Researchers Howard Friedman and Leslie Martin report their conclusions in a new book, The Longevity Project. "Everybody has the ideas — don't stress, don't worry, don't work so hard, retire and go play golf," says Friedman, a psychology professor at University of California-Riverside. "We did not find these patterns to exist in people who thrived."

At the core of their 20 years of research is a study started by Stanford University psychologist Lewis Terman in 1921. Terman died in 1956, but other researchers carried on the study. One participant was biologist Ancel Keys, whose life-long work helped popularize the Mediterranean diet. He died in 2004 at age 100. He enjoyed gardening as an activity much of his life.

if your activities rise or stay high in middle age, you definitely stay healthier and live longer," says Martin, a research psychologist at University of California-Riverside.

I return to the Guardian online site expressly to search for those elusive articles on Wisconsin. The main page has none. I click on News – US, and there are none. I click on ‘Commentary is Free’- US, and find one article on protests in Ohio. I go to the New York Times online site. Earlier, on my phone, I had seen one article at the bottom of the main page on Wisconsin. By the time I managed to get on my computer to find it again however, the NYT main page was quite devoid of any articles on the protests at all. I am stumped; clearly, I have to reconfigure my daily news sources and reading diet.

It is not that the media is not covering the protests in Wisconsin at all – but effective media coverage in the US at least, in my view, is as much about volume as it is about substantive coverage. That week, more prime-time slots and the bulk of the US national attention were given to Charlie Sheen and his crazy antics (whatever they were about, I am still not too sure) than to Libya and the rest of the Middle East, or more significantly, to a pertinent domestic issue, the teacher protests  - not just in Wisconsin but also in other cities in the north-eastern part of the US.

In the March 2nd episode of The Colbert Report, it was shown that the Fox News coverage of the Wisconsin protests had re-used footage from more violent protests in California (the palm trees in the background gave Fox News away). Bill O’Reilly at Fox News had apparently issued an apology – but how many viewers who had seen the footage and believed it to be on-the-ground footage of Wisconsin would have followed-up on the report and the apology? And anyway, why portray the teacher protests as violent?

Invisibly but quickly, the Internet is changing. Sites like Google and Facebook show you what they think you want to see, based on data they've collected about you.

The filter bubble is the invisible, personal universe of information that results--a bubble you live in, and you don't even know it. And it means that the world you see online and the world I see may be very different.

As consumers, we can vary our information pathways more and use things like incognito browsing to stop some of the tracking that leads to personalization.

Just how far divorced from reality we are was shown recently in an elegant study by Oriel Feldmanhall, a PhD candidate at the MRC Cognition and Brain Sciences Unit at Cambridge University, England. She's just presented the research at the Annual Meeting of the Cognitive Neuroscience Society in San Francisco, California.

she studied two groups of people. The first group she asked them to imagine a scenario where they would get paid a small sum to deliver painful but harmless electric shocks. 64% said they would never deliver a shock, and on average the participants would only deliver enough shocks to earn a paltry £4. The second group got the real deal. They actually administered the shocks, and saw the response on video (they were in an MRI scanner at the time). This time, a massive 96% of participants administered shocks. Those who saw video of the grimacing faces of their victims pocketed £11.55. Those who were spared that and only saw the hands walked away with a cool £15.77.

Brains scans vividly illuminated the emotional turmoil going on in the subjects who participated in the real experiment. They had a lot of activity in their insula, a deep, primitive part of the brain thought to be linked to moral intuition. People who did the pen-and-paper, hypothetical version had no such turmoil.

Even if individual researchers are prone to falling in love with their own theories, the broader processes of peer review and institutionalized skepticism are designed to ensure that, eventually, the best ideas prevail.

Modern science originated from an attempt to weed out such subjective lapses

Our individual responses to the conclusions that science reaches, however, are quite another matter. Ironically, in part because researchers employ so much nuance and strive to disclose all remaining sources of uncertainty, scientific evidence is highly susceptible to selective reading and misinterpretation.

One set of polls, conducted by the University of New Hampshire, focused on a set of rural areas, including Alaska, the Gulf Coast, and Appalachia. These probably don't reflect the US as a whole, but the pollsters had about 9,500 respondents. The second, published in the The Sociological Quarterly, took advantage of a decade's worth of Earth Day polls conducted by Gallup.

Both surveys asked similar questions, however, including whether climate change has occurred and whether humans were likely to be the primary cause. The scientific community, including all the major scientific organizations that have issued statements on the matter, has said yes to both of these questions, and the authors interpret their findings in light of that.

The UNH poll shows that a strong majority—in the 80-90 percent range—accepts that climate change is happening. The Gallup polls explicitly asked about global warming and got lower percentages, although it still found that a majority of the US thinks the climate is changing. Those who label themselves conservatives, however, are notably less likely to even accept that basic point; less than half of them do, while the majority of liberals and independents do.

As many of our readers and podcast listeners have now learned, author, colleague and friend Jennifer Michael Hecht has started an internet campaign on June 22nd using social media to accuse us of plagiarism.

Jennifer apparently believes that we in some form stole her ideas, as presented in her 2008 book, The Happiness Myth

We protested our innocence, emphasizing that the only areas of overlap between her book and our podcast concern a few very common topics about happiness (its treatment by Aristotle and Epicurus, so-called happiness “set points,” and the question of whether wealth is connected to happiness). These, we pointed out, are so fundamental to a discussion of happiness that they are practically mandatory in any treatment of it. It would be odd indeed to have a show on happiness and not mention the research on set points, or on income and happiness — sort of like talking about evolution without mentioning Darwin and natural selection. We also pointed out that said topics make up only a small fraction of those we discussed in the podcast, and of her book for that matter. These ideas are certainly not Jennifer’s original contributions (of which there are many genuine examples in her book); rather, they have been widely discussed in the media, academic journals, and in many popular press books, such as Stumbling on Happiness by Daniel Todd Gilbert, Authentic Happiness by Martin E. P. Seligman, and The Happiness Hypothesis, by Jonathan Haidt.
