    I suspect optimism is learned to some extent. Past experiences and outcomes shape your optimism, because it skews your bias.

    People who had good things happen and got lucky get more optimistic as that's their experience.

    If true, it might be that good genetics and environment gives you exceptional longevity, and also increases your chances of good outcomes at every step of your life which in turn make you an optimist.

    Off course, I'd love to believe it's your mindset that affects outcomes, as it would give you control over your destiny, but it's precisely because that truth is so tempting that I'm extra skeptical of it.

    • dleary 17 hours ago
      This sounds like it should be true, but from life experience, I don't really think it is.

      It would be rational for things to work that way, but personalities and emotions are not very rational.

      There are some people who seem like they have everything in life going for them, and they're still pessimists, their narrative of the world is petty and ugly, or cruel.

      Conversely, there are other people who have suffered tragedies that I might consider literally unbearable (i.e. suicide-worthy), and they are still optimists.

      I think these are more fundamental personality traits. You can see it in siblings that grow up in essentially identical conditions, but one has a "sunny disposition" and another is anxious and worried.

      Dissatisfying take: It's both true and untrue.

      Your mindset absolutely has an influence on outcomes - how you come off to other people influences how they react to you and treat you. How you look at a problem influences whether you decide to engage with it, and how.

      This exists in a gradient space - some things are more readily influenced in this way, others are not, a few are (nearly) completely untouched.

      Existence, that is - the Universe, is a complex system. We know at least a few things about those:

      - they behave in unintuitive ways. Attempting to predict the behavior of a complex system has an inverse relationship with the granularity and specificity of the prediction.

      - the behavior of the whole is unrepresentable in the behavior of the constituent parts (you cannot drive an axle to work, unless it is part of a car)

      - they are very resilient against attempts at control, but more susceptible to influence

      - they can exhibit features like recursion, inertia, and attraction. Each of these has specific consequences for the behavior of the whole.

      The relationship between outlook and outcome is bidirectional - one influences the other and vice versa. This structure has a high chance to exhibit recursive reinforcement, which is why I think we're used to seeing very optimistic and very pessimistic outlooks, with not so many 'middle-of-the-road' types. It does provide a lever to push, however, if one has the fortitude to push through the failures on the way to that tipping point.

      I shouldn't be here, the first 20 years of my life were essentially every bad thing, defective body, I had my first birthday party at 30, dead parents, stolen and exploited childhood, moving all the time, constant mortality threat, surgery induced aphantasia, waking surgeries scenarios that spiral some adults into ptsd. Long term thwarted desires because I couldn't get health insurance without being a wage slave pre ACA. Co-founded my own succesful company the moment I could get ACA.

      I have a brain and as my wife once told me in a moment of frustration.

      "You're just happy to be here" and that is true. I didn't ask to be born and I've generally not enjoyed it, I'm only here because random luck geographically and temporarily allowed me to just squeak by surviving childhood and adolescents, I am a few years away from a cardiological surgery I could easily die in.

      But, it's all so damn funny isn't it, what an odd thing to be alive, a little cluster of atoms arranged human wise. I hope I die not having achieved what I want to achieve, I hope, like sharks, I never keep moving.

      Humans generate meaning, we are the known, empirically observed generators of the mosy complex meaning in existence and we still don't know and haven't created most stuff, it's early days yet. In the meantime, we're part of the entropic cycle, and we emit meaning the way stars emit photons.

      People will say we aren't special, but we are, special and rare and should be preserved, dolphins, et all should be too, but let it be observed that it will be humans and not dolphins that deflect asteroids for the foreseeable future.

      Many times when things got bad I thought I'd kill myself, I woke up from so many surgeries I started getting disappointed when I'd wake up, but I was too damn curious about what happens next, I can always end it tomorrow, nbd, I look forward to the perma nap, I'm an accident that shouldn't exist and I can exert casual leverage on the world with mere speech.

      Who knows what the future holds, let's give dolphins thumbs, let's give silicon rockets to explore the universe, let's engineer long life so we can start worrying about solving entropy instead of whether or not a single spinning rocks "mid air collision" or 5 degree increase in temperature will cause total societal collapse and put an end to our weird little epicenter of meaning generation.

      Maybe we solve entropy, maybe we figure out how to change the topology of spacetime, maybe we don't, it's too early to tell.

      Optimism is just the headspace to try again, it's not emotional ignorance, it's not positivity, it's the curiosity to keep trying new experiments, and the humility to not be intellectually certain of despair.

      • amatecha 15 hours ago
        I like your post, as it exhibits a sentiment I can relate to (though I have had a FAR smoother existence than what you've experienced, thus far, I think). I hope you have a rewarding future and I hope that luck is on your side with that upcoming risky surgery.

        To me, optimism is a form of acceptance of whatever may come. I will deal with whatever comes my way, and in the meantime, I will expect and work towards "the best" outcomes. Assuming/expecting the worst just adds friction and stress to my consciousness which serves no practical purpose. Why experience the bad things before they even happen? I face stressful "could go either way" situations with the mentality that it will work out, but I am fully ready to deal with the situation going as badly as it could. I prepare mentally for the bad outcomes, but don't dwell on it like many people seem to. It's just not worth it. I figured this out as a kid and developed that way of thinking throughout my life, refining and reinforcing it over time.

        I've now outlived a number of friends who I just assumed would always be there to talk to. They died totally unexpectedly, heart attacks and stuff like that. The journey could be over at any moment. I recognize and accept the temporality of everyone in my life including myself, and I actually use this acknowledgement to motivate myself to embrace the opportunity of life and not waste time on stupid bullshit, including thinking negatively or dwelling on fear-based lines of thought. It's like a basic judgment I apply to almost everything I think about, just passively, and it's a great filter to optimize for spending time on things that I think enrich my life (or future life) and that of those around me who I care about.

    Everything I've learned from psychology (and by this I mean watching psychology lectures from Yale and Stanford on youtube and reading the associated textbooks) makes me confident that I will have a short and unhappy life.

    Dr Bloom spoke about how your overall mood during college is a good predictor for how happy you'll be as a person throughout your life. He talked about the optimum time to get married is 26. He elucidated the idea of your prefrontal cortex solidifying around 25, making personality changes MUCH more difficult.

    Dr Sopolsky spoke about biological markers that may affect human behavior - both inherited and environmentally influenced.

    At 35 I am starting to suspect that I may be on the spectrum ( I kinda expected some adult to tell me this as a child, if it's true ).

    The males on my fathers side (with the exception of my uncle) do not make it past 67.

    My mothers side has inter-generational trauma that I know i've inherited avoidant behaviors that limit my social ability.

    So great news.

    • y-curious 31 minutes ago
      It sounds like therapy would be really nice for you, but here are my 2 cents.

      1. I have never been more depressed as I was in grad school. My life has gotten way better and stayed there after college.

      2. I got married at 30 and I have friends that got married older. This same statistical logic is what you hear about marriage (52% divorce!). What you don’t hear in that statistic is that a lot of people make terrible decisions. My point is that not being married early is a proxy for having a bad attitude, which I suspect they’re really measuring.

      3. Intergenerational trauma may be a thing, but you have tools at your disposal. Cognitive behavioral therapy is something I stand behind and recommend to you personally.

      Just remember: things won’t change in your life without faith that they will change

      Welp, I guess I'm dead then.

      >around 25, making personality changes MUCH more difficult

      Maybe it's just me but my personality keeps changing every year or so, based on the positive and negative experiences and challenges from living abroad alone, having to always adapt to new stuff to stay mentally, financially and socially afloat.

      I assume it's different if you spend your whole life in the same place you grew up in with the same people doing the same things. Maybe the brain checks out from the repetition.

      >avoidant behaviors that limit my social ability

      Move aboard to another country where you don't speak the language.

      • HEmanZ 1 day ago
        If it’s true then this is a propensity and not a rule.

        My mood in college was suicidal. My mood by my 30s was better than most people I’ve ever met (sans hiccup from a year of no sleep with a newborn).

        Looking back my horrible mood in college was probably caused by isolation, no sleep, high pressure course load, and too much alcohol. And I’ve noticed my mood drops dramatically when I get it in my head that I need to be more successful, at any point in my life.

      • hiAndrewQuinn 23 hours ago
        It's probably you! My personality has been basically the same since I was 4. I also live abroad and have for the past 5 years, though, so I guess I just lucked out and got a personality that works well in most conditions and with most people.
    • bix6 23 hours ago
      67 is still almost 7 decades of life!

      What’re you doing for fun?

      I was miserable in college but I’ve made significant changes since that have made me way happier.

      I think changes are possible at any stage of life. They just might require more commitment since we’re so spongy as kids.

      • f1shy 22 hours ago
        This is also my experience. I was miserable from 13 until 35yo. Then made big changes.

        I think it is extremely dangerous to make that affirmations, that may take away any hope some depressed folk may have, being 25 and having a hard time.

        The rationale about 25 years and the cortex should be much better explained, I think.

      > He elucidated the idea of your prefrontal cortex solidifying around 25, making personality changes MUCH more difficult.

      It’s true that neuroplasticity tends to decline around this age, but there are several important caveats:

      - Exercise, especially cardiovascular exercise, promotes the release of BDNF (brain-derived neurotrophic factor), which enhances neuroplasticity. Consistency matters, regular aerobic activity raises baseline BDNF levels, while sporadic exercise only causes short-term spikes. Studies even show that long-term cardiovascular exercise can alter brain structure.

      - Belief in your ability to learn is associated with better learning outcomes and higher neuroplasticity markers. Whether this comes directly from belief or from the behaviors it encourages, it’s still practical advice. Don’t entertain thoughts that you can’t adapt or learn -- especially during exercise.

      - Psychedelic experiences (with substances such as psilocybin, ketamine, or LSD) can open what’s called an “acute neuroplastic window”. During this time, brain network dynamics become more flexible and neuroplasticity increases. Surround yourself with the right people, ideas, books, during this period, and it can lead to dramatic positive change. But as this state can amplify both constructive and destructive influences, proceed with care and good research.

    • 80hd 1 day ago
      There's nothing wrong with being unhappy, IMO - you can still channel those emotions into something meaningful.

      But if you do want to be happy, you can find stories, if you look hard and long enough, of "outliers". People who, against all odds, defied "statistics" and broke out of whatever expectations society and "facts" projected onto them.

      I tried "everything" until age ~27 when I finally found one dial (very specific elimination diet) that made the rest of my body act mostly normally. Other changes were easier to make from that point onwards, altho there's a lot of damage to undo still. Diet is just one factor, for others it could be completely different.

      My point is - I thought I would never be healthy. This stuff runs in my family too. But I just kept trying things. There's no other option.

      You are a unique human being and soul who has something valuable to contribute to this world. Even if that's being unhappy.

      Hope that doesn't sound condescending, it's something I tell myself too.

      Have these males exercised for about 2-3 hours per week? If no, and you do not have this consistency too, that's one thing that's relatively simple to add to your life, which will also increase your overall happiness. That alone probably adds another 5 years and pushes your healthy lifespan forward too.

    • jimbokun 22 hours ago

      Some of this sounds more like ideology and less science, especially when deterministic tendencies are getting mixed up when talking about psychology.

      ...which is bunk; the studies that are cited as showing this actually showed changes in the prefrontal cortex up to the oldest people in their study, which was 25-year-olds.

      Current research suggests that it continues changing throughout our lives.

      Social media like all addictions fulfill needs that you can't satisfy other ways in your current state. Mostly human contact and validation.

      If you start getting out there and communicating with real people on intimate level - most addictions melt away by itself.

      It makes more sense to focus on the root cause instead of fighting the symptoms.

      • HEmanZ 1 day ago
        I disagree. Looking inward at myself at outward at addicted friends and family it does not fill any need.

        What it does is “hooks the attention” using outrage and a constant stream of dopamine hits.

        “ If you start getting out there and communicating with real people on intimate level - most addictions melt away by itself.”

        I highly suspect you are not an addiction specialist…

        • unionjack22 20 hours ago
          It can be both. The further away I get from social media and its singular narratives where it’s always “this ONE thing” form of causeality, the more I realize the mechanisms and causes can be multimodal and compound upon on another.

      It might also be something like: people who experience relatively little psychological distress are optimistic, and also live longer.

      We don't like to talk about it, but there is a biological component to how happy or anxious someone is. Not to say that everyone is doomed to be a certain way because of their genetics, but I've known people who are basically never sad, and it's not because they've found some kind of secret of happiness. I have a friend who has the temperament of a golden retriever.

    • coldtea 23 hours ago
      Or less stressing about things and giving less fucks causes longevity.

      Which makes even more sense, since stress affects all cause mortality and all kinds of outcomes, and even mere positive disposition towards a treatment is found to make a big difference in patients.

  • OutOfHere 22 hours ago
    This seems like a rather obvious case of "correlation is not causation". Moreover, the vocabulary of optimism vs pessimism doesn't capture that one can work diligently to avoid pessimistic outcomes, so does that make one optimistic or pessimistic? After adjusting for the correlation, I suspect realists will have the highest longevity.
