Neuroscience, Decision-making, and Strippers


Decision making: there are countless books about it because, lets face it, decisions are at the epicenter of what we humans do. Make the wrong choice and it can kill you, or at least cause a lot of sweat and tears.

One major crossroads for many involves mate selection. Some knock it out of the park—we’ve all seen the heartwarming stories of couples still in love after 50 years—and then there are the marriages that crumble after a few months, or even days.

So what can we learn from the long-term lovebirds? What’s their secret? How did they find each other? When you first meet someone, what are the telltale signs to look for and, perhaps more importantly, to avoid?

It’s classic advice column fodder, and people make a tidy living doling out their strategies for selection. But at the crucial moment, how much strategy is really involved?

In his book Incognito: the Secret Lives of the Brain, neuroscientist David Eagleman shares an unlikely experiment done in New Mexico.

Scientists were curious about how someone's attraction response to a woman might be influenced by her fertility. It’s a tricky thing to study: how do you quantify something as ephemeral as human sexual chemistry? For these particular researchers, the answer lay in strip clubs. If the two things were connected, they hypothesized, maybe a lap dancer’s nightly tips would ebb and flow with her menstrual cycle?

The results were surprising. Lap dancers during their peak fertility period earned a cool $68 a night. On evenings they were menstruating, their tips fell to $35, for a monthly average of about $53.

Those who were on the pill saw no such fluctuation. Instead, they averaged about $37 dollars an evening.

What accounts for the difference? Of course, there’s no way to be sure. But Eagleman speculates it has to do with subtle changes in things like body odor, complexion, and waist-to hip ratio. It might also involve the output of pheromones, those neural chemicals linked to attraction, picked up subconsciously through the nose.

In other words, without realizing it, strip club patrons were primed to open their wallets and give more freely. They took their cues from the most primitive parts of their brains, hardwired over the generations to notice potential mates with the greatest likelihood of producing offspring.

No rational decision-making was at work, no reference to a conscious list of preferred attributes. Consciousness wasn’t even invited to the party.

What does all this mean? Well, if you’re a lap dancer relying on those tips, it means doubling up on your shift during peak fertility and maybe looking at alternate forms of birth control.

If you’re a man trying to pick up women, it means you might want to second-guess that gut instinct. Ask yourself, ‘who’s driving?’ It might not be who you think.

The Robert Frost Quandary, or How Irrational Thinking Might Save Your Life

Image
You stumble out of the wilderness, having had no contact with humans for at least ten days. You’re weak from hunger and fatigue and you find yourself at a crossroads, power lines stretching out along each of the separate roadways. It’s decision time. You think about Robert Frost’s poem, and wonder if his advice to take the road less traveled might not just lead to your demise. What do you do, or more importantly, which brain system should you use to make this crucial decision? Daniel Kahneman, famed psychologist, winner of the Nobel prize for prospect theory and author of Thinking Fast and Thinking Slow might be the one guy to call, assuming your existential crossroads gets cellphone reception. Kahneman explains that we have two systems for making decisions. He refers to them simply as System 1 and System 2. System 1 is reflexive, automatic, and impulsive. It takes a constant reading of your surroundings and generates short-term predictions, all operating on a level beneath yo

Who Are You: Does Personality Change as We Age?

Image
Are you the same “you” that you were twenty years ago? Thirty? Forty? What about fifty years ago? While science still struggles to quantify, measure, and categorize personality, some have a different question: how stable is personality in the first place? Do the high school version of yourself and the retiree version of yourself still have some common immutable core? It depends how you look at it , says a paper by lead author Rodica Damian of University of Houston and her co-authors Marion Spengler of the University of Tuebingen in Germany, Brent W. Roberts of the University of Illinois at Urbana-Champaign, and UH grad student Andreea Sutu. The paper in question goes by the catchy title “Sixteen going on sixty-six: A longitudinal study of personality stability and change across 50 years.” Damian and her colleagues compared the results for 1,795 U.S. adults who had taken a personality test as teenagers and then again, five decades years later. The team found that yes, there is a

The Best Painkiller Isn't What You Think It Is

When we say that listening to the right song makes us feel better, usually we mean it in terms of emotions. However, a new study from the University of Utah Health suggests that combining certain painkillers with certain music boosts the pain-fighting effect of the medication a measurable amount. This recent bit of research was conducted specifically on models recreating two types of pain: inflammatory and post-surgical. (Nerve pain, or neuropathic pain, was not addressed.) Low doses of four medications were explored: ibuprofen, cannabidiol, levetiracetam, and NAX 5055. As for music, the researchers went with one artist only, while the control groups were given one of the four drugs and subjected to white noise. What music would you choose for optimal painkilling effect? The experimenters went with Mozart. (Interestingly, the phrase “Mozart therapy” already exists, referring to the beneficial effect ol’ Amadeus can have on patients with epilepsy. For instance, a 2018 st
