Turning junk mail into news



When civilian journalists -  bloggers to you and me - write a new post, they tend to send the link out on Twitter and hope that people will retweet and share it. If that doesn't work, they can try badgering, bullying, bribery and blackmail - but if the readers don't think it's up to scratch, they won't pass it on. You could call it raw news judgment.
Professional journalists pass similar verdicts dozens of times every day. Reporters are bombarded with handouts, emails and phone calls from PR types trying to sell this soap, that survey, and  the other view on what some politician said yesterday. Just like the people on Twitter who glance at a link and move on, the reporter needs to be convinced before passing  this unsolicited information to a wider public.
Most handouts are just sophisticated junk mail, with commensurate news value. For a start, they invariably present the one-sided view of someone with a vested interest or an axe to grind. On busy news days, they'll be cast into the trash, but in quieter times they may win a second look. This weekend, with little more than a rainy bank holiday and some election fallout vying for news space, news editors will pay slightly  more attention to the dangers of drinking tonic water, while PRs worth their salt will time their pitches on how to improve the transport system.
Since none of this is strictly news, a story's chances of appearing in print will rely on how interesting rather than how important it is. And that, of course, is an entirely subjective judgment.
Sadly for the diversity of the press, these judgments are largely made by the same sorts of people. Our national newspaper editors are, with one exception, white men, mostly in their forties and fifties. Backbenches and newsdesks are also still male-dominated, while women continue to be allowed  - and I use the word advisedly - their heads predominantly in the features departments. And so, the news agendas have similar threads running across all breeds of paper, a lot of them born of received wisdom rather than genuine belief - a journalistic version of case law, if you like.
One perennial that should have died off 20 years ago still flowers: the housing market. As with all plants, it blooms more profusely when under stress - in this case when there's little else to fill the paper.
I was rebuked in the 1980s for failing to run a house price index story. "House prices are of abiding interest to all our readers," I was told. That might have been true then, but the surveys seemed meaningless, other than to provide dinner party chat fodder: after all, who lived in the 'average' house?  In the 80s and 90s, prices were either soaring or plummeting, and there  were real differences day to day, not just month to month, with couples either celebrating huge paper profits and dreaming of luxurious retirement or despairing as their biggest asset shrunk before their eyes. People stopped seeing a house as a place to put down roots and build a family and a life, but as a step on a ladder that led to the rainbow with its pot of gold on the side.
That ladder idea still pertains, though these days it has only a couple of rungs leading from living with mum and dad to a modest house via a starter home.

                                                     

The market has been pretty stable - stagnant might be a better word - for years, but the newspapers' obsession remains undiminished. The same goes for interest rates - or rather for mortgage rates; no one gives a stuff about savers.
On Tuesday The Times splashed on the news that more than a million homebuyers would see their repayments increase by hundreds of pounds a year because a clutch of lenders,  including the Halifax with 850,000 borrowers, were raising their variable rates. This would, the report said, add £55 to the monthly cost of an "average" £200,000 mortgage.
There was nothing in this story about what, if anything, was happening to savers' rates - even though there are roughly seven times as many savers as borrowers in this country and millions of pensioners struggling on fixed incomes and dismal annuities. The rates are going up because money is costing more on the wholesale market. It's all about profit - and in the case of the Halifax, getting some dosh back to the taxpayer.
Savers continue to receive a paltry 1 or 2% return on their money. You might read a bit about this in the personal finance pages, but rarely does the issue feature on the news pages. After all, news editors tend to be  family men trying to make ends meet as the mortgage goes up. And these young men haven't lived through the era of 10, 12 and 15% interest rates; to them, anything above 4% feels like usury.



And what's happening to property prices? Well, the Nationwide published its April figures today  (above) and  the Halifax is due to produce its statistics in the next few days - and they're bound to get big play, it being a quiet news weekend. So was I wrong in the 80s? Do they have value? Judge for yourself from the March figures.

The Halifax reported that prices went up 2.2% in March, after a 0.4% fall in February.
Prices in the first three months of the year were 0.6% lower than in the same quarter last year. The average house price in March was £163,803.

The Nationwide reported that prices went down by 1% in March, after a 0.4% increase in February.
First quarter prices were 0.2% up on the same three months of 2011.
The average house price was £163,327.

The Land Registry reported that prices were down by 0.6% in March after an 0.1% increase in February.
The average house price was £160,372.

Do you feel wiser for that? The only vague area of consistency is the average house price. But, as I asked earlier, what is an average house? You are looking at a mean price taking into account castles in Scotland, mews houses in Kensington, semis in Swansea and studio flats in Hull.
Yet still newspapers  insist on publishing these statistics - although whether they appear as  fillers in the business pages or splashes to the entire paper depends on whether there's anything else to fill the space.
Of course we have to publish unemployment and inflation statistics monthly. But, come on, these house price figures are just another bit of PR junk mail and they should be treated with the scepticism that would be meted out to any other single-interest survey. The very least we can do is to offer our readers the service of researching a little deeper. For example, doesn't it strike you as interesting that Leah Milner in The Times told us on Tuesday that the "average" loan of £200,000 would cost £55 a month more. An average loan of £200,000? When the average house costs £163,000 - and  at a time when banks are reluctant to lend more than 80% of its value?




And so to Madeleine. As expected, the McCanns surfaced for the anniversary. And just as no news editor dares shy away from house prices, nor will he risk missing the latest performance from this circus.
Let's be clear on this. Just because it's the anniversary, there is no obligation to run a Madeleine story. Just because the McCanns speak, there is no obligation to record their every utterance. Just because a television programme broadcasts an interview, there is no obligation to reproduce the transcript in print. But we just can't help ourselves, can we?

So, of course, we had two papers splashing on the missing child today, while the Express exercised the utmost restraint and contented itself with a front page picture puff.
Was there any news? Well, Gerry told Lorraine Kelly's television programme that he had never felt as confident as he did now that the mystery would be solved. And Kate said that the younger twins had vowed to find their big sister.
Come again? The twins are seven. They can see how preoccupied their parents are; children of that sort of age are sensitive and eager to please. It's easy to imagine little Sean saying "Don't worry Mummy, if you don't find Madeleine, Amelie and I will keep on looking until we do."  Now let's go and play football please.
How much store can we set by such promises? In a family dominated by its absent member? Is this not the sort of placatory stuff you'd expect from a child whose life is overshadowed by an older sister he never knew? When my daughter was that age, she invented her own personal rescue service,  Horse Help Need. When we discovered on returning from a trip to France that the back of the new car and all its contents were smothered in spilt washing liquid, she rushed into the house. We hoped she had  gone to fetch a mop or cloth. But no, she came galloping out in her  Horse Help Need hard hat and badge and went charging round the car promising help without doing anything practical, like helping to unload the sodden holdalls. That's what seven-year-olds do. Their pledges on unending quests are to be taken lightly.

It wouldn't be a proper anniversary, though, without a 'new lead', and today's offering was a taxi driver who claimed to have had Madeleine and four adults in his cab on the night of the disappearance. Now this is an interesting one. "I'm certain it was her," said Antonio Castela, 72. He had picked up the child, three men and a slim blonde woman  from a taxi rank in Monte Gordo -  about an hour from Praia da Luz, where the McCanns had been staying -  and taken them to an hotel two miles away. There they had got into a waiting blue jeep with foreign number plates and driven off. He was sure it was Madeleine because the little girl was wearing pink Eeyore pyjamas and he noticed the mark in her eye - it was the same as one his son had. 
Mr Castela  had told the police all this at the time, but "I never heard anything from them again. they didn't seem to take me seriously and never questioned me. They simply took down the details and that was it. I'm amazed nobody has ever asked me what I saw that night."
Tut, tut. Those hopeless Portuguese police again. Those lazy coppers who weren't chasing the hundreds of sightings reported in the early days of the hunt.
What do the McCanns make of Mr Castela's story? Their spokesman Clarence Mitchell said: "Mr Castela did absolutely the right thing at the time by reporting his sighting. It is clearly deeply shocking that he now tells us he hasn't been interviewed once by a detective in five years." The whole account would doubtless be scrutinised by the new Met review of the case.
Shocking indeed. Is this the same taxi-driving Mr Castela who told his story to The Sun in 2008? The same Mr Mitchell who then discounted the evidence "primarily because the timings are entirely wrong"?
Yes, the taxi driver story that appeared in the Evening Standard, Express and Star today is almost identical to the one published in The Sun and on the Telegraph and Standard websites four years ago. Then Mr Castelo was quite convinced not only that it was Madeleine sitting on the lap of a rear-seat passenger, "staring straight ahead as though doped", but also that the slim blonde woman was Mrs McCann and that the person in the front passenger seat was Robert Murat - a man whose life was turned upside down as people scattered wild accusations  and innuendo willy nilly, with no concern for the consquences.
For heaven's sake. When are we going to get real and do some proper journalism or let well alone?

Food for thought




Fantastic news yesterday: swap your breakfast bacon for a kipper and you might live forever.
You think I'm kidding? Well it's in the papers and it comes out of a Harvard study, so it surely must be true.
Replacing red meat with poultry, fish or vegetables cut the risk of dying by up to a fifth 
writes the Telegraph's medical editor.
Replacing one serving of red meat with an equivalent serving of fish reduced mortality risk by 7 per cent.
reported the Daily Mail.

So, too, in various forms did the Guardian, the Independent, the Chicago Sun-Times, the Sydney Morning Herald and the American news networks. 
But you'd be forgiven for missing this earth-shattering gem as it generally appeared halfway through a story about how eating roast beef will kill you - and how eating sausages will kill you faster.  A story that the Telegraph  splashed under the heading
Red meat is blamed for one in ten early deaths 

Now I always thought that death was 100 per cent certain. So the news that a bit of fish 
might cut that risk to 93 or 80 per cent (depending on which paper you're reading) is pretty amazing.
On the other hand, it seems that if you have bacon for breakfast or a hotdog for lunch every day you'll be dead in a fortnight:
For each serving of processed meat...the risk of dying from heart disease rose by 21 per cent.

The risk increases by 21% with every serving? Surely not?
Of course I'm being facetious. But these linguistic infelicities demonstrate the dangers in translating scientific research into a news story - and there were many pitfalls in this story.

It's understandable that the findings of Frank Hu's team at the Harvard School of Medicine should be  afforded international coverage. A huge study -  covering 120,000 people over more than twenty years -  by the world's foremost university demonstrates that a fundamental element of the Western diet could be lethal. Who could question the results?
But how many reporters actually read the paper produced by Mr Hu and published in the Archives of Internal Medicine along with 30-odd references and footnotes? And how many simply rewrote agency copy or a press release? The chances are that at least some  were relying on a precis of a precis of a precis. 
Did they speak to Mr Hu? Did they raise any questions? Well, the Telegraph, the Guardian, the Mail and the American and Australian news media all have the self-same quote from Mr Hu, so either he's extraordinarily consistent in his use of language or it came from a handout.

The conclusions reported across the media were that eating 3oz of red meat every day meant you were 13 per cent more likely to die "early" than if you didn't; that if you ate processed meat such as sausages or bacon, that risk was even greater. If you ate fish, poultry or vegetables instead, you would live longer. And if one in ten men had halved their meat intake they wouldn't have died.
The reader was not  told who took part in this study, what age or race they were, what their general health was, how the research was conducted, what might constitute an "early" death.

And so to the research. 
The Harvard team observed 37,698 male health professionals from 1986 (when they were aged between 40 and 75) until 2008. It also studied 86,644 female nurses from 1980 (then aged between 30 and 55) until 2008. None showed signs of cancer or heart problems at the start of the investigation.
Over the period of the study 8,926 of the men and 15,000 of the women died. In each case about a third of the deaths were from heart disease or cancer.
So what we know for sure is that  coronary disease or cancer killed nearly 6,000 men  before they reached the age of 97 and about 9,500 women  before the age of 83.
We also know from the published paper, though not from the press, that the participants were overwhelmingly white.
The sample is therefore 120,000 white Americans who all work in the same industry -  one that is known for stress, long hours and disturbed sleep.  They may therefore start off with a raised (or, indeed, reduced) risk of heart disease or cancer. And while having a huge sample from the same background may be useful as a constant, how can we assume that the results will apply to white Americans in all walks of life, to black bankers, Latino factory workers or Asian businessmen, let alone the entire Western population?


The methodology was to ask the participants to fill in a questionnaire  every four years, the key questions being how often they consumed various foods of a "standard portion size", with possible answers ranging from "never" to "more than six times per day".
For red meat, such as roast beef, the standard portion size was set at 3oz - which happens to chime roughly with health officials' view of the recommended maximum daily intake.
I'm not sure how I would have answered that. I don't eat meat every day, but when I do I'd look on 3oz as a pretty dismal portion. So say you have 6oz of roast lamb on Sunday, 3oz of  cold meat in sandwich on Monday and an 8oz steak on Wednesday, how do you report that?
The answers were analysed with allowances made for "variables" such as age, weight, whether the subject smoked or exercised or took vitamin pills or aspirin. This led the researchers to the assertion:  "Men and women with higher intake of red meat were less likely to be physically active and were more likely to be current smokers, drink alcohol and to have higher body mass intake."

From the analysis, the researchers concluded: 
We estimated that substitutions of 1 serving per day of other foods (including fish, poultry, nuts, legumes, low-fat dairy and whole grains) for 1 serving per day of red meat were associated with a 7% to 19% lower mortality risk. We also estimated that 9.3% of deaths in men and 7.6% in women in these cohorts could be prevented at the end of follow-up if all the individuals consumed fewer than 0.5 servings per day of red meat.
So they are not saying that red meat is to blame for one in ten deaths. They are saying that if all 37,000 men had cut their meat consumption to half the recommended maximum level, 538 of them - some of whom could  have been in their nineties - might not have died over the course of 22 years.

And what of that generalisation about smoking, drinking and general couch potatoery? Can you just discount all those factors as "variables" that have been taken into account without explaining how?

I once worked for a national newspaper editor who wearied of the endless Westminster soap opera being seen as the default splash. "Haven't we got a good health scare?" he would ask.
He knew what sold papers.  The thousands of comments appended to the various online reports of this study bear that out, so you can't blame the Telegraph for latching on to it; the only surprise is that the Mail and Express went with the drought instead. It's just that even the most authoritative research may not be all that it seems.

Mr Hu, however,  seems to know when he's on a winner. He simultaneously published another study - in another journal - that found that one can of fizzy pop a day increased the risk of heart disease in men by 20%. The subjects of his study? 38,698 health workers who were observed between 1986 and 2008. Fancy that! 
Now the thing is, were these cases of heart disease really the result of fizzy drinks - or the consequence of eating too many hotdogs? 
Or maybe that sweeping generalisation in the meat study was the true nugget of common sense: if you're a lardarse boozer who eats too much junk food, drinks too much Coke and doesn't move about enough, you may not make it to 97.
