Where Are My Chocolates?: The Role of Gift Giving on Valentine's Day
by Melissa Chernick in Science Storiented
I think that the day after Valentine’s Day is actually the best. After all, chocolate is 50 percent off. However, using the holiday as an excuse to delve into the myriad of studies that attempt to explain the complexity of human attraction and relationships is pretty fun. Last year I examined moves, specifically some fly dance moves and rather cheesy pick-up lines. Today, I think I’ll explore gift giving.In the field of animal behavior, gift giving (or nuptial gifts) is practically its own s........ Read more »

Diversity and persistence of group tags under replicator dynamics
by Artem Kaznatcheev in Evolutionary Games Group
Everyday I walk to the Stabile Research Building to drink espresso and sit in my cozy — although oversaturated with screens — office. Oh, and to chat about research with great people like Arturo Araujo, David Basanta, Jill Gallaher, Jacob Scott, Robert Vander Velde and other Moffitters. This walk to the office takes about 30 […]...

Who Are You Wearing?: Does Competition Affect How Women View Luxury?
by Melissa Chernick in Science Storiented
What do you think of when I say “luxury consumption”? Probably something that requires a Robin Leach voice over, right? Now what if I ask you why these luxuries are so valued? Is it because they are of excellent quality? Aesthetically appealing? Highly exclusive? Next, consider the audience for the luxury – who is admiring who? And what does that luxury symbolize? Status? Wealth? Success?A recent paper in Evolutionary Psychology takes a look at these questions and has one of the best title........ Read more »

Who has the deepest voice amongst the Republican candidates for President?
by Doug Keene in The Jury Room
I watched the second Republican debate last week after reading two more articles on voice pitch and winning elections. Not coincidentally, I had to struggle to keep from focusing on who had the deepest voice among the candidates. We’ve written about this line of research before and tend to think of it as the Barry […]

Lumbersexuals with tattoos: Are they new and improved?
by Doug Keene in The Jury Room
Recently we blogged about an emerging demographic subgroup: the lumbersexual. After reading the flurry of mainstream media articles about this group, here is how we described them: “As far as we can tell, the lumbersexual is an urban male (typically White and heterosexual) who dresses like a lumberjack even though he is far from a […]

Misbeliefs, evolution and games: a positive case
by Sergio Graziosi in Evolutionary Games Group
A recurrent theme here in TheEGG is the limits and reliability of knowledge. These get explored from many directions: on epistemological grounds, from the philosophy of science angle, but also formally, through game theory and simulations. In this post, I will explore the topic of misbeliefs as adaptations. Misbeliefs will be intended as ideas about […]... Read more »

Most supernatural beliefs are about avoiding harm, not bringing benefit
A survey of supernatural beliefs across cultures around the world has found that beliefs involving hazards and harms were about 50% more common than beliefs about benefits, opportunities and other good things.

Will You Be My Valentine?: Making All the Right Moves
by Melissa Chernick in Science Storiented
My Valentine’s Day themed posts have been both popular and fun to write. In last year’s Getting a Date for Valentine’s Day series, you learned that you should wear something red, gaze without being creepy, tell a good joke before walking up to your potential date who is preferably standing next to some flowers, and then open with a unique request to segue into asking them out. But that isn't the end of the story. Oh no, there are many more things that you can do to attract that special so........ Read more »

Cataloging a year of blogging: the philosophical turn
by Artem Kaznatcheev in Evolutionary Games Group
Passion and motivation are strange and confusing facets of being. Many things about them feel paradoxical. For example, I really enjoy writing, categorizing, and — obviously, if you’ve read many of the introductory paragraphs on TheEGG — blabbing on far too long about myself. So you’d expect that I would have been extremely motivated to […]... Read more »

Journal Club: Halfsider: a bizarre half-male half-female bird
by GrrlScientist in Maniraptora
SUMMARY: A “halfsider” -- half male and half female bird -- has been mentioned in the news over the holidays. More properly known as bilateral gynandromorphs or tetragametic chimæras, these unusual birds are actually two genetically distinct individuals -- twins -- fused into one being. But what is it like to be such an individual? A recently published paper shares observations of the behaviour and social life of one such individual living in the wild.... Read more »

The “A,B,Cs” of Interests and How You [Lawyers] Can Know Them
by Dan DeFoe in Psycholawlogy
You [lawyers] have interests. Interests provide us potent motivation for goal-oriented behavior. We should not ignore them because interests, a very important individual difference trait variable, “are powerful predictors of educational and career choice, performance, and success”. A recent review of psychological science literature by leading scholars provides a concise summary of current knowledge [...]

Cross-cultural variation in men’s preference for sexual dimorphism in women’s faces
by Farid Pazhoohi in Epistemophil
Both attractiveness judgements and mate preferences vary considerably cross-culturally. We investigated whether men’s preference for femininity in women’s faces varies between 28 countries with diverse health conditions by analysing responses of 1972 heterosexual participants. Although men in all countries preferred feminized over masculinized female faces, we found substantial differences between countries in the magnitude of […]... Read more »

Sex smells: pheromones in humans
by neurosci in Neuroscientifically Challenged
By the middle of the 20th century, biologists had become aware of a unique type of communication occurring among insects. The communication involved the secretion of substances that were similar to hormones in some ways, but also very different. While hormones are secreted into the bloodstream to elicit some reaction in the body, these substances exit the body and are used to elicit a reaction in a conspecific (another organism of the same species). They were given the nam........ Read more »
