Start the Week - What’s Your Type?

It’s nearly a century since the Myers-Briggs Type Indicator was first conceived. It has gone on to become a multi-million pound industry categorising people from thinking introverts to feeling extroverts. But the mother-daughter team who came up with the idea had no psychological expertise and the test itself has no scientific basis, as the author Merve Emre explains to Tom Sutcliffe.

Our genes are the most important factor in shaping who we are, according to the psychologist Robert Plomin. He argues that DNA influences everything from physical traits to intelligence and personality, and that nature not only trumps nurture, but is the main driver of it too.

But the educationalist Naomi Eisenstadt argues that environment has a significant impact on children, especially in their early years. Eisenstadt was the first director of the Sure Start Unit when it was set up at the end of the 1990s and has been a government advisor on education and inequality. She questions whether there is any role for DNA testing in government policy.

More or Less: Behind the Stats - WS More or Less: Why are Lesbians More Likely to Divorce than Gay Men?

New figures reveal that same-sex divorce rates are much higher among women than among men. The pattern is the same in Belgium, the Netherlands, Norway, Sweden and the UK. Everywhere where there are statistics on same-sex divorce it is the same sex doing the bulk of the divorcing. Tim Harford discusses why this may be with Marina Ashdade, economist at Canada?s Vancouver School of Economics and author of ?Dirty Money?, a book which applies economic ideas to the study of sex and love.

More or Less: Behind the Stats - Loneliness; School Funding; Same-Sex Divorce.

This week BBC Radio 4?s All in the Mind programme announced the results of The Loneliness Experiment. It was a large survey conducted by the programme in collaboration with the Wellcome Collection. The largest survey into the issue of loneliness to date, said All in the Mind, while the accompanying BBC press release reported that ?The survey results indicate that 16-24 year olds experience loneliness more often and more intensely than any other age group. 40% of respondents aged 16-24 reported feeling lonely often or very often, while only 29% of people aged 65-74 and 27% of people aged over 75 said the same.? In the editors' notes, the press release cautions that ?This was a self-selecting sample, so people experiencing loneliness might have been more attracted to take part, inflating reported levels of loneliness.? But much of the reporting by other BBC outlets and the wider media was not so restrained. Tim Harford speaks to Deirdre Toher from the University of the West of England about why the survey's results need careful interpretation.

Listeners have been asking us to explain the schools funding row. When headteachers marched in protest at school spending last week, the Minister for School Standards, Nick Gibb, went on BBC Radio 4's Today programme to say "We are spending record amounts on our school funding. We are the third highest spender on education in the OECD?. BBC Education correspondent Sean Coughlan explains how he discovered that the OECD figure includes university tuition fees paid by students.

Is it true that "Polish Pilots Shot down 60% of German Aircraft on Battle of Britain Day"? Lizzie McNeill fact-checks this claim found on the side of a van.

New figures reveal that same-sex divorce rates are higher among women than among men. Tim Harford discusses why this may be with Marina Ashdade, economist at the Vancouver School of Economics and author of ?Dirty Money?, a book about the economics of sex and love.

Plus, what makes a listener loyal? A nine-year debate rages on.

Yuval Noah Harari offers his 21 lessons for the 21st century. In a wide ranging discussion with Andrew Marr, Harari looks back to his best-selling history of the world, Sapiens, and forward to a possible post-human future.

Technological disruption, ecological cataclysms, fake news and threats of terrorism make the 21st century a frightening prospect. Harari argues against sheltering in nostalgic political fantasies. He calls for a clear-sighted view of the unprecedented challenges that lie ahead.

This is Capitalism - Cassandras of the Crash

Ten years ago, the world watched as the biggest financial meltdown in history unfolded. The crash plunged the world into recession, lost millions of families their homes and its shadow still hangs over our politics today. And when the Queen went to the London School of Economics, she asked the question everyone wanted the answer to: why did no one see it coming? Aditya Chakrabortty, senior economics commentator at the Guardian newspaper, chairs a discussion between four economists who can claim they did.
