Evo psych: Watching porn for science

Spread the love

From Steven Hayward at Powerline: … this article actually appears in the current issue of Evolutionary Psychological Science:

Duration of Cunnilingus Predicts Estimated Ejaculate Volume in Humans: a Content Analysis of Pornography

Abstract

Humans perform copulatory behaviors that do not contribute directly to reproduction (e.g., cunnilingus, prolonged copulation). We conducted a content analysis of pornography to investigate whether such behaviors might contribute indirectly to reproduction by influencing ejaculate volume—an indicator of ejaculate quality. We coded 100 professional pornography scenes depicting the same male actor copulating with 100 different females, affording control for between-male differences in estimated ejaculate volume. … (public access)

Hayward:

A few observations. First, it sounds like a fancy excuse for a bunch of pervs to watch a lot of porn under the guise of “science,” along the way proving there’s no subject that academics can’t ruin for everyone. … Fourth, like most scientific findings, doesn’t this study need to be replicated? (Good news for college fraternities everywhere, not to mention the unemployed Anthony Weiner.) Can we please have the full list of titles that were viewed? More.

We’re not surprised. Social sciences are mostly nonsense anyway. Evolutionary psychology is the most nonsensical of the lot because it is a discipline without a subject. There are no early humans to study, and just about everything published is based on unfalsifiable nonsense using the preoccupations of modern Western society and the terminology of evolutionary biology.

For example,

Evo psych also accounts for anger over trivial matters (it was once key to our survival), dreams (they increase reproductive fitness), false memories, (there might be a tiger in that tall grass…), menopause (men pursuing younger women), monogamy (control of females or else infanticide prevention — of one’s own children only), music (to ward off danger), premenstrual syndrome (breaks up infertile relationships), romantic love (not an emotion, rather a hardwired drive to reproduce), rumination on hurt feelings (our brains evolved to learn quickly from bad experiences but slowly from the good ones), smiling (earlier, a cringe reaction), and wonder at the universe (explained by how early man lived).

It feels like emptying Darwin’s wastebasket.

Actually, we hear less about evo psych these days from the pop science media; fading interest may account for the Springer article noted above. It’ll get shares, tweets, ink.

    Watching porn and getting paid. It’s good work if you can get it.

    Disturbing stuff. Not sure how you can call it science or what the purpose of it is.

    Evolution cannot produce morals and this is a good example!

    Porn Changes the Brain – August 8, 2014
    Excerpt: Just like other addictive substances, porn floods the brain with dopamine. [7] But since the brain gets overwhelmed by the constant overload of chemicals that comes with consistent porn use, it fights back by taking away some of its dopamine receptors [8]—which are like tiny ears on the end of a neuron that hear dopamine’s message.

    With fewer receptors, even if the brain is putting off the same levels of dopamine in response to porn, the user can’t feel dopamine’s effect as much. [9] As a result, the porn they were looking at doesn’t seem as arousing or exciting, and many porn users go hunting for more porn or more hardcore porn to get the effect the old porn used to offer. [10]

    As a frequent porn user’s brain acclimates to the new levels of dopamine flooding through it, regular activities that would normally set off a burst of dopamine and make the person feel happy aren’t strong enough to register much anymore, leaving the user feeling down or uneasy whenever they go for a while without looking at porn. [11] That’s one reason why pornography can be so addictive. [12] (See Porn is Addictive)

    Once addiction sets in, the user has a whole new set of problems, because addiction damages the part of the brain that helps you think things through to make good choices—the brain’s limit setting system. [13] For more than 10 years, studies have shown that drug addictions can cause the brain’s frontal lobes to start shrinking. [14] While “frontal lobe” sounds really technical, basically it’s the part of the brain that controls logical problem solving and decision making. [15] But recent studies have found that it’s not just drugs that cause that kind of damage—the same problems show up with other kinds of addictions, such as overeating, Internet addictions, and sexual compulsion. [16]

    And here’s the really scary part: the more porn a person looks at, the more severe the damage to their brain becomes and the more difficult it is to break free. [17] But there’s good news too: neuroplasticity works both ways. That means that the damage to the brain can be undone when someone gets away from unhealthy behaviors.

    The Science

    So you’re probably asking at this point, how is it that someone who so compulsively needs to view sex on a computer screen has no interest in (and ability to have) sex in real life?

    Time to drop some knowledge.

    Porn promises a virtual world filled with endless sex—more sex, better sex, different types of sex. What it doesn’t mention, however, is that the further a user goes into that fantasy world, the more likely their reality is to become just the opposite. Porn often leads to less sex and less satisfying sex. And for many users, like in the story above, porn eventually means no sex at all.

    Verses:

    Matthew 5:28
    But I tell you that anyone who looks at a woman lustfully has already committed adultery with her in his heart.

    John 8
    34 Jesus answered them, Verily, verily, I say unto you, Every one that committeth sin is the bondservant of sin. 35 And the bondservant abideth not in the house for ever: the son abideth for ever. 36 If therefore the Son shall make you free, ye shall be free indeed.

    What I don’t understand is how watching a video of an individual where the video is not made for science but for entertainment can possibly tell you anything about biology at all.

    Second, what I don’t understand is how actual science can get removed for being associated with ID, but this stuff remains. It is ridiculous. Science is becoming a parody of itself, and it is sad.
