Diagnostic Errors

Diagnostic Errors result from focusing on details and failing to recognize a large pattern.

Alternative Facts in Medicine

Doctors' hygiene

While we are collectively freaking out over the Trump’s White House use of Alternative Facts, these kinds of “facts” have been floating around in medicine (and politics) for a long time. And it is instructive to take a look at how we as a society have been dealing with Alternative Facts in Medicine and what damage these “facts” have wrought on us individually and collectively. I propose the following formula for how Alternative Facts come to be: Desperate Need + Greed = Alternative Fact Medical Myths: Beliefs Based on Outdated Science To start, allow me to refresh your memory, for our history is full of myths when it comes to our heath and our diseases. Let’s begin with a bit of bloodletting. Bloodletting is almost as old as our civilization. Thousands of years ago (that’s thousands, with three zeros!), a healer’s first choice of treatment was to let out the “excess” blood from a patient. Be it a migraine, an infection, or a virus, a person who was probably too sick to object was cut with a lancet or some other easily available tool and weakened even further via blood loss. The Greek physician Erasistratus believed all illnesses were due…

Cultural Differences in Child-rearing or Abuse?

baby and cobra

I’ve written about cultural differences in child-rearing that from our, Western, point of view seem like child abuse. There’s the dunking of babies into freezing ice waters in Russia; and spinning children to improve something; and now I just saw these videos from India. and There is no question that if these were video-documented instances of child abuse in New York or Los Angeles, authorities would be knocking down doors to rescue these children. But in other cultures, is it different? Do we bear responsibility there?

“Thanks for choosing Apple”…not!

Apple Customer Service... Not

This last month, we had a bizarre customer service experience with Apple iTunes. It started on September 13th with a simple purchase that wasn’t fulfilled. It ended with us angry and frustrated for no reason. Apple was having a one-day promotion where they were selling movie bundles of 10 movies for $10 each. My husband couldn’t resist and purchased three of the six bundles on Apple TV. But the movies didn’t show up in our list of purchased movies. It’s not the first time we’ve bought movies; our credit card was up-to-date. Something technical had just gone wrong. So the next day, my husband submitted a customer service request with Apple iTunes. The Apple Customer Service rep said that he could see that the purchases had been made and said that other customers were having the same problem getting their purchases. He said that he would resolve the issue. But then, another strangely hostile customer service rep took over. He recanted what the previous rep had said, implied that my husband was a liar and said that he could tell that we had never purchased anything, and effectively told us to go get bent. The customer service interaction with Apple…

Review eBook: Affordances and Design

Manches a Gigots

Victor Kaptelinin, a Professor at the Department of Information Science and Media Studies, University of Bergen, Norway, and the Department of Informatics, Umeaa University, Sweden, just published an eBook with Interaction Design Foundation: “Affordances and Design.” I was asked to write a review of this book and provide some insights into using affordances in interaction design and HCI. Let me start by providing the definition of affordance as given by Donald Norman: In his eBook, Victor Kaptelinin provides the history of the idea of affordance from its initial introduction by James Gibson in 1977 to the present day. The eBook’s bibliography and reference section is a great place to start the exploration of this topic for anyone new to these ideas. Unfortunately, the book doesn’t help much if an individual is looking for some guidance on how to apply these ideas in practical situations during interaction design or HCI design. For clarity’s sake, allow me to give a very brief explanation of affordances, from their roots to the present time. When James Gibson first introduced the concept of affordances, he focused on physical environment — what actions are possible? And the set of these action were invariable — just because…

How Do You Know When Contractors are Lying to You?

Do you sometimes get that sunken feeling that your contractors are flat out making up statistics about your users on the spot? I do get that a lot…but until just a few days ago, I didn’t have the indisputable evidence. Slide below is from a Russian contractor Power Point deck explaining the user demographic breakdown for different forms of payment awareness among the 18 to 45 year-olds. The logo of the company which made this slide is blurred… But for those of you who don’t speak Russian, let me walk you through the slide. Horizontal variables are: Knowledge of the type of payment and Usage. The columns are: Credit Card Payments; eMoney; Internet Banking; non-Internet Currency (aka cash); and payments via SMS. 79% of the population of Russian cities with population of over 800,000 people (really?) know about SMS payment systems and 22% use them. While only 93% heard of “offline” cash!

Task Analysis and Product Design

Kids from India and Vegetable Choices

Imagine your were given an assignment to develop a product that could help people eat healthy. How would you go about creating such a thing? What would you need to learn/understand? What is the right medium or technology vehicle for such a product? How would you even start? Below is a very brief outline of how to get started and the key tools necessary for the job. Project Goals The first order of business is figuring out the business needs and goals: What is the product really supposed to do? You have to ask this even if you are the one who is the client on this project. But, most probably, you are working for someone else — the client — and you have to start by understanding what your client really wants to do. You can do that in several ways: Analyzing the Request for Proposals: On many such projects, there will be an initial document, something like an RFP, that outlines the business goals and desires of the client. While some RFPs are very detailed and fully fleshed out, most are not. There are many reasons for this. Some clients are worried someone will “steal” their ideas and…

Musings on Failure in School

The Math Obstacle In the past few years, reports came out showing strong correlation between failing Algebra and graduation rates — if a kid fails math, he/she won’t be getting their high school diplomas. Here are a few articles describing the studies: “Is Removing Algebra a Key to Reform?” by Daniel Duerden, August 13, 2012 “A Comprehensive Study of the Predictors of High School Outcomes: Why Some Students Graduate on Time While Others Drop Out”. “A Correlation Study of Accuplacer Math and Algebra Scores and Math Remediation on the Retention and Success of Students in the Clinical Laboratory Technology Program at Milwaukee Area Technical College” by James Manto, August 2006. “Is high school tough enough: Full report” by The Center for Public Education. There are many more… Some suggested that based on evidence, we might just want to drop the math curriculum from high school graduation requirement — if there’s a strong correlation, perhaps by removing math, we might remove the problem and more kids graduate. Obviously, I don’t think that this a great solution. But I do come across the math problem a lot as part of the educational evaluations I do in my small practice. What I see…
