The myths about hydration

I grew up in Sri Lanka, a tropical country where the days were hot and one perspired a lot. And yet, there was little fear of dehydration. We drank water with meals and the occasional cup of tea but no one carried around bottles of water. Even when my friends and I played cricket all day, we drank when we were thirsty but that was about it. The idea that dehydration was a danger lurking that had to be staved off constantly was foreign to us.

When getting even leads to disaster

We know that people can act irrationally out of anger, reacting completely out of proportion to some real or imagined slight and doing dangerous and threatening things as a result. The most obvious examples are of road rage, but we also have cases of people harming and even killing others in domestic or neighborhood disputes. But in most of those cases, people are acting out of anger.

Can Trump lose among many subgroups and still win?

Some years ago, there was an odd feature of the scores on the SAT exam that students in the US take in large numbers and that many colleges use as one of their admission criteria. They found that the overall average SAT score was declining but that when the scores were disaggregated by ethnicity, the average scores of every subgroup (white, black, Hispanic, Asian) was rising.

How Roger Ailes got taken down by a ‘dumb blonde’

I mentioned in a previous post that my schadenfeude has limits when it comes to actual physical harm done to people and their families. But I have no limits to my enjoyment when it comes to how the odious, sexist, serial harasser Roger Ailes of Fox News got his comeuppance at the hands of someone who was widely seen as a dumb blonde. As I have noted before, former Fox News host Gretchen Carlson may have played a dumb blonde on her network but she is no fool.

The Trump campaign message becomes clear

So on Wednesday we had Donald Trump going to Mexico and meeting with their president Enrique Pena Nieto. Following it, he lavishly praised the Mexican people and said that the two had a cordial discussion, and that they did not discuss the wall or who would pay for it (something that the Mexican president later contradicted), suggesting to observers that he was going to change his approach on the divisive issue of immigration.

Rules for elevator behavior

It is interesting how conventions quickly develop for situations where people are put in close proximity, such as in elevators. There is even a name for the study of how people relate to others in public spaces: proxemics. This post looks at what we know about elevator behavior, such as how people arrange themselves as they enter, that people look at the numbers, possibly as a way to avoid eye contact with others, and that “Men leave more space between themselves and other men than women do with other women”.

Resurgence of polio

We have come really close to eradicating the deadly disease of polio and so any setbacks have to be viewed with concern. NPR’s Jason Beaubien, who has been doing some excellent reporting on health issues in Africa, says that the recent discovery of two new cases in the northeast of Nigeria (near the border with Chad) has health experts worried because that country had gone for two years without any cases and was on track to be next country to be declared polio-free.

The voting population that matters gets smaller

In a previous post, I wrote about how voter volatility has dropped sharply beginning with the 1996 elections, resulting in much greater stability in voter patterns. This has resulted in the cementing of party preferences in about 80% of the states leading to a semi-permanent red state-blue state map of the US, with just a handful of about 10 states (Ohio, Florida, Pennsylvania, Virginia, and Wisconsin being the largest of this small group) considered swing states whose outcome is now considered to be still up for grabs.
