLeo Education is incredibly beneficial. Yes, a lot of educators do a terrible job and do more harm than good, but if you are comparing some of the atrocious systems we have set up in our K-12 public school system with a lecture from Stanford then that is a pretty stupid comparison to make and depending on your teachers there was plenty of value to be had in K-12 education as well. I can't imagine going back to school at 35 to take advanced mathematics courses in my CS degree if I never was forced to go to school. They *have* to force you to. What kid is going to willingly choose to go to school? Many things about childhood are forced upon you for your own benefit later on in life.

"a relationship is the price you pay for the anticipation of it" might be the hardest line ever said in a stanford lecture hall

[@bill482]

I began to question 'sexual addiction' as a cultural norm. I quickly realized I and mentors in my life had been unaware of our sexual addiction, womanizing, or seeing the 'other' as an object to be exploited sexually. This destructive behavior is rampant in our culture. It is just one of many addictions. Attempting to build a life around a sexual lifestyle is like trying to build a life around eating meals, or drinking, or smoking dope all day. It is an addictive behavior awash with suffering and loss. I was fortunate and began to find that happiness I had been pursuing... within my own being. Seeking happiness in the field of sensual fulfillment (be it drink, drugs, sex, wealth, or power) is destined to fail. Happiness is one's birthright. Happiness is one's nature. Be like a little child and walk in happiness, that is what I have come to live.

15:12 If anyone is wondering what Mr. Saposlky is refering to here (what he adresses his students to look at the extended notes), he is refering to Randomized Responding, a technique invented by Joel Cohen. It works something like this: suppose 10% of the population does Sexual Behavior A and hesitates to admit that. Give people the questionaire asking about this in private with the instructions: a) if you have done Sexual Behavior A, indicate yes; b) if you have not, flip a coin; heads, say you have done A, tails, give the truthful answer of no. As a result 45% of people will say they have not; double that, and it tells you that 90% of people have not, 10% have, but anyone who was resistant to admitting the latter can claim their answer was coin toss-determined.

@@cyclopshot well, it's statistics. With large enough numbers you get a close enough estimation with this method (coin tossing tends to have a 50% chance of either heads or tails as more people do it) In inferential statistics you never get the actual, exact result, because in order to do that you'd need the whole world (7B humans) to be in your sample. You only estimate the actual proportions, and with large enough numbers you just "guess" that it's close to the actual thing.

At 27:49 he discusses how bad humans are at sexual monogamy. The novelty of something new vs the comfort of something familiar. 27:49 "Marriage. Clearly, we've heard about this monogamous, pair bonding species. And in terms of the formal structure of marriage it is universal. All human cultures have some version of it. Across all human cultures over 90% of people wind up in that cultures equivalent of a permanent stable relationship. And this is the case in polygamous cultures. We already heard that business. Even though historically the majority of human cultures have been polygamous. Nonetheless, amid them the vast majority of individuals have been in monogamous relationships. Amid that nonetheless, what is also clear amid that highly, highly prevalent pattern of monogamous relationships there's a lot less monogamy going around than you would think. And this was first sorted out with people like Alfred Kinsey first working out that questionniare approach to people's sexual behavior, what became clear was there's a lot less faith within pair bonding within the human species, with humans in this country and this is shown in all sorts of other societies than one would originally assume. There is "social monogamy" but not anywhere near a high of rates of "sexual monogamy". 29:10 "And what the paternity studies have shown is in most western European countries the rate at which children have been fathered by an individual other than the person claiming marriageable credit for doing so ranges between 10% and 40% of children."

I have 3 degrees & they came from a public university in the CA State University system. Never was I privileged enough to attend a lecture as deeply engaging as these. What is most striking to me is the superior level of education delivered. Attending students benefit from these exclusive Colleges/Professors & gain advantages most of us will never understand (until we see a lecture of this quality). My entire college experience would have been astoundingly different had I been able to attend a school of this magnitude. Unfortunately, I was a single parent raising 3 children & didn't have the ability to relocate & attend an upper-tier college. Some institutions are truly interested in providing exceptional, high-caliper teaching & others are interested in simply making money. Such a shame. The differences are startling ... shocking even ... and *wondrous*.

[@latinaalma1947]

Retired psych professor and administrator here. There are not any other Sapolskys...he is one of a kind. Professors are chosen not at all for their lecture skills...they are chosen at the beg. of careers for their publications in journal articles...quality of journals that publish their early articles. Then later as they move up from lecturer, assistant prof, assoc prof and full professor they are chosen for both the quality of publications by the prestige in their field of the journals in which they publish THEN the number of publications THEN of equal importance at some institutions the dollar amount of grants they bring in. The universities NEED the funds from these grants to subsidize the physical plant etc...overhead is charged on each grant substantial sums. Grants bring in a huge amount of money and the best universitites get the most funding from that source...professors bringing in those higher funded grants receive rewards...better facilities and labs, nicer offices, higher travel budgets, and eventually are chosen for funded chairs...which means their salary is supplemented by the university to the tune of $50 to 200,000 USD and up annually. Whether they are engaging lecturers just does not come into it to be totally truthful about the matter. At community colleges lecture skills ARE part of the equation since those institution never get large grants and their faculty rarely publish anything so the emphasis is on teaching skills BUT skills that make complex subjects more INTELLIGIBLE to less gifted students than Stanford students. Subjects like chemistry, microbiology, ie the hard sciences....especially as foundational courses. Did you hear him refer to Federal grant money in this lecture...yes that and industry grants are KEY to career advancement.

Dopamine: Is Activated when you're aroused/ attracted to something and during 'proceptivity'. Drives goal-directed behavior. Creates pleasure from anticipation of the reward. 42:44-44:06 (VTA> Nucleus Accumbens> other parts of the brain). If this mesolimbic dopamine pathway doesn't work in you, you'd not only lack sexual interest but will be depressed (lack confidence in your ability to do/get something well/great) DA Receptors: D1 is about the maintenance of the attachment/ pair bond D2 is about the formation of the attachment/ pair bond; first D2 is needed but then in the end D1 levels should return/rise for more stable attachments? I think this is what Dr. Sapolsky means. If this is the case, hence the importance for 'lovers' to embrace novelty, space/distance/time away from each other...so that the anticipation part is there (we can't be 'attracted' to something we are already much attached too, ironically, right?)

it means what one really wants is the anticipation of a relationship and all the rewards of feel-good when anticipating it, but to get that one ends up having to pay the price of committing a relationship afterward.

@hailey grey YES!! This is an absolute fact that I myself have personally experienced & physically felt during my own journey through heroin addiction, I still can find myself feeling a certain wave even simply thinking about heroin from my time during that period of my life. It's a crazy thing how our brains & all that's connected within them work & our behaviors that associate with such.

As a woman, my two cents on whether I think the female orgasm is spandrel, is that I do not think it is spandrel. I actually use my orgasm as one of the measures of whether or not a guy will make for a good long term partner because if he is thoughtful enough to take into account what pleasures me (and not just him) and actually has the patience to make me feel good enough to climax, then he is more caring and less selfish, and too me that is desirable in a man, so it'll make me want to seek something longer and more meaningful out with him above any other man.

[@mariidee2]

My thoughts exactly thank you for writing it out for me. It’s recently come to my attention that not all women do this, and are quite happy to be with a man who doesn’t make a woman climax. i just found out, 8/10 of my female friends do not climax during sex and several of them have never had an orgasm. I could not be in love with a man who does not engage in mutually enjoyable orgasm which is the definition of making love vs “having sex”. I’m gobsmacked as to what the goal orientated pay off is to partake in a relationship ??? If not to do experience mutual ecstasy and build a family around this.

[@lynxaway]

It was a very bizarre discussion to me overall in the lecture-is it not common sense that if the sex is enjoyable for both participants‚ it is more likely to be long-lasting and reoccurring and thus result in more reproduction?

[@g0dofwar706]

Makes sense. I tend to also have patience when in bed with someone i really like. And would last longer too, compared to just having sex after a night out lol

[@janbloxham4485]

It's dissapointing when Sapolsky at 28 mins states that studies show 10-40% of people have different fathers than their mothers claim. It's 10-40% of men that choose to have paternity tests done that turn out to not to be the father, a completely differnet group than "all men" - one that evidently has very good reasons to have a test done. About 4% of people have different fathers than the mother claims.
