Socializing expands brain size?

This is by no means an overnight phenomenon.

Scholars at Oxford have refuted the notion that all mammals over time developed larger brains.  Instead Dr. Susanne Shultz and Prof. Robin Dunbar found over a span of 60 million years that more social creatures, among them humans, had the most rapidly expanding brain sizes to cope with the complexity of collaboration, social norms and coordination.

“The research team analysed available data on the brain size and body size of more than 500 species of living and fossilised mammals. It found that the brains of monkeys grew the most over time, followed by horses, dolphins, camels and dogs. The study shows that groups of mammals with relatively bigger brains tend to live in stable social groups. The brains of more solitary mammals, such as cats, deer and rhino, grew much more slowly during the same period.”

They noted that the fact that cats’ brains did not expand while dogs’ and horses’ brains did, can be accounted for by the far more solitary lives that cats lead in relation to dogs and horses, which interact far more with humans.

Obviously, since these evolutionary anthropologists couldn’t go back in time to distinguish social cavemen from more solitary cavemen, it is impossible to tell whether the expansion of brain size was related to the average levels of socialization of a species or whether this same pattern would have held true at the individual level: with offspring of more social parents having larger brains than offspring of less social humans.

Nonetheless, food for thought…  The implication: get out and socialize and help our species to continue to grow our average brain size, although the results may not be noticeable within your lifetime.

The study is called “Encephalization is not a universal macroevolutionary phenomenon in mammals but is associated with sociality” (PNAS Journal, November 30, 2010, by Susanne Shultz and Robin Dunbar).  Abstract here.

Companies using social capital data for betting on people’s lives

The Wall Street Journal recently noted  how insurance companies (Aviva PLC, Prudential Financial, AIG) bet on whom to insure at what rates through data mining.  Much of the info gleaned from online purchases and other digital traces is more lifestyle: is the insurance applicant an athlete? a TV addict? a hunter?

But some of the information is social capital-related:

Increasingly, some gather online information, including from social-networking sites. Acxiom Corp., one of the biggest data firms, says it acquires a limited amount of “public” information from social-networking sites, helping “our clients to identify active social-media users, their favorite networks, how socially active they are versus the norm, and on what kind of fan pages they participate.”

For insurers and data-sellers alike, the new techniques could open up a regulatory can of worms. The information sold by marketing-database firms is lightly regulated. But using it in the life-insurance application process would “raise questions” about whether the data would be subject to the federal Fair Credit Reporting Act, says Rebecca Kuehn of the Federal Trade Commission’s division of privacy and identity protection. The law’s provisions kick in when “adverse action” is taken against a person, such as a decision to deny insurance or increase rates. The law requires that people be notified of any adverse action and be allowed to dispute the accuracy or completeness of data, according to the FTC.

The article also notes that Celent, an insurance consulting division of Marsh & McLennan, indicates that such online social-network data could be mined for policing fraud and in making pricing decisions: “A life insurer might want to scrutinize an applicant who reports no family history of cancer, but indicates online an affinity with a cancer-research group, says Mike Fitzgerald, a Celent senior analyst.  ‘Whether people actually realize it or not, they are significantly increasing their personal transparency,’ he says. ‘It’s all public, and it’s electronically mineable.’  “

We’ve written earlier about other life insurers using social capital data in making insurance decisions, but in those cases, the individual was being asked directly about his social and civic involvement.  [See also this blog post about social capital and healthcare.]

We applaud the life insurers for coming to the late realization that social capital data is strongly related to health, but strongly believe they should be more transparent about what they are doing.  Then it wouldn’t violate privacy concerns and it would have the added benefit of making the insured better aware of the positive health impact of being more involved civicly and socially, which might actually induce those who are less engaged to become more so.

Happiness: how to increase it, UK Government measurement

Flickr photo by greeneydmantis

Two interesting updates on happiness research:

1) Being in the present increases your happiness.  A somewhat surprising finding since  one would think that daydreaming about a Tahitian vacation, a Carlton Fisk’s memorable 1975 world series home run for the Red Sox, or recalling something hilarious one’s children said, would increase your happiness.  But social psychologists Daniel Gilbert and Matthew Killingsworth (both from Harvard) found, using an iPod app called trackyourhappiness, that the Buddhists were indeed right.  Dwell in the present and be mindful.  Trackyourhappiness beeped 2,200 volunteer subjects at various times of the day and asked them describe what they were doing, with whom, and how happy they were.  The researchers analyzed the quarter of a million datapoints to determine what activities provided the greatest or least happiness.

Excerpt:

When asked to rate their feelings on a scale of 0 to 100, with 100 being ”very good,” the people having sex gave an average rating of 90. That was a good 15 points higher than the next-best activity, exercising, which was followed closely by conversation, listening to music, taking a walk, eating, praying and meditating, cooking, shopping, taking care of one’s children and reading. Near the bottom of the list were personal grooming, commuting and working.

When asked their thoughts, the people in flagrante were models of concentration: only 10 percent of the time did their thoughts stray from their endeavors. But when people were doing anything else, their minds wandered at least 30 percent of the time, and as much as 65 percent of the time (recorded during moments of personal grooming, clearly a less than scintillating enterprise).

On average throughout all the quarter-million responses, minds were wandering 47 percent of the time….

”I find it kind of weird now to look down a crowded street and realize that half the people aren’t really there,” Dr. Gilbert says.

Of course, it might well be that the mind wanders because the underlying activities are less “scintillating”; it’s hard to say whether being in the present for commuting or grooming would dramatically increase the happiness levels of doing those activities, although it might reduce traffic accidents and grooming accidents…

See “When The Mind Wanders, Happiness Also Strays” (NY Times, 11/16/10, by John Tierney)

See here for a recent summary post on happiness research.

2) The British government has followed up on Prime Minister David Cameron’s interest in wellbeing and will begin measurement this year.  The UK government follows countries like Bhutan and Canada in regularly measuring this concept. France has also been recommended to take similar action from a high-powered academic commission advising French President Nicolas Sarkozy; Sarkozy announced in 2009 that he plans to measure happiness and wellbeing as part of France’s economic progress in the near future.

A Guardian piece notes that there is some ” ‘nervousness’… in Downing Street at the prospect of testing the national mood amid deep cuts and last week’s riot in Westminster…”  Cameron has indicated that tracking wellbeing is as important as ever during a downturn, and his commitment to integrate wellbeing centrally into government policy.

The government is charging the national statistician Jil Matheson with crafting the exact happiness questions to add to the Office of National Statistics’ ongoing household survey. Cameron has asked for regular measurement of “subjective wellbeing” (including happiness) and how well Brits are meeting their “life goals”.

The new data, to begin being measured in Spring 2011, may be published quarterly like British crime data, and will be coupled with other social measures like social capital to provide data on Brits’ quality of life.

John Helliwell “told the Guardian: ‘The UK plans are putting into action the two most important elements of the Stiglitz/Sen report: systematically measuring subjective wellbeing as part of a broader national accounting system, and using these data to inform policy choices.’  “

Import of best friends and socializing at work

Bob Putnam and I were recently meeting with Jim Clifton, CEO of Gallup.

Jim related an interesting “social capital” finding of Gallup.  That employees having a ‘best’ friend at work is vitally important to the success of a company.   Gallup faced considerable opposition to this question from CEOs who didn’t want Gallup asking this of their employees and who said they wanted their employees focused on doing their job, not developing a best friend at work.  Gallup tried reformulating the question to ask about ‘close friends’ at work, but found that this question was not nearly as predictive of a whole host of beneficial outcomes.

Those who had best friends at work (only 30% of Americans) were 7 times more likely to be engaged with their job, they exhibited higher sales and profitability, better engaged customers,  produced higher quality work, had greater commitment to the firm’s mission,  had better safety records (since friends often made sure they were complying with safety precautions), were happier at work, and had a higher chance of sticking with a firm.  If workers didn’t have a best friend, only 8% of them were engaged in their job.

Gallup also observed that employees who report having a best friend at work were:

  • 43% more likely to report having received praise or recognition for their work in the last seven days.
  • 37% more likely to report that someone at work encourages their development.
  • 35% more likely to report coworker commitment to quality.
  • 28% more likely to report that in the last six months, someone at work has talked to them about their progress.
  • 27% more likely to report that the mission of their company makes them feel their job is important.
  • 27% more likely to report that their opinions seem to count at work.
  • 21% more likely to report that at work, they have the opportunity to do what they do best every day.

Gallup also found other social capital measures to be key to successful business organizations: having someone at work who cares about you, and having a mentor.

This finding gibes with workplace social-capital work that we have done and work of John Helliwell and Haifang Huang on the importance of trust of management in ensuring wellbeing of those at the workplace.

Two MIT researchers (Sandy Pentland and Benjamin Waber) also found using sociometers that even apparently idle workplace socializing increases productivity.  [Here's a link to earlier work of Sandy Pentland.]

Gallup also noted that they do 1000 US surveys a day and one question they ask is for people to give their weight, and they can actually see American obesity inching up day by day.

In two other social capital results, not focused on the workplace:

1) Gallup has also found that people need 6 hours of social time a day (on the phone, at work, at home, talking to friends, on e-mail) in order to “thrive”.  with no social time in a day, one has an equal chance of having a good or bad day, but with 3 hours of social time, the chance of a bad day drops to 10%.

2) Through Gallup we also learned of an experiment by researchers at Ohio State University  on the connection between stress and physical health.   42 married couples were given 8 tiny identical blisters; the skin was removed and a suction devices put on top that monitored the rate of healing. Researchers found that in marital relationships with hostility, wounds took almost twice as long to heal.  The magnitude was shocking; such hostility and lack of relational closeness could rival or exceed traditional physical factors.

2010 voter turnout up, but not for youth and blacks (UPDATED)

Preliminary evidence suggests that voting turnout among all Americans was up in the November 2010 election.  Compared with the last non-presidential election (2006), both voting turnout experts (Curtis Gans and Michael McDonald) agree that turnout among eligible voters rose 1.1-1.2 percentage points (based on preliminary estimates that will obviously change as all ballots are counted and certified). Regardless of whether one likes the outcome in 2010, it is civic good news that more Americans got involved.

Preliminary evidence suggests electoral turnout rose in at least nine states, and significantly in Texas, Florida and Minnesota.  Ohio and Pennsylvania, among other states, seems to have experienced a turnout decline.  [Curtis Gans projects voting turnout at 42 percent of registered voters; Michael McDonald believes that 41.5% of voting-eligible Americans turned out to vote.]  Note: McDonald has now lowered his turnout estimate 1.2 percentage points to 40.3% (VEP Highest Office Turnout, as of 11/8/10).

But the bad news is what voices are being heard or not heard. Voting turnout rates were down among young voters (18-29) and blacks made up a lower percentage of voters in 2010 than in 2008 when Obama’s candidacy excited African-Americans to vote.  For example, blacks made up 12% of voters in 2008 and appeared to make up just 10% of voters in 2010 (based on exit polls).  This drop, if it holds up in more authoritative numbers like the Current Population Survey would  negate this encouraging finding reported in 2008 that the black-white voting gap had disappeared.    [Exit polls suggest that Hispanics maintained their share of the electorate, rising from 7% in 2008 to 8% in 2010, although one would have to compare this rise against their expanding voting-eligible numbers to truly understand whether their political voice was diluted, and if so, how much.]  It wasn’t a simple story of the richest folks’ accounting for more of the votes, since those earning $100,000 or more accounted for 26% of the votes in both 2008 and 2010, but due to the elimination of restrictions on corporate campaign contributions in the wake of the 2010 Citizens United case, the wealthy disproportionately had chances to influence election outcomes even before voters got to their polling places.
