Are you asking if old findings are reconsidered based on the growth of population? Regardless of the size of the overall population, any study must take into account a large enough population to be statistically relevant. Once that has been achieved, the overall population size doesn't matter, generally. For instance, studies that talk about the spread of polio and the efficacy of the polio vaccine should stay somewhat reliable. I'm assuming that some of the data on spread talks about different population densities. So, as the overall population size increases there may be more, higher density pockets of population which will result in even more people getting infected, but shouldn't automatically change the prior findings. That said, other variables can and do change, so there could always be the need for newer studies to quantify the impact of those changes. Maybe climate change and deforestation have some impact on polio and/or it has mutated in some way.

Studies that are very specific about a particular population and its size may well need to be reconsidered as that population changes both in makeup and size.

I personally believe that 'good science' is always going to at least consider the impact of population growth/change even if it's unlikely that it would have much, if any, impact.

    Because I used to get an uneasy feeling around some people that turned out to have some psychopatic tendencies and them not doing the baby voice when talking to a dog was something they had in common. Not sure if its coincidence or not. Hence the curiosity whether there's research about that.

    The recordings have been public for 20 years now,

    https://www.bps.org.uk/research-digest/newly-analysed-recording-challenges-zimbardos-account-his-infamous-prison

    But just read the "boring" stuff, studies and articles from respectable institutions.

    Very very few people on TV or making online videos understand anything they skimmed and are regurgitating.

    But that's still just the surface, the only reason he finally called it off was one of his grad students threatened to stop sleeping with him because it weirded her out how he'd talk about it after sex...

    I do remember learning about the Stanford Prison experiement, but I was not aware of what Zimbardo did. Lol ok fair enough, I accept your answers. What are some good online sources for psychology research, for future reference?

    Early 1970s psychology was crazy, but it stayed in highschool textbooks well into the 00s, and even today people learn about the Standford Prison experiment, but not the part where Zimbardo forced the guards to be cruel and prevented prisoners from leaving even when their parents threatened to get the cops.

    He just manipulated everyone into it, and then said everyone else was a monster....

    But the point of that example, is if you're even remotely interested in psychology, read actual research or at least good articles about it

    There's so much fascinating and actually useful shit out there now.

    Just don't get it where ever you have been lol.

    The same reason anyone does...

    Either they're naturally high pitched or they're pleasing for something. Raising pitch when pleading is something literally everyone does.

    Like "psychopath" isn't even a diagnosis anymore, it's not a real thing.

    There's ASPD (anti social personality disorder) but all that is, is a broken oxytocin system either due to nature or nurture. And when considering how many people commit "crimes of passion", I'd be surprised if people with ASPD commit more crimes than others.

    The reason it's over-represented in prison populations (~25%) is just because almost everyone in prison is either stupid or has bad risk assessment. Someone who also doesn't have an inmate issue with violating societal norms, doesn't have any guiderails. They're most likely going to end up in prison.

    But people latching on ASPD like those people are dangerous and constantly taking advantage of others is no different than stories about witches and monsters from centuries ago. Stories told to make people feel safe as long as they can identify "them" and everyone else is "safe".

    Like, the oxytocin system is why people live their in group, but it's also the entire fucking reason for "out-group" in the first place. It's pure tribalism in a biochemical.

    Someone with ASPD doesn't have innate in-group bonds, but the vast majority are smart enough to figure societal laws are beneficial. And they just don't have it in them to be racist.

    So don't worry about "psychopaths" worry about idiots with bad risk assessment, most of the damage they do is because they legitimately think they're helping somehow.

    Edit for a reference:

    However, research by professor Carsten de Dreu at the University of Amsterdam showed in 2011 that oxytocin had a slightly more sinister side. His experiments revealed that what many thought of as the “moral molecule” actually contributed to what scientists euphemistically refer to as “ethnocentrism,” or what the layman would call racism.

    Participants in de Dreu’s study were presented with a dilemma in which they had to deny one person access to a lifeboat in order to save five others. In the double-blind experiment, Dutch men were given either oxytocin via a nasal spray or a placebo. The results showed that those taking oxytocin were more likely to spare men with Dutch names while sacrificing those with Muslim- or German-sounding names. For those who were given the placebo, however, the name of the potential victim didn’t matter.

    I I found it strange that this hormone, which supposedly makes you love everything around you, also apparently turns you into that very specific type of dickhead who chooses to be hostile to those who are different from you. So to find out more, I got in touch with Anil Seth, a neuroscientist at the University of Sussex and co-director of the Sackler Centre for Consciousness Science. He said that this effect of oxytocin could have something to do evolution and social survival.

    “The idea of altruism and pro-sociality has been looked at a lot by anthropologists and social scientists who recognize that while it often pays to be pro-social among your in-group—those who share common cultural interests and who may even be distantly related to you—the opposite might apply with your out-group,” he told me

    Ok, fair enough.

    Question, why would a psychopath have a dog voice if not for the sake of mimicry? I'd imagine that speaking to a dog that way would require some kind of empathy or at least emotion towards the dog.

    It's specific enough, that there probably hasn't been,

    Consider why neurotypical people do it. One theory, that's around, is that it's because babies can hear higher registers better. If so, a psychopath might still have the same instinct, because that doesn't seem directly related to guilt or empathy. They also would be exposed to people around them doing it.

    On the other hand, they're never going to pity an animal, which might be the entry point to caring about them as if they were offspring.

    What makes you think they wouldn't?

    Go look up clips of Charles Manson and tell me whether you think he could do a baby voice.

    Lots of other psychopaths and sociopaths are good at being manipulative, and talking in a baby voice is a very easily learned behavior to appear normal.

    Thanks for the update! Those are some weird results. I don’t think tape temperature would matter - there is so little mass there that, even if it was warm when you put it on, it wouldn’t have an appreciable effect on the temperature of the handle, and I would think that its temperature would equalize pretty quickly… but maybe a minute isn’t long enough for that?

    You may have addressed this already, but does the door have an electric lock?
