Titanic vs. Lusitania: How People Behave in a Disaster

Titanic vs. Lusitania: How People Behave in a Disaster

disasters - TIME By Jeffrey Kluger, courtesy of TIME 

It’s hard to remember your manners when you think you’re about to die. The human species may have developed an elaborate social and behavioral code, but we drop it fast when we’re scared enough — as any stampeding mob reveals.

That primal push-pull is at work during wars, natural disasters and any other time our hides are on the line. It was perhaps never more poignantly played out than during the two greatest maritime disasters in history: the sinking of the Titanic and the Lusitania. A team of behavioral economists from Switzerland and Australia have published a new paper in theProceedings of the National Academy of Sciences (PNAS) that takes an imaginative new look at who survived and who perished aboard the two ships, and what the demographics of death say about how well social norms hold up in a crisis. 

The Lusitania and the Titanic are often thought of as sister vessels; they in fact belonged to two separate owners, but the error is understandable. Both ships were huge: the Titanic was carrying 2,207 passengers and crew on the night it went down; the Lusitania had 1,949. The mortality figures were even closer, with a 68.7% death rate aboard the Titanic and 67.3% for the Lusitania. What’s more, the ships sank just three years apart — the Titanic was claimed by an iceberg on April 14, 1912, and the Lusitania by a German U-Boat on May 7, 1915. But on the decks and in the passageways and all the other places where people fought for their lives, the vessels’ respective ends played out very differently.

To study those differences, the authors of the PNAS paper — Bruno Frey of the University of Zurich and David Savage and Benno Torgler of Queensland University — combed through Titanic and Lusitania data to gather the age, gender and ticket class for every passenger aboard, as well as the number of family members traveling with them. They also noted who survived and who didn’t.

With this information in hand, they separated out one key group: all third-class passengers age 35 or older who were traveling with no children. The researchers figured that these were the people who faced the greatest likelihood of death because they were old enough, unfit enough and deep enough below the decks to have a hard time making it to a lifeboat.…

Bacteria, Boids and Market Instability

Here’s some weekend reading in advance. Consider throwing away economic models based on the misconception that people behave rationally and start anew with the premise that we are like mindless bacteria. – Ilene

Bacteria, Boids and Market Instability

The Gaps Between People

Old-time economics saw investors as rational individuals, all behaving autonomously in a logical fashion, rather like Mr. Spock umbilically attached to Deep Thought. Today not even economists really believe that this is how people actually operate, but figuring out something better is a not insignificant task. Psychologists, however, have long known that what happens in the gaps between people is as important as what happens in the gaps between their ears – so is there something going on in the interactions between investors, which causes market instability?

One possible answer comes from the study of bacteria. Just as we might have suspected all along, stockmarket investor behaviour can be modelled by examining the way a bunch of brainless, single celled and barely animate creatures interested only in food and reproduction disport themselves on a Petri plate. Sometimes analogies are just too sweet.

Investing Earthquakes

The critical thing about any economic model is that it arrives at results that look like what we actually see in markets. Mostly the jargon fixated commentators who dominate the media are happy to talk in terms of business cycles when, in reality, the only cycles seen in most investing circles are the ones used by the boys and girls delivering lunchboxes. What we actually get, if we look at stockmarkets and stock prices, is something that looks like the readout we see from a seismograph when an earthquake occurs.

If we start by making a few assumptions about what investors actually do in real life – like, for instance, that they don’t behave rationally and that they tend to copy successful behaviour from people they’re closely connected to – we can rapidly create a model that produces outputs that look very different from those generated by models of people who behave independently and rationally. In fact the output of these models looks a lot like the readout we see from a seismograph when an earthquake occurs.

So it seems that the interactions between investors and how these interactions affect their willingness or otherwise to invest is the critical thing in these models.…

The Wall Street Journal on the business of high frequency trading:

A costly high-tech arms race in which HFT firms relentlessly compete to shave tiny fractions of a second off data transmission times has also hurt their bottom lines.

Revenue at HFT firms from U.S. equities trading is projected to be just $850 million this year, compared to $7.2 billion in revenue from U.S. stocks trading in 2009, Tabb Group says.

Techniques pioneered by the upstart traders are now common at old-line financial firms. Goldman Sachs, for example, had 600 human traders supporting its cash eq...

The Entire Medical Industry Is About To Change

By The Sovereign Investor. Originally published at ValueWalk.

The doctor straightened and pulled the stethoscope from her ears. “I don’t hear anything on the right side.”

Sometimes silence is a good sign. When it comes to listening to my husband breathing, it’s not.

One quick X-ray later and we discover that his right lung had collapsed. There was also air putting pressure on his left lung.

The fix was easy. The doctor inserted a slender tube into his chest, sucking out the air. His lung reinflated in a matter of minutes.

I caught the doctor later and asked her why this had happened. When the pain started, he’d been watching TV.

She shrugged and admitted that sometimes it was just something that happened to men who are tall and thin.

Of course, the answer to the question of “How do we avoid this?”...

Ukrainian Lawmakers Disclose $45 Million In Bitcoin Holdings

As Ukraine's crackdown on corruption continues, three lawmakers from Ukraine’s ruling party revealed this week that they own a combined $45 million in bitcoin, according to a report by RIA Novosti, a Russian foreign news service.

Their holdings came to light during mandatory financial disclosures by members of the Ukrainian parliament, part of an IMF-approved strategy to tamp down corruption in Ukraine. The country's democratic institutions, which were never very robust to begin with, have been further destabilized by...

This would be excellent news for AAPL and GOOG to a lesser extent although not inconsequential:

The App Economy Will Be Worth $6 Trillion in Five Years 

In five years, the app economy will be worth $6.3 trillion, up from $1.3 trillion last year, according to a report released today by app measurement company App Annie. What explains the growth? More people are spending more time and -- crucially -- more money in apps. While on average people aren't downloading many more apps, App Annie expects global app usership to nearly double to 6.3 billion people in the next five years while the time spent in apps will more than double. And, it expects the...
