Cultural Evolution and the Impending Singularity: The Movie

by Sean Roberts in A Replicated Typo 2.0

A video of a talk I gave at the Santa Fe Institute, asking questions like "Has Biological Evolution come to an end?", "Is belief an emergent property?", "Will advanced computers use humans as batteries?" and "Will robots spend more time playing the violin than solving science?"... Read more »

The curious relationship between place names and population density

by Tim De Chant in Per Square Mile

Giving a name to a place is an important act. It says a place has meaning, that it should be remembered. For thousands of years, the way we kept track of place names—or toponyms—was by using our memory. Today, we’re not nearly so limited, and the number of toponyms seems to have exploded. Yet oddly [...]... Read more »

Let me tell you a story…

by Rita Handrich in The Jury Room

Everyone loves to hear a good story.  And if you are reading our blog, you probably love to tell stories, too.  A good story is essential to effective communication and persuasion, and that sort of defines our wheel-house.  But I digress…  Sometimes stories are traditional “once upon a time” sorts of tales, but more often [...]

Friday Fun: At the Movies (with a Psychologist)

by Psych Your Mind in Psych Your Mind



source
Because Juli's psychology songs post was so much fun, I thought I'd try something new this Friday. In what follows, I will provide a very brief summary of the plot, or a specific scene, from a movie. After this description, I will then discuss a key psychological construct that the movie's theme relates to.



It's a simple game, so let's get started. There are spoilers, so read on with caution.

Get the Gist of How Jurors Decide Damage Numbers

by Persuasion Strategies in Persuasive Litigator

By Dr. Ken Broda-Bahm - "Well...let me just throw a number out to get us rolling: Five million dollars!" (Recent mock juror quote) Juror damage awards can seem erratic and inexplicable, not only to the public, but to experienced litigators as well. Particularly when jurors are valuing something other than a concrete expense by assessing non-economic or punitive damages, the process can seem driven by nothing more than caprice. One effect of mock trial research -- namely, the ability to watch jur........ Read more »

Well that settles it: income inequality really does go hand in hand with religion

by Tom Rees in Epiphenom

Long-time readers of this blog will know that the link between inequality and religion has a particular fascination for me. In fact, the blog started while I was doing background research into a paper I wrote in 2009, on the link between income inequality and religion in countries around the world.

The idea was first put forward in rough form in an earlier book by Pippa Norris and Ronald Ingelhart. My paper took that a modest step further, by showing that income inequality really did seem to be........ Read more »

Antipsychotics - The New Valium?

by Neuroskeptic in Neuroskeptic

Antipsychotics, originally designed to control the hallucinations and delusions seen in schizophrenia, have been expanding their domain in recent years. Nowadays, they're widely used in bipolar disorder, depression, and as a new paper reveals, increasingly in anxiety disorders as well.The authors, Comer et al, looked at the NAMCS survey, which provides yearly data on the use of medications in visits to office-based doctors across the USA.Back in 1996, just 10% of visits in which an anxiety diso........

Hunting Pathogens in Siberian Permafrost Graves

by Michelle Ziegler in Contagions

The Yakut community of Eastern Siberia has gained some attention from anthropologists because it culturally stands out from other Siberian populations. Their Turkic language, unique burial practices, and horse-breeding culture is not native to Siberia. Recent genetic analysis of 58 bodies preserved in permafrost from the last five centuries and 166 current members of the [...]... Read more »

I’m disgusted (until I wash my hands and feel purified)

by Doug Keene in The Jury Room

It’s not just Pontius Pilate and Lady MacBeth, all of us feel better with clean hands. The disgust literature is everywhere these days. As it turns out, disgust is a powerful emotional motivator. Researchers recently attempted to see if being even minimally involved in activities that brought participants into contact with religious beliefs different from their own [...]

What makes us musical animals? [Part 2]

by Henkjan Honing in Music Matters

We have known for some time that babies possess a keen perceptual sensitivity for the melodic, rhythmic and dynamic aspects of speech and music: aspects that linguists are inclined to categorize under the term ‘prosody’, but which are in fact the building blocks of music. Only much later in a child’s development does he or she make use of this ‘musical prosody’, for instance in delineating and subsequently recognizing word boundaries. In the essay shown below I try to make a case for ........ Read more »

The Life-Spans of Empires

by Samuel Arbesman in arbesman.net

I recently published my first history article. Titled The Life-Spans of Empires, it’s published in the delightfully-named journal Historical Methods: A Journal of Quantitative and Interdisciplinary History. Using a fun dataset I unearthed from some articles in the Nineteen Seventies, I explore the lifespans of empires, and their similarities to other complex systems: The collapse [...]... Read more »

The 30something Brain

by Neuroskeptic in Neuroskeptic

Brain maturation continues for longer than previously thought - well up until age 30. That's according to two papers just out, which may be comforting for those lamenting the fact that they're nearing the big Three Oh.This challenges the widespread view that maturation is essentially complete by the end of adolescence, in the early to mid 20s.Petanjek et al show that the number of dendritic spines in the prefrontal cortex increases during childhood and then rapidly falls during puberty - which p........

Sonority and Sex: Why smaller communities are louder

“Not all psychopaths are in prison. Some are in the Boardroom.”

by Rita Handrich in The Jury Room

When Robert Hare casually uttered the above statement, it caused small shock waves through the media. We are all familiar with psychopaths who end up in prison but we tend to not consider the reality that “they” walk among us. Recently, a study of 203 executives was conducted as part of a larger effort at [...]

Contra Deus ex Machina

by Cris Campbell in Genealogy of Religion

In Ars Poetica (“The Art of Poetry”), the great Roman lyricist Horace counsels against using gods to resolve thorny plots. The deus ex machina is simply too tidy and unbelievable. When gods swoop in to save the day, the mundane becomes sacred. Metaphysics to the rescue.

I was reminded of Horace’s enduring wisdom by two recent [...]... Read more »

Swedes move to the city, but don’t leave the forest behind

by Tim De Chant in Per Square Mile

If there’s one thing that comes to mind when you think of Sweden besides Ikea and meatballs, it’s probably forests. They cover nearly 70 percent of the country. As a result, Swedes have a very close relationship with their forests, though the nature of it has changed in the last few decades. Swedish forests have [...]... Read more »

Breakfast Skipping and Change in Body Mass Index in Young Children

As mothers everywhere know, breakfast is the most important meal of the day. However, as scientists, we want empirical evidence. Breakfast has been associated with several health outcomes, ranging from increased academic performance, to improved quality of life, as well as enhanced dietary profiles. While many cross-sectional studies have found that those who skip breakfast are more [...]... Read more »
