Expertise in subjunctive scaling of declarative fractions

University College of London researchers John Jerram and Nikki Shure have evidence that rich North American men are the most likely to employ bullshit:

Study participants were asked to assess their knowledge of 16 math topics on a five-point scale ranging from “never heard of it” to “know it well, understand the concept.” Crucially, three of those topics were complete fabrications: “proper numbers,” “subjunctive scaling” and “declarative fractions.” Those who said they were knowledgeable about the fictitious topics were categorized as BSers.

Using a data set spanning nine predominantly English-speaking countries, researchers delineated a number of key findings. First, men are much more likely than women to master the art of hyperbole, as are the wealthy relative to the poor or middle class. North Americans, meanwhile, tend to slip into this behavior more readily than English speakers in other parts of the globe. And if there were a world championship, as a true devotee might appreciate, the title would go to Canada, data show.

Finally, a between-country comparison finds that young people in Canada and the United States are the most likely to over-sell themselves overall, with those in Europe being much less likely to engage in such behavior.

Taken as a whole, the results appear to suggest that the countries with the greatest propensity toward bombast also have the smallest variances between groups living within them. In the U.S. and Canada, for instance, there may simply be so much BS going around that everyone ends up partaking in it.

Lunchtime reading

I had these lined up to read at lunchtime:

Meanwhile, for only the second time in four weeks, we can see sun outside the office windows:

Home sick and tired

I'm under the weather today, which has helped me catch up on all these stories that I haven't gotten to yet:

And now, I will nap.

Detecting Alzheimer's in a novel

Researchers used the Iris Murdoch's last novel to quantify how Alzheimer's first signs show up in language:

As [neurologist Peter] Garrard explains, a patient’s vocabulary becomes restricted, and they use fewer words that are specific labels and more words that are general labels. For example, it’s not incorrect to call a golden retriever an “animal,” though it is less accurate than calling it a retriever or even a dog. Alzheimer’s patients would be far more likely to call a retriever a “dog” or an “animal” than “retriever” or “Fred.” In addition, Garrard adds, the words Alzheimer’s patients lose tend to appear less frequently in everyday English than words they keep — an abstract noun like “metamorphosis” might be replaced by “change” or “go.”

Researchers also found the use of specific words decreases and the noun-to-verb ratio changes as more “low image” verbs (be, come, do, get, give, go, have) and indefinite nouns (thing, something, anything, nothing) are used in place of their more unusual brethren. The use of the passive voice falls off markedly as well. People also use more pauses, Garrard says, as “they fish around for words.”

For his analysis of Murdoch, Garrard used a program called Concordance to count word tokens and types in samples of text from three of her novels: her first published effort, Under the Net; a mid-career highlight, The Sea, The Sea, which won the Booker prize in 1978; and her final effort, Jackson’s Dilemma. He found that Murdoch’s vocabulary was significantly reduced in her last book — “it had become very generic,” he says — as compared to the samples from her two earlier books.

Apparently there's a movie about Iris Murdoch too.

One measure of stiffening support for Trump

New research suggests that men insecure about their masculinity tend to support the president more. No, really:

We found that support for Trump in the 2016 election was higher in areas that had more searches for topics such as “erectile dysfunction.” Moreover, this relationship persisted after accounting for demographic attributes in media markets, such as education levels and racial composition, as well as searches for topics unrelated to fragile masculinity, such as “breast augmentation” and “menopause.”

In contrast, fragile masculinity was not associated with support for Mitt Romney in 2012 or support for John McCain in 2008 — suggesting that the correlation of fragile masculinity and voting in presidential elections was distinctively stronger in 2016.

The same finding emerged in 2018. We estimated levels of fragile masculinity in every U.S. congressional district based on levels in the media markets with which districts overlap.

[I]t remains to be seen whether any link between fragile masculinity and voting will persist after Trump exits the national stage. We suspect, however, that Trump’s re-engineering of the GOP as a party inextricably tied to many Americans’ identity concerns — whether based on race, religion or gender — will ensure that fragile masculinity remains a force in politics.

Again, it's not the size of the correlation that matters, it's how we use the data.

It's not "he said, she said"

Writing in Forbes, psychologist Todd Essig says it's perfectly plausible that Brett Kavanaugh has no recollection of what to Christine Blasey Ford was a life-changing event:

It is distinctly possible that his lack of memory is not because it never happened but because he really has no recollection of it taking place. He never encoded the event. Therefore, he cannot remember something he never noticed, even though it proved to be life-altering for someone else.

As Dr. Richard Friedman wrote this week, an attack usually triggers intense emotions and stress hormones that facilitate encoding memories. That is why “you can easily forget where you put your smartphone or what you had for dinner last night or last year. But you will almost never forget who raped you, whether it happened yesterday — or 36 years ago.”

Of course, this doesn’t let [Kavanaugh] off the hook for what he did or at all suggest he either has or doesn’t have the qualities one needs in a Supreme Court Justice. It’s just that he may not be lying about what he recalls. It also doesn’t excuse the self-serving way he transformed the absence of memory into the presence of certainty that something didn’t happen. A judge should know better than to rest his career on such a logical incongruity.

For another take on this phenomenon, check out Deborah Copaken's moving essay in The Atlantic, "My Rapist Apologized."

Women's voices have changed

That's the conclusion of a researcher at the University of South Australia:

Cecilia Pemberton at the University of South Australia studied the voices of two groups of Australian women aged 18–25 years. The researchers compared archival recordings of women talking in 1945 with more recent recordings taken in the early 1990s. The team found that the “fundamental frequency” had dropped by 23 Hz over five decades – from an average of 229 Hz (roughly an A# below middle C) to 206 Hz (roughly a G#). That’s a significant, audible difference. 

The researchers had carefully selected their samples to control for any potential demographic factors: the women were all university students and none of them smoked. The team also considered the fact that members of the more recent group from the 1990s were using the contraceptive pill, which could have led to hormonal changes that could have altered the vocal chords. Yet the drop in pitch remained even when the team excluded those women from their sample.

Instead, the researchers speculated that the transformation reflects the rise of women to more prominent roles in society, leading them to adopt a deeper tone to project authority and dominance in the workplace.

I have a lot of friends who might agree; some of them sing soprano and speak tenor. No joke.

Parker update

We just got back from the vet. The x-rays show that Parker's leg is almost completely healed, so he's finally cleared to go back to his play group. He has no idea about this right now but tomorrow morning he'll be very, very happy.

Now I'm about to run to my office, so I'm queuing up these articles to read later:

OK. Chugging some tea, and hitting the CTA. More later.

Where to start?

And now, a stand-up meeting.
