Every year at around this time, tens of thousands of people take part in a kind of bird-watching marathon. From Canada to Latin America and throughout the United States, participants will get up in the middle of the night. Some brave frigid winter temperatures, and many do whatever else it takes to count as many birds as they can in 24 hours.
No matter how old people are, they seem to believe that who they are today is essentially who they'll be tomorrow.
That's according to fresh research that suggests that people generally fail to appreciate how much their personality and values will change in the years ahead — even though they recognize that they have changed in the past.
Daniel Gilbert, a psychology researcher at Harvard University who did this study with two colleagues, says that he's no exception to this rule.
The wind energy industry is dependent on something even more unpredictable than wind: Congress. Hidden in the turmoil over the "fiscal cliff" compromise was a tax credit for wind energy.
Uncertainty over the credit had lingered long before the last-minute political push, causing the industry to put off further long-term planning. So while the now-approved tax credit revives prospects for an industry facing tens of thousands of layoffs, don't expect to see many new turbines coming up soon.
People have been sharing food with strangers since ancient days, offering up the household's finest fare to mysterious travelers. Think Abraham and the three men of Mamre in the Bible and the folks who take in strangers after natural disasters like Hurricane Sandy. That deep tradition of generous hospitality has long been thought uniquely human.
If so, then bonobos, those gregarious African apes, may be more like us than we thought.
If a stranger attacks you inside your own home, the law has always permitted you to defend yourself. On the other hand, if an altercation breaks out in public, the law requires you to try to retreat. At least, that's what it used to do.
