Perception & Context

by  • 

It’s All About Context When it comes to real-estate, it’s location, location, location. When it comes to design, it’s context, context, context. Consider the following scenario: you are going shopping at Good Will. You see a brand new coffee maker for $10. “Oh My God,” you say, “that’s incredibly expensive!” You don’t buy it. You go to Starbucks and see the exact same coffee maker on sale for $120. You get it—how can you pass up such a bargain? In a different setting, the perception of price of the coffee maker resolves as cheap even as the actual price is higher. Why? Why do we care about the context in which the product is sold as opposed to some other intrinsic characteristic? There are people who buy empty Tiffany’s blue boxes and cases. Why? So they can place jewelry and other gift items in there. The mere fact of being inside a blue box makes those object more valuable—they work harder. Again, the perceived value it’s not just in the intrinsic characteristic of an object in a box, but rather in the combination of the two: the product and its context. If a gift-giver tells you that the present you’re…

Science vs. Media: Degree of Public Involvement

by  • 

Recently, there has been an explosion of public discourse (fueled by the media) on whether we should do away with tenure in our institutions of higher learning. The basic argument boils down to “tenured teachers can do as they please due to job security and education suffers as the result.” Tenured professors, we are told, focus on research and publishing incomprehensible articles aimed at a few individuals in the world who could even understand them. What’s the use in that, people ask? My son/daughter/neighbor’s kid are being taught by a TA (with poor language skills) while we pay thousands of dollars for the privilege of these children attending universities with all those lazy good-for-nothing tenured professors! You might say that my summary of this world-view is extreme and simplifies the ideas to their comic representation. But that’s the point: the articles (and the readers’ comments they inspire) are written to get an emotional response. The issues of tenure, of the research that these tenured professors are engaged in and the articles they publish, and of teaching styles are complex. To evaluate the contribution of a scientist to his field, one needs to have a certain amount of expertise in that…

Metacognition Failure: If I find it easy, it must not be important

by  • 

Making something easy to understand is extremely difficult. A good designer knows this, knows how hard one has to work to make something comprehensible and easy to use. Unfortunately, users and consumers of products (including education) tend not to get it. We live in society ruled by “More is Better” p-prim: more stuff is better, more money is better, more food is good, more medication is great…more, more, more. Movies, television, newspapers, magazines, all reinforce this idea in our minds. We live in a “super-size me” world. But this basic decision-making algorithm leads to very faulty reasoning. There are multiple corollaries to the “more is better” axiom: thick books without graphics are more educationally valuable, more important (this is based on research I did many years ago with 5th graders); longer essays are clearly better and should get higher graders (the students worked harder/longer on them); big words are better than small ones in expressing ideas (thus we get very pretentious writing); work should be judged by the time it took to complete and not by the quality of the results it produces; more expensive clothes (cars, stereos, etc.) are clearly more valuable (this is a true statement, but most…

Categorization & Context

by  • 

What is art? Do the objects in the images above form a category of “sculpture”? In Kindergarten, young students are taught a game: every kid brings an object to class; each student is asked to create two piles—the “in” group and “out” group—based on his/her own imagined set of rules; the other children guess the rules that make the category. It’s a great game. A collection of 20 objects can be sorted a staggeringly large number of ways: by color, by size, by use, by ownership, by gender, by taste, by feel, by name, by materials used in manufacturing, by the degree of fun, by shape, by temperature, by degree of reflectiveness or transparency, by the feelings they inspire, by history, by age, by weight, by dimensions, by utility, by the maker, by origin, or any other trait or combination of traits. This is a task that’s truly shaped by imagination. Categorization is a work of creativity. Guessing the rules of categorization is deductive reasoning at its best—scientists, detectives, and doctors do it everyday. But unlike the Kindergarten game, there’s usually no one to tell when the guess is wrong. How we perceive a group of objects depends on the…

Male Paternal Bonds

by  • 

Angier, N., (2010). “Paternal Bonds, Special and Strange.” Nytimes.com. Retrieved on 20 June 2010: http://www.nytimes.com/2010/06/15/science/15fath.html?_r=1 An article written by, Natalie Angier in the New York Times, Paternal Bonds, Special and Strange, begins by stating how men are proudly proclaiming the number of children they have to other men. Comparisons are made between humans and other primates such as monkeys that also proudly display their infants to impress other male monkeys. It is stated that this action is done to strengthen the bonds between men. Furthermore, the article discusses multiple studies that demonstrate how male primates care for their offspring. For example, some bird species are the sole keeper of their nest. The article aims to link parental care and offspring welfare. One study claims that baby handling can demonstrate how fathers can take charge, beat the odds, and expand the nest. The studies referenced provide examples of what the author calls, “dream daddies” and males “behaving dadly”. Conceptual Design Through this study we can see that male animal primates have an instinctual response to care for and flaunt their offspring. This appears to a revolutionary breakthrough in our understanding of linking men with caring giving. The biological and innate instincts…

A Curiously French Complaint

by  • 

Kirby, E. (2008). “ A Curiously French Complaint,” BBC News.  Retrieved on 2008/12/13. http://news.bbc.co.uk/go/pr/fr/-/2/hi/programmes/from_our_own_correspondent/7779126.stm Summary: This article focuses on the cultural differences between the French and British populations in regards to their medical care. Each culture has their own script of understanding, which people rely to set their expectations during a medical crisis. The author Emma experienced a cultural ‘shock’ during her first encounter with a French doctor due to her vastly different set of expectations. She visits a doctor in France due to the severity of a sore throat, where she is “diagnosed with a severe lung infection, mild asthma and had in my hand a prescription for six different types of medicine, an appointment at the local hospital’s radiology department and an emergency referral to a specialist in pulmonary disease (article).” Upon her return to Britain a few days later, she visits her family physician, who within a few minutes diagnoses her with only a ‘common cold.’ Her article then explains how the French expect a much more sever diagnosis to support their physical suffering. France is also the leading country of consumers who take prescription medications. While in England, there’s a more ‘keep a stiff upper lip’…
